Description
[0001] The present invention claims priority to United States
Provisional Patent Application entitled "Led Warning Signal Lights
and Communication System," provisional patent application Ser. No.
60/248,894 filed Nov. 15, 2000, which is incorporated herein by
reference in its entirety.
BACKGROUND OF THE INVENTION
[0002] Light bars or emergency lights of the type used on emergency
vehicles such as fire trucks, police cars, and ambulances, utilize
warning signal lights to produce a variety of light signals. These
light signals involve the use of various colors and patterns.
Generally, these warning signal lights consist of incandescent and
halogen light sources having reflective back support members and
colored filters.
[0003] Many problems exist with the known methods for producing
warning light signals. One particular problem with known light
sources is their reliance on mechanical components to revolve or
oscillate the lamps to produce the desired light signal.
Additionally, these components increase the size of the light bar
or emergency lights which may adversely affect the vehicle's
aerodynamic characteristics. Moreover, because of the relatively
poor reliability of conventional lighting and the complexity of the
present strobe rotational systems there is an increased likelihood
that a breakdown of the light bar or light source will occur
requiring the repair or replacement of the defective component.
Finally, conventional light bars and light sources require a
relatively large amount of electrical current during operation. The
demands upon the electrical power system for a vehicle may
therefore exceed available electrical resources reducing
optimization of performance or worse, generating a potential hazard
from shorted or over-heated systems.
[0004] Halogen lamps or gaseous discharge xenon lamps generally
emanate large amounts of heat which is difficult to dissipate from
a sealed light enclosure or emergency light and which may damage
the electronic circuitry contained therein. In addition, these
lamps consume large amounts of current requiring a large power
supply, battery, or electrical source which may be especially
problematic for use with a vehicle. These lamps also generate
substantial electromagnetic emissions which may interfere with
radio communications for a vehicle. Finally, these lamps, which are
not rugged, have relatively short life cycles necessitating
frequent replacement.
[0005] Another problem with the known warning signal lights is the
use of filters to produce a desired color. Filtering techniques
produce more heat that must be dissipated. Moreover, changing the
color of a light source requires the physical removal of the filter
from the light source or emergency light and the replacement with a
new filter. Furthermore, filters fade or flake over time rendering
the filters unable to consistently produce a desired color for
observation in an emergency situation.
[0006] These problems associated with traditional signaling lamps
are exacerbated by the fact that creating multiple light signals
requires multiple signaling lamps. Further, there is little
flexibility in modifying the light signal created by a lamp. For
example, changing a stationary lamp into one that rotates or
oscillates would require a substantial modification to the light
bar or light source which may not be physically or economically
possible.
[0007] The present invention generally relates to electrical lamps
and to high brightness light-emitting diode or "LED" technology
which operates to replace gaseous discharge or incandescent lamps
as used with vehicle warning signal light sources.
[0008] In the past, the xenon gaseous discharge lamps have utilized
a sealed compartment, usually a gas tube, which may have been
filled with a particular gas known to have good illuminating
characteristics. One such gas used for this purpose was xenon gas,
which provides illumination when it becomes ionized by the
appropriate voltage application. Xenon gas discharge lamps are used
in the automotive industry to provide high intensity lighting and
are used on emergency vehicles to provide a visible emergency
signal light.
[0009] A xenon gas discharge lamp usually comprises a gas-filled
tube which has an anode element at one end and a cathode element at
the other end, with both ends of the tube being sealed. The anode
and cathode elements each have an electrical conductor attached,
which passes through the sealed gas end of the lamp exterior. An
ionizing trigger wire is typically wound in a helical manner about
the exterior of the glass tube, and this wire is connected to a
high voltage power source typically on the order of 10-12 kilowatts
(kw). The anode and cathode connections are connected to a lower
level voltage source which is sufficient to maintain illumination
of the lamp once the interior gas has been ionized by the high
voltage source. The gas remains ignited until the anode/cathode
voltage is removed; and once the gas ionization is stopped, the
lamp may be ignited again by reapplying the anode/cathode voltage
and reapplying the high voltage to the trigger wire via a voltage
pulse.
[0010] Xenon gas lamps are frequently made from glass tubes which
are formed into semicircular loops to increase the relative light
intensity from the lamp while maintaining a relatively small form
factor. These lamps generate extremely high heat intensity, and
therefore, require positioning of the lamps so as to not cause heat
buildup in nearby components. The glass tube of a xenon lamp is
usually mounted on a light-based pedestal which is sized to fit
into an opening in the light fixture and to hold the heat
generating tube surface in a light fixture compartment which is
separated from other interior compartment surfaces or components.
In a vehicle application, the light and base pedestal are typically
sized to fit through an opening in the light fixture which is about
1 inch in diameter. The light fixture component may have a glass or
plastic cover made from colored material so as to produce a colored
lighting effect when the lamp is ignited. Xenon gas discharge lamps
naturally produce white light, which may be modified to produce a
colored light, of lesser intensity, by placing the xenon lamp in a
fixture having a colored lens. The glass tube of the xenon lamp may
also be painted or otherwise colored to produce a similar result,
although the light illumination from the tube tends to dominate the
coloring; and the light may actually have a colored tint appearance
rather than a solid colored light. The color blue is particularly
hard to produce in this manner.
[0011] Because a preferred use of xenon lamps is in connection with
emergency vehicles, it is particularly important that the lamp be
capable of producing intense coloring associated with emergency
vehicles, i.e., red, blue, amber, green, and clear.
[0012] When xenon lamps are mounted in vehicles, some care must be
taken to reduce the corroding effects of water and various
chemicals, including road salt, which might contaminate the light
fixture. Corrosive effects may destroy the trigger wire and the
wire contacts leading to the anode and cathode. Corrosion is
enhanced because of the high heat generating characteristics of the
lamp which may heat the air inside the lamp fixture when the lamp
is in use, and this heated air may condense when the lamp is off
resulting in moisture buildup inside the fixture. The buildup of
moisture may result in the shorting out of the electrical wires and
degrade the performance of the emission wire, sometimes preventing
proper ionization of the gas within the xenon gas discharge
lamp.
[0013] Another problem with the known warning signal lights is the
use of rotational and/or oscillating mechanisms which are utilized
to impart a rotational or oscillating movement to a light source
for observation during emergency situations. These mechanical
devices are frequently cumbersome and difficult to incorporate and
couple onto various locations about a vehicle due to the size of
the device. These mechanical devices also frequently require a
relatively large power source to impart rotational and/or
oscillating movement for a light source.
[0014] Another problem with the known warning signal lights is the
absence of flexibility for the provision of variable intensity for
the light sources to increase the number of available distinct and
independent visual light effects. In certain situations it may be
desirable to provide variable intensity for a light signal, or a
modulated intensity for a light signal, to provide a unique light
effect to facilitate observation by an individual. In addition, the
provision of a variable or modulated light intensity for a light
signal may further enhance the ability to provide a unique desired
light effect for observation by an individual.
[0015] No known warning light systems utilize a variable or
modulated light intensity to modify a standard lighting effect nor
do they have the design flexibility to easily make those changes.
The warning lights as known are generally limited to a flashing
light signal. Alternatively, other warning signal lights may
provide a sequential illumination of light sources. No warning or
utility light signals are known which simultaneously provide for
modulated and/or variable light intensity for a known type of light
signal to create a unique and desirable type of lighting
effect.
[0016] No warning signal lights are known which provide irregular
or random light intensity to a warning signal light to provide a
desired lighting effect. Also, no warning light signals are known
which provide a regular pattern of variable or modulated light
intensity for a warning signal light to provide a desired type of
lighting effect. It has also not been known to provide a warning
light signal which combines either irregular variable light
intensity or regular modulated light intensity to provide a unique
and desired combination lighting effect.
[0017] It has also not been known to provide alternative colored
LED light sources which may be electrically controlled for the
provision of any desired pattern of light signal such as flashing,
pulsating, oscillating, modulating, variable, rotational,
alternating, strobe, sequential, and/or combination light effects.
In this regard, a need exists to provide a spatially and
electrically efficient LED light source for use on an emergency or
utility vehicle which provides the appearance of rotation, or other
types of light signals.
[0018] In view of the above, there is a need for a warning signal
light that:
[0019] (1) Is capable of producing multiple light signals;
[0020] (2) Produces the appearance of a revolving or oscillating
light signal without reliance upon mechanical components;
[0021] (3) Generates little heat;
[0022] (4) Uses substantially less electrical current;
[0023] (5) Produces significantly reduced amounts of
electromagnetic emissions;
[0024] (6) Is rugged and has a long life cycle;
[0025] (7) Produces a truer light output color without the use of
filters;
[0026] (8) Is positionable at a variety of locations about an
emergency vehicle; and
[0027] (9) Provides variable light intensity to the light
source.
[0028] Other problems associated with the known warning signal
lights relate to the restricted positioning of the signal light on
a vehicle due to the size and shape of the light source. In the
past, light sources due to the relatively large size of light bars
or light sources, were required to be placed on the roof of a
vehicle or at a location which did not interfere with, or obstruct,
an operator's ability to visualize objects while seated in the
interior of the vehicle. Light bars or light sources generally
extended perpendicular to the longitudinal axis of a vehicle and
were therefore more difficult to observe from the sides by an
individual.
[0029] The ease of visualization of an emergency vehicle is a
primary concern to emergency personnel regardless of the location
of the observer. In the past, optimal observation of emergency
lights has occurred when an individual was either directly in front
of, or behind, an emergency vehicle. Observation from the sides, or
at an acute angle relative to the sides, frequently resulted in
reduced observation of emergency lights during an emergency
situation. A need therefore exists to improve the observation of
emergency lights for a vehicle regardless of the location of the
observer. A need also exists to improve the flexibility of
placement of emergency lights upon a vehicle for observation by
individuals during emergency situations.
[0030] A need exists to reduce the size of light sources on an
emergency vehicle and to improve the efficiency of the light
sources particularly with respect to current draw and reduced
aerodynamic drag. In addition, the flexibility for the positioning
of the light sources about a vehicle is required to be enhanced in
order to optimize utility for a warning signal light. In order to
satisfy these and other needs, more spatially efficient light
sources such as LED's are required.
[0031] In the past, illumination of an area to the front or to the
sides of an emergency vehicle during low light conditions has been
problematic. Take-down lights have been utilized by law enforcement
personnel for a number of purposes including, but not necessarily
limited to, enhancing observation of an individual in a vehicle on
a roadway subject to investigation and to hide the location of an
officer, or to block or deter observation of an officer by
individuals during law enforcement activities.
[0032] A need exists for an LED take-down light which has
significant illumination characteristics, is spatially efficient,
has a long useful life, and has reduced current draw requirements
for use on a law enforcement or utility vehicle.
[0033] The alley lights as known also suffer from the deficiencies
as identified for the take-down lights during dark illumination
conditions. Alley lights are used to illuminate areas adjacent to
the sides of a vehicle.
[0034] In the past, the intersection clearing lights have been
predominately formed of halogen, incandescent, and/or gaseous
discharge xenon illumination sources. A need exists for an
intersection clearing light which solves these and other identified
problems.
[0035] A problem has also existed with respect to the use of
emergency lights on unmarked law enforcement vehicles. In the past,
emergency lights for unmarked law enforcement vehicles have
consisted of dome devices which are formed of revolving mechanisms.
These lights are usually withdrawn from a storage position under a
motor vehicle seat for placement upon dashboard of a law
enforcement vehicle. In undercover situations it has been
relatively easy to identify dashboard affixation mechanisms used to
secure these types of dome illumination devices to a dashboard. The
known dome devices are also clumsy, have large current draw
requirements, and are difficult to store in a convenient location
for retrieval in an emergency situation by an individual. A need
therefore exists for an emergency vehicle or utility warning light
which is spatially efficient, easily hidden from view, and is
transportable by an individual for retrieval during an emergency
situation.
[0036] A need also exists for a new emergency vehicle light bar
which is aerodynamic and which provides for both a longitudinal
illumination element and an elevated pod illumination device.
[0037] In the past, emergency personnel, law enforcement officers,
air traffic controllers, and/or pilots have utilized radio
frequencies as a primary means of communication. One draw back
associated with the use of radio frequency communication is the
limited number of radio frequencies available for use within high
density traffic areas where radio saturation may cause an unsafe
condition through delayed communication and response during
transmission of routine information. In addition, a number of
available radio frequencies have been assigned for digital
transmission further limiting the accessability and/or availability
of transmission of routine information. Further, radio frequencies
have generally not been available for certain applications
including communication between motor vehicles and ground sources
related to avionics such as approach lighting and/or taxi location
identification.
[0038] Another problem associated the use of radio frequencies for
communication of routine information is the material intensive
nature of the transmitters and/or receivers. The radio frequency
transmitters and receivers are generally expensive and further
require a large power supply which is a concern for motor vehicle
and/or aircraft applications. A need exists for additional avenues
of relatively short range communication which do not utilize radio
frequency transmissions. In general, cell phones and/or microwave
communication are not viable communication alternatives and/or
options due to the need for instantaneous communication and receipt
of information without the necessity to identify, dial, connect,
and couple to a receiver. A need therefore exists for use of an
alternative communication source and/or carrier of information
which is instantaneous and has high reliability with economical
power consumption and material requirements.
[0039] In the past, attempts have been made to use light as a
communication source normally associated with laser optics. In
general, the use of laser optics as a communication source has
raised a number of considerations related to performance,
durability, and expense. Further, laser optic communication may be
difficult to achieve due to the inflexibility of the lasers for
transmission of both a directional and/or non-directional signal.
The use of laser optics as a communication source has therefore not
proven to be reliable, economical and/or viable for use in motor
vehicle and avionics applications.
[0040] A need exists for a pulsed light signal for communication of
information which is durable, reliable, and economical to an end
user.
[0041] Federal Aviation Administration regulations require an
anti-collision light system for placement on the fuselage of all
aircraft. The rotating features of a dome light and/or flashing
beacon include many of the same problems as earlier described
related to size, durability, performance, current draw parameters,
and ease of maintenance. In general, the light sources utilized
within a rotating dome light or flashing beacon are not durable or
efficient.
[0042] A need exists to replace the known illumination sources for
a rotating dome light and/or flashing beacon as utilized within
aircraft with modern LED light sources.
[0043] Radio frequency transmissions are regulated within the
vicinity of an air field to eliminate and/or minimize risk of
interference with air traffic communications. A need exists for
alternative communication carriers for reduction of radio frequency
communications within the vicinity of an airport. Due to human
factors, in the past it has generally been quite difficult to
instantaneously identify the exact location of aircraft adjacent to
runways during taxiing.
[0044] As known, taxi ways of airports have generally utilized
stationary lights, runway lights, and/or approach lights, which are
not formed of LED technology. Therefore, the brightness,
durability, and economics related to current draw have not been
maximized to provide optimal performance for the known stationary
lights, runway lights, and/or approach lights for an airport.
[0045] In the past it has not been known to use the stationary
lights, runway lights, and/or approach lights as a communication
source for the control of air traffic at an airport. Further, in
the past an aircraft rotating exterior dome illumination source has
not been used to simultaneously function as a communication device
for the transmission and receipt of variable and/or pulsated light
signals as generated from an LED light source. The variable and/or
pulsed light signals may be alternatively described as the
systematic information transfer through encrypted/pulsed light or
acronym SIT-TEL. Further, it has not been know to use a variable
and/or pulsating light signal or SIT-TEL communication, as
generated from an anti-collision light, as an information courier
through the use of LED technology.
[0046] The Federal Aviation Administration requires identification
and collision avoidance systems to be operational at all times at
all airports for regulation of ground and air traffic. No
communication device is know which transmits an encrypted code
within a light carrier for communication of information such as the
proximity to a specific location, and/or for aircraft
identification.
[0047] In the past, air traffic controllers have relied upon VFR or
radar signals in order to identify the position of aircraft
relative to a control tower. Air traffic controllers also utilize
redundant VFR and/or radar systems as backup systems in the event
of an initial systems failure. No economical and/or low power
backup system to the VFR location indicators is generally
available. The high power requirements and equipment expense of VFR
radar systems, and the necessity for redundant backup systems, is
quite costly for an airport. A further backup utilizing a
communication system operating through recognition of pulsed light
signals incorporating low power requirements may be extremely
useful.
[0048] Radio frequency communications are frequently limited, in
that there are a finite number of available radio frequencies for
commercial and/or private use. The available radio frequency
signals are also heavily regulated by the Federal Communications
Commission. In a number of instances, the use of radio frequency
transmissions may cause interference with a localized environment
which in turn may adversely affect adjacent radio frequency
transmitters. A benefit obtained from use of a light source as a
communication carrier is that there are a virtually infinite number
of available wavelengths for a light source. No device has been
previously known which utilize LED technology to generate light
signals used as a carrier of information for the replacement of
radio transmissions, and as particularly used in association with
vehicles and/or aircraft. In addition, no device is known which
utilizes a light signal for transmission to a receiver which may
then trigger audio and/or pre-stored information or convert
information transmitted through the use of pulsed light into an
audio signal.
[0049] A further problem with aircraft rotating illumination domes
and/or flashing beacons is the failure of the illumination domes
and/or flashing beacons to continue operations during emergency
landing situations where the power for the aircraft is terminated.
Due to the large power requirements for the rotating domes and/or
flashing beacons, any power outage within the aircraft normally
terminates the illumination of the rotating dome and/or flashing
beacon. The power requirements for the rotating domes and/or
flashing beacon illumination sources is generally sufficiently
large to prohibit the transportation and use of additional battery
sources for an aircraft during emergency landing situations. A need
therefore exists for an emergency beacon light source which may
continue to operate for an extended period of time, having low
power consumption, which may be operated by a transported battery
within an aircraft. An LED light source associated with the
rotating light and/or exterior beacon therefore significantly
improves the operation of the rotating beacon as an emergency
beacon during emergency landing situations. Further, the low power
requirements of the LED light source enable an exterior rotating
light source and/or flashing beacon to operate for an extended
period of time following a crash landing to signal the
identification of a downed aircraft.
[0050] Needs continue to exist for the use of an LED illumination
source and communication device for use on aircraft support
vehicles, to enhance visual identification and location relative to
an airport; to augment the proximity warning systems for aircraft
and the regulation of air and ground traffic adjacent to an
airport; to enhance the proximity and anti-collision warning light
systems of towers for identification by aircraft; for the provision
of economical and high brightness LED technology light sources for
use in airport runway lighting, airport obstruction lighting, tower
lighting, obstacle lighting, taxi lighting, and for use on aircraft
as rotating domes and/or flashing beacons and/or landing
lights.
[0051] Law enforcement officers in the past have generally been
limited to visualization of a license plate for identification
purposes. Upon visualization of a license plate, an officer may
enter the observed license plate into a data base for
identification of vehicle registration information. In the past,
law enforcement personnel have also utilized optical aids such as
focused optics and/or scopes to assist in the visualization and
identification of license plates on moving vehicles. The optical
and/or focused optic devices are generally expensive and may be
extremely difficult to operate during moving conditions. Vehicles
having the targeted license plates frequently change lanes and/or
bounce upon uneven roadways rendering observation difficult.
[0052] No device is presently known which is inexpensive and which
utilizes LED technology in association with a license plate, which
includes the use of an LED transmitter and light receiver as
coupled to a controller, to receive and transmit a pulsed LED light
signal or SIT-TEL communication as a carrier of information to a
law enforcement vehicle. No device is also known which minimizes
environmental interference and accurately confirms the correct
tagging, observation, and/or interrogation of a license plate by a
law enforcement officer. Further, no backup device is known which
supplements the confirmation system for verification of
identification of a vehicle subject to consideration.
[0053] Another problem with the known law enforcement
identification systems for vehicles is that law enforcement
personnel are frequently required to place themselves within a
certain proximity of a vehicle under observation. Proximity to a
suspect vehicle significantly increases the likelihood of
recognition of the location of the law enforcement personnel. Law
enforcement personnel do not wish to place themselves in close
proximity to a vehicle under consideration. Law enforcement
personnel desire to be unobserved by suspects during law
enforcement investigations and/or activities.
[0054] No communication device is known which may transmit license
plate information such as the plate number, registered owner, make,
model, and/or status of the license plate, to insure that a correct
vehicle has been interrogated during police investigations. A need
also exists to assists law enforcement officers in speed trap
activities to confirm and verify the correct tagging of a target
vehicle with radar and/or laser speed detection devices. No
communication device is currently known which provides flexibility
to select between a focused interrogation specific function versus
a non-directional interrogation function for investigation of
vehicles relative to a law enforcement officer through the use of
LED technology. Further, no communication device is known which may
simultaneously check and compare all license plates within the
proximity of a law enforcement vehicle for a specific status such
as a stolen vehicle identification through a continuous
non-directional sweep of a transmitted LED light signal.
[0055] In the past, buoys have been used in marine applications to
identify channels and hazards such as reefs, bars, rocks, and/or
shallow water conditions. The warning buoys as known have
frequently not included visual warning light signals.
Alternatively, the known warning buoys have included visual warning
light signals which have not been bright or rugged. These warning
buoy light sources have suffered a relatively short life and have
required a relatively large battery source. As such, the warning
light signals used with marine buoys have not been efficient for
signaling marine traffic. No marine buoy is known which utilizes
LED technology to conserve power and to provide a durable and long
useful life light source which may be operated on a relatively
small battery and/or solar power source.
[0056] In addition, no marine buoy is known which incorporates an
LED light source which contains a modulated and/or variable light
controller which may simultaneously transmit a pulsed light signal
or SIT-TEL communication to transmit information obviating the
necessity for radio transmissions.
[0057] Currently each year a significant number of automobiles and
other motor vehicles are involved in accidents with trains at
railroad crossings. Frequently these accidents occur at railroad
crossings in rural areas which are not marked with railroad
crossing gates, warning bells, and/or flashing light signals. The
absence of warning devices is frequently the result of economic
considerations at remote and/or low traffic areas. A need exists
for a warning light signal at remote railroad crossings which may
be easily attached to an existing railroad crossing sign. Further,
a need exists for a low power, battery powered, and/or solar
powered light signal for use at remote railroad crossings which may
be easily activated by an approaching train to warn traffic to
reduce the likelihood of a vehicle/train collision.
[0058] In the past, emergency vehicles have used radio frequency
transmissions to trigger intersection semaphores to switch to a
green light signal to permit uninhibited passage of the emergency
vehicle through the intersection. A problem with the radio
frequency transmissions is the lack of available radio wavelengths,
and the localized radio frequency interference, adjacent to
intersections. In addition, the devices as known frequently have a
large current consumption and are relatively expensive. The
positioning and wiring of OPTICOM receiving and switching devices
upon semaphores is generally elevated above an intersection,
increasing initial construction expenses. The positioning of the
OPTICOM receiving and switching devices, therefore renders
maintenance and/or replacement problematic.
[0059] It has not been known to use light emitting diodes to
provide a light signal to trigger an OPTICOM intersection clearing
light. In addition, it has not been known to improve the useful
life of an OPTICOM device through the use of long life rugged LED
technology which may be operated by a low voltage power source such
as a battery and/or solar power unit.
[0060] No device is known which provides simultaneous communication
to a plurality of independently operated units of soldiers within a
theater of operation which coordinates movement, actions, location
of friendly troops, and/or identifies the location of hostile
soldiers through the use of a pulsed light communication system. In
this regard, no device is known which may have the dual
functionality of a light source such as a flare in combination with
a pulsed SIT-TEL communication system. As is known, radio
communications within a theater of operation are frequently
interrupted or terminated leaving units of troops without direction
as to modified objectives. A need therefore exists for alternative
sources of communication which do not rely upon radio transmissions
for communication of orders and/or other types of critical
information to soldiers engaged in hostilities. In addition,
silence and the secretion of the location of troops within a
theater of operations is frequently critical. Within situations
necessitating silence, the use of radio transmissions is prohibited
leaving soldiers without effective communications. A need therefore
exists for an alternative source of communication for soldiers
which is silent and which does not rely upon radio
transmissions.
GENERAL DESCRIPTION OF THE INVENTION
[0061] According to the invention, there is provided a light
emitting diode (LED) warning signal light and systematic
information transfer through encrypted pulsed light SIT-TEL
communication system which may be depicted in several embodiments.
In general, the warning signal light and SIT-TEL pulsed light
communication system may be formed of a single row, single source,
or an array of light emitting diode light sources configured on a
light support and in electrical communication with a controller and
a power supply, battery, or other electrical source. The warning
signal light and SIT-TEL pulsed light communication system may
provide various light signals, colored light signals, or
combination or patterns of light signals for use in association
with a vehicle or by an individual. These light signals may include
a strobe light, a pulsating light, a revolving light, a flashing
light, a modulated or variable intensity light, an oscillating
light, an alternating light, a pulsating light signal, an encoded
signal, and/or any combination thereof. Additionally, the warning
signal light and SIT-TEL pulsed light communication system may be
capable of displaying symbols, characters, or arrows. Rotating and
oscillating light signals may be produced by sequentially
illuminating columns of LED's on a stationary light support in
combination with the provision of variable light intensity from the
controller. However, the warning signal light and SIT-TEL pulsed
light communication system may also be rotated or oscillated via
mechanical means. The warning signal light and SIT-TEL pulsed light
communication system may also be easily transportable and may be
conveniently connected to a stand such as a tripod for electrical
coupling to a power supply, battery, or other electrical source as
a remote stand-alone signaling or communication device.
[0062] The warning signal light and/or replacement warning signal
light and SIT-TEL pulsed light communication system may be
electrically coupled to a controller used to modulate, pulse, or
encode, the light intensity for the light sources to provide for
various patterns of illumination to create an illusion of rotation
or other type of illusion for the warning signal light without the
use of mechanical devices and/or to transmit and/or receive
messages as desired by an individual.
[0063] A reflective light assembly may also be provided. The
reflective light assembly may rotate about a stationary light
source or the light source may rotate about a stationary reflector.
The reflective assembly may also be positioned at an acute angle of
approximately 45.degree. above a stationary LED panel or solitary
light source, where the reflector may be rotated about a pivot
point and axis to create the appearance of rotation for the light
source.
[0064] The controller is preferably in electrical communication
with the power supply and the LED's to modulate the light intensity
for the LED light sources for provision of a desired type of
warning light effect or encoded SIT-TEL pulsed light communication
signal as desired by an individual. Each individual light support
may be positioned adjacent to, and be in electrical communication
with, another light support through the use of suitable electrical
connections. A plurality of light supports or solitary light
sources may be electrically coupled in either a parallel or series
manner to the controller. The controller is also preferably in
electrical communication with the power supply and the LED's, to
regulate or modulate the light intensity for the LED light sources
for variable illumination of the LED light sources as observed by
an individual. The warning signal lights may encircle an emergency
vehicle. In addition, the light support may be encased within a
waterproof enclosure to prevent moisture or other contamination of
the LED light sources.
[0065] The individual LED's and/or arrays of LED's may be used as
take-down and/or alley lights by law enforcement vehicles to
illuminate dark areas relative to the emergency vehicle. The
take-down light source may be stationary or may be coupled to one
or more rotational mechanisms as desired. The intersection clearing
light may be a particular application of the alley light as mounted
to a motor for oscillation of the light source forwardly and
rearwardly relative to an emergency vehicle. The intersection
clearing mode preferably rotates or oscillates the alley lights
forwardly and rearwardly on each side of a light bar as the
emergency vehicle enters an intersection. The intersection clearing
light mode preferably warns all traffic perpendicular to the
direction of travel of the emergency vehicle as to the presence of
an emergency vehicle within an intersection. When the intersection
clearing light mode is not in operation the alley light or
take-down light may be used to provide illumination at any desired
angle relative to the passenger or drivers areas of an emergency
vehicle.
[0066] A portable pocket LED warning signal light may be provided
having a base and a power adaptor for use in unmarked law
enforcement vehicles. The portable pocket LED warning signal light
may also be connected to, or have, an integral controller for the
provision of a variety of unique light signals as earlier
described. The portable pocket LED may also include one or more
reflective culminators to enhance the performance of the warning or
utility signal light.
[0067] A light bar may also be provided having one or more elevated
pod illumination elements. Each pod illumination element may be
raised with respect to a light bar by one or more supports which
extend upwardly from the base. The pod illumination elements may be
oval or circular in shape. The light bar may also include one or
more longitudinal light elements integral to the base which extend
transversely to the roof of an emergency vehicle.
[0068] The light bar may also include a systematic information
transfer through encrypted/pulsed light (SIT-TEL) system including
a source of LED pulsed light, a receiver of LED pulsed light, and a
controller to reflect and interpret received signals and generate
LED pulsed light signals used in the communication of
information.
[0069] An LED SIT-TEL light signal is provided for replacement of
the exterior rotating dome or flashing beacon of an aircraft. The
LED light support may be rotated and/or stationary as desired. In
addition, the LED light support includes a controller for the
provision of a variety of different types of light signals
including but not necessarily limited to sequential illumination
and/or modulated and/or variable light intensity to simulate the
appearance of a rotating or flashing light beacon. The LED light
signal may include a battery source which may be coupled to a solar
powered energy cell to provide operation and/or functionality when
the main power supply for an aircraft is unavailable. The
controller for the LED light support may generate and/or recognize
SIT-TEL pulsed light signals used to communicate information to a
pilot such as location, clearance, collision warning, obstacle
warning, and/or other aviation information. The SIT-TEL LED light
system may also include a receptor coupled to the controller where
the receptor is constructed and arranged for receipt of pulsed
SIT-TEL LED light signals for conversion to digital information for
transfer to the controller for analysis and interpretation. The
controller may then issue a warning light signal or other
communication signal to the pilot to reflect received information
transmitted via a SIT-TEL pulsed LED light carrier.
[0070] The SIT-TEL LED light system may also be modified for
simultaneous use as an illumination source, receiver, and
transmitter device for use as aviation taxi lights, positioning
lights, runway lights, approach lights, and/or other aviation light
sources. The taxi, runway, approach, anti-collision, positioning
LED lights and/or other aviation lights may simultaneously be
electrically coupled by wire or optically coupled to a control
tower processing center, to provide instantaneous information to
air traffic controllers, representative of the relative position of
an aircraft within an airport. The transmission, receipt and/or
interpretation of a SIT-TEL pulsed LED light signals may
significantly reduce the volume of radio frequency transmissions
proximate to an airport. An air traffic controller within a tower
may easily view a screen which will identify the location and other
information of an aircraft without the necessity for audio
communication via radio frequency transmissions.
[0071] A SIT-TEL LED light system and license plate communication
system may include a license plate having an LED light transmitter
and an LED light receiver/receptor. The LED transmitter and the LED
receptor are each coupled/connected to a controller. The controller
is constructed and arranged for regulating a modulated, variable,
and/or pulsed SIT-TEL light signal to be received and recognized by
a second receptor located within a law enforcement vehicle. A
response SIT-TEL LED pulsed light signal may be generated by the
law enforcement vehicle and received by the first receptor integral
to the license plate. The responsive pulsed SIT-TEL LED light
signal as transmitted from the license plate LED transmitter may
include a series of unique signal packets representative of
information such as the license plate number, vehicle registration
information, and vehicle license plate status. The controller on
the law enforcement vehicle may then process the signal received by
the license plate for comparison to a data base to display
transmitted information on a visible screen for observation by an
officer. The SIT-TEL LED light signal system and license plate
facilitates interrogation of a license plate without necessitating
a police vehicle to close to an observable distance during
investigation activities. The existence of a law enforcement
vehicle may continue to be undetected facilitating law enforcement
activities. The SIT-TEL LED light system and license plate
invention may also function to verify the accuracy of a tagged
vehicle by law enforcement officers during law enforcement
activities.
[0072] An LED light source may be incorporated into a marine buoy
as a replacement for a conventional light source. The LED light
source has improved durability and life expectancy as compared to
conventional light sources. The reduced current draw requirements
permit an LED light source to be used within a marine buoy as
powered by a battery and supplemented by recharging through
coupling to a solar energy cell. In addition, the LED light source
and marine buoy may include a controller and receptor where the
receptor is constructed and arranged to receive a SIT-TEL pulsed
LED signal at a preselected SIT-TEL wavelength. The received
SIT-TEL pulsed light signal may then be translated by the
controller to initiate the transmission of a responsive SIT-TEL
pulsed LED light signal which may include information such as
longitudinal and/or latitude coordinates and/or other information
as may be useful to a ship captain for navigation, and/or a harbor
master for marine traffic control and/or channel marking.
[0073] A SIT-TEL LED light communication system may be incorporated
into a railroad crossing sign for the provision of a warning signal
light indicating the presence of a train. The SIT-TEL LED light
communication system preferably includes a controller and a
receptor adapted to receive a pulsed light signal. A passing train
preferably includes a SIT-TEL LED transmitter and controller to
generate a SIT-TEL pulsed light signal for receipt by the receptor
located on the railroad crossing sign. The generated pulsed light
signal from the train is received by the receptor which in turn is
passed to the controller for translation and activation of a visual
warning light signal and/or audible warning signal at the railroad
crossing. The caboose and/or end of the train may include a second
LED transmitter which generates a second pulsed SIT-TEL LED light
signal. The receipt of the second pulsed SIT-TEL LED light signal
by the receptor is then translated and processed by the controller
to terminate illumination of the LED warning light signal and/or
audible alarm at the railroad crossing. The LED light source
receptor and controller may be powered by a low current power
source such as a battery which may be recharged by coupling to a
solar power cell. A SIT-TEL LED warning light signal may then be
economically provided at remote rural railroad crossings where
traffic volume does not justify inclusion of crossing bars, warning
bells, and/or traditional light sources. The necessity for power
lines coupling a power source to remote railroad crossing warning
signals is thereby eliminated.
[0074] A SIT-TEL LED light source controller and receptor is
preferably coupled adjacent to an intersection semaphore for
activation by law enforcement and/or emergency vehicles during
emergency situations to alter a light signal to permit unobstructed
passage of a law enforcement and/or emergency vehicle during
emergency situations. A law enforcement and/or emergency vehicle
includes a SIT-TEL LED light system and a controller constructed
and arranged to transmit a unique pulsed or encoded SIT-TEL LED
light signal. The OPTICOM receptor upon receipt of the pulsed or
encoded LED light signal, transfers the received signal to the
controller for processing for immediate activation and/or
alteration of the traffic semaphore to permit passage of the law
enforcement and/or emergency vehicle through the intersection. The
LED light source receptor, transmitter, and controller function to
receive and generate a pulsed SIT-TEL LED light signal
significantly enhancing the utility of an intersection clearing
OPTICOM device through the elimination of the necessity for use of
nondurable short life conventional illumination sources while
simultaneously facilitating ease of maintenance and/or replacement.
In addition, the use of an LED light source within the OPTICOM
intersection clearing light reduces electronic current requirements
by the provision of power through the use of a battery which may be
coupled to solar energy power cell.
[0075] The SIT-TEL systematic information through encrypted/pulsed
light system may be incorporated into a flare used within a theater
of operations as a back-up or replacement communication system. The
flare including the SIT-TEL communication system may include a
cylindrical housing having a parachute; a plurality of LED light
sources; a pulsed light photosensitive receiver for detection of
pulsed light signals for reprogramming of communications to be
transmitted as regulated by a controller; and a controller for
regulating pulsed LED light signals which may be used for encrypted
communications. The flare further may include a cavity holding
solid fuel or other types of propellant and one or more
stabilizers. The flare is launched into operation through the use
of a mortar or other device. The controller within the flare may be
reprogrammed prior to launch or following deployment of the
parachute for recognition and generation of pulsed light signals
from the plurality of LED light sources in order to transmit
non-radio communication signals to troops within a theater of
operation. A programming transmitter including a controller and a
pulsed LED light generator may be used to program the controller
within the flare. Alternatively, the controller within the flare
may be coupled to a programming device such as a central processing
unit through the use of a cable. Troops and/or soldiers may each
carry a photosensitive receiver which is constructed and arranged
to recognize pulsed encrypted LED light signals for translation
into a communication which may be observed on a transported
display. The display may be sized for transportation within the
pocket of a soldier. Alternatively, the display may be of
sufficient size for transportation by a designated communication
soldier.

receiver/transmitter of SIT-TEL LED pulsed light signals for use by
troops.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0244] A warning signal light according to the principles of the
invention is indicated generally herein as numeral 10. FIGS. 1 and
2 depict light bar 70 mounted to an emergency vehicle 104. Light
bar 70, includes base 72, mounting means 74, cover 82, and warning
signal lights 10. Also included in light bar 70, may be gyrators
90, which may be used to impart motion to warning signal lights
10.
[0245] Referring to FIGS. 3 and 9, warning signal light 10,
comprises light support 12, LED light sources 30, controller 50
(shown in FIG. 11), and connecting portion 40, for attaching the
warning signal light 10, to light bar 70, or gyrator 90. The
warning signal light 10, operates to create a warning signal for
use by an emergency vehicle 104, by selectively activating light
sources 30 or by selectively activating combinations and/or
patterns of light sources 30 by using controller 50. Alternatively,
warning signal light 10, may be formed of one or more solitary LED
light sources 30.
[0246] Light sources 30, are preferably light emitting diodes
(LED's) and are generally arranged in aligned columns 32, and/or
rows 34, as shown in FIGS. 7 and 9. Each of the light emitting
diodes (LED's) may have shoulder portion 38, adjacent LED support
12, and dome 36. LED's 30, are situated to be in electric
communication with controller 50, and a power supply, a battery, or
power source. The use of light emitting diodes (LED's) to replace
traditional halogen, incandescent, or gaseous discharge xenon lamps
reduces heat generation, current draw, and electromagnetic
emissions, while increasing lamp life and producing a more true
output light color.
[0247] The controller 50 is used to selectively activate portions
or entire columns 32, rows 34, or individual LED's 30, to
illuminate any number of a plurality of visually distinct types of
warning light signals at any moment; to illuminate more than one of
a plurality of visually distinct types of warning light signals
simultaneously at any moment; to illuminate one of a plurality of
combinations or patterns of visually distinct warning light signals
at any moment, or over any desired period of time, or to illuminate
more than one of a plurality of combinations or patterns of
visually distinct warning light signals over any desired period of
time. The plurality of visually distinct warning light signals may
include, but are not necessarily limited to, a strobe light signal,
a pulsating light signal, an alternating light, a modulated light
signal, a variable light signal, a flashing light signal, the
illusion of a rotating or an oscillating light signal, a reverse
character message, a sequential light signal, a random light
signal, or images such as arrows. The controller 50 may also
incorporate into any selected warning light signal variable or
modulated light intensity to facilitate the provision of a desired
unique lighting effect. For example, the controller 50 may
illuminate one or more LED light sources 30 to establish a single
warning light signal at a given moment. Alternatively, the
controller 50 may illuminate one or more light emitting diode light
sources 30 to provide two or more warning light signals at any
given moment. Further, the controller 50 may simultaneously,
consecutively, or alternatively, illuminate one or more LED light
sources 30 to establish any desired combination or pattern of
illuminated visually distinct warning light signals at any given
moment or over a desired period of time. The combination and/or
pattern of visually distinct warning light signals may be random,
intermittent, or may be regularly cycled. The illumination of one
or more patterns or combinations of warning light signals
facilitates the continued observation by an individual.
Occasionally, the concentration or attention of an individual is
diminished when exposed to a repetitive or to a monotonous light
signal. The desired purpose for illumination of a warning light
signal is thereby reduced. The provision of a pattern, combination,
and/or random illumination of visually distinct warning light
signals maximizes the concentration or attention to be received
from an individual observing a warning light signal. The purpose of
the warning light signal is thereby promoted.
[0248] FIGS. 11A, 11B, and 11C show an embodiment of controller 50
capable of selectively activating columns 32, rows 34, individual
or combinations of individual LED's 30. Controller 50 generally
comprises microprocessor 52 and circuitry 53 and is contained
within, attached to, or an element of, LED support 12. It is
envisioned that controller 50 may be programmed by an external
controller 55 and powered through cable R.
[0249] In one embodiment, controller 50 generally comprises circuit
board or LED mounting surface having microprocessor 52 attached to
a low voltage power supply, battery, or electrical source 56.
Microprocessor 52 is configured through circuitry 53 to selectively
activate columns 32, rows 34, or one or more individual LED's 30.
Transistors Q9 and Q10 are in electronic communication with
microprocessor 52, power supply, battery, or electrical source 56,
and their respective columns 32.9 and 32.10 of LED's 30. Columns 32
of LED's 30 are connected to transistors Q1-Q8, which are in turn
connected to microprocessor 52 through resistors R1-R8.
Microprocessor 52 is capable of selectively activating transistors
Q1-Q8 to allow current flowing through transistors Q9 and Q-10 to
activate the selected column 32 of LED's 30. This circuit is
capable of producing any one or more of the different types of
light signals as earlier identified.
[0250] In one embodiment, a rotating or oscillating light signal
may be established by the sequential illumination of entire columns
32 of LED's 30 by turning a desired number of columns on and then
sequentially illuminating one additional column 32 while turning
another column 32 off. Alternatively, the rotating or oscillating
warning light signal may be created by selectively activating
columns 32 of LED's 30. The following algorithm may be used to
provide a counterclockwise revolving light signal (FIG. 9): [0251]

step 1).
[0271] A clockwise revolving light signal may be created by
performing steps 1-19 in descending order then repeating the steps.
An oscillating light signal may be created by performing: (a) steps
7 through 16 in ascending order; (b) steps 7 through 16 in
descending order; and (c) repeating (a) and (b).
[0272] A second embodiment of controller 50 provides a means for
activating LED's 30 individually to allow for greater flexibility
in the type of warning light signal created. This embodiment of the
invention is capable of displaying information in different colors
or patterns. Depending on the size of the display, it may be
necessary to scroll the symbols or characters across the display to
accommodate for a larger visual appearance. It is envisioned that
the mirror image of patterns, symbols, or characters could be
displayed making the message easily readable by drivers viewing the
signal in a rear view mirror. It is also envisioned that the
warning light signal could display arrows indicating a direction a
vehicle is to travel or other images as shown in FIG. 2. In
addition, combinations of warning signal lights, direction arrows,
and other information carrying signals or images, may be displayed
simultaneously by the invention.
[0273] LED support 12 is envisioned to have several embodiments.
One embodiment, shown in FIG. 9, consists of a panel 14 having
front 16, back 18, top 20, bottom 22 and sides 24. LED's 30 are
arranged on front 16, with domes 36 extending therefrom, in columns
32 and rows 34. LED's 30 are in electric communication with
controller 50 which may be contained or sealed within LED support
12 to provide protection from the elements.
[0274] Another embodiment of warning signal light 10 is depicted in
FIG. 10. Here, the backs 18 of two panels 14 are attached together
to allow for a light signal to be produced on two sides. The two
panels 14 form LED support 12. Alternatively, it is envisioned that
a single panel 14 having LED's arranged about front 16 and back 18
could be used as well.
[0275] FIGS. 6 and 8 show further embodiments of warning signal
light 10. In FIG. 8, panels 14 are used to form an LED support 12
having four sides and generally shaped as squared. FIG. 6 shows
panels 14 connected to form an LED support 12 having three sides
and generally triangular in shape. In both embodiments, LED's 30
are arranged about the fronts 16 of the panels 14. It is further
envisioned that panels 14 may be integral to each other.
[0276] Yet another embodiment of warning signal light 10, consists
of a flexible panel 14 and controller 50 to allow LED support 12 to
be formed into various shapes. FIG. 5 shows LED support 12 formed
into a cylinder. Further variations include the use of flexible
panels 14 to form other shapes such as semicircles (FIG. 12) or to
simply conform to a surface of an emergency vehicle (FIGS. 13 and
14). This embodiment is particularly useful for undercover vehicles
which generally position the warning signal lights inside the
vehicle. For example, panel 14 could be attached to the front,
rear, or side window of an undercover police vehicle.
[0277] Numerous other shapes could be formed from panels 14
including those formed from combinations of flat, curved, and
flexible panels.
[0278] In each of the embodiments discussed above, the array of
LED's 30 may be formed of the same or differently colored LED's.
Generally, each column 32 or row 34 may consist of a series of
differently colored LED's. Controller 50 may be configured to
select the color of the LED's to be illuminated forming the light
signal. Accordingly, the user may select a blue, red, white,
yellow, green, or amber color or any combination thereof to be used
as the color of light signal. Alternatively, the warning signal 10
may be formed of individual LED's 30 which may be selectively
illuminated for generation of a particular type of light
signal.
[0279] It is also envisioned that the controller 50 may control
warning signal lights 10 having multiple sides (FIGS. 5, 6, 8, and
10) such that each side is capable of producing warning light
signals or combinations of warning light signals that are
independent and/or different from those produced upon the other
sides. For example, the squared shape warning signal light shown in
FIG. 8 may produce or simulate a red revolving light on first side
15.1, while second side 15.2 is simultaneously producing a blue
oscillating light, while third side 15.3 is producing or simulating
a stationary white light, and while fourth side 15.4 is producing a
white strobe light.
[0280] Another embodiment of warning signal light 10 is depicted in
FIGS. 1 and 2 as light bar 70 which extends from driver side 100 to
passenger side 102 of emergency vehicle 104. Cover 82 protects
light bar 70 from the elements. Each side of light bar 70 may have
LED's 30 to produce or simulate warning light signals on each side
of emergency vehicle 104. Furthermore, controller 50 may be used to
create multiple warning light signals on each side of light bar 70.
For example, controller 50 may create a simulated revolving blue
light positioned at front passenger side 102 of light bar 70,
oscillating white lights positioned at front driver side 100, and
yellow arrows there between. Additional or alternative warning
light signals may be produced out the back 18 and sides of light
bar 70. It is further envisioned that light bar 70 may consist of a
single light source, a single row of light sources or a large array
of LED's 30 across each side (not shown). This embodiment provides
the largest display and, therefore, is best suited to display
desired combinations of warning lights and images. It should be
noted that the identified types of warning light signals,
combinations and/or patterns of warning light signals, may also be
reproduced through the illumination of a single row of LED light
sources 30 and that the type of patterns previously identified are
not intended to be exclusive in that an infinite variety of
combinations and/or patterns are available for generation by
controller 50.
[0281] Mechanical rotation and oscillation of warning signal lights
10 about axis "A" is possible by way of attachment to gyrator 90
depicted in FIG. 3. Gyrator 90 mounted to light bar 70, generally
comprises electric motors 96 having cables 97. Gyrator 90 is
configured to receive connecting portion 40 of warning signal light
10. Cable 97 is preferably connected to a power supply and either
an external controller 55 or controller 50.
[0282] Gyrator 90 may be capable of rotating or oscillating warning
signal light 10 about a single or dual axis of rotation "A". FIG. 3
shows gyrator 90 configured to rotate or oscillate warning signal
light 10 about a vertical axis "A" by way of motor 96.1 and
oscillate warning signal light 10 about a horizontal axis "A" by
way of motor 96.2. Rotation or oscillation of warning signal light
10 about vertical axis "A" is accomplished through direct
attachment of connecting portion to motor 96.1. Oscillation of
warning signal light 10 about horizontal axis "A" is accomplished
by attaching swivel arm 99 to bracket 99.1 and post 99.2 which is
mounted to motor 96.2.
[0283] Alternative methods for imparting rotation or oscillation
motion to warning signal light 10 may be accomplished through the
use of electric motors, toothed gears, and worm gears. In addition,
maintaining electrical communication between a power supply and an
external controller 55 with a revolving or oscillating warning
signal light 10 may be accomplished using brushes or other means
without sacrificing the operation of the warning signal light
10.
[0284] In another embodiment as depicted in FIGS. 13 and 14,
emergency vehicle 104 may include a front or rear windshield 106.
The front or rear windshield 106 is generally angularly offset with
respect to the vehicle at an approximate angle of 45 degrees. In
this embodiment, the mounting of a panel 14 of light sources 30 in
flush contact with the interior of a front or rear windshield 106
may occur through the use of angular offsets 108 for the light
sources 30 such that light is transmitted from the light sources 30
at a horizontal visual line (V) which is substantially parallel to
the plane of a vehicle and not at an approximate angle of 45
degrees upward, which corresponds to the angle for the front or
rear windshield 106.
[0285] In this embodiment, the ease of visualization of a generated
light signal is significantly enhanced by the downward angular
offsets 108 which position the light sources 30 along parallel
visual lines of sight (V). LED supports 12 or panels 14 may then be
positioned in any desired location within the interior of a vehicle
in flush contact or proximate to the front or rear windshield 106.
A suitable cable 97 is required to provide electrical power for
illumination of the light sources 30. It should be noted that the
angle of incidence for the angular offsets 108 may vary
considerably dependent upon the make or model for the vehicle to
include the warning signal lights 10.
[0286] The warning signal light 10 may be used upon an automobile,
motorcycle, snowmobile, personal water craft, boat, truck, fire
vehicle, helicopter, and/or any other type of vehicle receptive to
the use of warning signal lights 10. The LED support 12 or panel 14
may be mounted to the interior top dashboard of a vehicle proximate
to the front windshield 106 or to the interior top rear dashboard
proximate to the rear windshield 106 of a vehicle.
[0287] Mounting of a light support 12 or panel 14 to either the
front or rear dashboards may minimize the necessity for inclusion
of angular offset 108 for the light sources 30. The LED supports 12
or panels 14 may be releasably affixed to the interior of the front
or rear windshields 106 via the use of suction cups, hook-and-loop
fabric material such as Velcro.RTM., and/or any other releasable
affixation mechanism. An individual may then adjust and reposition
the location of the light support 12 or panels 14 anywhere within
the interior of a vehicle as desired for maximization of
visualization of the warning signal lights 10.
[0288] In another alternative embodiment as depicted in FIG. 15,
warning signal light 10 may function as a remote, revolving, or
stationary beacon. In this embodiment, LED support 12 or panel 14
is preferably releasably connected to a transportable support 120
via the use of a bracket. The transportable support 120 may be a
tripod having telescoping legs or may be any other type of support.
In this embodiment, LED light support 12 or panel 14 is
electrically connected to an elongate electrical extension cable 97
which may include any desired adapter for electrical connection to
a power source which may be a vehicle. The remote light support 12
or panel 14 may also include plug-in adapters for electrical
connection to any desired electrical power source other than a
vehicle as is available. Alternatively, the LED light support 12 or
panel 14 may be electrically connected to a battery or rechargeable
battery to provide power to the LED's 30.
[0289] The transportable support 120 may also include gyrator 90 as
earlier described to provide rotational or oscillatory motion for
warning signal light 10. A controller 50 having a microprocessor 52
may also be integral to, or in electrical communication with, LED's
30 for the provision of multi-colored lights, one or more of the
warning light signals or patterns or combinations of warning light
signals as earlier described. In this embodiment, the warning
signal light 10 may be physically separated from an emergency
vehicle 104 any desired distance to facilitate or enhance the
safety of a potentially dangerous situation necessitating the use
of a warning light. Further, a series of remote warning signal
lights 10 may be electrically coupled to each other for any desired
distance to again facilitate the environmental safety of an
emergency location.
[0290] FIG. 16 shows a perspective view of a xenon lamp 1. Xenon
lamp 1 has a base pedestal 2 which is typically formed of rubber,
plastic, or other insulating material. Base pedestal 2 has a top
surface 3 which may support a glass tube 4 which may have a looped
curve such that an anode end and a cathode end are each supported
on a top surface. The anode and cathode ends may be sealed and
respective electrical conductors 5 and 6 may pass through the
sealed ends and through the top surface 3. A trigger wire 7 may be
helically wound about the exterior surface of the glass tube 4 and
the ends of the trigger wire 7 may be passed through the top
surface 3 of the base pedestal 2 to form a third conductor on the
underside of the base pedestal 2.
[0291] Base pedestal 2 may have an upper cylinder portion 8
extending from a lower shoulder all of which may extend above the
top surface 3. The upper cylindrical portion 8 may include an upper
shoulder 9. A glass dome (not shown) may be sized to fit over the
xenon lamp 1 and glass tube 4 for resting on the upper shoulder 9.
The glass dome may be formed of a transparent or silicate glass
material capable of withstanding heat stress. The outer diameter of
the glass dome is typically about one inch which is sized to fit
through the conventional opening in a typical vehicle lamp fixture.
The exterior glass dome surface typically has a much lower
temperature during operation than the exterior surface of the glass
tube 4 forming a part of the xenon lamp 1. The temperature drop
between the glass tube 4 and the glass dome facilitates the use of
coloring of the dome to provide a colored lamp by virtue of the
xenon light intensity passing through the colored dome acting as a
filter.
[0292] The xenon lamp 1 is preferably aligned for insertion into a
conventional opening 248 of a light reflector 260 (FIGS. 20 and
21). The light receptacle opening 248 in the light reflector 260 is
typically about one inch in diameter; and the glass dome and base
pedestal 2 are sized to fit within the light receptacle opening
248. The xenon lamp 1 in its final construction may include a cover
plate (not shown) affixed over the bottom opening of the base
pedestal 2 for affixation to a light reflector 260 via the use of
screws which pass through the screw apertures 9.1. The anode,
cathode, and trigger wire 7 traverse the base pedestal 2 and may
include a plug 9.2 which is adapted for engagement to a
controller/power supply for a motor vehicle.
[0293] The light reflector 260 may be a conventional light
reflector of the type found in vehicles having a clear plastic or
glass lens cover. The glass or lens cover may be fitted over the
front edge of the reflector 260 in a manner which is conventional
for vehicle lamps. The light reflector 260 may have a parabolic or
other shape. The light reflector 260 may be mounted to a motor for
rotation about a vertical axis. In this embodiment the light
source/replacement lamp 200 may be integrally connected or affixed
to the reflector 260 for simultaneous rotation about the vertical
axis during use of the motor. (FIGS. 17, 20, 21, 22) Alternatively,
the light source/replacement lamp 200 may be fixed proximate to the
vertical axis where the light reflector 260 is rotated around the
stationary replacement lamp 200 to provide for the visual
appearance of a rotational light source.
[0294] In operation, the LED replacement lamp 200 may be
constructed as a replacement part for a conventional incandescent
or xenon gaseous discharge lamp. The standard mounting base 204 and
LED support assembly 212 may be sized to readily fit into the same
light opening as an incandescent lamp would require, although it is
apparent the electrical driving circuit for the LED replacement
lamp 200 may require modifications to accommodate the LED operating
principles.
[0295] LED warning signal lamp 200 may be used in a variety of
locations about a vehicle. The use of the LED warning signal lamps
200 are not necessarily limited to positioning adjacent to the head
lamp or headlight, tail light, or turn signal illumination devices.
The LED warning signal lamp 200 may be used as a rotational,
pulsating, or oscillating reflector light within the interior,
adjacent to a front, rear, and/or side window of a vehicle.
[0296] It is also envisioned that the controller 50 may control
warning signal lights 200 independently of one another such that
each warning signal lamp 200 is capable of producing warning light
signals which are independent and/or different from those produced
at another location about an emergency vehicle 104. For example, a
front left location may produce a red colored light while
simultaneously a front right location may produce an amber colored
light and a right rear location may produce a green colored light
and a left rear location may produce a blue colored light. The
controller 50 may then alternate the color of the light illuminated
from the warning signal lamp 200 in each area. Alternatively, the
controller 50 may sequentially activate warning signal lamps 200
positioned about an emergency vehicle 104 to simultaneously produce
a desired color or alternating sequence of colors. The controller
50 may simultaneously illuminate all LED warning signal lamps 200
to produce a flashing or strobe light which may be particularly
useful in certain emergency situations. The controller 50 may also
selectively illuminate individual LED warning signal lamps 200 in
any desired color, pattern, and/or combination.
[0297] Referring to FIG. 17 in detail, an LED replacement lamp 200
is depicted.
[0298] In this embodiment the LED replacement lamp 200 includes a
standard mounting base 204 which includes a top surface 206.
Extending upwardly from the top surface 206 is an upper cylindrical
portion 208 which includes an upper shoulder 210. Extending
upwardly from the upper shoulder 210 is an LED support assembly 212
which includes one or more LED lamp modules 213. The LED lamp
modules 213 may be of the same or different colors. A wire 202 is
in electrical communication with the plurality of LED lamp modules
213 to provide for electrical communication with the controller 50
to individually activate or illuminate LED lamp modules 213. A
plug-in connector 40 may be coupled to the wire 202 for engagement
to the controller 50 and/or power source of an emergency vehicle
104.
[0299] The LED replacement lamp 200 is adapted to be positioned in
a one inch light receptacle opening 248 (approximate size) which
has been previously placed through the backside of a reflector
assembly 260. The LED replacement lamp 200 is used to replace a
xenon gaseous discharge lamp or incandescent lamp as previously
mounted to a base which is inserted into opening 248 in a reflector
assembly 260. Illumination of one or more individual LED lamp
modules 213, as mounted in the reflector assembly 260, enables the
reflector assembly/lens to take on the appearance of a warning
signal or emergency signaling lamp.
[0300] Referring to FIG. 18, an incandescent lamp or quartz halogen
H-2 lamp is depicted and in general is indicated by the numeral
220. The incandescent lamp assembly 220 is formed of a standard
mounting base 222. A vertical post 224 extends upwardly from the
standard mounting base 222. The incandescent light bulb 226 is
mounted in the vertical post 224. The vertical post 224 may extend
below the standard mounting base 222 to provide for electrical
coupling with a wire 228 which includes a standard pin connector
230. The standard pin connector 230 is adapted for electrical
communication to a power supply and/or controller 50 for activation
of the incandescent lamp assembly 220. The incandescent lamp
assembly 220 may be stationary or mounted in a rotational light
reflector 260. The light bulb 226 may be a halogen H-2, 55 watt,
lamp.
[0301] As depicted in FIG. 19, LED replacement lamp 200 is adapted
to replace the incandescent lamp assembly 220 in a stationary or
rotational light reflector 260. The LED replacement lamp 200 as
depicted in FIG. 19 includes a standard mounting base 234 and a
vertical post 236. The vertical post 236 may extend upwardly from
the standard mounting base 234 and may alternatively extend below
the standard mounting base 234. An LED mounting area 238 may be
integral or affixed to the upper section of the vertical post 236.
The LED mounting area 238 includes a plurality of individual LED
module lamps 240 which may be illuminated individually,
sequentially, or in combination with other light sources.
[0302] The individual LED module lamps 240 are in electrical
communication with a wire 242 which includes an integral standard
wire connector 244. The wire connector 244 is adapted to be plugged
into a controller 50 or power supply. Communication is thereby
provided for selective illumination of the individual LED module
lamps 240. A group of individual LED module lamps 240 may be
mounted in the LED mounting area 238. The LED replacement lamp 200
is adapted to replace the incandescent lamp assembly 220 or a xenon
gaseous discharge lamp assembly base of FIG. 16 or 18. The purpose
of the LED replacement lamp assembly 200 is to replace existing
xenon gaseous discharge and incandescent lamps with new LED
technology while simultaneously utilizing existing standard bases
in a standard lamp enclosure. For example, an individual may choose
to replace a halogen "H-2" 55 watt lamp with an "LED-2" lamp in an
existing rotating light fixture with no other structural
modifications, yet achieving the advantages of less power
consumption, greater reliability, easier installation, less RF
emissions (which reduces interference with radio or electronic
equipment), cooler operating temperatures, simplified circuitry,
longer life, greater durability and duty capability, and
simultaneously providing pure and easier-to-see color light
output.
[0303] As depicted in FIG. 20, a rotational light reflector 246 is
disclosed. The rotational light fixture 246 includes a reflector
assembly 260 having a standard opening 248. The incandescent light
assembly 220 is positioned in the standard opening 248 for
extension of the vertical post 224 outwardly from the reflector
assembly 260 for positioning of the light bulb 226 in a desired
location. Light emitted from the standard halogen light bulb 226
reflects off the parabolic-shaped reflector assembly 260 for
transmission of light in a direction as indicated by arrows AA for
visualization by individuals. Reflector assembly 260 and light
source 226 may be rotated via the use of gears 250 which are driven
by electrical motors not shown. In this manner, the rotational
light fixture 246 including the reflector assembly 260 may be
rotated at any desired velocity as preferred by an individual.
[0304] As may be seen in FIG. 21, a rear or back view of the
rotational light fixture 246 is provided. As may be seen in FIG.
21, the light source is positioned in the standard opening 248. The
wire 228 is in electrical communication with the light source and
is connected via the standard pin connector 230 to a power
source.
[0305] As depicted in FIG. 22, an alternative rotational light
fixture 252 is depicted. Rotational light fixture 252 includes a
reflector assembly 260 which may be parabolic in shape for the
transmission of light along a common axis as depicted by arrows BB
for visualization by an individual. In this embodiment, the
individual LED module lamps 240 may be positioned to the front of
the reflector assembly 260 through the use of a frame 254. The
frame 254 may be integral or connected to a gear 250. The gear 250
may be driven by a motor for rotation of the light fixture 252. The
individual LED module lamps 240 are in electrical communication
with a power source not shown.
[0306] The rotational light fixture 252 may also be adapted for the
provision of an oscillating or pulsating warning light signal.
[0307] An alternative replacement LED lamp 200 is depicted in FIGS.
23-25. In this embodiment the LED replacement lamp 200 includes a
standard mounting base 270. The standard mounting base 270 also
includes a plurality of teeth 272. The teeth 272 are adapted for
mating coupling with gears integral to a motor and/or reflector
260, or rotational light fixture 246 to facilitate rotation and/or
oscillation of the replacement LED lamp 200. The standard mounting
base 270 also includes a top surface 274 opposite to the teeth
272.
[0308] An upper cylinder portion 276 is adjacent to the top surface
274. The upper cylinder portion 276 includes an upper shoulder 278.
Extending upwardly from the upper shoulder 278 is a circuit board,
LED mounting surface, or support 280 which includes one or more LED
illumination sources 282. The LED illumination sources 282 may be
of the same or different colors. A wire 284 is in electrical
communication with the LED illumination sources 282 to provide for
communication and contact with the controller 50 for combination
and/or individual illumination of the LED illumination sources 282.
A standard plug-in connector may be integral to the wire 284 to
facilitate coupling engagement to the controller 50 and/or power
source for a vehicle 104.
[0309] The circuit board or LED mounting surface 280 is adapted to
include a first side 286 and an opposite side 288. A plurality of
LED illumination sources 282 are disposed on both the first side
286 and the opposite side 288 of the replacement lamp 200.
[0310] A glass dome or protector 290 is adapted for positioning
over the circuit board or LED mounting surface 280 for sealing
engagement to the top surface 274 of the standard mounting base
270. The glass dome 290 may be formed of transparent plastic
material or a transparent or silicate glass material capable of
withstanding heat stress. The glass dome 290 protects the circuit
board or LED mounting surface 280 and the LED illumination sources
282 from contamination and from exposure to moisture during use of
the replacement lamp 200. In this regard, the sealing lip 292 of
the glass dome 290 is securely affixed to the top surface 274 to
effectuate sealing engagement therebetween. The outer diameter of
the glass dome 290 is about one inch which is sized to fit within
the conventional opening 248 in a typical lamp fixture or reflector
assembly 260.
[0311] The replacement lamp 200 depicted in FIGS. 23, 24, and 25 is
also adapted to be positioned in a one inch light receptacle
opening 248 which has been placed into a reflector assembly 260.
Illumination of one or more individual LED illumination sources 282
as disposed on the circuit board or LED mounting surface 280
enables the replacement lamp 200 to take on the appearance of a
warning signal or emergency signaling lamp.
[0312] The replacement lamp as depicted in FIGS. 23, 24, and 25 may
alternatively permit the circuit board 280 to extend below the
upper shoulder 278 to facilitate affixation and positioning
relative to the standard mounting base 270.
[0313] The controller 50 may regulate the illumination of the LED
light sources 282 individually, or in combination, to provide a
desired warning lighting effect for the replacement lamp 200. Also,
the controller 50 may illuminate the LED light sources 282
individually, or in combination, independently with respect to the
first side 286 and the opposite side 288 to provide different
warning light effects to be observed by an individual dependant
upon the location of the person relative to the light source. The
controller 50 may also simultaneously or independently regulate the
light intensity for the LED illumination sources 282 to provide for
a pulsating, modulated or variable light intensity for observation
by an individual.
[0314] In an alternative embodiment, the LED warning signal lamps
10 or LED replacement lamps 200 may be electrically coupled to a
controller 50 which in turn is used to provide a modulated light
intensity for the light source. A modulated light intensity enables
the provision of various light output or patterns of illumination
for creation of a plurality of visually distinct warning light
signals without the use of mechanical devices. In these
embodiments, the controller 50 illuminates selected light sources
282 and the controller 50 may also regulate and/or modulate the
duty cycle for the light sources 282, thereby varying the intensity
of the observed light. In addition, the controller 50 may modulate
the duty cycle for the LED warning signal lamps 10 or LED
replacement lamps 200 in accordance with a sine wave pattern having
a range of 0 to full intensity. At the instant of full intensity,
the controller 50 may also signal or regulate an illumination burst
for observation by an individual. The controller 50 operating to
regulate and/or modulate the light intensity for the warning signal
lamps 10 or LED replacement lamps 200 in conjunction with
illumination and non-illumination of selected light source 282 may
establish one or more of the types of light signals identified
herein.
[0315] The controller 50 may also regulate the modulated light
intensity for the provision of a unique variable intensity warning
light signal. The unique variable intensity light source is not
required to cycle through a zero intensity phase. It is anticipated
that in this embodiment that the range of intensity will cycle from
any desired level between zero to full intensity. A range of light
intensity may be provided between thirty percent to full intensity
and back to thirty percent as regulated by the controller 50. An
irregular pattern of variable power intensity may be utilized to
create a desired type of warning light effect. In addition, the
controller 50 may also sequentially illuminate adjacent columns 32
to provide a unique variable rotational, alternating, oscillating,
pulsating, flashing, and/or combination variable rotational,
alternating, pulsating, oscillating, or flashing visual warning
light effects. A pulsating warning light signal may therefore be
provided through the use of modulated light intensity to create a
varying visual illumination or intensity effect. The controller 50
may also modulate the light intensity for any combination of light
sources 30 or 282 to provide a distinctive or unique type of
warning light signal.
[0316] The use of a controller 50 to provide a modulated light
intensity for a light source may be implemented in conjunction with
replacement lamps 200, flexible circuit boards having LED light
sources 30, paneled circuit boards or LED mounting surfaces having
LED light sources 30, light bars 70 having LED light sources 30, a
cylindrical, square, rectangular, or triangular-shaped circuit
boards having LED light sources 30 and/or any other type or shape
of LED light sources including but not limited to the embodiments
described herein.
[0317] Further, the controller 50 may be utilized to simultaneously
provide modulated or variable light intensity to different and/or
independent sections, areas, and/or sectors 326 of a light source
(FIG. 35). Also, the controller 50 may be utilized to
simultaneously provide modulated or variable light intensity to
different and/or independent sectors, areas, and/or sections 326 of
the forward facing side or rearward facing side of a light support
or light bar 70 for the provision of different warning light
signals or a different warning light effects on each side. In this
embodiment it is not required that the forward facing and rearward
facing sides of the light support or light bar 70 emit the
identical visual patterns of illuminated light sources 30. The
controller 50 may regulate and modulate the variable light
intensity of any desired sector 326 of the forward facing side
independently from the rearward facing side of the light support or
light bar 70. An infinite variety of patterns and/or combinations
of patterns of warning light signals may be provided for the
forward facing side and the rearward facing side of the light
support or light bar 70.
[0318] The modulated light intensity may be regulated by the
controller 50 to create a unique warning light signal within a
single sector 326 or in conjunction with multiple separated or
adjacent sectors 326 of light bar 70 or light support for the
provision of any desired composite emergency warning light signal.
All individual LED light sources 30 within a light bar 70 or light
support may be simultaneously exposed to incrementally increased
modulated light intensity to provide for an incremental increase in
illumination. An illumination burst may be provided at any time
during the incremental increase of illumination. The modulation of
the light intensity in conjunction with the incremental increase in
illumination of all LED light sources 30 within light bar 70 or
light support may provide the appearance of rotation of a warning
light signal when observed by an individual. The illumination of
the individual light sources 30 may then be incrementally
decreased. The light intensity is not required to be regularly
incrementally increased or decreased or terminated. It is
anticipated that any pulsating and/or modulated variable light
intensity may be provided by the controller 50 to the LED light
sources 30.
[0319] All individual LED light sources 30 within a light bar 70 or
light support are not required to be simultaneously and
incrementally illuminated to provide for the appearance of
rotation. For example, a light bar 70 or light support may be
separated into one or more distinct segments 326 which are formed
of one or more columns 32 of LED light sources 30. A particular
segment 326 may be selected as a central illumination band which
may receive the greatest exposure to the modulated or variable
light intensity and, therefore, provide the brightest observable
light signal. (FIG. 35) An adjacent segment 332 may be disposed on
each side of the central illumination band 330 which in turn may
receive modulated or variable light intensity of reduced magnitude
as compared to the central illumination band 330. A pair of removed
segments 333 may be adjacent and exterior to the segments 332, and
in turn, may receive exposure to a modulated light intensity of
reduced magnitude as compared to segments 332. The number of
desired segments may naturally vary. The controller 50 may thereby
regulate the light intensity to provide a modulated or variable
light signal for each individual segment 330, 332, or 333 (FIG. 35)
to provide for a unique warning light effect for the light bar 70
or light support.
[0320] The provision of a modulated light intensity to the light
bar 70 or light support may also be coupled with, or in combination
to, the sequential illumination of columns 32 as earlier described.
In this situation, the warning light signal may initially be dim or
off as the individual columns 32 are sequentially illuminated and
extinguished for illumination of an adjacent column or columns 32.
The light intensity for the illuminated column or columns 32 may
simultaneously be incrementally increased for a combination unique
rotational and pulsating modulated or variable warning light
signal.
[0321] Each individual LED light source 30 preferably provides an
energy light output of between 20 and 200 or more lumens. Each
support 12 may be controlled as part of an overall warning light
signal or pattern where individual supports 12 may be illuminated
to provide a desired type or combination light signal in addition
to the provision of a modulated or variable light intensity for the
light source 30.
[0322] Modulated light intensity may be regulated by the controller
50 to create the appearance of rotation within a single support 12
or in conjunction with multiple separated, independent or adjacent
supports 12 for the provision of a composite emergency warning
light signal.
[0323] The controller 50 may also provide for the random generation
of light signals without the use of a preset pattern of variable
light intensity. Controller 50 provides a means for activating
LED's 30 individually to allow for greater flexibility in the type
of warning light signal created. This embodiment of the invention
is also capable of displaying information in a variety of different
colors or sequential illumination of colors.
[0324] Referring to FIGS. 33, 34, and 35, the emergency vehicle 300
includes a light bar or light support 302 which may include one or
more panels of LED light sources 306. A strip LED light source 308
may also be secured to the exterior of the emergency vehicle 300 at
any location. It is anticipated that the strip LED light source 308
may encircle an emergency vehicle 300 to enhance the visualization
of the emergency vehicle 300 positioned proximate to an emergency
situation.
[0325] Referring to FIG. 34, the strip LED light source 308 is
comprised of a circuit board 310 having an array 312 of individual
LED light sources 306. The LED light sources 306 are in electrical
communication with each other via electrical contacts 314. Each
circuit board 310 is in electrical communication with a power
supply and/or controller 50 via the use of wires. Each individual
LED light source 306 as included within a strip LED light source
308 may be enclosed within a reflector 370 to facilitate and
maximize light output along a desired visual line of sight. (FIGS.
26-30) The LED light sources 306 have maximum illumination at an
angle of incidence approximately 40.degree.-45.degree. downwardly
from vertical. The strip LED light sources 308 also include a
back-side. The back-side includes an adhesive, magnetic, or other
affixation device which may be used to secure the strip LED light
sources 308 to the exterior of an emergency vehicle 300 in any
desired pattern or location. The strip LED light sources 308 may
also be enclosed within a transparent cover 324 which prevents
moisture or other contamination from adversely affecting the
performance of the LED light sources 306 during use. (FIGS.
31-32)
[0326] Wires of adjacent strip LED light sources 308 may be
intertwined to extend across a vehicle for coupling to a power
supply at a central location. The wires may be connected to the
controller 50 which may be used to regulate the illumination of
individual LED light sources 306 and/or individual panels of the
strip LED light sources 308 to provide the types of light signals
previously identified herein. The individual LED light sources 306
within the strip LED light source 308 may be of a single or variety
of colors as earlier described. Adjacent strip LED light sources
308 may be electrically coupled to each other in parallel or series
electrical connections for electrical communication to a centrally
located controller and power source.
[0327] The individual LED light sources 306 as incorporated into
the array 312 of the strip LED light sources 308 are sturdy and do
not fail or separate from a vehicle 300 when exposed to rough
operating conditions. The transparent cover 324 for the strip LED
light sources 308 may be formed of sturdy and resilient plastic
material which prevents water penetration and/or contamination to
the circuit board 310 and/or individual light sources 306.
[0328] The strip LED light sources 308 may individually be formed
into supports of any size. It is anticipated that the strip LED
light sources 308 may have the approximate dimensions of three
inches in length, three inches in width, and one-half inch in
thickness for use in affixation to the exterior of an emergency
vehicle 300.
[0329] Referring to FIG. 35, a panel 304 of individual LED light
sources 306 is depicted. The panel 304 may form the illumination
element for the strip of LED light sources 308 and/or light bar 70
or light support 12, 302 as affixed to an emergency vehicle 300.
Each panel 304 contains a plurality of rows 34 and columns 32, 328
of individual LED light sources 306. The panels 304 are in
electrical communication with the controller 50 and power supply
(now shown). The panels 304 may be controlled individually to
create a desired warning light signal for an emergency vehicle 300.
Each panel 304 may be controlled as part of an overall warning
light signal or pattern where individual panels 304 or combinations
of individual panels 304 may be illuminated to provide for the
appearance of rotation and/or oscillation through the selective
illumination of light sources or through the use of a modulated
light intensity light source.
[0330] The strip LED light sources 308 may be organized into
distinct sections, segments, and/or sectors 326 for individual
illumination by the controller 50. Each distinct segment, section,
and/or sector 326 may therefore be illuminated with a visually
different and distinct type of light signal with, or without,
modulated or variable light intensity for the creation of a desired
type of unique warning lighting effect for a vehicle. An infinite
variety of colors and/or patterns, combinations, or sequences of
light signals may be established for the emergency vehicle 300
through the use of the controller 50.
[0331] Modulated light intensity may be regulated by the controller
50 to create the appearance of rotation or pulsation within a
single panel 304, strip 308, or in conjunction with multiple
separated or adjacent panels 304 or strips 308 for the provision of
a composite warning light signal. The warning light signal for each
or a group of panels 304 or strips 308 may also be regulated by the
controller 50 for the provision of a modulated light intensity for
an observable warning light signal. All individual LED light
sources 306 within a panel 304 or strip 308 may also be exposed to
an incrementally increased modulated duty cycle or light intensity
to provide for the incremental increase in illumination for a
warning light signal. The modulation or light intensity curve is
anticipated to resemble a sine wave pattern when the warning light
signal provides the appearance of rotation (FIG. 43). After a
desired level of illumination has been obtained, the duty cycle for
the individual light sources 306 may then be incrementally
decreased. The duty cycle is not required to be terminated. Each
individual LED light source 306 is not required to receive the same
level of duty cycle from the controller 50. Therefore, different
individual LED light sources 306 may receive different duty cycles
within a single warning light signal. Individual LED light sources
306 within panel 304 are not required to be simultaneously and
incrementally illuminated to provide for the appearance of
rotation. It is anticipated that a pulsating and/or modulated
variable light intensity may be provided by the controller 50 for
regulation of the duty cycle from thirty percent to maximum and
back to thirty percent which affords a desirable type of pulsating
modulated variable light effect.
[0332] The provision of a modulated light intensity to the panels
304 may also be coupled with, or in combination to, the sequential
illumination of columns 328 as earlier described. In this
situation, the warning light signal may initially be dim or off as
the individual columns 328 are sequentially illuminated and
extinguished for illumination of an adjacent column or columns 328.
The duty cycle or light intensity for the illuminated column or
columns 328 may simultaneously be incrementally increased for a
combination unique rotational and pulsating modulated light signal.
In addition, the controller 50 may be programmed to provide the
appearance of rotation pulsation and/or oscillation or for
illumination of other types or combinations of types of lighting
effects.
[0333] The provision of a modulated light intensity may be
implemented in association with a light bar or light support 302, a
cylindrical panel, a strip of lights 308, flat panels 304, or any
other type of light source as described herein.
[0334] Referring to FIGS. 48 and 49, an individual LED light source
306 is depicted in detail. The LED light source 306 may include a
ceramic and/or heat resistant base 334. Centrally within the
ceramic and heat-resistant base 334 is positioned a light source
336. The light source 336 may be enclosed within a protective cover
338. Extending outwardly from the individual light source 306 are a
pair of contact paddles 340 which provide for the electrical
contacts for illumination of the light sources 336 during use. The
back of the LED light source 306 includes a slug 342. The slug 342
is designed to be positioned within circular openings 344 of a
circuit board or LED mounting surface 346 (FIG. 36). The circuit
board or LED mounting surface 346 establishes a heat sink within an
aluminum base or frame 348 as depicted in FIGS. 38 and 39. The LED
light sources 306 as depicted in FIGS. 48 and 49 provide for a
light intensity varying between 20 and 200 lumens or higher. The
positioning of the slug 342 in the circular openings 344 of the
circuit board or LED mounting surface 346 assists in the
establishment of the heat sink. A heat sink is desirable because
the individual LED light sources 306 may have a sufficient level of
power output during use to develop heat. As a result, the slugs 342
are positioned within the circular opening 344 and may be fully
engaged to an adhesive for affixation to an aluminum base 349
(FIGS. 38 and 39). This combination assists in the dissipation of
heat during use of the individual LED light sources 306 enhancing
the performance of the light support 302.
[0335] As may be seen in FIGS. 31, 32, 37, 38, 39, and 50, in an
alternative embodiment, the light bar, light support 302, or panel
304 may be formed of a single row of LED light sources 306. Within
this embodiment, the LED light sources 306 are positioned within
circular openings 344 of circuit board or LED mounting surface 346
(FIG. 37). Circuit board 346 may be affixed to aluminum base 348
through the use of adhesive including glass beads where the
circular openings 344 assist in the establishment of a heat sink
for the individual LED light sources 306. The use of adhesive
including glass beads to affix the LED light sources 306 and
circuit board 346 to the aluminum base 348 assists in the creation
of electrical contact for the light bar or light support 302.
[0336] As depicted in FIGS. 37, 38, and 39, the top surface of the
circuit board or LED mounting surface 346 may include two
reflectors or mirrors 350. The reflectors or mirrors 350 are
preferably elongate and are positioned substantially parallel to
each other and are adjacent or aligned to the row of individual
LED's 306. The reflectors or mirrors 350 diverge upwardly and
outwardly from a position proximate to the LED light source 306 and
aluminum base 348. As such, the mirrors 350 have a separation
distance which is narrow proximate to the LED light sources 306,
where the separation distance becomes larger as the distance
vertically from the aluminum base 348 increases.
[0337] The brightest or most intense light of the individual LED
light sources 306 is provided at an acute angle of approximately
40.degree. to 42.degree.. The reflector or mirror 350 as angled
upwardly and outwardly relative to the row of LED light sources 306
reflects light exiting the LED light sources 306 along a desired
line of sight which corresponds to perpendicular observation by an
individual. The reflectors or mirrors 350 maximize the efficiency
of the light sources 306 by reflecting light along the line of
sight to be observed by an individual during an emergency
situation. The reflectors or mirrors 350 may have a polished or
non-polished surface depending on the brightness desired for the
light support 302. The reflectors or mirrors 350 may also include
one or more reflective sections 374 and/or transparent or clear
sections 372. The transparent or clear sections 372 and the
reflective sections 374 are described in detail with reference to
FIGS. 26-30 below. The surface of the reflectors or mirrors 350 may
also include any desired combination of sections, patterns,
stripes, rows, and/or columns of clear or transparent sections 372
and/or reflective sections 374 for reflection of light illuminated
from the individual LED light sources 306 during the provision of a
warning light signal.
[0338] Wires 354 connect the circuit board 346 to the power supply
and controller 50. A modulated light source may thereby be provided
to the light support 302 which includes the reflector or mirrors
350. In this embodiment, the sequential illumination of individual
LED's 306 may occur to provide a desired type of warning light
signal. Also, the circuit board 346 as engaged to the base 348 may
be separated into segments 326 of LED light sources 306 for use in
combination with a modulated light intensity electrical source.
[0339] As depicted in FIGS. 38 and 39, the frame 348 includes a
base 349. The base 349 may include a holding cavity 358. In the
holding cavity 358 is preferably positioned a circuit board or LED
mounting surface 360 which includes a plurality of circular
openings 344. In each circular opening 344, is positioned an
individual LED light source 306. Above the holding cavity 358 is a
first support 362 and a second support 363. The first support 362
and second support 363 have an angled interior edge 364. Each
angled interior edge 364 is adapted to receive a reflector or
mirror 350. Each mirror 350 is utilized to reflect light
illuminated from an individual light source 306 along a visual line
of sight as depicted by arrow AA of FIG. 39. The first and second
supports 362, 363 may also include a positioning ledge or notch 366
which is adapted to receive a glass or transparent plastic cover
lens 368 which serves as a protector for the frame 348 and
individual LED light sources 306.
[0340] Referring to FIG. 50, the frame 348 may be elongate having a
first end 380 and a second end (not shown). The first end 380 and
the second end each include and affixation area 382 which may be
threaded for receiving engagement to a fastener 384. A bracket 386
may be rotatably engaged to the first end 380 and second end by
tightening of the fasteners 384 relative to the affixation areas
382. The bracket 386 includes and angled portion 388 which may
include a second fastener 390 which may be formed of suction cups.
Alternatively, the second fastener 390 may be screws, bolts, and/or
rivets for attachment of the frame 348 at a desired location
relative to the interior or exterior of a vehicle 300.
[0341] Referring to FIGS. 26-30, a reflector or culminator for the
individual LED light sources 306 is disclosed. The reflector or
culminator is indicated in general by the numeral 370. The
reflector or culminator 370 may be conical in shape and may be
configured to encircle an individual LED light source 306. The
reflector or culminator 370 may also be partially transparent. The
reflectors 370 may be formed of clear sections 372 and/or
reflective sections 374. In FIG. 29, the clear section 372 is
positioned proximate to the LED light source 306 and the reflective
section 374 is positioned to the top of the reflector 370.
[0342] In FIG. 28, the reflective section 374 is positioned
proximate to the LED light source 306 and the clear section 372 is
positioned to the top of reflector or culminator 370. As may be
seen in FIG. 30, the entire interior surface of the reflector or
culminator 370 may be formed of a reflective section 374. A
plurality of clear sections 374 may be utilized within each
reflector or culminator 370.
[0343] The use of a combination of clear sections 372 and
reflective sections 374 enable an individual to select a
configuration for the provision of partial illumination along an
angle which is not parallel to a desired line of sight. An
individual may thereby observe an illuminated light signal from the
side or top of a light bar or light support 302 as opposed to being
aligned with a desired line of sight.
[0344] Each of the culminator or reflector cups 370 includes an
angled interior surface which extends upwardly and diverges
outwardly from a central opening 394. Each central opening 394 is
constructed and arranged for positioning approximate to and over an
LED light source 306. Each of the culminator or reflector cups 370
also preferably includes an angled exterior surface which extends
upwardly and diverges outwardly from a bottom or base which is
positioned approximate to an LED mounting surface or circuit board
346.
[0345] Referring to FIG. 26 a plurality of culminator cups or
reflectors 370 may be formed into a culminator assembly or array
392. The culminator assembly or array 392 is adapted for
positioning over an array of LED light sources 306. Examples of
arrays of LED light sources 306 which may be utilized with a
culminator assembly 392 are depicted in FIGS. 3-10, 12, 14, 15,
23-25, 31, 32, 34, 35, 37, 39, 40, 44, and 47.
[0346] Each culminator array 392 is formed of a reflective material
which has plurality of reflective cups 370 disposed there through.
Each opening 394 is adapted for positioning over an LED light
source 306. The culminator array 392 has a sufficient thickness to
establish an interior reflective surface having a sufficient
dimension to reflect light as emitted from the LED light sources
306. Alternatively, the interior surface of each reflector cup 370
may be entirely or partially coated with reflective material. The
entire culminator assembly 392 is not required to be formed of
reflective material provided that the interior surface of the
reflector cups 370 are coated at least partially with reflective
material.
[0347] The culminator array 392 may be formed in any shape
including but not necessarily limited to square, rectangular,
triangular, linear, circular, oval, and special or other irregular
shapes for use in reflecting light emitted from an LED light source
306. The interior surface of any desired number of culminator cups
370 may also be coated with reflective 374 and non-reflective 372
sections as earlier described.
[0348] The strip LED light source 308 and LED light sources 306 in
frame 348 are designed to operate on a 12 volt power supply which
is available in a standard emergency vehicle battery. The frame 348
and strip LED light source 308 are enclosed in a waterproof
protector to minimize the risk of contamination or failure from any
exposure to moisture or dust or dirt. The use of the strip LED
light sources 308 and frame 348 minimize the necessity to modify
the exterior of an emergency vehicle 300 through the placement of
holes or other apertures. In these embodiments, the wires 354 and
316 may be adhesively secured to the exterior of a vehicle for
entry into the power source and controller 50 at a common
location.
[0349] The strip LED light sources 308 may be used on other devices
and are not necessarily limited to use on an emergency vehicle 300.
It is anticipated that the strip LED light sources 308 may be used
on a variety of apparatus including but not limited to snowmobiles,
water craft, helmets, airplanes, or any other device which may
accept use of an LED light source.
[0350] In FIGS. 40-43 a warning signal light 400 is depicted which
in general includes a light source 402 and a rotatable reflector
404. The light source 402 may include one or more individual LED
illumination devices 406. The light source 402 may include a base
408 which may be mounted on a post 410. The light source 402 may
either be stationary or rotate as desired.
[0351] A motor 412 is electrically connected to a power supply for
rotation of a wheel or gear 414. The wheel or gear 414 is connected
to the motor 412 by a shaft 416. The wheel or gear 414 is in
contact with, or is engaged to, a rotatable collar 418 which may be
adapted to rotate freely about the post 410 during operation of the
motor 412. The wheel or gear 414 may be formed of rubber material
or any other desired material. Alternatively, the wheel 414 may
include teeth and function as a gear for engagement to
corresponding grooves and teeth as integral to the exterior surface
of the collar 418.
[0352] An aperture 420 may pass through post 410 to receive wires
422 for the provision of power to LED light source 402. A washer or
support device 424 vertically supports rotatable collar 418 on post
410 from a position below collar 418. A positioner 426 functions to
restrict the vertical movement of the collar 418 upwardly during
engagement of the motor 412 and rotation of the wheel 414 and
collar 418.
[0353] A horizontal support arm 428 extends outwardly from collar
418. A vertical support arm 430 extends upwardly form horizontal
support arm 428. Angular support arm 432 extends inwardly and
upwardly from vertical support arm 430 for positioning of a
reflector or mirror 434 above light source 402. The reflector or
mirror 434 is positioned at an approximate angle of forty-five
degrees relative to the light source 402. Light as emitted
vertically from the light source 402 may then reflect from the
reflector 434 along a substantially perpendicular line of visual
sight. The reflector 434 rotated ninety degrees is depicted in
phantom line as an oval due to the angular offset of approximately
forty-five degrees.
[0354] The use of motor 412 rotates wheel 414 which in turn rotates
collar 418 and reflector 434 in a circular direction about light
source 402 for the provision of an observed rotational warning
light source. In addition, the light source 402 may be electrically
coupled to a controller 50 to provide a modulated, alternating,
variable, pulsating, or oscillating light source simultaneously to
the rotation of the reflector 434 about light source 402.
[0355] Referring to FIG. 41 the warning signal light 400 includes a
light source 402 which is rotatable in conjunction with the
reflector 434. In this embodiment the motor 412 is connected to a
first gear which is enclosed within casing 436. A second gear is
also enclosed within casing 436 and is coupled to the first gear
for rotation of the reflector 434. A vertical rod 438 is affixed or
integral to the second gear. The vertical rod 438 supports the LED
light source 402 as positioned adjacent to reflector 434. An angled
brace 440 is also engaged to rod 438. Angled brace 440 supports
reflector 434 during rotation of reflector 434 which represents a
circular motion as depicted by arrow 442. In this embodiment
reflector 434 is arcuate in shape and may be parabolic. Light
emitted from light source 402 may then be reflected by the arcuate
reflector 434 along a desired line of sight. The engagement of the
motor 412 rotates the light source 402 and reflector 434 to provide
a rotational light source as observed by an individual. The light
source 402 may be coupled to a controller 50 to provide for a
modulated, alternating variable, and/or pulsating light signal in
conjunction with the rotation of the reflector 434.
[0356] Referring to FIG. 42, the reflector 434 is not required to
be flat and may include a convex or concave face 444. The provision
of a convex or concave face 444, is utilized to assist in the
creation of a unique variable light effect as observed by an
individual. Light as emitted from the light source 402 may then be
reflected at any desired angle other than perpendicular for
observation by an individual. The pulsating intensity of the light
as observed by an individual may then be unique, especially when
used in conjunction with the rotated reflector 434 and variable or
modulated light intensity from the controller 50. In addition, the
use of a convex or concave reflector 444 may expand or enhance the
observation of the warning signal light 400 by individuals beyond a
perpendicular line of sight. The warning signal light 400 may then
be observed above or below a light source 402. The reflector 434 as
rotated ninety degrees is depicted in phantom line and is generally
oblong or oval in shape.
[0357] FIG. 43 represents graphically the variable or pulsating
illumination of the observed light as reflected from the reflector
434 of FIG. 42. Time is represented along the x-axis and increasing
brightness is depicted along the y-axis. The graph of FIG. 43 shows
the gradual increase in brightness of the observed light as the
reflector 434 is rotated to a maximum illumination corresponding to
direct in line observation of the warning light signal and then the
gradual decrease in observed light intensity as the reflector 434
is rotated away from direct in line sight. The observed warning
light signal is not required to be extinguished and may be reduced
to a minimum observable intensity of approximately thirty
percent.
[0358] Referring to FIG. 44, the warning signal light 400 in
general includes a light source 402 which may be rotated through
the use of a motor 412 for transmission of light through a filter
446 for reflection from a conical reflector 448 as mounted to the
interior of a light bar or light support 450.
[0359] Power for motor 412 is supplied through wires 452 from a
power source not shown. Power for the light sources 402 is provided
through wires 454 in support 456. Brushes 458 may be in electrical
communication with the power from the wires 454 to transmit
electrical current to a second set of brushes 460 utilized to
communicate power to the light sources 402. The base 462 of the
light source 402 may preferably be formed of an electrically
conductive material to facilitate the provision of power to the
light sources 402.
[0360] A shaft 464 preferably extends between the motor 412 and the
base 462 where operation of the motor 412 causes rotation of the
shaft 464 and the base 462 having the light sources 402. Light is
transmitted vertically upward from the light sources 402 through
the filter 446. (FIGS. 44 and 45.) The filter 446 may include one
or more sections of tinted material 466. The filter 446 may be
stationary or may be rotatable. The tinted material 466 may be any
color or opaque to establish a desired illumination effect for an
emergency warning signal light. Any number of tinted sections 466
or transparent areas may be placed on the filter 446. The filter
446 may be formed of glass or plastic or other sturdy material. The
tinted sections 466 may be integral to or placed upon the filter
446 dependent upon construction considerations. The filter 446 may
be attached to the conical reflector 448 by a fastener 468.
[0361] The conical reflector 448 may include a straight reflective
edge 470. Alternatively, the reflective edge 470 may be concave or
convex to establish a unique lighting effect. The conical reflector
448 may be affixed to, and descend from, the top of a light bar or
light support 450 as may be attached to an emergency vehicle
300.
[0362] Light transmitted upwardly from the light sources 402 passes
through either a substantially transparent section or through the
tinted or opaque material 466 which may block light transmission or
alter the color of the light. Light is then reflected from the
conical reflector 448 at a desired angle for transmission through
the vertical sections of the light bar or light support 450 for
observation by an individual.
[0363] FIG. 46 represents graphically the intensity of the observed
light as reflected from the conical reflector 448 of FIG. 44. Time
is represented along the x-axis and observed brightness is
represented along the y-axis. The observed light signal transmitted
from the warning signal light of FIG. 44 is much steeper which
corresponds to a shorter period of observation more similar to a
flashing light signal. The light sources may also be coupled to a
controller 50 for the provision of a variable, modulated and/or
pulsating light effect.
[0364] Referring to FIGS. 31 and 32 a modular light support 480 in
general includes an LED mounting surface 482 having one or more LED
light sources 306, a culminator assembly 484 and a cover 324.
[0365] The LED mounting surface 482 is elongate and includes a
plurality of LED light sources 306. In general, one to five LED
light sources 306 are disposed in a linear orientation along the
LED mounting surface 482 which may be a circuit board as earlier
described. The LED mounting surface 482 also includes a first end
486 and a second end 488. An opening 490 is positioned through the
LED mounting surface 482 proximate to each of the first end 486 and
second end 488.
[0366] The culminator assembly 484 preferably includes a plurality
of reflector cup areas 492. The culminator assembly 484 also
preferably includes a plurality of support walls 494, a top surface
496, and a plurality of openings 490. Each of the openings 490 is
sized to receivingly position and hold the individual LED light
source 306 during assembly of the modular light support 480. The
reflector cup areas 492 are equally spaced along the culminator 484
to correspond to the spacing between the individual light sources
306 as disposed on the LED mounting surface 482.
[0367] The cover 324 is preferably transparent permitting
transmission of light emitted from the LED light supports 306
therethrough. The cover 324 includes a forward face 498, a pair of
end faces 500, a top face 502 and a bottom face 504. Each of the
pair of end faces 500 includes a receiving notch 506 which is
adapted to receivingly engage the LED light mounting surface 482
during assembly of the modular light support 480. An affixation
opening 508 traverses the forward face 498 proximate to each of the
pair of end faces 500. A fastener 510 passes through the affixation
opening 508 for engagement to the opening 490 to secure the LED
mounting surface 482 into the receiving notch 506. The culminator
assembly 484 is then positioned within the interior of the cover
324 where the top surface 496 is proximate to the forward face 498.
The illumination of the LED light sources 306 then transmits light
through the forward face 498 for observation of an emergency
warning light signal.
[0368] Specifically referring to FIG. 32 one or more modular light
supports 480 may be positioned adjacent to each other for the
creation of a light bar or light stick 512. The modular light
supports 480 and/or light bar or light stick 512 may be coupled to
a controller 50 which may independently and/or in combination
provide a plurality of independent and visually distinct warning
light signals as earlier described. In addition, the controller 50
may provide modulated and/or variable light intensity to the
individual LED light sources 306 to establish unique warning light
signal effects. The controller 50 may individually illuminate LED
light sources 306 to provide for one or a combination of colored
light signals as earlier described.
[0369] Any number of modular light supports 480 may be positioned
adjacent to each other to comprise a light bar or light stick 512.
A plurality of modular light supports 480 may be positioned at any
location about the exterior or within the interior of a
vehicle.
[0370] Referring to FIG. 47 an alterative embodiment of a reflector
assembly is disclosed. In general, the reflector assembly of FIG.
47 includes an enclosure 518. Positioned within the interior of
enclosure 518 is a motor 520 having a shaft 522 and a gear 524. A
first support 526 has a periphery having a plurality of teeth 528
adapted to releasably engage the gear 524. The first support 526
includes a mirror bridge 530 which is used to position a mirror 532
at an approximate angle of 45.degree. relative to a LED light
source 306. Within the interior of the first support 526 is located
a culminator assembly 534 which may include one or more reflective
cups. Individual LED light sources 306 are positioned within each
of the culminator cups of the culminator assembly 534 to maximize
illumination of emitted light for reflection from the mirror
532.
[0371] On the opposite side of gear 524 is located second support
536. Second support 536 also includes a periphery having a
plurality of teeth 528, a mirror bridge 530, a mirror 532, and a
culminator assembly 534 disposed adjacent to a plurality of
individual LED light sources 306.
[0372] A third support 538 is adjacent to the second support 536.
The third support 538 also includes a periphery having a plurality
of teeth 528, a mirror bridge 530, and a mirror 532 disposed at a
45.degree. angle above a culminator assembly 534. A plurality of
individual LED light sources 306 are disposed within the reflector
cups of the culminator assembly 534. The teeth 528 of the third
support 538 and second support 536 are coupled so that rotational
motion provided to the second support 536 by the gear 524 is
transferred into rotational motion of the third support 538.
[0373] In operation, the individual LED light sources 306 are
connected to a power source and/or a controller 50 as earlier
described. An infinite number of independent visually distinctive
warning light signals may be emitted through the use of the
rotational reflector as depicted in FIG. 47. An infinite number of
warning light signal combinations may also be provided by the
controller 50 for use with the rotational reflector of FIG. 47.
[0374] Each of the mirrors 532 may be positioned for reflection and
transmission of light to a desired field of vision relative to the
rotational reflector. A flashing and/or rotational light source may
be provided for observation by an individual.
[0375] The first support 526, second support 536, and third support
538 may be synchronized to provide for a unique warning signal
light for observation by an individual. The engagement of the motor
520 for rotation of the gear 524 simultaneously rotates the first
support 526, second support 536 and third support 538 for the
provision of a warning light signal.
[0376] LED technology enables the selection of a desired wavelength
for transmission of light energy from the individual LED light
sources 306. Any wavelength of visible or non-visible light is
available for transmission from the LED light sources 306. As such,
generally no filters are required for use with individual LED light
sources 306. The individual LED light sources 306 may be selected
to provide for any desired color normally associated with the use
in emergency vehicles such as amber, red, yellow, blue, green
and/or white.
[0377] The controller 50 may simultaneously display any number of
combinations of warning light signals. For example, the controller
50 may provide for a solitary light signal for transmission from a
light source. Alternatively, the controller 50 may effect the
transmission of two signals simultaneously from the identical light
source where a first warning light signal is emitted from one
portion of the light source and a second warning light signal is
emitted from a second portion of the light source. Alternatively,
the controller 50 may alternate two warning light signals where the
first area of the light source first transmits a first warning
light signal and secondly transmits a second warning light signal.
The second area of the light source initially transmits the second
warning light signal and then transmits the first warning light
signal. Further, the controller may transmit two independent and
visually distinct warning light signals simultaneously within
different areas of light source. The controller 50 may also reverse
the warning light signals for simultaneous transmission between
different areas of the light source. Further, the controller 50 may
regulate the transmission of more than two visually distinct types
of warning light signals from a light source at any given moment.
The controller 50 may alternate warning light signals within
different areas or enable transmission of warning light signals in
reverse alternating order for the creation of an infinite variety
of patterns of visually distinct warning light signals for use
within an emergency situation. The controller 50 may also permit
the transmission of a repetitive pattern of warning light signals
or a random pattern of visually distinct warning light signals.
[0378] Turning to the embodiment shown in FIG. 51. FIG. 51 shows a
possible configuration of a warning signal light 600 having modular
components. In the embodiment shown a light support 602 has a
plurality of module receiving ports 604. The module receiving ports
604 are constructed and arranged to provide electrical
communication respectively to a module support member 610 of a
module 606 received therein. Each of the module support members 610
may be made up of connection teeth or contacts 608 which
electrically contact and engage the receiving ports 604 when
inserted therein. Each module 606 has at least one visible light
signal display surface 612 which has one or more light sources 30
removably mounted thereon. The light sources 30 are light emitting
diodes, such as have been previously discussed. About each light
source 30 may be a culminator 370. Furthermore, each culminator 370
may include a reflective surface 616 at least partially disposed
thereon. Reflector 616 more efficiently directs the light emitted
from light source 30 in a desired direction. In an additional
embodiment of the invention the reflector 616 may be adjustable so
as to redirect and/or focus light emitted from the light source 30
during use. Also, the visible surface 612 or the individual
culminator cups 370 and reflectors 616 may also have one or more
lenses equipped thereon to provide the warning signal light with
the ability to magnify and/or diffuse emitted light.
[0379] In the embodiment shown, the module support members 610 and
the module receiving ports 604 respectively are uniform in size.
The uniformity of the ports 604 and the members 610 allows modules
606 to be readily replaced and also provides the invention with the
capacity to have variously sized and shaped modules 606 to be
interchanged and arranged in various configurations. For example a
relatively elongated module, such as is indicated by reference
numeral 606a, could be positioned in any of the various ports 604
shown and could likewise be replaced with any other module such as
the more vertically oriented module 606b, or the remaining module
type 606c. Such modularity and standardization of connections
provides the present invention with a tremendous variety of module
configurations which may be readily reconfigured as desired.
[0380] In addition to providing a variety of module types, the
present invention also provides for a variety of mechanisms to be
associated with the ports 604. In the embodiment shown for example,
a rotation mechanism 618 has a port 604 mounted thereon. Any number
of rotation mechanisms 618 could be included on the surface of the
support 602 such as is shown. Alternatively a similar mechanism or
mechanisms could be included on one or more surfaces of a module
606 to provide a dedicated rotation module. The rotation mechanism
618 could also be configured as a gyrator or other motion producing
device.
[0381] It must also be noted however that the three types module
varieties 606a, 606b and 606c presently shown and described are
merely three examples of potential module sizes and shapes. It
should be understood that modules 606 may be configured in any size
or shape as desired. As indicated above, in order to ensure the
greatest ease of use and elegance in design, it may be desirable to
provide the various modules 606 with uniform support members 610
and also provide the support 602 with similarly uniform ports 604.
However, in order to ensure that only certain module types are
utilized in certain ports, it is recognized that the present
invention could also utilize a support 602 having a variety of port
604 configurations with modules 606 having module supports 610
sized to correspond with specific ports and/or ports 604.
[0382] In keeping with the modular construction of the present
invention, it should also be understood that the support 602, like
most of the components thus described could be embodied in a
variety of shapes and sizes. Preferably, the support 602 is a
circuit board with a number of ports 604 included thereon. In one
aspect of the invention, the support 602 could be embodied as
several supports with each support having a unique arrangement of
modules and light sources. The electronic schematics shown in FIGS.
52-55 show some possible configurations and their associated
electronic connections between the various components of the
invention.
[0383] Starting in FIG. 52, an embodiment of the invention is shown
where the controller 50 is in electronic communication with one or
more supports 602, which are in turn in electronic communication
with one or more modules 606, which are in turn in electronic
communication with one or more light sources 30. FIG. 53 shows a
similar series of electric pathways, but in the present embodiment
the controller 50 may also be in direct electric communication with
each of the various components, support(s) 602, module(s) 606 and
light source(s) 30, independent of one another.
[0384] In the embodiment shown in FIG. 54, the individual visible
surfaces 612 of the various modules 606 may be controlled by the
controller 50. Though not indicated in the schematic, the various
components supports 602, modules 606, visible surfaces 612 and
light sources 30 may be independently controlled by the controller
50 or may be selectively activated via the electronic pathway
shown.
[0385] In the embodiment shown in FIG. 55, a support 602 includes a
controller 50. Each controller 50 is in electronic communication
with an external controller 55 in the manner previously discussed.
The embodiment shown in FIG. 55 may include numerous independently
controlled supports 602 which are in communication with the
external controller 55. Individual controllers 55 may also be
included with each modules 606 to provide for a warning signal
light having numerous predetermined light signals or patterns which
may be displayed by sending a single signal from the external
controller 55 to the various controllers 50.
[0386] In reference to the various embodiments shown in FIGS.
52-55, additional components may be added to any of the various
embodiments shown and that numerous configurations other than those
shown or described could be created. The present invention is
directed to all possible arrangements of the various components
described herein regardless of the number, type or arrangement of
the components described herein.
[0387] The controller 50 and/or external controller 55 described in
relation to FIGS. 52-55 may provide modulated and/or variable
illumination to individual light sources 30 or modules 606. The
controller 50 or external controller 55 may selectively illuminate
any combination of individual light sources 30 or modules 606 to
provide an infinite variety of patterns and/or combinations of
patterns for a warning light signal independently of, or in
combination with, the provision of modulated or variable light
intensity.
[0388] Turning to FIGS. 56-58, several views of an example of a
module 606 is shown. Typically, a module will include a base
portion 620 and light mounting portion 622. The base portion 620
will include the support member 610 which will typically include a
plurality of electric contacts 608. The support member 610 and the
electric contacts 608 are removably engageable to a port 604. The
contacts 608 provide the module 606 with an electric path to the
support 602 and controller 50 such as is shown in FIGS. 51-55.
[0389] The light mounting portion 622 preferably is a vertically
oriented circuit board 630 which includes one or more light sources
30 and associated culminator cups 370 with reflective surfaces 616
removably mounted thereon. The light sources are preferably LEDs.
As shown in FIG. 51 the light mounting portion 622 may be enclosed
in a transparent cover or dome such as protector 290.
[0390] As depicted in FIGS. 61, 62, 65, and 66, an LED take-down
light 700 and an LED alley light 702, 800, 808 are shown as being
integral to a light bar 704, 760 mounted to an emergency vehicle
706.
[0391] The LED take-down light 700 may include one or more LED's
336. The LED's 786 forming the LED take-down light 700 may each be
surrounded by a culminator 370 as depicted and described with
reference to FIGS. 26-32 having one or more reflective sections 374
for transmission of light along a desired line of illumination.
Alternatively, a reflector 350, 434 may be positioned adjacent to
LED light sources 336 as described in reference to FIGS. 37-47. The
reflector 350, 434 used in conjunction with take-down light 700 may
be stationary or may be rotatable through the use of a rotational
device. The LED's 786 forming the LED take-down light 700 may also
be angularly offset with respect to horizontal to provide
illumination along a preferred line of illumination as depicted
with reference to FIGS. 13 and 14.
[0392] The LED take-down light 700 may be integral to, or mounted
upon, the light bar 704, 760. The LED take-down light 700 may be
formed of panels or modules of LED illumination sources as depicted
and described in FIGS. 31-32 and 51-58. The LED take-down light 700
may also include circuit boards as earlier depicted and described
further using culminator reflectors 370, within a frame or support
assembly.
[0393] The use of an LED take-down light 700 incorporating LED
technology improves illumination of areas in front of an emergency
vehicle by flooding the area occupied by a stopped vehicle with
light while simultaneously secreting the actions and location of
law enforcement personnel during law enforcement activities. The
illumination of the LED take-down light 700 also assists in
enhancing the visibility of an emergency vehicle during dark
illumination conditions which in turn improves the safety for law
enforcement personnel.
[0394] The LED take-down light 700 is preferably coupled to a power
supply, battery, or other low voltage power source. The take-down
light 700 may also be electrically coupled to a controller 50 for
illumination of all or part of the LED light sources 786 to provide
for a desired level of illumination for an area adjacent to an
emergency vehicle. The controller 50 may alternatively provide one
or more of the many types of light signals as earlier
described.
[0395] Further, the intensity of the LED light sources 786 may be
selectively regulated by a controller 50 dependent upon the
darkness of the conditions to be illuminated during law enforcement
activities. The controller 50 may be coupled to a light or
photosensitive detector to assist in the selection of a desired
level of light output dependent upon the environmental conditions
encountered by the law enforcement personnel during use of the LED
take-down light 700.
[0396] The LED take-down light 700 may be formed of one or more
adjacent panels or modules 784 of LED illumination sources 786
along a front face 710, 764 for a light bar 704, 760.
Alternatively, a plurality of panels or modules 784 of LED light
sources 786 may be formed along the front face 710, 764 of the
light bar 704, 760 as well as a plurality of panels or modules 784
of LED light sources 786 along the rear face 712, 776 of the light
bar 704, 760. The panels or modules 784 selected for the LED
illumination sources 786 may be linear, square, rectangular and/or
may have two or more sides, or may be a single illumination source.
Each individual panel or module 784 of LED illumination sources 786
may be independently illuminated by a controller 50 to provide one
of a plurality of individual and distinct warning light effects.
For example, a first, third, and fifth panel or modules 784 of LED
sources 786 may be illuminated where the second and fourth panels
or modules 784 are not illuminated. Alternatively, the first,
third, and fifth panels or modules 784 of LED light sources 786 may
be continuously illuminated and the second and fourth panels or
modules 784 may be illuminated to provide a flashing or strobe
light signal. Illumination of any combination of panels or modules
784 may be provided to create a preferred unique warning light
signal for the LED take-down light 700. A constant illumination
signal may be provided or a flashing, strobe, and/or modulated
light intensity may occur to provide one of a plurality of distinct
light signals for use within an emergency situation.
[0397] The LED light sources 786 within the LED take-down light 700
may be angularly offset as depicted within FIG. 14 to provide a
maximum illumination at a preferred distance adjacent to the front
of a law enforcement vehicle.
[0398] The LED take-down light 700 may be releasably secured to the
top of an emergency vehicle or light bar 704, 760 through the use
of standard affixation mechanisms including, but not limited to,
the use of suction cups, hook and loop fasteners, brackets, screws,
bolts, and/or other fasteners. The LED take-down light 700 may be
permanently secured to a light bar 704, 760 or may be releasably
attached thereto for separation and use as a remote beacon as
described in reference to FIG. 15.
[0399] The take-down light 700 may alternatively be formed of
strips of LED light sources 308 as previously disclosed in
reference to FIG. 34. During use of strip LED light sources 308 a
culminator/reflector 370 may be used for positioning adjacent to
each individual LED light source 336 to reflect light along a
desired line of illumination. The strip LED light sources 308 may
preferably include adhesive backing material. The adhesive backing
material may be used to permanently or releasably secure the strips
of LED light sources 308 in a desired location within the LED
take-down light 700. Alternatively, the take-down light 700 may be
integral to light bars previously illustrated and described.
[0400] As depicted in FIGS. 61, 62, 65, and 66, the LED alley
lights 800, 808 provide perpendicularly outward illuminating areas
adjacent to the drivers side and passengers side of the vehicle
706. The LED Alley lights 800, 808 are almost identical in
construction and functionality to the LED take-down light 700. The
LED alley lights 800, 808 may be mounted to a mechanical pivot,
gears, and/or rotational device which may include an electric
motor. The rotation of the mechanical pivot, or gears may
alternatively be terminated to permit fixed angular illumination of
areas adjacent to a law enforcement vehicle 706 which are not
perpendicular to either the drivers or passenger sides in a manner
similar to the functionality and operation of a spot light. In this
regard, the LED alley lights 800, 808 may be manipulated forwardly,
rearwardly, upwardly, and/or downwardly to provide illumination of
a desired area relative to an emergency vehicle 706.
[0401] The LED alley lights 800, 808 may be integral to, or
removable from, the opposite ends of light bar 704, 760. As such,
the LED alley lights 800, 808 may be releasably secured to opposite
ends of the light bar 760 through the use of fasteners such as
bolts and nuts, screws, adhesives, straps, and/or hook and loop
fabric material. An individual may simultaneously illuminate the
LED take-down light 700 and the LED alley lights 800, 808 or may
alternatively illuminate the LED alley lights 800, 808
independently from the LED take-down light 700 within an emergency
situation.
[0402] Referring to FIGS. 61, 62, 65, and 66, the take-down light
700 may be positioned inside of a housing, base, or enclosure 780
which has a transparent surface 782 permitting light as emitted
from LED light sources 786 to pass therethrough. Within the
interior of the base/housing 780 are located one or more light
emitting diode light modules 784. Each LED light module 784 may
include one or more individual light emitting diodes 786 as
integral to circuit board 788. The functions and operation of LED
light sources, LED's, and circuit boards are identical to the light
sources described in reference to FIGS. 31 and 32. Each LED light
module 784 may also include electrical couplers or connectors 790
which may be adapted for penetrating engagement into a receiving
slot 792. The LED light modules 784 as earlier described with
reference to FIGS. 51-58 facilitate ease of replacement herein. An
individual may thereby easily replace and/or substitute an LED
light module 784 with another LED light module having the same or
different colors or intensity characteristics. The circuit board
788 and/or LED light modules 784 may be panels or strips as
described with reference to FIGS. 34 and 35.
[0403] The LED lights 786 are preferably spaced about circuit board
788 in any pattern and/or combination including the use of a linear
configuration. Adjacent to each LED light module 784 is positioned
a reflector which may be a culminator 730, 534, as earlier
described in reference to FIGS. 26-32 and 47. Alternatively, a
reflector or mirror 802, 434, 350, as described in reference to
FIGS. 21, 22, 37-39, 40-42, and 47, may positioned adjacent to LED
light modules 784 to reflect light emitted by LED's 786 in a
desired direction for maximization of illumination characteristics
for the alley lights 800, 808 and/or take-down light 700. The
utility of the alley lights 800, 808 and/or take-down light 700 is
thereby enhanced. The reflectors 370, 534, 434, 802, or 350 may be
integral and/or attached to circuit board 788, a frame, or to a
support adjacent to circuit board 788 to reflect light emitted from
LED's 786 in a desired direction.
[0404] Within the housing/enclosure 780 is located a motor 794
having a worm gear 796 engaged to a shaft 798. Engagement of motor
794 rotates shaft 798 in turn rotating worm gear 796. The motor 794
is electrically coupled to the electrical system and/or controller
50 for the emergency vehicle.
[0405] A first alley light 800 may be positioned within housing 780
proximate to motor 794. The first alley light 800 may be stationary
and/or rotatable relative to the light bar 760. The first alley
light 800 may or may not be engaged to a gear 804. If rotation of
the first alley light 800 is desired, then gear 804 may include a
receiving slot 792 to provide electrical connection and power to
the LED light module 784 for provision of light. Gear 804 may also
be coupled to worm gear 796 for the provision of rotation and/or
oscillation motion. If motion of first alley light 800 is not
desired, then stationary positioning of LED light modules 784
relative to housing 780 may be provided with suitable electrical
connection to a vehicle power source.
[0406] Take-down light 700, first alley light 800, and second alley
light 808 may be alteratively formed in any shape as earlier
described in reference to FIGS. 4-10, 12, 23-25, 31, 32, 34, 35,
37-39, 51, and 56-58. Take-down light 700, first alley light 800,
and second alley light 808 may be stationary within housing
780.
[0407] A second gear 806 may be provided for central positioning
within housing 780. The second gear 806 may be coupled to gear 804
which may in turn be coupled to worm gear 796 as connected to shaft
798. Rotation of shaft 798 by motor 794 thereby imparts rotation of
gear 804 and second gear 806. Alternatively, the shaft 798 may be
elongate including worm gear 796 for direct coupling to second gear
806. Rotation of 360.degree. or oscillating rotation of second gear
806 may therefore be provided.
[0408] Second gear 806 may also include a receiving slot 792
adapted to receivingly engage electronical connectors 790 as
integral to circuit board 788 of LED light modules 784. Light
modules 784 also include a plurality of individual LEDs 786 which
may each be positioned within a culminator 534, 370, 802. A
controller 50 may be electrically connected to each LED light
modules 784 as coupled to gear 804, second gear 806, third gear
810, and/or housing 780 for selectively illumination of individual
LED's 786, or for illumination of any combination of LED's 786. The
features as earlier described for controller 50 are equally
applicable for use with the take-down light 700, first alley light
800, and second alley light 808, relative to distinct types and
combinations of types of warning light signals.
[0409] Second gear 806 may be further coupled to third gear 810
which may include a receiving slot 792 adapted for electrical
coupling to connector 790 of take-down light 700. Second alley
light 808 is designed to be rotated and to sweep forwardly to the
front of an emergency vehicle at such times when the intersection
clearing light mode has been activated. During activation of the
intersection clearing light mode, the take-down light 700 as
electrically coupled or integral to third gear 810 will rotate
sweeping to the outside front corner of an emergency vehicle.
[0410] The controller 50 is in electrical communication with the
take-down light 700, the first alley light 800, and the second
alley light 808. Any number of take-down lights 700 or alley lights
800, 808 may be used in association with a light bar 704, 760. The
controller 50 may additionally regulate the rotation of the motor
794 for imparting rotation to the take-down light 700, and/or the
alley lights 800 and 808.
[0411] The controller 50 activating the motor 794 may selectively
initiate an intersection clearing illumination mode or sequence.
Motor 794 causes the shaft 798 to rotate imparting motion to the
worm gear 796. The rotation of the worm gear 796 may then be
transferred to the first alley light 800 through coupling to the
first gear 804. Alternatively, the worm gear 796 may be directly
coupled to the second gear 806. In another embodiment, motion may
be imparted to the second gear 806 through the use of a tie bar 824
as connected between the second gear 806 and the first gear 804.
Rotation of the worm gear 796 rotates first gear 804 whereupon
motion may be transferred to the second gear 806 for movement of
the second alley light 808. Rotation may be further transferred to
the take-down light 700 via the coupling of the third gear 810 to
the second gear 806. The tie bar 824 may extend between gear 804
and second gear 806 to synchronize motion, rotation, and
illumination of the first alley light 800 relative to the second
alley light 808 and take-down light 700.
[0412] Each of the first alley light 800, second alley light 808,
and take-down light 700, are in electrical communication with a
power source for a vehicle and are further in communication with
the controller 50. The controller 50 may independently impart
motion to the take-down light 700, first alley light 800, and
second alley light 808. The alley lights 800, 808, and take-down
light 700 may be selectively illuminated without initiation of
rotational motion as regulated by the controller 50. Alternatively,
the controller 50 may signal engagement of the motor 794 to impart
rotation to any one of the first alley light 800, second alley
light 808, and/or take-down light 700 for use as an intersection
clearing light. The controller 50 is therefore capable of
simultaneously regulating motion of the rotational devices such as
gears 804, 806, and 810 and illumination of selected individual or
groups of LED's 786 to provide independent or combination light
effects.
[0413] The intersection clearing light mode may generally be
initiated by the controller 50 which signals motor 794 to rotate
second gear 806 either through rotation of first gear 804 or
through direct contact with worm gear 796. The first or at rest
position for the second alley light 808 directs the transmission of
light in the direction depicted by arrow 812 which is generally
perpendicular to the longitudinal axis of a vehicle. As the
intersection clearing light mode is engaged, the counter clockwise
rotation of gear 804 causes the clockwise forward rotation of the
second gear 806 according to arrow 814 until an angle of forward
rotation 816 is achieved. The direction of forward rotation 816
transmits light emitted from LED light modules 784 forwardly
towards a corner of a vehicle at an approximate angle .varies. of
45.degree.. The controller 50 may then continue to rotate the gears
804, or 806, in a counter clockwise direction for 360.degree.
rotation, or alternatively the controller 50 may signal the motor
794 to reverse direction to rotate the second alley light 808
rearwardly back to the first at rest position indicated by number
812. During the clockwise rotation of the worm gear 796, the second
gear 806, third gear 810 and take-down light 700 may be rotated in
a counter clockwise direction. The initial at rest position for the
take-down light 700 is forwardly with respect to the alley lights
800, 808.
[0414] The engagement of the intersection clearing light mode
rotates the take-down light 700 outwardly towards the sides of an
emergency vehicle from a first position indicated at 818 to a
second position indicated at 820 as depicted by arrow 822 of FIG.
65.
[0415] Alternatively, the first alley light 800 may be rotated
simultaneously with the second alley light 808 by engagement
between the first gear 804 and second gear 806. Synchronous
rotation between the first alley light 800 and the second alley
light 806 may be provided through the use of the tie bar 824 or
through direct coupling engagement of gears 804 and 806.
[0416] In an alternative embodiment as depicted in FIG. 66, the
first gear 804 is not required to be connected to the second gear
806 with the exception of the tie bar 824. The tie bar 824 extends
between the first gear 804 and the second gear 806 and is pivotally
and rotatably engaged to each of the first and second gears 804,
806 respectively. The initial positioning of the tie bar 824 on the
first gear 804 may be initially indicated as the at 0.degree.
location. The initial position of the tie bar 824 on the second
gear 806 may also be initially indicated as the at 0.degree.
location where the tie bar 824 extends in a linear direction
between the first and second gears 804, 806 proximate to the
circumference of each of the first and second gears 804, 806
respectively.
[0417] The second alley light 808 is initially positioned for
transmission of light outwardly from the housing 780 opposite to
the location of the tie bar 824. The second alley light 808 is
positioned for light transmission at a location approximately
180.degree. from the tie bar 824 on the second gear 806.
[0418] As the motor 794 is engaged, the first gear 804 may be
rotated in either a clockwise or counter clockwise direction
relative to the housing 780. A clockwise rotation of the first gear
804 will be described herein for transfer of motion to the second
gear 806 and third gear 810. Alternatively, the motor 794 may be
configured to rotate the first gear 804 in a clockwise direction
for a desired period of time or distance, and then reverse
directions for counterclockwise rotation of the second gear 806 for
a desired period of time or distance. In an oscillating sequence
the first gear 804 may be initially rotated 90.degree. in a
clockwise direction or counter clockwise direction and then the
direction of rotation may be reversed for rotation of 90.degree. or
180.degree., whereupon rotation may again be reversed for continued
rotation of either 90.degree. or 180.degree. in the initial
direction.
[0419] In a 360.degree. rotation cycle of the first gear 804 in a
clockwise direction, motion is transferred to the second gear 806
and third gear 810 in a push-pull configuration through the tie bar
824. Clockwise rotation of the first gear 804 from a position of
0.degree. to a position of approximately 90.degree. causes the
second gear 806 to be pulled by the tie bar 824 moving the position
of the second alley light 808 from an initial position of
180.degree. to a position of approximately 270.degree.. Continued
rotation of the first gear 804 from a position at 90.degree. to a
180.degree. location preferably causes the second gear 806 to be
pushed by the tie bar 824 causing the second alley light 808 to be
rotated in a reverse direction from a 270.degree. position back to
a 180.degree. position. Continued rotation of the first gear 804 in
a clockwise direction from a position 180.degree. to a 270.degree.
location, in turn causes the tie bar 824 to pull the second gear
806 causing the second alley light 808 to continue to be rotated in
a reverse direction from a position of 180.degree. to a 90.degree.
location. Continued rotation of the first gear 804 in a clockwise
direction from a 270.degree. position to a 360.degree. or initial
position in turn causes the tie bar 824 to push the second gear 806
causing the second alley light 808 to reverse directions to be
rotated from a 90.degree. position to an initial or starting
position of 180.degree..
[0420] Rotational motion is also, in turn, transferred to the third
gear 810 due to the coupling engagement with the second gear 806.
The rotational motion of the third gear 810 relative to the second
gear 806 is in the opposite direction. The initial positioning of
the take-down light 700 on the third gear 810 is offset relative to
the second alley light 808. The initial positioning of the second
alley light 808 may be indicated as 180.degree. and the initial
position of the take-down light 700 may be initially indicated as
270.degree.. The third gear 810 and the take-down light 700 are,
therefore, initially rotated from 270.degree. in a counter
clockwise direction to approximately 180.degree.. The rotation of
the third gear 810 and the take-down light 700 is then reversed
from 180.degree. back to 270.degree. and then to 360.degree. where
rotation may be reversed back to 270.degree.. The take-down light
700 therefore wags and oscillates between 360.degree. or 0.degree.
to 180.degree. through an initial positioning of 270.degree..
Simultaneously, the second alley light 808 is wagged or oscillated
between 90.degree. and 270.degree. through an initial position of
approximately 180.degree..
[0421] The offset positioning of the second alley light 808
relative to the take-down light 700 prevents obstructed contact
between the two light modules 784 permitting free rotational motion
therebetween. The offset positioning of the second alley light 808
relative to the take-down light 700 enables the utilization of
oversized or enlarged LED light modules 784 as engaged to the
second or third gears 806, 810 respectively. The illumination as
transmitted by the LED light modules 784 may thereby be
significantly increased.
[0422] Alternatively, the rotation of the second gear 806 and third
gear 810 may occur through an arc of approximately 360.degree.. The
controller 50 is not required to continuously illuminate either the
take-down light 700, first alley light 800, and/or second alley
light 808. Alternatively, the first gear 806, and third gear 810
may be rotated to a desired position such as indicated by the
numbers 820, 816, and oscillated for return to an initial position
818, 812. The controller 50 may regulate the rotation of the gear
804, second gear 806, and third gear 810, for illumination of LED's
786 during use as an intersection clearing light. The intersection
clearing light, take-down light, and/or alley lights, are
positioned inside the housing 780 proximate to the distal ends of
LED light bar 760 as depicted in FIG. 63.
[0423] The intersection clearing lights, take-down lights 700,
and/or alley lights 800, 808, may additionally be activated by a
switch for regulation of rotation to a desired angle where upon
rotation may be terminated. In this situation, the take-down lights
700, and/or alley lights 800, 808, may be utilized in a manner
similar to a spotlight integral to a vehicle and as controlled by
an operator. The controller 50 or switch may be utilized to provide
any angle of illumination within an arc of approximately
180.degree. relative to a vehicle between an angle of approximately
45.degree. forwardly and inwardly to an approximate angle of
135.degree. rearwardly and outwardly relative to the front and
sides of a vehicle. The controller 50 or switch may also be
utilized to provide any desired angle of illumination for the alley
lights 800, 808, within an arc of approximately 140.degree.
relative to a vehicle between an angle of approximately 70.degree.
forwardly and outwardly to an approximate angle of 70.degree.
rearwardly and outwardly from the sides of an emergency vehicle. A
wide area of illumination to the front and sides of an emergency
vehicle is thereby provided by the alley lights 800, 808, and
take-down light 700 either independently and/or in combination.
[0424] In an alternative embodiment, a plurality of take-down
lights 700 may be positioned adjacent to each other and disposed
along the longitudinal length of a light bar 760 above the front
face 764 and/or rear face 766. Alternatively, the take-down lights
700 may be formed of a plurality of LED light modules 784
positioned adjacent to each other along the entire length of the
front face 764 and/or rear face 766 of a light bar 760. (FIG. 63.)
The LED light sources 336, 786 in this embodiment are connected to
the controller 50. The controller 50 may selectively illuminate one
or more LED lights 336, 786 to provide any desired intensity of
light to be used in a take-down situation by law enforcement
personnel. As depicted in FIGS. 31, 32, and 63, a single row of LED
light sources 336, 786 is disposed on front face 764 and rear face
766 of LED light bar 760.
[0425] Alternatively, a plurality of rows and/or columns of LED
light sources 336, 786 as generally illustrated and described in
relation to FIGS. 7, 9, 12, 34, and 35, may be utilized on front
face 764 and/or rear face 766. A linear culminator assembly 484
(FIGS. 31, 32), or a culminator assembly 392 in the form of an
array (FIG. 26), may be positioned adjacent to LED light sources
336, 786. Alternatively, reflectors 350 such as mirrors as
illustrated in FIGS. 37-39, may be engaged to front face 764 and/or
rear face 766 adjacent to LED light sources 336, 786.
[0426] A transparent surface 782 is preferably in sealing
engagement with the housing 780 to prevent moisture or other
contamination from adversely affecting the performance of the
take-down light 700 and/or the alley lights 800, 808. The
transparent surface 782 is preferably of sufficient strength and
durability to not fracture, break, and/or fail when exposed to
adverse environmental and/or weather conditions including but not
limited to the exposure to rock or gravel strikes.
[0427] Referring to FIGS. 59 and 60, a personal LED warning signal
light 730 is shown. The personal LED warning signal light 730 is
formed of a plurality of individual LED light sources 732 which may
provide illumination in any desired color. The individual LED light
sources 732 may be selectively illuminated by a controller 50 for
the provision of any desired combination or pattern of visually
distinctive warning light signals as earlier described.
[0428] The personal LED warning signal light 730 may be formed of
columns or rows of individual LED light sources 732 which may in
turn be sequentially illuminated to provide the appearance of a
scrolling or rotating light source.
[0429] The individual light sources 732 may be formed in an array,
panel, or single line, and may include an adhesive backing as
earlier described. Further, the individual LED sources 732 may be
angularly offset as depicted within FIG. 14 to maximize light
output along a desired line of illumination. The personal LED
warning signal light 730 includes a circuit board or LED mounting
surface 482 which may be electrically coupled to a controller 50.
The types of lighting effects available for illumination by the
personal warning signal light 730 include but are not necessarily
limited to the types of light signals and/or combinations of light
signals as earlier described.
[0430] The personal LED warning signal light 730 may also include a
culminator or reflector 370 as earlier described disposed about the
LED light sources 732. The culminator or reflector 370 preferably
assists in the maximization of light output. The culminator 370 may
also be angularly offset to conform to any angular offset of LED
light sources 732.
[0431] The personal LED warning signal light 730 may be the
approximate size of a hand held calculator for convenient
transportation within the pocket of law enforcement personnel. The
personal LED warning signal light 730 may also be enclosed within a
hard or soft sided case 734. Alternatively, the case 734 may have
an exterior appearance designed to secrete the function of the
personal LED warning signal light 730. For example, the case 734
may be configured to have a first area having a removable or
retractable cover to reveal the LED light sources 732.
Alternatively, the case 734 may be formed to resemble an article
used to transport tobacco products similar to a cigarette case.
Alternatively, the case 734 may include a removable or retractable
face which is designed in appearance to resemble a hand held
calculator, personal electronics device, and/or electronic address
book.
[0432] The personal LED warning light 730 includes a plug in
adaptor 736 which is used to establish an interface for coupling
engagement to the cigarette lighter receiver of a motor vehicle. A
low voltage power supply is thereby available for the personal LED
warning signal light 730 when used in conjunction with a motor
vehicle. The plug in adaptor 736 may also resemble a power cord for
a cellular telephone thereby hiding the function of the personal
LED warning signal light 730. Alternatively, the personal LED
warning signal light 730 may be powered by one or more batteries
738.
[0433] During use, the personal LED warning signal light 730 may be
withdrawn and opened to expose a first panel 740 and a second panel
742. The first panel 740 and the second panel 742 are joined
together by a hinge 744. Following opening, the plug in adaptor 736
may be engaged to either the first panel 740 or to the second panel
742 and to a cigarette lighter receptacle for the provision of low
voltage power to the personal LED warning signal light 730. The
personal LED warning signal light 730 may then be placed upon the
dashboard 746 of a motor vehicle or held for use as a warning
signal light by undercover law enforcement personnel.
[0434] The first panel 740 and the second panel 742 may each
include a tacky and/or adhesive base 748 which functions to assist
in the retention of the personal LED warning signal light 730 upon
the dashboard 746.
[0435] The personal warning signal 730 may include a frame 830
having a back surface 832. The frame 830 includes a lip 834 which
is adapted for positioning and retention of a transparent protector
836. The transparent protector 836 is water resistant and prevents
water and/or other contamination from adversely affecting the
performance of the LED light sources 732. The frame 830 also
includes a pair of parallel sides 838, hinge side 840, and support
side 842. The support side 842 may be angled to facilitate
positioning upon the dashboard of a vehicle.
[0436] An opaque cover or second panel 742 includes a receiving
ledge 844 which is adapted for nesting and covering engagement
relative to the parallel sides 838 during closure of the second
panel or opaque cover 742 over the transparent protector 836. The
second panel 742 therefore conceals the LED light sources 732
during periods of non-use. The personal warning signal light 730
may also have a first nested closed position and a second open
signaling position as indicated in FIGS. 59 and 60. A switch may
also be provided which is adapted to detect the closure of the
second panel 742 relative to the first panel 740 for termination of
power and illumination of the LED light sources 732. The personal
warning signal light 730 may also include a power saving feature to
prolong the utility and life of internal batteries 738.
[0437] An electrical receiving port having a cover may be placed in
either the support side 842 or the tacky or adhesive base 748. The
electrical receiving port is adapted to receivingly engage a plug
848 of a power cord 850. The power cord 850 may includes an adapter
736 for insertion into the cigarette lighter receiving port.
Alternatively, the plug 848 may be inserted into an electrical
receiving port integral to either the opaque exterior surface 846
and/or frame 830.
[0438] The personal warning signal light 730 includes an internal
controller 50 as earlier described. Alternatively, the personal
warning signal light 730 may include an external programmable
controller. A selector switch may also be provided for activation
of pre-stored and/or programmed light signals for illumination
during use of the personal warning signal light 730.
[0439] The personal warning signal light 730 may be configured in
any shape including, but not necessarily limited to, square,
rectangular, round, and/or oval. A reduced thickness dimension may
be provided following closure of the second panel 742 relative to
the frame 830 for placement in the first nesting closed position.
The second panel 742 also functions to provide for sealing
engagement to the frame 830. The LED light sources 732 are rugged
and shock absorbent facilitating transportation and prolonged
usefulness by an individual.
[0440] Referring to FIGS. 63 and 64 an LED light bar 760 is
disclosed. The LED light bar 760 may be formed of a base 762 which
extends longitudinally, traversing the roof of an emergency
vehicle. The base 762 includes a front face 764 and a rear face
766. Each of the front and rear faces 764, 766 include LED
illumination devices 336, 786 which may be configured similarly to
the modular light support 480 identified and described relative to
FIGS. 31-32. The LED illumination devices 336, 786 along the front
face 764 and rear face 766 are positioned within the interior of
the base 762 and are enclosed therein by a transparent protective
cover 860 to minimize contamination and/or exposure to water. The
transparent protective cover 860 may be placed into sealing
engagement with either the front face 764 and/or rear face 766
through the use of a gasket and/or sealant or any other preferred
mechanical and/or chemical sealing mechanism. The protective cover
860 as engaged to the front face 764 and rear face 766 is formed of
a transparent material such as plastic, and/or glass to provide for
transmission of light from individual LED light sources 336, 786
for observation by an individual.
[0441] As earlier depicted with reference to FIGS. 31 and 32 the
LED light sources 336, 786 may be formed into modular units which
may be regularly spaced along the front face 764 and rear face 766.
The LED light sources 336, 786 integral to the front face 764
and/or rear face 766 are each positioned within a culminator 370,
484 as earlier described. The reflector devices as depicted and
described with reference to FIGS. 37-39 may be incorporated into
modular light supports 480 for utilization along a front face 764
and/or rear face 766 of LED light bar 760. The number of light
emitting diode light sources 336, 786 forming each individual
modular unit 480 may vary. Each modular unit 480 may include
between 2 and 20 LED light sources 336, 786. Each of the LED light
sources 336, 786 is electrically connected to a circuit board 346
having heat sink wells 344 as earlier described in reference to
FIG. 36. The construction of the modular light supports 480 and LED
light sources 336, 786 facilitates ease of color modification and
versatile alternative configurations for light transmission from
the light bar 760. The LED light sources 336, 786 as integral to
the base 762 proximate to the front face 764 and/or rear face 766
may be formed of one or more colors. The modular light supports 480
also may preferably include electrical couplers or connectors 790
as earlier described.
[0442] Each modular light support 480, and/or individual LED light
source 336, 786 is in electrical communication with the controller
50. The controller 50 regulates the illumination of LED light
sources 336, 786 to provide any desired color, pattern, combination
of patterns, and/or types of light signals as earlier identified.
The controller 50 may also preferably regulate the illumination of
modules 480 and/or individual LED light sources 336, 786
independently between the front face 764 and the rear face 766. The
controller 50 may further regulate the individual illumination of
LED light sources 336, 786 within sections and/or sectors along the
front face 764 independently with respect to each other and
independently with respect to the rear face 766. The controller 50
may also regulate the illumination of LED light sources 336, 786 in
any desired individual combination, pattern, or sector, for the
provision of an infinite variety of different types of light
signals. For example, one portion of the front face 764 may
transmit a stroboscopic light signal. Simultaneously and/or
alternatively, another portion or sector of the front face 764 may
transmit a different colored flashing light signal at varying time
intervals. Alternatively, a third portion of the front face 764 may
transmit a third color of a pulsating modulated or variable
lighting effect. The examples illustrated herein are, by no means,
restrictive of the infinite variety of combinations or types of
light signals which may be regulated by the controller 50 during
use of the LED light bar 760.
[0443] The controller 50 is in electrical communication with the
modular light supports 480, LED light sources 336, 786 take-down
lights 700, alley lights 800, 808, and pod illumination devices 770
during use of the LED light bar 760. The controller 50 may
therefore regulate the modular light sources 480, take-down lights
700, alley lights 800, 808, and pod illumination devices 770 either
simultaneously, independently, and/or in combination. Further, the
controller 50 is also in electrical communication with rotational
and/or reflector devices such as earlier described with reference
to the intersection clearing light. The controller 50 may also be
in electrical communication with the reflector as described in
detail with respect to FIG. 47 which may be positioned within the
pod illumination devices 770.
[0444] Light bar 760 includes base 762 which is elevated with
respect to the roof of an emergency vehicle to enhance
visualization during use.
[0445] The LED take-down light 700 and/or alley lights 800, 808 may
be integral to the base 762 proximate to each of the first and
second ends 862, 864 of light bar 760. An end cap 772 may be
secured to the first and second ends 862, 864 of the base 762. Each
end cap 772 encloses the take-down light 700 and alley lights 800,
808. The end caps 772 may be elevated above or alternatively may
rest upon the roof of an emergency vehicle and may assist to
support the longitudinally extending base 762. The end caps 772
provide for visualization of the LED light bar 760 from the sides
of an emergency vehicle. Each end cap 772 may have the same width
dimension as the base 762 or have larger or smaller dimension as
dictated by manufacturing and performance considerations.
[0446] Supports 774 extend angularly upwardly and forwardly from
the base 762 for elevation and of the pod illumination devices 770
above the base 762. The supports 774 preferably are substantially
vertical and are angled inwardly and forwardly toward the front
face 764 of the LED light bar 760. The supports 774 may be formed
of any material provided that the essential functions, features,
and attributes described herein are not sacrificed. The supports
774 are aerodynamically designed to improve the efficiency for the
LED light bar 760.
[0447] Each pod illumination device 770 is elevated by at least one
and preferably two supports 774. The elevation of the pod
illumination devices 770 above the light bar 760 enhances
illumination source differentiation of light signals as observed by
individuals.
[0448] The pod illumination devices 770 may either be circular,
oval, square, rectangular, or any other shape. The pod illumination
devices 770 include LED light sources 336, 786 as earlier
described. The visualization of the LED light bar 760 is enhanced
by the pod illumination device 770 permitting observation at all
angles relative to an emergency vehicle.
[0449] The pod illumination devices 770 include a frame 866
comprised of metal, plastic, rubber, and/or any other sturdy
material. The frame 866 includes a transparent protective cover 868
which functions to prevent moisture or other contamination from
adversely affecting the performance of the LED light source 336,
786. The transparent protective cover 868 is formed of a material
such as plastic or glass to permit light transmission therethrough
during use of the light bar 760.
[0450] Each LED light bar 760 has at least one and preferably two
or more pod illumination devices 770 for the provision of warning
light signals for observation by individuals. Each of the pod
illumination devices 770 are disposed proximate to either the first
end 862 and/or second end 864 of light bar 760. Alternatively, a
pod illumination device may be centrally disposed between the first
end 862 and second end 864 at light bar 760.
[0451] A controller 50 is preferably in electrical communication
with the LED light sources 336, 786 integral to the pod
illumination devices 770 to provide for an infinite variety unique
lighting signals as earlier described. The controller 50 may
independently illuminate the pod illumination devices 770 relative
to each other or provide different light signals within each pod
illumination device 770.
[0452] Each pod illumination device 770 may include individual
columns and rows of multicolored LED light sources 336, 786. Each
individual light emitting diode light source 336, 786 integral to
the pod illumination device 770 may also be enclosed within a
culminator and/or reflector 370, 484 as earlier described having
reflective and/or transparent sections. Alternatively each pod
illumination device 770 may also include a reflector assembly as
illustrated and earlier described within FIG. 47 which includes a
culminator 370, 534 and rotational mechanism or motor 794 as
positioned within the frame 866. The motor 794 provides rotational
or oscillating motion to the reflector 532. Alternatively,
reflector devices as earlier described with reference to FIGS.
37-42, and 44-45 may be incorporated into pod illumination devices
770. The pod illumination devices 770 also may include a frame 866
having a cover or top 874 which is removable to provide access to
either a reflector assembly, culminator, modular light supports 480
and/or LED light sources 336, 786 for repair or replacement
therein. The cover or top 874 may be affixed to the pod
illumination devices 770 by any conventional means including but
not limited to the use of bolts, screws and/or wing nuts.
[0453] Alternatively, the pod illumination devices 770 may include
flexible circuit boards as illustrated and described in FIGS. 4, 5,
and 12. The pod illumination devices 770 and frame 866 provide an
aerodynamic encasement for the LED light sources 336, 786.
Additionally, the LED light sources 336, 786 may be angularly
offset as previously described in reference to FIG. 14 to enhance
visualization of the emitted light signal along a desired line of
sight.
[0454] The LED light bar 760 provides an aesthetically pleasing
visual shape representative of a high technology appearance to
enhance the visualization of a law enforcement vehicle. The LED
light bar 760 includes an aerodynamic design to reduce drag during
use of an emergency vehicle.
[0455] The pod illumination devices 770 may include modular light
supports 480, 606 as earlier described in reference to FIGS. 23-25,
31-32, and 51-58 herein. Alternatively, the light emitting diode
light sources 336, 786 as disposed in pod illumination devices 770
may be configured in any desired shape or panel as earlier
described in reference to FIGS. 4-10, 12, 14, 23-25, 31-32, 34, 35,
and 37-46, herein. The LED light sources 336, 786 may therefore be
replaceable along with a circuit board, or alternatively, the
entire pod illumination device 770 may be replaceable.
[0456] If modular LED light sources 480, 606 are utilized within
pod illumination devices 770 then rotational mechanisms as
described in FIGS. 21, 22, 40-42, 44, 47, 51, 63, and/or 65, may be
utilized individually, exclusively, and/or in combination with
controller 50 to provide a desired rotating and/or oscillating
warning signal light. Alternatively, the module light sources 480,
606 are not required to be utilized in association with a
rotational device where the controller 50 may be exclusively
utilized to selectively illuminate individual and/or combinations
of LED's 336, 786 to provide a desired type of warning light
signal.
[0457] If non-modular light sources 336, 786 are utilized within
pod illumination device 770, then rotational mechanisms as
described in FIGS. 21, 22, 40-42, 44, 47, 51, 63, and 65, may be
utilized individually, exclusively, and/or in combination with a
controller 50 to provide a desired rotating and/or oscillating
warning light signal. Alternatively, the non-modular LED light
sources 336, 786 are not required to be utilized in association
with a rotational device where the controller may be exclusively
utilized to selectively illuminate individual and/or combinations
of LED's 336, 786, to provide a desired type of warning light
signal.
[0458] The LED light bar 760 may be constructed and arranged as a
one piece unit including the base 762, end caps 772, supports 774,
and pod illumination devices 770. Alternatively, the elements of
the base 762, pod illumination devices 770, end caps 772, and
supports 774 may be releasably secured to each other by any desired
affixation mechanism.
[0459] The rotational light signal provided by the LED light bar
760 and particularly the pod illumination devices 770 may be
provided by mechanical rotational elements as earlier described,
mirror rotational elements, and/or a controller 50 for selectively
illuminating individual columns and/or rows of light emitting
diodes 336,786.
[0460] In an alternative embodiment, an LED light support having at
least one LED illumination source may simultaneously produce and
emit a warning light signal and a systematic information transfer
through encrypted/pulsed light or SIT-TEL pulsated light signal,
within the warning light signal where the SIT-TEL pulsed light
signal is not visible to an unaided eye. The SIT-TEL pulsed light
signal functions as a free space carrier of information for
processing by a receiver unit. The SIT-TEL pulsed light signal may
also be used independently and is not required to be incorporated
as a distinguishable component of a warning light signal. In this
instance the SIT-TEL pulsated light signal appears as a continuous
light source.
[0461] Light emitting diodes may be manufactured to emit light at
any wavelength from infrared to visible. Therefore, an infinite
variety of colors of different wavelengths of LED's are available.
LED's also are extremely flexible in the provision of an
instantaneous light signal which minimizes and/or eliminates carry
over illumination after termination of power. For example, the
application of power to a traditional light source frequently
causes electrons to pass through a filament which in turn causes
the temperature of the filament to increase emitting the visible
light. The termination of power to a traditional light source
having a filament does not immediately terminate the provision of
light. A carry over illumination effect continues as the
traditional light source filament cools. The traditional light
source filament therefore is not flexible for receipt of a very
rapid pulsed power supply for transmission of a pulsed light
signal.
[0462] An LED light source however is well adapted to receive a
rapid pulsed power supply for the provision of a pulsed light
signal. In fact, LED's have the capability to pulse thousands of
times per second where the rapid pulses are unobservable to an
unaided human eye. In these instances, the pulsed LED light source
will appear to an individual to be a constant light signal where
the pulses are not recognizable. The flexibility to provide a
pulsed light signal may also be incorporated into and be a
simultaneously non-recognizable portion of a warning light signal.
Previously identified types of warning light signals include, but
are not necessarily limited to, flashing, stroboscopic, modulated,
variable, pulsating, revolving, oscillating, alternating,
sequencing, arrows, characters, and/or any other type of warning
light signal. A dual function light signal may be provided
including an observable warning light signal and secondly a
communication carrier which is not normally observable within the
warning light signal.
[0463] The duty cycle and/or power to be provided to an LED light
source is regulated by a controller which includes a rapid switch
to enable the rapid pulsation of electrical current to the LED
light source, which in turn causes the provision of a pulsating
light. Simultaneously, the controller may also regulate an
observable light signal for illumination in minutes, seconds,
and/or fractions of seconds to provide a desired type of unique
light effect.
[0464] Pulsated light signals may function as a means for free
space communication of information particularly in substitution for
radio frequency transmissions which have been strictly regulated by
the Federal Communications Commission. The FCC has significantly
limited the availability of wavelengths of radio frequency
transmissions and has restricted zones of use of radio frequency
transmissions to eliminate interference issues which may cause a
safety concern to individuals. The accessibility to radio frequency
signaling devices and shortage of available wavelengths of radio
signals necessitates substitute avenues of communication such as
the transmission and reception of pulsated light signals. The use
of pulsed LED air to air light communication signals eliminates the
necessity for expensive cable, wire, and/or fiber optic
communication devices and the corresponding infrastructure
associated with traditional forms of communication.
[0465] No device is known which replaces conventional lighting with
a pulsed light communication device for transfer of information in
a community or residential setting. A need exists for the use of
general lighting replaced by communicating lights which are more
durable, reliable, and fulfill the requirements of the conventional
lighting, while functioning as a communication channel in free
space. The LED SIT-TEL illumination sources 803 may digitally
communicate signals, and the receivers 818 819 enable communication
from device to device through already existing light sources and
systems, i.e., street lights, houses, etc., to create a free flow
of communication using free space throughout the
community/population centers. The SIT-TEL pulsed light signals are
not limited to use with emergency communication. The SIT-TEL LED
illumination sources 803 generally may be formed of solid state
light components capable of high speed switching which are able to
sustain single or multi-plex channels of communication while
appearing as a regular light. The SIT-TEL LED illumination sources
803 thereby fulfill the requirements of conventional and
non-conventional lighting as well as emergency or warning light
systems.
[0466] The SIT-TEL LED pulsed light signal system in general is
formed of an LED support 801 having one or more first LED
illumination devices 803 electrically coupled thereto. The LED
support 801 may be formed in any shape as earlier described. The
LED support 801 may also be stationary and/or secured to a
rotational device 804 805 as earlier described.
[0467] The first LED illumination sources 803 may be comprised of a
single LED which has been selected for transmission of a specific
wavelength of emitted visible or nonvisible light. Each first LED
illumination source 803 may also be positioned to the interior of a
culminator reflector assembly 807 as earlier described.
Alternatively, a stationary and/or rotatable reflector 809 may be
positioned proximate to the first LED illumination source 803 to
reflect a pulsed light signal along a desired line of sight,
vector, and/or path.
[0468] The LED support 801 may alternatively be formed of a
plurality of first LED's 803 having the same or different
wavelengths of emitted visible or nonvisible light. The LED support
801 may also be organized into specific sectors 811 of select first
LED illumination sources 803 of the same or different wavelengths
of visible or non-visible light.
[0469] The LED support 801 and the first LED light sources 803 are
electrically coupled to a power source 813 as regulated through a
controller 815. The power source 813 may be a low voltage, low
current power supply and may include a rechargeable battery capable
of receiving recharge through coupling to a solar energy cell 817.
Other sources of electrical power may be suitable substitutes
herein. The controller 815 regulates and/or modulates the duty
cycle to be exposed to the individual first LED light sources 803
for the creation of a desired type and/or pattern of warning light
signal. The controller 815 also preferably regulates and/or
modulates the duty cycle to be supplied to the individual first LED
illumination sources 803 for the creation of a desired type and/or
pattern of SIT-TEL pulsed light signal. A variable duty cycle may
also be applied to the first LED light sources 803 through the
controller 815 as well as regulation of the type or combination of
distinct types of light signals as earlier described. In addition,
the same types and/or combinations of types of light signals
whether warning light signals and/or SIT-TEL pulsated light
signals, may be provided simultaneously and/or independently of
each other within different sectors 811 of the LED light support
801.
[0470] The LED light support 801 may include an almost infinite
variety of individual first LED light sources 803 as configured in
any combination, sector, color, and/or pattern. A request by an
operator for a particular color or wavelength of LED pulsating or
warning light signal may therefore be provided through the
controller 814 815, which selectively illuminates a desired and
recognizable combination of individual first LED light source 803
wavelengths to provide the composite light signal. The combination
of independent first LED illumination sources 803 by the controller
815 is particularly useful in the creation of white light which may
be formed of a plurality of individual LED light source 803
wavelengths, where each individual first LED light source 803 is an
independent channel of pulsed light. A composite white light signal
may therefore include in excess of 100 channels of independent and
distinct wavelengths of pulsed first LED light sources 803 where
each wavelength of first LED light sources 803 is pulsating at an
approximate rate of 1000 pulses per second. The rapid rate of
pulsation for the first LED light sources 803, produces a
staggering volume of information for receipt by a second controller
827. Naturally, a significant number of second receivers 823 may be
required to receive all transmitted information. It may also be
preferable to have the number of second receivers 823 equal or
exceed the number of wavelength channels utilized by the first LED
illumination sources 803 for transmission of information.
[0471] The LED light support 801 also includes a first receiver 819
which is electrically coupled to a converter 821. The converter 821
is coupled to the controller 815. The first receiver 819 is capable
of recognizing and receiving a SIT-TEL signal which may be
transmitted either as a directional and/or non-directional pulsated
light signal. The operational range for the first receiver 819 and
the first LED illumination sources 803 is dependent upon the
environmental conditions such as humidity, air pressure, air
temperature, and pollution factors. It is anticipated that in good
environmental conditions that the effective operational range of
the first receiver 819 and first LED illumination sources 803 will
exceed one half mile and extend to three miles or more.
[0472] The first receiver 819 is constructed and arranged to
receive SIT-TEL LED pulsed light signals as generated by a second
independent LED illumination source(s) 829 having a recognizable
wavelength. The received SIT-TEL LED pulsated light signal is
converted into a digital signal by a converter 821 for
communication to the controller 815. The controller 815 receives
the converted digital signal for processing and extraction of
transmitted information to respond to an interrogation or
information transmission request. The controller 815 continues to
process the received digital signal for preparation of an
appropriate responsive signal. At the direction of an individual
the controller 815 then communicates the responsive signal to the
converter 821 which in turn converts the responsive signal to a
series of pulses for transmission from the first LED illumination
source 803 as a responsive pulsed SIT-TEL LED optical free space
communication signal.
[0473] The responsive SIT-TEL LED pulsed light signal in turn is
received by a second receiver 823 as coupled to a second converter
825, second controller 827, and second LED illumination device 829.
The second receiver 823, second converter 825, and the second
controller 827 proceed to translate and process the SIT-TEL pulsed
light signal containing communications which originated from the
first controller 815.
[0474] The first controller 815 and the first LED individual light
sources 803 as well as the second controller 827 and second LED
illumination sources 829 are constructed and arranged to regulate
the transmission of an infinite variety of SIT-TEL pulsed LED free
space optical light signals. The types of SIT-TEL LED pulsed
optical light signals may include but are not necessarily limited
to pre-stored characters, numbers, and/or words, and/or terms as
identified by an assigned combination of long or short pulses or
bar code type or form of signal 803.1, 803.2, 803.3, 803.1a,
803.1b, 803.1c, 803.2a, 803.2b, 803.2c, 803.3a, 803.3b, and 803.3c.
(FIGS. 86-87C.) The pulsed LED light signals may be generated so
that each pulsed LED light signal has an identical duration as a
portion of a SIT-TEL communication. Alternatively, the pulsed LED
light signals may have different durations. Any number of pulsed
light signals having the same or different durations may be grouped
into a signal packet. Each packet or combination of signals may be
assigned a character, number, or other information as data within a
memory which may be integral to a controller 815. Individual
packets of grouped pulsed LED SIT-TEL light signals may be combined
into a message, word, and/or character for processing and/or
translation by a second controller 827 for communication of
information to an individual. The first illumination sources 803
and the second illumination sources 829 are constructed and
arranged to emit and/or transmit thousands of pulses of LED light
within a time period of approximately one second. The pulsation
rate for the SIT-TEL LED pulsed light signal is not observable to
the unaided eye. The volume of available combinations of SIT-TEL
LED pulsed light signals within a very short period of time enables
transmission of a significant amount of information subject to
processing via a first or second controller 815, 827.
[0475] The first and second controllers 815, 827 respectively, each
include a memory having stored software and data files for
processing of received SIT-TEL LED pulsed light signals. The memory
and available stored data facilitate the immediate and automatic
recognition of an environmental condition, parameter, or generation
of a pre-stored SIT-TEL pulsed light response. One example of
recognition of an environmental condition or situation is when
information is desired from a source having an interrogating or
second controller 827 which requests through a SIT-TEL pulsed light
signal the identity and/or status of a first controller 815. The
responsive first controller 815 upon receipt of a verified
interrogation SIT-TEL signal request initiates a responsive SIT-TEL
LED pulsed light signal which communicates the identification
and/or other requested information. A second example of recognition
of an environmental condition and/or situation is when a first
receiver 819 encounters a continuously emitted SIT-TEL LED pulsed
light signal which may function as a warning to trigger an audible
or visual alarm to the first controller 815, to minimize safety
risks to individuals.
[0476] A first controller 815 and a second controller 827 each
preferably contain software establishing a recognition or handshake
protocol for acknowledgment, receipt, and transmission of
information optically through free space SIT-TEL LED pulsed light
signals. The handshake protocol initiates upon the first receiver
819 acknowledging being tagged, or receiving an initial pulsed
SIT-TEL LED light signal from a second controller 827. A responsive
signal is then generated by the first controller 815 for
transmission to the second receiver 823. An acknowledgment message
is returned by the second controller 827 to the first receiver 819.
A preselected pattern of acknowledgments are interchanged to verify
readiness for transmission and receipt of desired information
through the transmission of free space pulsed SIT-TEL LED light
signals. Following transmission of the demanded information and/or
data, additional verification and/or acknowledgment transmissions
may occur between the first receiver 819 and the second receiver
823 prior to the termination of contact through the use of a sign
off protocol.
[0477] The first and second receivers 819, 823 are constructed and
arranged to recognize certain wavelengths of incoming pulsed
SIT-TEL LED light signals. The first and second receivers 819, 823
may be constructed of a plurality of photo detectors, photo diodes,
optical transceivers, and/or photo detecting elements to
simultaneously, individually, and/or sequentially receive
transmissions of SIT-TEL LED pulsed light signals of differing
wavelengths. The first and second controllers 815, 827 respectively
may also be coupled to an automatic and/or manual scanner 831 or
dial which may be manipulated to tune into another wavelength of
transmitted SIT-TEL LED pulsed light signals. For example, an
individual observing a predominantly red SIT-TEL LED light signal
who is expecting to receive a transmitted pulsed SIT-TEL LED light
signal may dial and/or tune a first receiver 819 to a red spectrum
wavelength to locate the signal. Similarly, adjustments are
available for other observed colors. The scanning for pulsed
SIT-TEL LED light signals may also be automated by the scanner 831.
The scanner 831 and/or first and second receivers 819, 823 are
constructed and arranged to independently and/or simultaneously
receive directional and/or non-directional pulsed SIT-TEL LED light
signals for transmission and communication of information between
geographically removed LED illumination sources 803, 829.
[0478] The use of a combination and/or independent warning light
signal and/or pulsated light signal is particularly applicable for
use in motor vehicles. The light support 801 may be integral and/or
fixed to a light bar 833 as engaged to a motor vehicle or emergency
vehicle 835. During use of the SIT-TEL communications system, where
information is transmitted upon carrier pulsated free space SIT-TEL
LED light signals, the second receiver 823, second controller 827,
and second LED illumination devices 829 may be integral and/or
attached to the light bar 833. The first receiver 819, first
controller 815, and first LED illumination sources 803 are
preferably integral with and/or affixed to a motor vehicle license
plate 837. The license plate 837 may include a recessed area 839 or
a transmission opening 841 which is adapted to receive the first
receiver 819 and the first LED illumination sources 803. A
transparent cover 843 preferably traverses the recessed area 839
and/or transmission opening 841 to protect the first receiver 819
and first LED illumination sources 803 from contamination during
use of the SIT-TEL pulsated light system. A battery 845 and/or
power connector 847 may be coupled to the first controller 815
which is located upon the non-exterior face of the license plate
837. The battery 845 may be a lithium battery having an approximate
life span of five years or more. Alternatively, the battery 845 may
be rechargeable through the use of solar powered cells or other
electrical source. Further, the power connector 847 may be coupled
to a vehicle electrical system for the provision of power to the
first controller 815, first receiver 819, and first LED
illumination sources 803. The transparent cover 843 is formed of a
sufficiently sturdy transparent material to prevent tampering
and/or disconnection of the first receiver 819 or the first LED
illumination sources 803.
[0479] The first LED illumination sources 803, first controller
815, and first receiver 819 as integral to the license plate 837
are conspicuously positioned upon a motor vehicle which is
potentially subject to interrogation by law enforcement officers
within law enforcement vehicles.
[0480] The first controller 815 may additionally be electrically
connected to a first signaling device 849 which may be attached to
the dashboard of the motor vehicle. (FIG. 81.) Alternatively, the
first signaling device 849 may be wired into a radio for a motor
vehicle. The first signaling device 849 is constructed and arranged
to receive a signal from the first controller 815 during situations
in which the first receiver 819 has detected a traffic warning
message as generated by a SIT-TEL pulsed LED signal emitted from
the second LED illumination devices 829 as generated by a second
controller 827 within a law enforcement vehicle 835. The first
signaling device 849 thereby provides a visual LED signal 1042 to
the occupants of a motor vehicle as to the presence of a police
officer necessitating clearance of a roadway. (FIG. 82.)
Alternatively, the first signaling device 849 may be coupled and/or
electrically connected to the radio of a motor vehicle to provide
an interrupt switch. Activation of the interrupt switch may cause
termination of internal radio or stereo transmissions within a
passenger vehicle. Alternatively, the activation of the interrupt
switch may permit activation of a database having pre-recorded oral
communications for broadcast over a speaker system to orally advise
a passenger of a motor vehicle as to the presence of an emergency
situation necessitating the clearance of a roadway. Alternatively,
during periods when a motor vehicle radio has not been activated,
the first controller 815 may activate the first signaling device
849 to engage a motor vehicle radio for the provision of an audible
warning alarm. The first controller 815 may additionally include
prerecorded voice recognition messages which may be initiated by
the first controller 815 upon receipt of an appropriate signal from
the second LED illumination devices 829. The audible and/or oral
prerecorded signal may advise an occupant of a motor vehicle as to
the presence of an emergency situation through oral communication
as generated over the radio system of the vehicle. The first
signaling device 849 may also emit a verification buzzing or alarm
signal when activated by the first controller 815 to warn an
occupant of a motor vehicle as to the existence of an emergency
situation.
[0481] The first receiver 819 may be formed of a relatively flat
and thin rectangular sensor 851 which may be positioned adjacent to
a window within the interior of a motor vehicle. The first receiver
819 is preferably electrically connected to both the first
controller 815 and the first signaling device 849. The first
receiver 819 is preferably constructed and arranged to receive
pulsed SIT-TEL LED optical signals for transmission to the first
converter 821 for communication to the first controller 815 for
processing. The first receiver 819 may additionally be constructed
and arranged to receive a polarized pulsed SIT-TEL LED light signal
as may be reflecting from the interior windows of a motor vehicle.
The first receiver 819 may be placed at any location about a motor
vehicle and is not limited to affixation to a license plate 837.
The first receiver 819 is preferably placed at a location about a
motor vehicle which is easily accessible to transmitted directional
and/or non-directional pulsed SIT-TEL light emitting diode signals
as generated by the second LED illumination devices 829.
[0482] The second LED illumination device 829, second controller
827, second receiver 823, and second converter 825 are generally
attached or integral to an emergency vehicle such as a police squad
automobile. The second LED illumination device 829 and second
receiver 823 may be attached to a light bar 833 at a central and/or
other convenient location. The second controller 827 may be
positioned to the interior of the light bar 833 or located within
the interior of the emergency vehicle or police squad automobile. A
power supply such as a battery may be integral to the light bar
833. Alternatively, power may be provided to the components of the
second controller 827, second receiver 823, second converter 825,
and second LED illumination devices 829 through the use of a
removable power cord coupled to a receptacle such as a cigarette
lighter, or may be hardwired to the electrical system of the
emergency vehicle. The low voltage requirements for the pulsed
SIT-TEL LED signaling system does not adversely affect the power
parameters for the emergency vehicle. The first signaling device
849 may also include a switch 863 disposed at a convenient location
within the interior of the emergency vehicle for activation of the
pulsed SIT-TEL LED signaling and/or interrogation system. A scanner
865 may also be coupled to the second controller 827 to facilitate
recognition of the wavelength of the pulsed SIT-TEL LED light.
[0483] A selection switch 867 may also be coupled to the second
controller 827 to regulate the emission of focused optics and/or
wide angle directional or non-directional pulsed SIT-TEL LED light
signals from the second LED light sources 829. A wavelength switch
869 may also be coupled to the second controller 827 to enable
adjustment or change to the wavelength of emitted pulsed SIT-TEL
LED light signals. An officer and/or law enforcement personnel may
therefore select from an almost infinite variety of visible and/or
non-visible light signals. The second controller 827 is preferably
additionally electrically connected to a terminal 871 within an
emergency vehicle 835 and/or police squad automobile to visually
generate information observable on a screen or display by an
officer. (FIG. 81.)
[0484] Alternatively, the second LED illumination device 829 and/or
second receiver 823 may alternatively be incorporated into a hand
held unit 852 for use in specific targeting of motor vehicles by
law enforcement personnel. (FIG. 85.) The hand held unit 852
includes a hand grasping portion 854 and a main body portion 856. A
trigger 858 may be included in the handle grasping portion 854. The
trigger 858 enables a law enforcement officer to instantaneously
and selectively activate the generation of a pulsed SIT-TEL LED
light signal from the second LED illumination device 829 to
initiate interrogation of a first controller 815 and first receiver
819. The main body portion 856 includes a forward end 861 which is
the location of the second LED illumination device 829 and second
receiver 823. The second controller 827, second converter 825,
and/or battery 845 may be located in either the main body portion
856 and/or the handle grasping portion 854 dependent upon space
availability considerations.
[0485] Power may be provided to the hand held unit 852 through the
use of a battery, power cord, having an adapter for coupling to a
cigarette lighter receptacle, and/or directly hard wire connected
to the electrical system of a motor vehicle 835.
[0486] The handle grasping portion 854 and/or the main body portion
856 may also include a selection switch 867 and/or wavelength
switch 869 as earlier described. A scanner 865 may also be integral
or connected to the main body portion 856 for identification and
recognition of pulsed SIT-TEL LED light signals to be received by
the receiver 823. The hand held unit 852 and second LED
illumination devices 829 may also generate focused optics and/or a
wide angle directional or non-directional pulsed SIT-TEL LED light
signals within the visible or non-visible spectrum. The hand held
unit 852 is also electrically connected to a terminal 871 within an
emergency vehicle 835 and/or police squad to visually generate
information observable on a screen by an officer.
[0487] The features as earlier identified for the pulsed SIT-TEL
LED light signal system as integral to a light bar 833 and/or hand
held unit 852 are equally applicable to a stationary unit 873. It
is anticipated that a stationary unit 873 is releasably mounted to
a dashboard of an emergency vehicle through the use of brackets
875. The stationary unit 873 may be provided with or without a hand
grasping portion 854. In one embodiment a handle grasping portion
854 may also be omitted and/or eliminated where the trigger 858,
switch 863, select switch 867, and/or wavelength switch 869 are
preferably located on the main body portion 856, at a location
convenient for manipulation by an officer. A scanner 865 as earlier
described may also be integral or releasably coupled to the
stationary unit 873. The stationary unit 873 has the capability and
flexibility to recognize and emit an almost infinite variety of
pulsed SIT-TEL LED light signals. Further, the stationary unit 873
may also be connected and/or releasably coupled to a terminal 871
integral to an emergency vehicle 835 for a visual display of
information representative of translated received pulsed SIT-TEL
LED light signals.
[0488] The license plate 837 and SIT-TEL signaling system may be
encapsulated within a protective cover. Alternatively, the rear
face of the license plate 837 may be encapsulated to protect the
first controller 815, first receiver 819, and first LED
illumination sources 803 from damages caused by undesirable
moisture, dirt, dust, and/or other foreign particles.
[0489] The rapid pulsation of electrical energy through the first
LED light sources 803 potentially may generate undesirable
excessive heat. A heat sink for the license plate 837 is generally
not required because the duration of illumination of a pulsed
SIT-TEL LED light signal, is anticipated to be sufficiently short,
to avoid the build-up of excessive undesirable heat. Alternatively,
the license plate 837 and/or light support 801 may function as a
heat sink to dissipate heat generated by the first LED light
sources 803, during illumination of a pulsed SIT-TEL LED light
signal.
[0490] The first LED light sources 803 and the second LED light
sources 829 are preferably positioned within a culminator and/or a
reflector 807 as earlier described. The angle of the interior face
of the culminator 807 relative to horizontal, and/or the angle of
the reflective face of the reflector 807 relative to horizontal
generally imparts a desired amount of focus for the generated
pulsed SIT-TEL light signal. The focus of the generated pulsed LED
light signal is also impacted by the wavelength selected to be
illuminated by the controllers 815, 827 respectively.
[0491] A SIT-TEL pulsed light signal is used independently and/or
in combination with an observable warning light signal to
supplement awareness of an emergency situation. Law enforcement
and/or emergency vehicles 835 frequently utilize sirens to warn
motorists as to the existence of an emergency situation. Sirens of
the past have increased in decibel volume through increases in
applied power. In the past, sirens have been operated by
application of approximately 68 watts of power. The amount of power
to sirens has significantly increased to 200 to 400 watts. The
significant increase in power applied to sirens has been partially
in response to the manufacture of quieter automobile interiors
which has significantly reduced the volume of exterior road noise.
In addition, automotive stereo systems have significantly improved,
further reducing a motor vehicle occupants ability to hear an
emergency siren. Siren volume has therefore increased to a point
where unprotected hearing to individuals may cause injury. It is
anticipated that the volume of sirens may be required to be reduced
necessitating alternative avenues of communication of information
related to the existence of an emergency situation. One solution to
improve the recognition of the existence of an emergency situation
is to position a first receiver 819 within the interior of a
vehicle. The location of the first receiver 819 is not critical due
to the reflection of the pulsed SIT-TEL LED light signal off the
interior windows which will strike the first receiver 819.
[0492] It is anticipated that a pulsed SIT-TEL LED light signal may
be used in any number of activities to facilitate the performance
of law enforcement or emergency duties. The SIT-TEL LED pulsed
light signal communication system may be used as an interrogation
device upon a targeted motor vehicle. A law enforcement second LED
illumination device 829 may be activated via a switch 863 and/or
trigger 858 to generate a first SIT-TEL LED pulsed light signal to
be received by the first receiver 819 as integral to a license
plate 837 and/or located within a motor vehicle. (FIGS. 69-70.) The
targeted first receiver 819 then preferably generates an electrical
signal to the first converter 821 for transfer to the first
controller 815. A responsive message is generated by the first
controller 815 for transmission by the first LED illumination
sources 803. The responsive pulsed light signal will include a
recognizable pattern of pulsed SIT-TEL LED light which may not be
observable by the unaided eye. The responsive pulsed SIT-TEL LED
light signal will therefore transfer basic information such as
make, model, license plate number, status of license tab
registrations, driving after revocation, and/or expiration of
insurance, for a tagged and/or interrogated motor vehicle. The
responsive SIT-TEL signal received by the second receiver 823 of
the law enforcement vehicle will be processed by the second
controller 827 for coupling to a database and/or microprocessor
integral to a terminal 871 within a police vehicle 835. Data
therefore may be instantaneously retrieved for display to law
enforcement personnel related to the likely occupant and/or
criminal and/or driving record of the tagged vehicle without the
necessity for an officer to close distance to the suspect vehicle
to permit unaided observation of the license plate 837. The speed
and ease of access to Department of Motor Vehicle information to
aid an officer is therefore significantly enhanced permitting an
officer to maintain a desired distance from the targeted vehicle.
The use of a pulsed SIT-TEL LED light signal as free space carrier
of information eliminates the necessity for a law enforcement
vehicle to expend significant economic resources for costly optical
aids. The selection of directional or non-directional pulsed
SIT-TEL LED signals also permits a law enforcement vehicle to
interrogate a significant number and/or virtually all motor
vehicles on a roadway to search for a stolen car and/or abduction
where time is of the essence to insure safety to an individual. In
addition, a passive search may be activated for the pulsed SIT-TEL
light communication system to attempt to identify any motor
vehicles within a particular class. The electric coupling to a
processor integral to a law enforcement vehicle enables an officer
to access a database to check for outstanding warrants for an
individual. If information is received concerning an individual
which would raise a safety concern for the law enforcement
personnel then sufficient time is provided to immediately request
backup prior to the initiation of a motor vehicle stop.
[0493] The pulsed SIT-TEL LED illumination system may also be used
to enhance positioning and/or mapping of a travel route for an
emergency vehicle 835 by periodic verification of position locators
within a geographic area. This feature may be particularly useful
in fire safety applications. The pulsed SIT-TEL LED illumination
system also provides to law enforcement personnel immediate
verification that a correct vehicle has been tagged for
interrogation through the issuance of a responsive pulsed SIT-TEL
LED light signal for transmission to and receipt by the second
receiver 823. The accuracy of law enforcement activities is thereby
significantly improved.
[0494] The pulsed SIT-TEL LED light signal may also be used as
optical pulses to be received by a first receiver 819 to enter a
security code for access to a gated community, garage, and/or
secure parking lot. In these instances, the second LED illumination
sources 829 generate a pulsed SIT-TEL LED light signal for receipt
by the first receiver 819 which in turn is coupled to a first
controller 815 and a switch to open an otherwise locked gate. The
pulsed SIT-TEL LED light signal may also be used by law enforcement
and/or highway personnel to modify illuminated highway signs. A
second LED light source 829 may generate a coded signal for
modification of a stationary illuminated street sign for display of
a new message.
[0495] The first and second controllers 815, 827, preferably
decipher a digitized received pulsed light signal so that
appropriate action may be initiated. Further, the pulsed LED
lighting system may be used to verify speed and/or separation
distance from a stationary second light emitting diode illumination
source 829 and second receiver 823.
[0496] In an alternative embodiment, a wide angle passive pulsed
second SIT-TEL LED illumination signal 829 may interrogate an
automobile for return of abbreviated and/or select information such
as expired license plate tabs. The initial pulsed SIT-TEL LED light
signal may therefore be constructed and arranged to request the
provision of specific information related to a motor vehicle.
[0497] In an alternative embodiment, the first controller 815 may
be electrically coupled to a motor vehicle speedometer. If the
motor vehicle exceeds a certain pre-stored speed then the first
controller 815 may signal the first LED illumination sources 803 to
initially generate an excessive speed signal to be received by a
second receiver 823 integral to a law enforcement vehicle 835.
[0498] Transportation markers such as road signs and/or mileage
signs may include a pulsed SIT-TEL LED signaling device to
communicate information to a motor vehicle particularly with
respect to location or road detour routes.
[0499] The pulsed SIT-TEL LED light signaling system may also be
incorporated into aircraft. (FIG. 71.) A necessity exists for use
of the pulsed SIT-TEL LED light signaling system in an aircraft due
to the shortage of available radio frequencies and the problems
associated with radio frequency communication saturation in air
traffic control zones and air traffic interference in controlled
air zones. Further, radio interference between geographic areas
provides incomplete availability or protection during use of radio
frequency air warning systems.
[0500] Aircraft anti-collision warning systems are extremely
important for pilot and civilian safety. A need exists to
supplement known aircraft anti-collision systems with durable, low
voltage, and efficient pulsed optic warning systems which are not
dependent upon radio frequency communications signals. Some
aircraft include transponders for use in anti-collision systems
and/or TCAS systems within transponders zones proximate to an
airport. Other aircraft may pass through regulated transponder
zones where the aircraft does not include anti-collision
transponders. The risk of air collision within restricted
transponder zones is increased by the existence of non-transponder
aircraft. A supplemental air anti-collision warning system is
therefore needed especially where the supplemental air
anti-collision warning system may be incorporated into the existing
aircraft lighting systems at an insignificantly increased
incremental expense.
[0501] In the past, there has generally been two different versions
of TCAS where the first version indicates the bearing and relative
altitude of an aircraft within a selected range of approximately 10
to 20 miles of another transponder equipped aircraft. Within this
first TCAS system a traffic advisory may be issued to identify the
intruding aircraft which may permit the increase or decrease of a
planes altitude by up to approximately 300 feet. The initial TCAS
system does not provide solutions for air anti-collision avoidance,
however, the TCAS initial system provides pilots with important
information to initiate a course of action to avoid collision. In a
second version of TCAS, a pilot is provided with resolution
advisories. This TCAS system determines the course of each aircraft
and whether the aircraft is climbing, descending, or flying
straight and level. The enhanced TCAS system issues resolution
advisories to pilots to execute types of evasive maneuvering
necessary to avoid collision. If both aircraft are equipped with
the enhanced TCAS system, then the two computers on the respective
aircraft offer the conflicting resolution advisories. The
non-conflicting resolution advisories prevent course alternations
which would effectively cancel anti-collision corrections between
the two aircraft which would result in a continued threat.
[0502] In the past, aircraft emergency location warning signal
systems have been extremely dependent upon the electrical power
system of the aircraft. In the event of a power interruption, an
emergency locator beacon frequently became inoperable or was
required to operate from a limited power source as provided from
the aircraft battery. The emergency locator visual beacons of the
past frequently required relatively large amounts of current which
depleted available battery resources in a short duration of time. A
need therefore exists for an emergency locator beacon which is
durable and which draws a significantly reduced amount of current
to provide extended periods of illumination when the main power
source for an aircraft is not available. In addition, an emergency
locator beacon for an aircraft is needed where the power source may
be rechargeable through the use of solar energy.
[0503] The pulsated SIT-TEL LED signaling light system may be
incorporated into an aircraft 876. Generally, the pulsated SIT-TEL
LED signaling light system will originate from a rotating or
flashing beacon 878, which is secured to the exterior of the
fuselage of the aircraft 876. The beacon 878, may be fixedly
positioned relative to the fuselage and/or adjustably
repositionable thereon. Certain aircraft 876, may utilize one or
more beacons 878, within the pulsed SIT-TEL LED signaling system.
Each beacon 878, is formed of a light support 801, and first LED
illumination sources 803, as earlier described. In addition, the
first LED illumination sources 803, may be positioned within a
stationary panel or may be incorporated within a rotational device
805, as earlier described. Each first LED illumination source 803,
is placed within a culminator assembly 807, as earlier described.
In the event that a stationary LED light support 801 is utilized
within the beacon 878, then a rotatable reflector assembly 809, may
be positioned over and/or adjacent to the LED light support 801, to
facilitate the appearance of rotation. Alternatively, the LED
illumination sources 803, may be selectively illuminated by the
first controller 815, to provide and impart the appearance of
rotation for the beacon 878. The LED light support 801, may be
organized into sectors 811, of individual LED illumination sources
803, having different wavelengths of emitted light as earlier
described.
[0504] The beacon 878, used in conjunction with an aircraft 876, is
a replacement illumination source which provides the additional
feature of a pulsed SIT-TEL LED optical signaling system which may
be generated at the same time as the emission of a visible light
signal from the beacon 878. The beacon 878, may therefore,
incorporate dual functionality of a visible illumination source and
a nonvisible pulsed signaling system for transmission of
information between the first LED illumination sources 803, and a
second removed receiver 823.
[0505] The LED light support 801, as used as a component of the
beacon 878, may preferably be cylindrical, octagonal, hexagonal,
square, rectangular, and/or oval. In addition, the LED light
support 801, may be formed of flexible circuit boards as earlier
described herein. The first LED illumination sources 803, may be
formed of an infinite variety of colors and/or wavelength patterns
to facilitate transmission of pulsed SIT-TEL LED light signals. The
beacon 878, may also incorporate a strobe illumination source 880,
which functions as an anti-collision warning light signal for an
aircraft 876. The beacon 878, strobe warning light 880, first LED
illumination sources 803, and any rotational device 805, are in
communication with the first controller 815, which is constructed
and arranged to provide modulated light intensity to the first LED
illumination sources 803. The modulated light intensity is provided
to the first LED illumination sources 803, may increase or decrease
the voltage or duty cycle applied to brighten or dim illumination
from the beacon 878, at a predetermined rate. Additionally, the
first controller 815, regulates the rate of pulsation of the first
LED illumination sources 803, during the generation of a pulsed
SIT-TEL LED light signal.
[0506] The beacon 878, and/or strobe light signal 880, is designed
to supplement and/or replace existing aircraft lighting systems by
substituting LED technology for conventional lighting sources. The
first controller 815 is constructed and arranged to continue to
offer enhanced light signals and/or any other desired type of
lighting signal for use in association with an aircraft 876.
[0507] Enhanced flexibility is provided to an aircraft 876,
lighting system through the adjustment of the duration of the duty
cycle for the first LED illumination sources 803 for a pulsation
rate which was previously unavailable and unknown for use in
association with aircraft 876, and conventional light sources.
[0508] Traditionally, the beacon 878, emits a light source having a
red wavelength. The port wing of an aircraft 876, also
traditionally emits a red light source. The starboard wing of an
aircraft 876, traditionally emits a green light source. The
fuselage of an aircraft 876, traditionally emits a white light
source. A white light source is generally utilized for landing,
ground, and/or taxi lights for an aircraft 876. The port and
starboard wing, fuselage, and landing, ground, and/or taxi lights
may be LED illumination sources 803, which in turn may be utilized
as a portion of the pulsated SIT-TEL LED signaling system for an
aircraft 876. In addition, the beacon 878, strobe, port and
starboard wings, fuselage, landing, taxi, and/or ground lights may
be incorporated within filters and/or other devices to emit a
polarized directional optical light signal.
[0509] The pulsated light signals as emitted from the first LED
illumination sources 803, and regulated by the first controller
815, may be either encoded and/or encrypted for receipt by the
second receiver 823, located at a remote position relative to the
aircraft 876. The pulsed SIT-TEL LED illumination signals as
generated by the first LED illumination sources 803, communicate
information as to the identity of the aircraft 876, and/or the
position of an aircraft 876, relative to an obstacle and/or
tower.
[0510] Generally, an observable light signal may be generated from
the first LED illumination sources 803, as an anti-collision light
source, at a rate of 20 to 60 cycles per minute. A non-observable
pulsated light source may be generated by the first LED
illumination signals 803, at a rate of 80 hertz and preferably 100
hertz or greater. The pulsed SIT-TEL LED light signal as
transmitted by the first LED illumination sources 803, may be
prerecorded, processed, and/or converted in real time where a
combination of pulsed sequences represents characters, words,
and/or numerals for communication of information via a pulsed light
signal.
[0511] An operator may select from a number of pre-stored pulsed
light combinations representative of information to be communicated
via the first controller 815. Alternatively, real time
communications may be transmitted by pulsed light signal via the
use of a keyboard or voice activated system where the controller
815, translates the information into combinations of pulsed light
signals for transmission to a second receiver 823. A second
receiver 823, preferably receives the generated pulsed LED signals
for initial processing and for transfer to a second controller 827,
for communication to an individual or system.
[0512] The first controller 815 is also constructed and arranged to
continue communication of pulsed light signals containing
information such as call sign, type, destination, flight plan,
and/or other pre-programmed information following an incident or
mishap for an aircraft 876.
[0513] The first controller 815, is programmed to include a
sufficient level of sophistication to eliminate recognition of
false light signals which may occur from a source such as sunlight
in analyzing and transmitting pulsed LED light signals. The
controller 815 may also include a handshake protocol to assist in
recognition of a pulsed SIT-TEL LED light signal. The handshake
protocol may include an alternating pre-set pattern of ultra high
speed pulsating SIT-TEL LED light signals of the same or different
wavelengths as may be transmitted in a pre-determined and
recognizable combination prior to the transmission of information
between a first controller 815, and a second receiver 823. The
second controller 827, is preferably constructed and arranged to
search for and focus upon pre-set patterns of pulsed SIT-TEL LED
illumination signals to finalize the handshake recognition protocol
for elimination of interference light signals. The controller 815,
may also include any number of filters which may be manipulated by
a pilot for attachment to the first receiver 819, for elimination
of undesirable light signals.
[0514] The pulsed LED signaling light system for use in association
with an aircraft 876, preferably augments any available TCAS
system. All aircraft may be conveniently converted for generation
of a pulsed SIT-TEL LED light signal. The wavelength emitted in
association with the pulsed SIT-TEL LED light signal may be in the
visible and/or non-visible spectrum and include wavelengths in the
infrared and ultra-violet regions. Further, the pulsed SIT-TEL LED
signaling light system may function as a backup to radio frequency
transmissions utilized for anti-collision warnings. The pulsed
SIT-TEL LED signaling light system in association with an aircraft
876, fulfills FAA requirements of aircraft identification and
collision avoidance and may continuously optically transmit a
required light signal while simultaneously communicating
information and/or a message within an encoded pulsed SIT-TEL LED
light signal.
[0515] The pulsed SIT-TEL LED light signal system may also be used
in an airport air traffic environment for VFR pattern verification
and control. The pulsed SIT-TEL LED signal light system may
additionally function as a backup to the transponder of the
anti-collision TCAS system.
[0516] The pulsed SIT-TEL LED signal light system in association
with an aircraft 876, may be utilized to verify position, provide
aircraft identification and guidance, act as a proximity warning or
anti-collision indicator while simultaneously providing
illumination as a rotating beacon, obstruction illumination and
clearance light, taxi or ground lights, and/or wing or fuselage
illumination sources.
[0517] The first controller 815, is positioned onboard proximate to
the control panel of an aircraft 876, for regulation and
transmission of information and/or data via the first LED
illumination sources 803. The controller 815, receives converted
pulsed SIT-TEL LED light signals for processing to communicate
information to a pilot and/or air traffic controller. The
controller 815 preferably regulates the transmission of data via
pulsed SIT-TEL LED light signals for transmission to other aircraft
and/or tower optical receivers 823. The initiation of the pulsed
SIT-TEL LED signaling light system may occur at any time as
selected by a pilot. Alternatively, the emission of pulsed SIT-TEL
LED light signals may be continuous.
[0518] The LED support 801, as used within the stationary beacon
878, may include any number of individual first LED illumination
sources 803, each having a different wavelength. Within the LED
support 801, individual first LED illumination sources 803, may be
collected within a specific region and/or sector 811 and controlled
as a group by the controller 815. Any number of collections,
groups, and/or sectors 810 811 of first LED illumination sources
803 may be provided where each collection, group, and/or sector 811
is constructed and arranged to provide either a different and
distinct warning light signal and/or a different and distinct
pulsed SIT-TEL LED light signal. In addition, the controller 815,
is preferably constructed and arranged to selectively illuminate
individual first LED illumination sources 803, and/or different
sectors 811 for the provision of any desired combination of warning
light signals and/or pulsed SIT-TEL LED light signals. The
controller 815, may therefore transmit more than a single warning
light signal and more than one pulsed SIT-TEL LED light signal
simultaneously.
[0519] A second aircraft 882, and/or ground location 884, may have
one or more second receivers 823, where one of said second
receivers 823, is constructed and arranged to receive a SIT-TEL
light signal as generated from each group and/or sector 811 of
LED's 803. A second receiver 823, and second controller 827, may be
constructed and arranged to simultaneously receive any number of
transmitted pulsed SIT-TEL LED light signals. The second controller
827, is constructed and arranged to collate, decode, translate, and
organize the simultaneously received pulsed SIT-TEL LED light
signals into a composite decoded message.
[0520] The speed of transmission and receipt of pulsed SIT-TEL LED
light signals enables messages to be encrypted to provide for the
secure transmission of information for receipt by a ground location
884, and/or second aircraft 882. The speed of pulsed SIT-TEL LED
light signals may exceed two kilohertz. The most readily apparent
limitation on the transmission of encrypted messages relates to the
size of the one or more second receivers 823, for receipt of
encrypted pulsed SIT-TEL LED light signals. The second controller
827, may also include any desired passwords or verification
messages to insure the validity of receipt of secure transmissions.
Communication of pulsed LED light signals may be terminated by a
first controller 815, at any time when an initial and/or periodic
required responsive pulsed SIT-TEL LED light signal is not received
by the first receiver 819, and/or the accuracy of the received
SIT-TEL LED light signal is not verifiable.
[0521] Any number of first controllers 815, and/or second
controllers 827, may be interconnected and/or coupled for
transmission and receipt of pulsed SIT-TEL LED light signals.
Further, independent controllers 815, and/or 827, may be assigned
to transmit and/or translate a portion of a composite pulsed
SIT-TEL LED light signal. Security is thereby enhanced due to the
partial receipt of a secure transmission by an individual
controller 815, 827.
[0522] The second receivers 823, may be assembled in any array
integral to a support 801, and/or removably positioned therefrom.
In one embodiment, a circular and/or octagonal array, may be
proximate to, or integral with, the light support 801. Each array
includes at least one second receiver 823, on each face of the
octagonal array. Alternatively, a plurality of second receivers
823, may be adjacent to each other about the circumference of a
circular array.
[0523] Each array of second receivers 823 is interfaced within an
aircraft 876 TCAS anti-collision system for detection of pulsed
SIT-TEL LED light signals. It is desirable to determine whether a
transmitted pulsed SIT-TEL LED light signal is occurring in a
crossing direction relative to the array, where the transmitted
SIT-TEL LED light signal is sequentially detected and/or tracked by
adjacent second receivers 823. If sequential detection by the
second receivers 823, occurs, then a second aircraft 882, is
pursuing a crossing pattern relative to the first aircraft 876,
minimizing risk of collision. Alternatively, if a single second
receiver 823, or group of receivers 823, continuously receives a
pulsed SIT-TEL LED light signal and no sequential tracking is
detected, then it is likely that the second aircraft 882, is on a
constant bearing decreasing range course necessitating an
anti-collision warning. A visual and/or audible alarm may be
provided by the second controller 827, in the event that the second
receivers 823, and/or group of second receivers 823, continuously
receive a transmitted SIT-TEL LED pulsed light signal for a period
of time exceeding approximately three to five seconds. The second
controller 827, may be programmed to include any desired period of
time as a threshold prior to triggering of the visual and/or audio
warning within the aircraft TCAS system advising of a constant
bearing decelerating range second aircraft 882.
[0524] The second controller 827, may include wavelength selection
devices such as dials and/or scanners 831 to continuously search
for transmitted pulsed SIT-TEL LED light signals. Alternatively,
the second controller 827, may be coupled to a key pad 888, which
may be used by a pilot to select an individual wavelength for a
pulsed SIT-TEL LED light signal. (FIG. 84.) Alternatively, each of
the second receivers 823, may be sensitive for receipt of pulsed
SIT-TEL LED light signals having different wavelengths. The second
receivers 823, preferably are flexible to receive a pulsed SIT-TEL
LED light signal whether wavelength specific and/or source
sensitive.
[0525] The alarm 890, triggered by the second controller 827, may
advise a pilot by reciting terms such as "warning" and may further
provide a direction of the received signal to initiate
investigation to avoid collision. In this embodiment, the
individual second receivers 823, are each associated with a
pre-stored site within the second controller 827. The receipt of a
pulsed SIT-TEL LED light signal may therefore be traced by the
second controller 827, to a second receiver site 823, to indicate
the general direction of the source of the pulsed SIT-TEL LED light
signal to enhance investigation by a pilot. Each second receiver
823, may be assigned a different site especially when two or more
arrays, are utilized on an aircraft 876.
[0526] In general, the beacon 878, strobe light source 880, and/or
aircraft lighting system receive power from the main power source
for an aircraft. In addition, the beacon 878, strobe light source
880, and/or aircraft lighting system may be coupled to a backup
battery or power source, transported within the interior of the
aircraft 876. The backup battery source, may additionally include a
rechargeable feature through the use of a solar power cell.
[0527] In the event of an emergency survival situation frequently
the main power supply for an aircraft 876, is unavailable to
provide power to a beacon 878, position lights, strobe 880, and/or
aircraft lighting system. In this instance the battery for the
aircraft may be utilized to provide power to the LED beacon 878,
strobe 880, and/or aircraft lighting system to continue to provide
illumination to identify the coordinates and/or location of the
aircraft 876. The reduced power and/or current requirements for the
LED beacon 878, position lights, strobe 880, and/or aircraft
lighting system prolong the useful life of the aircraft battery to
approximately two to three days. A backup battery transported
within the interior of the aircraft 876, may then be coupled to the
beacon 878, strobe 880, and/or aircraft lighting system to provide
power once the main aircraft battery has been depleted. The backup
battery is then anticipated to provide power to the beacon 878,
strobe 880, and/or aircraft lighting system for an additional
period of time of approximately two to three days prior to
recharge. The inclusion of a solar cell may enable continuous
recharge of the second battery for provision of power to the beacon
878, strobe 880, and/or aircraft lighting system.
[0528] The rotating beacon 878, strobe 880, and/or aircraft
lighting system may be encased within waterproof enclosures to
facilitate continuous operation in adverse conditions. In addition,
the beacon 878, strobe 880, and/or aircraft lighting system may
further be coupled to an accelerometer which senses aircraft 876,
deceleration rates beyond expected parameters. An accelerometer
activates the emergency beacon and may initiate a pulsed SIT-TEL
LED light signal of preprogrammed information related to aircraft
call sign, type of craft, and destination once an unacceptable
deceleration rate is detected. The transmission of pulsed SIT-TEL
LED light signals thereby augments the current emergency locator
transmitter signals for identification of the location of a downed
aircraft 876.
[0529] The systematic information transfer through encrypted/pulsed
light (SIT-TEL) system may also be incorporated into an airport
tower 894, and/or obstacle 896, such as a power line support tower
and/or radio tower. In the past radio and/or power line towers have
used rotating red light beacons having traditional illumination
elements such as halogen lamps and/or gaseous discharge xenon lamps
to warn air traffic. Power is generally provided to the rotating
beacons through a hardwired electrical source. In the past, the
traditional illumination sources have not included a long life
span, have required large amounts of power to operate, and have
been difficult to maintain. In addition, the rotating warning
beacons as known frequently did not have a backup power supply in
the event of power interruption such as may occur during or
immediately following a storm.
[0530] The systematic information transfer through encrypted/pulsed
light (SIT-TEL) system as engaged to an airport tower 894, and/or
obstacle 896, is formed of a light support 801, having first LED
illumination elements 803, as earlier described. The light support
801, may be attached to a rotational device 805 for rotation where
the light support may include rotational reflectors 809, as earlier
described. Alternatively, a controller 814 815, may provide
modulated light intensity in association with selective
illumination of first LED light sources 803, to generate the
appearance of rotation.
[0531] The SIT-TEL system as engaged to either an obstacle 896,
and/or a tower 894, may therefore provide a warning light signal, a
plurality of singular and/or combination of warning light signals,
and/or a plurality of independent and/or simultaneously pulsed
light signals at different wavelengths for transmission and
communication of information to an aircraft 876.
[0532] The SIT-TEL system as engaged to an airport tower 894,
and/or to an obstacle 896, such as a radio tower may be hardwired
to a suitable power source. In addition, the SIT-TEL system may
include a backup power supply such as a battery.
[0533] The SIT-TEL signal as generated from a tower 896 and/or
obstacle 896 may carry signals representative of characters,
numerals, and/or words in a free space transmission. The generated
pulsed SIT-TEL signals may be utilized for aircraft identification,
anti-collision warnings, relay atmospheric conditions, aircraft
guidance, and illumination. Generally, the SIT-TEL light sources
utilized in association with a tower 894, and/or obstacle 896, are
red in color relating to a preselected wavelength in accordance
with FAA regulations.
[0534] The controller 827, as included within an aircraft 876, may
include voice recognition/activation software which may interpret
received digital impulses for conversion to audible voice messages
to be emitted from a speaker integral to the cockpit. The
controller 827, preferably interprets pulsed LED light signals
received from the second receiver 823, for transmission of alarms
such as noises, lights, and/or voices to a pilot related to air
obstacles 896.
[0535] An aircraft 876, may further include the second LED
illumination sources 829, for transmission of the SIT-TEL light
signals to the first receiver 819, integral to the obstacle 896,
and/or tower 894. The first controller 815, may receive and process
a reply message from the second controller 827, to record data such
as the aircraft identification, time, and date. In addition, the
plurality of first receivers 819, set at different wavelengths may
be used. The modulated reduced duty cycle at certain LED
wavelengths may function as a distance indicator relative to the
obstacle 896. For example, a first wavelength may be selected where
a successful handshake protocol between the first LED illumination
sources 803, and the second receivers 823, and the return signal
from the second LED illumination sources 829, for receipt at the
first receivers 819, indicate an approximate first distance of
three miles between the aircraft 876, and the obstacle 896. A
selected different wavelength emitted from the first LED
illumination sources 803 at a reduced modulated duty cycle as
regulated by controller 815, may be recognized by the second
receivers 823, only when the distance between the obstacle 896, and
the aircraft 876, has been reduced to a distance of two miles or
less. The successful handshake protocol related to the second
wavelength emitted by the first LED illumination sources 803,
indicates that the aircraft 876, has closed distance with respect
to the obstacle 896, by approximately one mile. Additionally, many
features may be included within successive wavelengths to warn the
second controller 827, and aircraft 876, as to the proximity to a
hazard and/or obstacle 896. The warnings may be audible alarms,
visual LED lights, and/or voice signals. A number of wavelengths
may be selected for emission from the first LED illumination
sources 803, and modulated and successively reduced duty cycle to
function as distance indicators relative to an obstacle 896. In
addition, for each successive pulsed LED light signal at a specific
wavelength having reduced duty cycle, the warning message included
within the pulsed LED light signal may incrementally escalate. For
example, the three mile warning may be relatively passive. The two
mile warning may be more severe in flashing lights and buzzing
audible signals. The two mile warning may also transmit to a pilot
harassing warning signals and the one mile warning may be quite
obnoxious. In addition, each successive wavelength having reduced
modulated duty cycle intensity for the first LED illumination
sources 803, may be set at a different repetitive cycle. For
example, the three mile warning signal may repeat every 15 seconds.
The two mile warning signal may repeat every seven seconds, and the
one mile warning signal may continuously repeat.
[0536] The first controller 815, may be programmed to receive a
first handshake protocol related to the three mile pulsed LED
signal. The first controller 815, may then trigger the initiation
of the second reduced modulated duty cycle wavelength LED light
signal from an alternative sector 811 as compared to the first LED
warning light sources 803, within the support 801, corresponding to
the two mile warning. The controller 815, upon recognition of a
second handshake protocol related to the second wavelength may then
initiate transmission of the third reduced modulated duty cycle
wavelength LED light signal from another alternative sector 811 of
the first LED light sources 803 within the support 801,
corresponding to the one mile warning.
[0537] The method for warning an aircraft 876 as to the existence
of an obstacle 896, may initiate by the continuous emission of a
first warning pulsed LED light signal at a first wavelength from a
sector 811 or portion of an LED light support 801, by the first LED
illumination sources 803 integral to the obstacle 896.
[0538] The first warning pulsed LED light signal is received by the
second receivers 823, integral to an aircraft 876, where the second
controller 827, upon receipt of the first warning pulsed LED light
signal at the first wavelength initiates transmission of a first
responsive pulsed LED light signal at the first wavelength to be
received by the first receivers 819, of the obstacle 896.
[0539] The first controller 815, connected to the first receivers
819, upon receipt of the first responsive pulsed LED light signal
continues to transmit at a regular interval the first warning
pulsed LED light signal at the first wavelength. In addition, the
first controller 815, generates continued recognition signals by
issuance of a first acknowledgment pulsed LED light signal for
receipt by the second receivers 823, integral to the aircraft 876.
In addition, the first controller 815, may initiate the
transmission of a second warning pulsed LED light signal at a
second modulated reduced duty cycle and second wavelength, from a
different sector 811, or portion of LED support 801.
[0540] At such time as aircraft 876, has closed to a distance
sufficient to detect the second warning pulsed LED signal by a
second set of second receivers 823, the second controller 827,
initiates transmission of a second responsive pulsed LED light
signal at the second wavelength to be received by another set of
first receivers 819.
[0541] The alternate set of first receivers 819, may then detect
the second responsive pulsed LED light signal from the second
controller 827. The first controller 815, continues to transmit at
a regular reduced time interval the second warning pulsed LED light
signal at a second wavelength. In addition, the first controller
815, generates continued second acknowledgment pulsed LED light
signal. The first controller 815, may also emit a third warning
pulsed LED light signal at a third modulated reduced duty cycle and
third wavelength, as compared to the first and second sectors 811
and wavelengths of the light support 801.
[0542] At such time as the aircraft 876 has closed to a distance
sufficient to detect the third warning pulsed LED light signal by
another set of second receivers 823, the second controller 827,
initiates the transmission of a third responsive pulsed LED light
signal at the third wavelength.
[0543] The issuance of successive warnings and responsive pulsed
LED light signals may occur until such time as a compliance signal
is generated by the second controller 827, indicating alteration of
course of the aircraft 876. The first controller 815, may
simultaneously emit three or more warning pulsed LED light signals
for detection by the aircraft 876. Further, the first controller
815, may alter the visual warning light signal as integral to the
rotating beacon 878, and/or strobe 880, for generation of a faster
and/or more versatile observable warning light signal at such time
as the controller initiates transmission of the second or third
warning pulsed LED light signals.
[0544] The controller 815, may also transmit by pulsed LED light
signal continuous information such as the coordinates identifying
the location of the obstacle 896. Further, the controller 815, may
transmit by pulsed LED light signal atmospheric information and/or
aircraft navigation guidance information which may be useful to a
pilot of an aircraft 876.
[0545] Real-time transmission of information may occur between a
second controller 827, and a first controller 815, by the exchange
of pulsed LED light signals. The interrogation pulsed LED light
signal generated by a second controller 827, of the aircraft 876
may trigger a transmission of a pulsed LED light signals from the
first controller 815, as to current air traffic proximate to a
tower 894, wind direction, wind speed, visibility, ceiling, and/or
weather conditions or other information which may be useful to a
pilot. Real-time information received from the second controller
827, may be processed for visual display on a screen integral to a
cockpit. (FIG. 84.) Alternatively, real-time information received
by the second controller 827, may be processed for generation of
voice information and instructions by transmission through a
speaker integral to a cockpit or through headphones.
[0546] An aircraft 876, obstacle 896, and/or tower 894, may include
more than one LED light support 801, for simultaneous generation of
one or more warning light signals or SIT-TEL signals. Each light
support 800 801, may be connected to an independent first
controller 815, for generation of independent pulsed LED light
signals. A pilot may select a particular wavelength of pulsed LED
light signals for receipt of a particular type of information. For
example, a first wavelength may include warning information as to
the coordinates or location of an obstacle 896. A second wavelength
may provide air traffic control information. A third wavelength may
provide information as to weather and a fourth wavelength may
provide navigation guides. A pilot may therefore receive different
types of information from more than one light source 801, and first
controller 815, as integral to a tower 894, and/or obstacle
896.
[0547] The systematic information transfer through encrypted/pulsed
light (SIT-TEL) systems may also be used to transmit approach
and/or position information to an aircraft 876. An acknowledgment
protocol as earlier described may be used between an aircraft 876
and/or tower 894 to facilitate landing. The SIT-TEL system may
communicate a visual reference descent point identifying a position
at which the aircraft 876, may or may not leave the constraints of
the published approach vector for an airport. The SIT-TEL system
may also communicate a wave-off or abort point based upon tracking
of approach vectors for aircraft 876 which are beyond acceptable
parameters. In both these situations, a SIT-TEL signal may be
instantaneously generated by a first support 801, and first LED
light sources 803, integral to a tower 894, for receipt by second
receivers 823, and second controller 827, integral to the aircraft
876. The generated SIT-TEL signal will cause the second controller
827, to issue an audible, visual, and/or oral alarm or warning to a
pilot during landing approach activities. An acknowledgment
protocol may then be transmitted by the second LED illumination
sources 829, for receipt by the first receivers 819, integral to
the tower 894. The SIT-TEL system used in association with approach
landing activities for an aircraft 876, are supplemental to the
communication systems of VHF, UHF, and TCAS proximity warning.
Real-time flight information may also be exchanged between the
aircraft 876, and the tower 894, related to the aircraft identity,
flight plan, altitude, direction, rate of descent, and wind
direction, wind speed, ceiling, instrument approaches, visibility,
traffic conditions, landing clearance, as well as other types of
aircraft landing information.
[0548] The systematic information transfer encrypted/pulsed light
signal (SIT-TEL) system may additionally be utilized in conjunction
with airport taxi lights 898, runway lights 900, runway approach
lights 902, and airport support vehicle lights 904.
[0549] A plurality of taxi lights 898, may be positioned adjacent
to an airport and runway 906. The taxi lights 898 are generally
blue in color and are normally attached to a post support.
Proximate to each taxi light 898, is located a marker 910 which
identifies the location of a particular taxi light 898 for
reference by a pilot during taxiing and/or radio communications
with a control tower 894. The taxi lights 898, as known assist in
identification of the position of an aircraft 876, on the ground
and function as a reference for aircraft 876, taxiing to a gate for
docking or from a gate in anticipation of departure and/or
takeoff.
[0550] The SIT-TEL system used in conjunction with taxi lights 898,
involves the transmission of a pulsed light signal from a beacon
878, attached to the top and/or bottom of the fuselage of an
aircraft 876. Alternatively, the wing lights 908, for an aircraft
876, may be adapted to include a support 801, having a plurality of
first LED light sources 803, for the SIT-TEL signaling system. The
wing lights 908, and/or beacon 878, continuously operate to provide
constant and/or flashing or rotational illumination relative to an
aircraft 876.
[0551] The SIT-TEL system as utilized in association with a
plurality of taxi lights 898, generally places a second LED light
support 801, having the second LED light sources 829, and second
receivers 823, integral to a marker 910, where each marker 910 is
positioned proximate to and is regularly spaced along an airport
taxi way. Each taxi light 898, may be powered by a hardwired
electrical source and/or connected to a battery which may be
rechargeable. Each taxi light 898, second illumination source 829,
and/or second receiver 823, is also electrically connected to a
second controller 827, which may be separated from the taxi lights
898, at a central location. A second converter 825, may be coupled
to the second controller 827, for conversion of electrical signals
from the second receiver 823, to digital signals, for processing
within the second controller 827. The second controller 827, is
constructed to pass information to a control center and/or control
tower 894, by optical pulsed light within the SIT-TEL system or via
wire connections. More than one controller 827, may be in
communication with a single and/or group of taxi lights 898.
[0552] The taxi lights 898, as a portion of the SIT-TEL system may
be organized into patterns and/or groups. Each collection, pattern,
and/or group of taxi lights 898, may be in electrical communication
with one or more second controllers 827. Further, a second
controller 827, may be in communication directly with a control
tower 894, or an additional main controller to facilitate transfer
of information through transmission of free space pulsed LED light
signals. The SIT-TEL signaling system utilized in association with
a plurality of taxi lights 898, is designed to facilitate the
tracking of aircraft 876, on the ground as on or adjacent to a
runway 906, and/or airport. Tracking is accomplished through the
transmission of a pulsed light signal from the beacon 878, and/or
aircraft lighting system. Alternatively, the SIT-TEL signaling
system may be transmitted through the wing lights 908, taxi or
recognition lights of the aircraft. The beacons 878, and/or wing
lights 908, continuously emit a visual signal to identify the
aircraft 876 where relative positioning of the aircraft may be
determined.
[0553] A first controller 815, may generate through SIT-TEL signals
identification information and/or call signs for an aircraft 876.
This pulsed LED light signal may be detected by a second receiver
823 integral to one or more of the taxi lights 898. Each taxi light
898 forwards the received pulsed LED light signal to a second
controller 827 for relay of information related to the existence of
an aircraft 876, and the aircraft 876 call sign or identification
to a main controller or tower 894. Each taxi light 898, also
transmits to the control tower 894, a pulsed LED light signal which
identifies, the location of the individual taxi light. The location
of the aircraft 876, relative to the taxi way may therefore be
established. Alternatively, the taxi lights 898, may be
electrically connected to a second controller 827, and the second
controller 827, may be electrically connected to the tower 894,
through the use of cable and/or wires for transmission of
information therebetween.
[0554] Traffic controllers within the control tower 894, may
therefore be provided with real-time positioning of an aircraft
876, taxiing adjacent to a runway 906, without reliance upon radio
frequency communications.
[0555] A recognition protocol may be utilized for the transmission
of encrypted pulsed LED light signal messages to insure the
security and verification as to the accuracy of communications
between an aircraft 876, and a tower 894. Further, the existence of
a recognition protocol assists to filter out background or other
light noise signals.
[0556] A tower 894, may contact a second controller 827, for
activation of a selected taxi light 898, to transfer a desired
pre-stored and/or real-time SIT-TEL pulsed light signal from second
illumination sources 829, for transmission to the first receivers
819, integral to the aircraft 876. Traffic regulation signals such
as delay gate departure, remain in a stationary position relative
to the taxi way, or proceed to the end of the runway may occur
without the need for radio frequency transmissions. The SIT-TEL
system as incorporated into taxi lights 898, and/or interfaced to
an aircraft 876, improves the safety of ground travel of aircraft
876, aircraft personnel, and travelers by identifying in real-time
the exact location of an aircraft 876, relative to a taxi way
and/or runway 906.
[0557] The taxi lights 898, may include one or a plurality of
second illumination sources 829, having different wavelengths of
emitted light. A taxi light 898, may therefore simultaneously
generate one or more of a plurality of SIT-TEL signals for receipt
by a tower 894, and/or an aircraft 876. In addition, the taxi
lights 898, may include one or a plurality of second receivers 823,
to recognize, detect, and/or receive different wavelengths of
transmitted SIT-TEL signals.
[0558] The systematic information transfer through encrypted/pulsed
light (SIT-TEL) system may also be included as an integral
component of a runway 906, lighting system. The runway lighting
system includes the same LED transmission and receptor components
as earlier described in association with the taxi lights 898,
and/or aircraft 876. The runway lights 900, and lighting system
also includes one or more second controllers 827, which are in
communication with individual runway lights 900, a tower 894,
and/or an aircraft 876.
[0559] The runway lights 900, are regularly spaced along and are
positioned adjacent to a runway 906. The runway lights 900
simultaneously provide illumination of a runway 906, and transmit
SIT-TEL signals either through free space transmissions and/or
through the use of traditional wire or cables to a control tower
894. The runway lights 900, may additionally transmit SIT-TEL
signals through free space transmissions to an aircraft 876.
[0560] The runway lights 900, through the use of SIT-TEL
transmissions indicate the presence and location of an aircraft
876, relative to a runway 906. The runway lights 900, may transmit
SIT-TEL signals to an aircraft 876, to advise of departure
clearance and/or holding status in real-time. The aircraft 876,
includes first receivers 819, and first controller 815, for receipt
of transmitted real-time SIT-TEL signals and for acknowledgment of
receipt of SIT-TEL instructions. The controller 815, is in
communication with a screen display, audio alarm, visual lights,
and/or voice generation software and equipment within a cockpit as
earlier described.
[0561] The runway lights 900, may emit a desired color or type of
light signal. For example, in an aircraft hold situation, the
second controller 827, may flash a portion of the runway lights
900, in a different color such as red to communicate that takeoff
clearance has been delayed. The runway lights 900, and particularly
the second receiver 823, and second controller 827, may receive
this instructions through the use of a SIT-TEL signal generated by
the LED illumination sources of a tower 894.
[0562] The second controller 827, coupled to the runway lights 900,
may initiate the transmission of preprogrammed SIT-TEL messages to
either the tower 894, or to a an aircraft 876, according to a
preprogrammed cycle. For example, a runway light 900, may
alternatively transmit through an SIT-TEL communication the
position of an aircraft 876, and aircraft identification, where the
next SIT-TEL signal transmitted is a repeat of the instructions
received from the tower 894, to delay departure along a runway 906.
Any number and/or combinations of real-time and/or preprogrammed
communication messages may be transferred between an aircraft 876,
runway light 900, and control tower 894. A pilot may also transmit
preprogrammed information to either the runway lights receiver,
and/or the tower 894, through the first LED illumination sources
803, and first controller 815.
[0563] The SIT-TEL communication system may be incorporated into
runway approach lights 902. Initially, the illumination sources for
the runway approach lights 902, will be required to upgrade and
replace traditional illumination elements with LED technology. The
upgraded approach lights 902, will include a light support 801,
second LED illumination sources 829, second receivers 823, and
second controller 827. The first controller 815, first LED
illumination sources 803, and first receivers 819, are integral to
an aircraft 876. The features and functions as earlier described
related to the taxi lights 898, and/or runway lights 900, are
equally applicable to the runway approach lights 902.
[0564] The runway approach lights 902, provide illumination as
visual strobe lights indicating a correct approach for a runway
906. A second controller 827, may therefore regulate a portion of
the LED light support 801, to emit a visual strobe signal while
another part of the LED support 801, may be utilized for SIT-TEL
communications with either a descending aircraft 876, and/or a
tower 894. The runway approach lights 902, may function as a
transmission source for the intermediate relay of real-time
information and/or instructions to a descending aircraft 876,
proceeding on an approach vector for landing on a runway 906.
[0565] The tower 894, may track an approach vector for an aircraft
876, through radar/VFR air traffic control systems. As a backup to
the radio frequency communications, duplicate instructions may be
transmitted by the approach lights 902, for receipt by the first
receivers 819, integral to the aircraft 876. Simultaneously, an
airplane 876, may transmit SIT-TEL pulsed signals identifying the
call sign or identification for the airplane 876, and information
related to vector, rate of descent, speed, and altitude in
real-time for transfer by the approach lights 902, to the control
tower 894. A computer/processor may receive data communicated by
the SIT-TEL LED pulsed light system for verification of acceptable
approach parameters. Analysis of the aircraft approach may result
in the transmission through radio frequency and SIT-TEL signals of
an abort approach message due to the existence of unacceptable
approach parameters. Alternatively, a tower 894, may transmit
through the approach lights 902, by issuance of radio frequency
and/or SIT-TEL communications, a warning that approach parameters
for an aircraft 876 are required to be modified for a successful
landing. The approach lights 902, may alternatively continuously
transmit through emission of SIT-TEL communications information
such as wind direction, wind velocity conditions, weather
information, runway status, ceiling information, and/or other
information as appropriate to facilitate landing of the aircraft
876. Alternatively, the approach lights 902, may transmit through
emission of SIT-TEL signals a backup transmission to an aircraft
876, advising of an emergency situation to break-off an approach
for a runway 906.
[0566] The approach lights 902 have the flexibility to transmit
SIT-TEL communication signals at different wavelengths either
individually or simultaneously in conjunction with a plurality of
visually different, distinct, or combination types of visual
warning or illumination light effects.
[0567] The approach lights 902, as regulated by the second
controller 827, may also alter a pattern of strobe or other
illumination for an approach to a runway 906. The alteration of a
pattern of illumination for the approach lights 902, and/or the
color of the transmitted light, may function as an additional
visual warning to an aircraft 876, positioned upon or approaching a
runway 906. The alteration of a standard white strobe approach
signal to a light signal of a different color or wavelength, and
the change of the stroboscopic or interval may immediately advise a
pilot of a warning prior to receipt of a radio frequency
transmission. The transfer of a distinct visual warning in
conjunction with transmission of a SIT-TEL pulsed light warning
signal may communicate warning information to a pilot at an
improved rate of communication transfer as compared to radio
frequency transmissions.
[0568] It should be noted that free space transmissions for
aircraft 876 may occur within the earth's atmosphere and may be
equally applicable for SIT-TEL communications outside the earth's
atmosphere as related to space craft communications.
[0569] The SIT-TEL communication system may be incorporated into
airport support vehicle lights 904. The traditional illumination
sources of a rotating beacon 878, are required to be replaced and
upgraded with LED technology upon a support vehicle 912. The
airport support vehicle lights 904, include a light support 801, a
plurality of second LED illumination sources 829, at least one
second receiver 823, and at least one second controller 827. The
features and functions as earlier described related to the taxi
lights 898, runway lights 900, and approach lights 902, are equally
applicable to the airport support vehicle lights 904.
[0570] The airport support vehicle lights 904, provide illumination
as a mechanically or simulated rotating beacon 878, indicating the
location of the airport support vehicle 912 relative to an aircraft
876, and gate of an airport. The second controller 827, functions
to illuminate second LED illumination sources 829, to emit a visual
light signal observable by an aircraft 876. The second controller
827, also functions to illuminate second LED illumination sources
829, to emit a SIT-TEL communication to either a first receiver
819, integral to an aircraft 876, or to a tower 894, to indicate
and track the position of the airport service vehicle 912, relative
to an aircraft 876, and airport. The airport service vehicle light
904, may function as a real-time position indicator and to
communicate through SIT-TEL signals information as to the status of
the performance of specific duties. For example, the SIT-TEL
communication system through the second LED light sources 829, as
integral to a fuel truck may advise the first receivers 819,
integral to an aircraft 876 of the location of the airport service
vehicle 912, and refueling status.
[0571] The tower 894, and/or aircraft 876, may therefore track the
position and status of activities of the airport service vehicle
912, relative to an aircraft 876. In this regard, the SIT-TEL
communication systems may function as a backup for, or as a
replacement of, radio frequency transmissions between an aircraft
876, an airport service vehicle 912, and/or a tower 894.
[0572] The SIT-TEL communications related to the airport service
vehicle light 904, may be continuously emitted or intermittently
activated. The second controller 827, includes preprogrammed
signals such as continuous vehicle identification, and various
status identifiers which may be selected or changed by an aircraft
service personnel during the performance of duties.
[0573] The SIT-TEL communications from the second LED illumination
sources 829, integral to an airport service vehicle light 904, may
transmit messages simultaneously or individually on one or more
wavelengths for detection by first receivers 819, integral to an
aircraft 876, and/or second receivers 823, integral to a tower 894.
The second LED illumination sources 829, are comprised of LED
lights of more than one wavelength which may be grouped into one or
more collections and/or sectors 811 as earlier described.
[0574] The second controller 827, may also regulate the provision
of different wavelengths of visual and/or SIT-TEL light signals
simultaneously and/or independently. For example, an airport
service vehicle light 904, may simultaneously emit a desired type
of visual signal, a first wavelength SIT-TEL signal to a first
receiver 819, integral to an aircraft 876, and a second wavelength
SIT-TEL signal to a second receiver 823, integral to a tower 894.
The second controller 827, may also regulate the generation of an
emergency visual signal and simultaneously emit an emergency
SIT-TEL warning communication to an aircraft 876, and/or tower
894.
[0575] The airport service vehicle light 904, and LED light support
801, may be attached to the top of a post. Alternatively, the
airport service vehicle light 904, may be attached at location
relative to an airport service vehicle 912. Generally, the most
common wavelengths of color for the airport service vehicle lights
904, is either amber, green, and/or red.
[0576] The second controller 827, positioned integral with an
airport service vehicle 912, may include preprogrammed locations
relative to an airport. An individual may therefore select an
appropriate location via an entry pad or keyboard to alter the
pulsed SIT-TEL signal to reflect a change in position of the
airport service vehicle 912. Alternatively, a plurality of
positional receivers may be disposed at various locations about an
airport. Each of the positional receivers may be constructed for
transmission of a preprogrammed location identification signal to a
tower 894, through SIT-TEL signals and/or connected to the tower
894, by wire or cable connections. In this embodiment, the airport
service vehicle light 904, continuously emits an identification
signal which is detected by at least one adjacent positional
receiver. Upon receipt of the SIT-TEL signal from the airport
service vehicle light 904, a pulsated light position indicator
signal is generated to either an aircraft 876, and/or tower 894, by
the positional receiver. The second LED illumination sources 829,
as coupled to the positional receivers may simultaneously
communicate a pulsed SIT-TEL signal representative of the location
of the positional receivers as well as the identification of the
type of signal received from the airport service vehicle light
904.
[0577] Each second controller 827, as integral to an airport
service vehicle light 904, may include a pre-programmed coded
pulsed signal identifying the particular type and/or function for
an airport service vehicle 912. For example, a baggage transport
may have a different pre-programmed pulse signal as compared to a
fuel truck, a food service vehicle, and/or an aircraft maintenance
vehicle. Alternatively, the type of aircraft service vehicle 912,
may be indicated through the SIT-TEL signals of different and
independent wavelengths.
[0578] The use of a SIT-TEL communication system in association
with a second controller 827, of an airport service vehicle light
904, permits communication to a first receiver 819, and first
controller 815, within a cockpit for an aircraft 876, to indicate
the real-time status of food replacement, fuel delivery, baggage
loading or unloading, and/or maintenance completion. A pilot may
therefore advise the crew and/or passengers as to the status of a
craft to assist in departure. In addition, a SIT-TEL system in
association with the first controller 815, and first LED
illumination sources 803, integral to a beacon 878, and/or wing
lights 908, may expedite communication that an aircraft 876, is
ready and available to receive food, fuel, and/or baggage loading
and unloading which in turn enables faster preparation for
continued aircraft service. The use of the SIT-TEL system with
respect to an aircraft 876, and/or airport support vehicle 912,
reduces the necessity for use of radio frequency transmissions
proximate to an airport by substitution with free space pulsed LED
transmission and detection signals.
[0579] The components, features, and applications as earlier
described related to the SIT-TEL LED pulsed light communication
system are equally applicable for use in a marine application.
[0580] In general, an LED light support 801, having first LED
illumination sources 803, will be placed at a suitable location
aboard a first vessel 916. (FIG. 73.) The LED light support 801,
may include a rotational device 805, culminator assembly 807,
stationary and/or rotatable reflectors 809, and/or sectors 811,
and/or different wavelengths of LED light sources as earlier
described. The LED light support 801, is coupled to a vessel power
supply and/or may be battery operated having rechargeable solar
cells as earlier described or wave-action generators.
[0581] A second LED light support 801, having second LED
illumination sources 829, second receiver 823, second converter
825, and second controller 827, may be integral to a marine buoy
918, lighthouse 920, and/or other vessel. The second receivers 823,
second controller 827, and/or second LED illumination sources 829,
are constructed and arranged for receipt of SIT-TEL LED pulsed
light communication signals as transmitted from the first vessel
916, for communication recognition, verification, and responsive
communication as earlier described with respect to the motor
vehicles, aircraft, taxi lights, approach lights, and/or runway
lights.
[0582] The use of the SIT-TEL system in association with a buoy
918, preferably enables enhanced visualization of the location of
the buoy 918, while simultaneously transmitting an SIT-TEL LED
pulsed light signal which may indicate pre-programmed and/or
real-time information for transmission to the vessel 916. The
second controller 827, as integral to the marine buoy 918, may
transmit pre-stored information such as the identification number
of the buoy, the fact that the buoy may be an east channel marker
and the depth of the water at the location of buoy 918. In
addition, the second receivers 823, may be disposed about the buoy
918, at various locations where an individual second receiver 823,
will only detect a transmitted SIT-TEL signal at such times as a
first vessel 916, is outside of a marked channel. In this instance
the selected second receiver 823, will generate a signal to the
second controller 827, which will in turn generate a responsive
warning signal to the first vessel 916, for receipt by the first
receivers 819, that the first vessel 916, is outside of the marked
main channel and may be on a course for running aground and/or
striking underwater obstacles.
[0583] The second receivers 823, as integral to the buoys 918, may
also be adapted to receive SIT-TEL signals transmitted from the
first vessel 916, via the first LED illumination sources 803, and
first controller 815, for communication of information such as the
registered name and port for the first vessel 916. The buoy 918,
may then forward the identity of the first vessel 916, to a second
buoy 918, and/or a harbor control center through the use of
additional SIT-TEL LED pulsed illumination signals. Any number of
buoys 918, may be utilized to sequentially transmit SIT-TEL pulsed
LED illumination signals to a harbor master related to
communications from a first vessel 916.
[0584] The first controller 815, as integral to the first vessel
916, and the second controller 827, as integral to the buoy 918,
may also include a pre-stored and/or pre-programmed recognition
protocol related to pulsed LED SIT-TEL light signals for initiation
of communication therebetween.
[0585] The second LED illumination sources 829, as integral to the
buoy 918, are constructed and arranged to provide a visual LED
signal within the red and/or green spectrums which may be used for
navigation purposes. The visual LED signals as transmitted by the
second illumination sources 829, may be flashing, pulsed,
modulated, and/or may simulate the appearance of rotation as
earlier described. Alternatively, the LED light support 801, as
integral to the buoy 918, may be physically rotated via a
rotational device 805, as earlier described.
[0586] A harbor master may utilize a series of buoys 918, to
sequentially transmit a communication to a first vessel 916, for
regulation of marine traffic through a channel by the use of
SIT-TEL communication signals. The use of SIT-TEL communication
signals may be supplemental to the transmission of radio frequency
transmissions. Alternatively, the buoy 918, is not required to be
utilized exclusively within a channel or harbor application. The
buoy 918, may be a position identification source and/or obstacle
marker.
[0587] The buoy 918, may be positioned at any location within a
body of water to continuously transmit a pulsed LED SIT-TEL signal
for communication of information such as longitude and latitude
coordinates. Alternatively, the buoy 918, may become activated and
transmit SIT-TEL signals at such time as the second receiver 823,
receives a triggering signal from a first set of LED illumination
sources 803, integral to a first vessel 916. Each buoy 918, may
also transmit real-time information such as water temperature,
barometric pressure, changes in barometric pressure, temperature,
and/or wind speed and direction. The buoy 918, may include a long
life lithium battery and/or a backup rechargeable solar cell as
earlier described.
[0588] Buoy's 918, may also be utilized to record marine traffic
for tracking purposes. For example, a first vessel 916, may
transmit the vessel identity to a buoy 918, through the use of
SIT-TEL communication signals. The buoy 918 may then record the
date, time of transmission, and/or destination information related
to the vessel 916. The SIT-TEL signal as received by the second
receiver 823, is preferably recorded on the second controller 827.
In the event that a first vessel 916, becomes overdue then a
retrieval craft such as an airplane or helicopter may be dispatched
by a Coast Guard unit having interrogation SIT-TEL capabilities. A
Coast Guard vessel or aircraft may then fly within range of a buoy
918, and transmit an SIT-TEL interrogation signal which will
trigger the second controller 827, to dump all pre-stored marine
traffic data for transmission to the Coast Guard aircraft or vessel
via a responsive SIT-TEL signal. A Coast Guard and/or searching
vessel may thereby identify time and direction of travel for a lost
vessel to narrow a search area thereby improving the probability of
survivor retrieval. In addition, a vehicle such as an aircraft 876,
may fly within the proximity of a buoy 918, for transmission of a
first SIT-TEL signal to be received by the second receiver 823,
and/or second controller 827, to modify future SIT-TEL
communications to be generated by the second LED illumination
sources 829. In this regard, warning signals may be activated
and/or altered on the marine buoy 918. A marine vessel 916 which
has previously been outside of radio frequency transmission range
may therefore receive updated SIT-TEL communication signals from a
buoy 918, related to warnings such as adverse weather and/or wave
conditions.
[0589] SIT-TEL communication signals as transmitted between a first
vessel 916, and a second vessel 922, may be provided in the manner
as indicated as related to SIT-TEL transmissions between aircraft
and/or a control tower 894, as earlier described.
[0590] SIT-TEL communication signals may also be transmitted
between a first vessel 916, and a lighthouse 920, in a manner
similar to the SIT-TEL communications identified between an
aircraft 876, and tower 894, as earlier described. SIT-TEL
communications being generated by a lighthouse 920, are anticipated
to be prominently pre-recorded and/or pre-stored communication
signals as integral to the second controller 827. It is anticipated
that the SIT-TEL communication signals as generated by a lighthouse
920, will transmit information such as longitude and/or latitude or
other coordinates, and navigation information which will assist a
first vessel 916, from approaching a marine hazard.
[0591] The components, features, and applications as earlier
described related to the SIT-TEL LED pulsed light communication
system are equally applicable for use in a subway, bus, and/or mass
transit application. (FIGS. 74 and 77.) For convenience, the
subway, bus, and/or mass transit vehicle will be identified by the
numeral 924. The subway/bus 924, preferably includes the elements
as earlier identified and described related to the LED light
support 801, first LED illumination sources 803, culminator
assembly 807, sectors 811, power source 813, first controller 815,
first receiver 819, and converter 821.
[0592] A second receiver 823, second converter 825, second
controller 827, and second LED illumination sources 829, are
preferably constructed and arranged for attachment to a street sign
and/or traffic light 926.
[0593] In the mass transit application, the first controller 815,
as integral to the bus and/or subway 924, includes pre-stored
information as to the vehicle identification number, schedule, and
vehicle route. The second controller 827, as integral to the street
sign and/or traffic light 926, includes pre-stored identification
information such as a position location relative to a map. Within
the subway mass transit application position identifiers 928, may
be regularly spaced along a route in substitution for the street
sign/traffic lights 926.
[0594] Initially, the first controller 815, will signal initiation
of a first SIT-TEL pulsed light communication signal to be
transmitted for detection by the second receivers 823, as integral
to a street sign 926, and/or position identifier 928. The second
controller 827, as coupled to the street sign 926, or position
identifier 928, will process the received signal for generation of
a second SIT-TEL LED pulsed light signal for transfer to a
centrally located third receiver 930, as connected to a third
converter 932, third controller 934, and third LED illumination
device 936. The third receiver 930, third controller 934, and/or
third LED illumination device 936, are preferably elevated with
respect to the street signs 926, and/or position identifiers 928,
in order to receive pulsed LED SIT-TEL light signals from a
plurality of street signs 926, and/or position identifiers 928. The
third controller 934, may be electrically coupled to a traffic
processor 938, which functions as a central processing and tracking
location related to SIT-TEL signals received from the third
controller 934. The second controller 827, as integral to the
street sign 926, and/or position identifier 928, may record the
first SIT-TEL signal received from the first controller 815. The
second controller 827, may then relay the first SIT-TEL signal
including vehicle identification along with additional information
such as an identification signal corresponding to a street sign
926, and/or position identifier 928, address and a signal
corresponding to the time of transmission of the SIT-TEL signal.
The third controller 934, as receiving the first and second SIT-TEL
signals may transfer information to the traffic processor 938,
which may compare the information to a preset map and/or schedule
for transmission of SIT-TEL signals back to the street signs 926,
and/or position identifiers 928. The street signs 926, and position
identifiers 928, as receiving a SIT-TEL signal from the traffic
processor 938, may initiate the transmission of an additional
SIT-TEL signal for receipt by a plurality of displays 940, as
representative of the tracking and/or location of a bus/subway 924
proceeding along a preselected route. Potential passengers waiting
for a bus/subway 924, may therefore track in real-time the location
of the bus/subway 924. The tracking of a subway/bus 924, is thereby
facilitated. Additionally, bus stop and/or subway connection
information may also be transmitted by SIT-TEL pulsed LED light
signals for receipt upon the displays 940, to assist passengers
during travel activities.
[0595] Each subway/bus 924, may also include a display 940, which
is adapted to receive a second SIT-TEL pulsed light signal as
generated by a street sign 926, and/or position identifier 928, for
processing by a first controller 815. The position location
identifiers from the street signs/traffic light 926, and/or
position identifier 928, may assist passengers to identify the
real-time location of the vehicle with respect to a pre-selected
route to facilitate departure locations.
[0596] The wavelengths selected for the first LED illumination
sources 803, second LED illumination sources 829, and/or third LED
illumination devices 936, may be identical and/or different to
facilitate communication of SIT-TEL systems. The first receiver
819, second receiver 823, and/or third receivers 930, may be
adapted to receive a particular wavelength of generated LED pulsed
light signal. Alternatively, each of the first controllers 815,
second controllers 827, and/or third controllers 934, may be
coupled to a scanner 831, which searches to identify transmitted
SIT-TEL signals used to communicate tracking and/or other
information within a mass transit application. The use of SIT-TEL
communication signals in association with mass transit tracking
applications avoids the necessity for utilization of radio
frequency transmissions which may frequently encounter interference
from buildings or other sources within an urban environment and
facilitates real-time planning for the customers, generating
confidence in the system.
[0597] A plurality of third controllers 934, may be disposed in any
desired pattern as elevated with respect to an urban environment
for communication relay to assist in the tracking, regulation, and
control of a mass transit SIT-TEL application. The third receivers
930, third converters 932, third controllers 934, and third LED
illumination devices 936, are coupled to a power source which may
be a battery integral to the street sign/traffic light 926, and/or
position identifiers 928. The power source may be hardwired into a
power source for a city. The first LED support 801, as integral to
the bus/subway 924, may be positioned at any location including but
not necessarily limited to the front dashboard proximate to a
window, to the exterior proximate to the top of the vehicle, and/or
front of the bus/subway. In addition, the second receiver 823, may
be positioned at any location relative to a street sign/traffic
light 926, and may be located toward the top with respect
thereto.
[0598] The components, features, and applications as earlier
described related to the SIT-TEL LED pulsed light communication
system are equally applicable for use in an OPTICOM intersection
clearing application.
[0599] The OPTICOM intersection clearing device is generally
referred herein as the OPTICOM device identified by the numeral
942. (FIG. 67.) The OPTICOM device 942, includes a second receiver
823, second converter 825, second controller 827, and second LED
illumination sources 829. In addition, the OPTICOM device 942,
includes an LED support 801, having sectors 811. The OPTICOM device
942, is electrically coupled to a main power supply for a traffic
signal 926, and may be constructed to have a backup power supply
such as a battery which may be rechargeable through the use of a
solar cell.
[0600] In general, the OPTICOM device 942, and second controller
827, is connected to an override switch which is integral to the
traffic light 926. A police, ambulance, fire, or other emergency
vehicle during an emergency situation frequently requires the
immediate transposition of a semaphore to a green traffic condition
signal, to facilitate speed of arrival at an emergency situation.
In addition, the first SIT-TEL system as integral to an emergency
vehicle may also include a first receiver 819. During use of the
OPTICOM device 942, an officer or emergency personnel will activate
a switch to initiate the first controller 815, to generate a first
SIT-TEL communication signal for transmission from the first LED
illumination sources 803. The first SIT-TEL pulsed light signal
will be received by the second receiver 823, integral to the
OPTICOM device 942. The second controller 827, of the OPTICOM
device 942, will then trigger the override switch to
instantaneously transition the semaphore from either a red or amber
signal to a green light signal to permit passage of an emergency
vehicle through an intersection.
[0601] The first LED illumination sources 803, as integral to the
emergency vehicle are pointed upwardly towards the top of the
traffic light and/or semaphore 926. The second receiver 823, is
proximate to the top of the traffic light 926/semaphore. The second
receiver 823, second converter 825, second controller 827, and
second LED illumination sources 829, may be hardwired to an
electrical power source and/or powered through a battery as earlier
described.
[0602] The second receiver 823, as integral to the OPTICOM device
942, continuously receives the first SIT-TEL signal as generated
from the first LED illumination sources 803. At such time as the
second receiver 823, terminates detection of the SIT-TEL signal as
generated by the first LED illumination sources 803, a
pre-programmed timing delay may be initiated for deactivation of
the override switch to return the traffic light 926, and/or
semaphore to a normal operational condition. Alternatively, the
emergency vehicle may include an additional LED support 801, of
first LED illumination sources 803, to transmit from the back of a
vehicle once passage through an intersection has been completed. A
second SIT-TEL pulsed LED light signal may thereby be generated by
the first controller 815, for detection by the second receiver 823,
as integral to the OPTICOM device 942, for deactivation of the
override switch to return the semaphore/traffic light 926, to a
standard operational condition. Alternatively, the second
controller 827, as integral to the OPTICOM device 942, may include
internal pre-programmed software which continues to activate the
override switch, for a pre-set period of time. In addition, the
first controller 815, and second controller 827 as integral to the
OPTICOM device 942, may be programmed to proceed with a recognition
protocol as earlier described. The use of the SIT-TEL communication
signaling system may be utilized as a backup or supplemental
communication device to radar transmitters, transponders, and/or
radio frequency equipment. The OPTICOM device 942, provides a
visual activation light signal as well as a responsive SIT-TEL
communication signal for receipt by the second receivers 823,
and/or observation by an emergency personnel or policeman to
indicate that, in fact, the override switch has been activated to
change the semaphore/traffic light 926, to a green configuration to
permit unobstructed passage of the emergency vehicle through an
intersection.
[0603] The components, features, and applications as earlier
described related to the SIT-TEL LED pulsed light communication
system are equally applicable for use within a railroad crossing
application. (FIGS. 75 and 76.) Generally, black and white railroad
crossing signs having no alarm and/or gate are utilized in most all
rural environments due to the reduced level of traffic and
prohibitive cost for inclusion of more safety conscious railroad
warning indicators. The absence of alarms and gates at rural
railroad crossings increases the likelihood of motor vehicle
accidents and fatalities. Counties generally desire to have safer
railroad crossings and railroads also desire safer railroad
crossings to reduce risk of motor vehicle accidents. A need
therefore exists for an inexpensive, long life and dependable
visual and audio signal at rural railroad crossings which is easily
adaptable for inclusion within existing railroad crossing
signs.
[0604] A railroad crossing warning signal 946, is generally formed
of an LED support 801, having first LED illumination sources 803,
formed into sectors 811. In addition, the railroad crossing warning
signal 946, includes a culminator assembly 807, a power source 813,
a first controller 815, a solar energy cell 817, a first receiver
819, and a converter 821. The elements of the railroad crossing
signal are directly attached to a railroad crossing sign pole as
placed adjacent to rural railroad crossings.
[0605] The LED light support 801, having the first LED illumination
sources 803, is adapted for receipt of power from the first
controller 815, to simulate the existence of a revolving light. The
power as regulated by the first controller 815, may permit the
illumination of individual and/or groups of LED'S. The railroad
crossing warning signal may also include an audible alarm 948,
which may be used to generate a buzzing, bell, and/or siren warning
signal for detection by motor vehicles.
[0606] A train 950, preferably includes a front 952, and a back
954. A second LED light support 801, having second LED illumination
devices 829, is positioned proximate to the front 952 of the train
950. In addition, a third LED light support 800 801, including a
third receiver, third converter, third controller, and third LED
illumination sources, may be positioned proximate to the back 954
of the train 950. The second controller 827, and second LED
illumination sources 829, are constructed to continuously flash a
visible warning light signal which may include a modulated duty
cycle as earlier described. The second controller 827, and second
LED illumination sources 829, are also constructed and arranged to
continuously emit SIT-TEL communication signals as earlier
described. The SIT-TEL communication signals as generated by the
second controller 827 transmit a recognition protocol as earlier
described and are adapted for detection by the first receivers 819,
as integral to the railroad crossing sign 956. The first receiver
819, is constructed to receive the first SIT-TEL signal as
generated by the second controller 827 integral to the front 952,
of the train 950. The first controller 815, interprets the first
SIT-TEL communication signal for activation of the first LED
illumination sources 803, for the provision of a warning light
signal and simultaneously the activation of the audible alarm 948.
Power is applied to the audible alarm 948, railroad crossing
warning signal 946, first controller 815, first receivers 819, and
first LED illumination sources 803, through the use of a long life
lithium battery and/or a rechargeable battery which may receive
power from a solar power cell.
[0607] The first controller 815, upon receipt of the initial
SIT-TEL communication signal from the train 950, may initiate the
transmission of a responsive SIT-TEL signal from the first LED
illumination sources 803, for completion of the recognition
protocol. The railroad crossing warning signal 946, includes first
receivers 819, positioned on opposite sides of the railroad
crossing sign 956, along an axis parallel to the direction of the
train 950. The first receivers 819, are thereby constructed to
receive SIT-TEL communication signals from only one direction which
are on opposite sides of the railroad crossing sign 956.
[0608] The rear, back, and/or caboose, of the train 950, includes a
the third set of LED illumination devices for generation of a
second SIT-TEL communication signal. Once a train 950, has passed a
railroad crossing, the transmission of the second SIT-TEL
communication signal may be detected by the opposite first receiver
819, which deactivates the audible alarm 948, and/or the warning
signal light as generated by the first controller 815.
Alternatively, the first controller 815 may include a timer for
deactivation of the visible warning light signal and audible alarm
948 following passage of a preselected period of time. The first
SIT-TEL light signal and the second SIT-TEL light signal are formed
of different patterns of pulsated light signals as generated by the
second controller 827, and/or third controller. Any wavelength of
SIT-TEL signal may be selected for transmission from the first LED
illumination sources 803, second LED illumination sources 829, and
third LED illumination sources.
[0609] A motor vehicle may include a fourth receiver, fourth
converter, a fourth controller, a fourth LED illumination device,
and an override switch. The fourth receiver is adapted to
additionally receive the first SIT-TEL train warning signal in a
manner similar to the railroad crossing warning signal. The receipt
of the initial SIT-TEL warning signal from the train 950, may be
processed by the fourth controller for activation of an override
switch, which may be electrically coupled to the radio of the motor
vehicle. In addition, the fourth controller may be coupled to the
fourth LED illumination device, positioned to the interior
proximate to the dashboard of the motor vehicle. The receipt by the
fourth receiver, of the first SIT-TEL warning signal as generated
by the train 950, causes the controller, to initiate a warning
illumination from the fourth LED illumination sources, for
observation by an individual as a visual warning signal as to the
existence and proximity of a train. An individual may therefore
receive a warning indication from a railroad crossing warning
signal 946, as well as from the interior of an automobile pursuant
to the illumination of the fourth LED illumination device, to
heighten awareness as to the existence of a train 950. The fourth
controller, following the receipt of the first SIT-TEL warning
signal from the train 950, may, via the override switch, terminate
power to a motor vehicle radio and/or generate a voice message
through a speaker as earlier described.
[0610] The components, features, and applications as earlier
described related to the SIT-TEL LED pulsed light communication
system are equally applicable for use in an urban suburban
communication system 966. (FIGS. 74 and 77.)
[0611] The urban suburban communication system 966, is generally
formed of an LED light support 801, having first LED illumination
sources 803, formed into sectors 811. The urban suburban
communication system 966, also includes a main power source 813, as
earlier described along with a battery backup power source which
may be formed of a rechargeable solar cell 817. The urban suburban
communication system 966, further includes at least one first
controller 815, at least one first receiver 819, and at least one
first converter 821. The urban suburban communication system 966,
is positioned to the top of a central building 968, or tower 970,
as related to a geographic area.
[0612] The urban suburban communication system 966, is adapted to
generate SIT-TEL pulsed LED light signals in a horizontal and
downwardly direction related to the location of the building 968,
and/or tower 970. The urban suburban communication system 966, may
be formed of a circular, oval, octagonal, hexagonal, square, and/or
rectangular shaped LED light support 801. Sectors 811 of
culminators 807, and/or first LED illumination sources 801, may be
angularly offset for the emission of light at any desired angle of
illumination. The first controller 815, controls the emission of
SIT-TEL communication signals from the first LED illumination
sources 803, in one or more desired directions sequentially,
individually, and/or simultaneously. The first LED illumination
sources 803, are constructed and arranged to additionally provide a
warning light signal such as a beacon for visual recognition by an
aircraft 876.
[0613] The urban suburban communication system 966, may also formed
of a plurality of relay sites 972, which include at least one
second receiver 823, at least one second converter 825, at least
one second controller 827, and at least one set of second LED
illumination sources 829. The relay sites 972, may be secured to
street and/or traffic signals 926, and/or street lamps.
Alternatively, the relay sites 972, may be placed at any desired
location within an urban/suburban environment. Any number of relay
sites 972, may be used for detection of initial SIT-TEL
communication signals as emitted from the urban suburban
communication system 966.
[0614] The relay sites 972, transmit and/or receive SIT-TEL
communication signals to or from a user site which may be placed
upon a dwelling, building, and/or other structure 976. The user
sites include at least one third receiver 930, at least one third
converter 932, at least one third controller 934, and at least one
set of third LED illumination sources 936. The user site is
electrically coupled to a visual display 940, audible alarm, and/or
LED light support 801, having LED illumination sources. Any number
of relay sites 972, may be sequentially positioned between the
urban suburban communication system 966, and the user site. Each
SIT-TEL communication signal may therefore be passed from the first
LED light sources 803, to a second receiver 823, integral to an
initial relay site 972, for successive transmission to additional
second receivers 823, of relay sites 972, for final SIT-TEL
transmission to a third receptor 930, integral to a user site. The
third controller 934, may then process the final SIT-TEL signal at
the dwelling, building, and/or structure 976, for issuance of a
signal on the display 940, activation of an LED light on a light
support 801, and/or activation of an audible alarm. SIT-TEL
communication signals may therefore be processed sequentially from
the urban suburban communication system 966, through successive
relay sites 972, to a user site. Types of SIT-TEL signals may
include but are not necessarily limited to mail messages, pictures,
photographs, advertisements, communications, news, real-time
entertainment, pre-programmed entertainment, civil defense
warnings, and/or any other type or form of communication which may
be reduce to pulsed and/or encrypted LED light signals. It is
anticipated that SIT-TEL communication signals may be used as a
supplement or replacement of modes of communication such as mail,
e-mail, advertising, billboards, cell phones, telephones, radio,
and/or television.
[0615] Additionally, the user site includes the third controller
934, and the third LED illumination sources 936, which are
constructed and arranged to emit responsive SIT-TEL communications
signals upstream through the second receivers 823, of the relay
sites 972, for further communication to the first receivers 819, of
the urban suburban communication system 966, for processing within
the first controller 815. The first controller 815, may identify a
designated recipient of the communication for generation of a
responsive SIT-TEL signal downstream, back through a series of
second receivers 823, for ultimate transition to a particular third
receiver 930, at the previously identified and designated user
site.
[0616] In this regard, each intermediate relay site 972, and user
site, is required to have a stored identification combination of
pulsed LED light signals to identify an address. The addresses for
each and every site 972, and/or user site, are stored within each
respective second controller 827, and third controller 934,
respectively. The first controller 815, second controller 827, and
third controller 934, are computers having microprocessors and
stored translation software to recognize and interpret received
SIT-TEL communication signals for communication to individuals
through the display 940, and/or audible alarms.
[0617] The urban suburban communication system 966, relay sites
972, and/or user sites, may each include more than one LED light
support 801, and one or a plurality of first receivers 819, second
receivers 823, and/or third receivers 930, respectively. The urban
suburban communication system 966, relay sites 972, and/or user
sites, may each include one or more first controllers 815, second
controllers 827, and/or third controllers 934. Each of the first
controllers 815, second controllers 827, and/or third controllers
934, may be constructed to process a selected type of SIT-TEL
communication signal. For example, one set of first controllers
815, second controllers 827, and third controllers 934, may
exclusively communicate SIT-TEL signals related to mail and/or
e-mail. Another set of first controllers 815, second controllers
827, and/or third controllers 934, may exclusively communicate
SIT-TEL signals related to cellular and/or telephone signals. Any
number of sets of controllers may be utilized as a portion of the
urban suburban communication system 966 to communicate a specific
desired type of information.
[0618] A specific type of communication signal may be assigned
exclusively to a particular wavelength of SIT-TEL pulsed LED light
communication signals. For example, cellular telephones and/or
telephone communications may be assigned to a specific wavelength
associated with an amber color. Radio communications may be
assigned to a wavelength associated with a blue color. Any desired
type of communication may be assigned a specific common wavelength
for transmission and receipt of SIT-TEL communication signals. The
SIT-TEL communication signals are not required to be exclusively in
the visible spectrum but may also be generated in the non-visible
spectrum.
[0619] Recognition protocols as earlier described are equally
applicable as related to the SIT-TEL communications between the
urban suburban communication system 966, relay sites 972, and/or
user sites.
[0620] A hardwired connection may be provided between the third
receiver 930, or the user sites, and an internally located display
940, audible alarm, and/or LED light signal. The third controller
934, may permit a user to select a type of display 940, for
communication of received SIT-TEL pulsed light signals. For
example, an individual may manipulate the third controller 934, for
generation of a processed and interpreted SIT-TEL communication
signal for display upon a screen, television, stereo, speaker,
alarm, and/or flashing or other warning light. Additionally, the
SIT-TEL communications as processed by the third controller 934,
may not be accessible to a end user without entry of security
measures to facilitate retrieval such as the use of passwords
and/or other encryption means.
[0621] The urban suburban communication system 966, relay sites
972, and/or user sites 974, may each additionally include scanners
831 and/or dials as earlier described for detection of transmitted
SIT-TEL communication signals.
[0622] The third controller 934, is constructed and arranged to
interpret digital pulses for translation into visual images for
showing on the display 940. Additionally, the third controller 934,
is constructed to issue an audible alarm, and/or a flashing LED
light signal as a portion of a civil defense warning to advise
occupants of the existence of severe weather conditions.
[0623] The third controller 934, and third LED illumination sources
936, as integral to a user site, may also be utilized to transmit
encrypted SIT-TEL light signals and/or messages on an emergency
basis as coupled to third receivers 930, integral to a police or
fire station. An individual user within a building, dwelling, or
structure 976, may therefore activate a switch causing the
initiation of a LED pulsed SIT-TEL emergency signal for
transmission to a police or fire station without the necessity of
use of a telephone.
[0624] A significant advantage of utilizing SIT-TEL communication
signals in association with an urban suburban communication system
966, is the flexibility for the provision of alternate
communication mechanisms within free space which minimize the
necessity for large expenditures for construction of an
infrastructure for a community.
[0625] The components, features, and applications as earlier
described related to the SIT-TEL LED pulsed light communication
system are equally applicable for use in a vehicle to vehicle
application.
[0626] A vehicle to vehicle SIT-TEL communication application is
similar to the earlier described applications related to motor
vehicle license plates and aircraft/aviation SIT-TEL
communications. In addition, to the SIT-TEL communications as
previously identified, an emergency vehicle 978, may include an LED
light support 801, having first LED illumination sources 803,
formed into sectors 811, as earlier described. In addition, the
emergency vehicle 978, may include at least one first controller
815, at least one first receiver 819, and at least one converter
821, as coupled to the emergency vehicle electrical system and
backup power source such as a battery. Emergency vehicle personnel
such a police officer may manipulate the first controller 815, to
either select a pre-programmed SIT-TEL signal or may generate a
SIT-TEL signal for transmission from the first LED illumination
sources 803. At least one second receiver 823, at least one second
controller 827, and at least one set of second LED illumination
sources 829, may be included within a street and/or a roadway sign.
The transmitted SIT-TEL signal as received by the second receivers
823, integral to the road sign, is preferably processed by the
second controller 827, for issuance of a message such as
"congestion", "accident", "reduced speed", and/or any other message
as appropriate for communication of traffic conditions. SIT-TEL
communications may therefore be passed through free-space from an
emergency vehicle 978, to alter roadway signs, without use of radio
frequency transmissions.
[0627] The first controllers 815, of the emergency vehicle 978, and
the second controller 827, of the roadway signs, may perform
recognition protocols to verify authenticity of transmitted
instructions and/or messages. In addition, each of the first
controllers 815, of the emergency vehicle 978, and the second
controllers 827, of the roadway signs, include identification and
recording software to assist in recording of transmitted SIT-TEL
instructions.
[0628] An emergency vehicle 978, may also transmit a SIT-TEL
communication signal to a street sign/lamp 926, a building,
structure, and/or dwelling 976, a user site, or to a relay site
972, of a urban suburban communication system 966, to track the
location of the emergency vehicle 978, and/or to communicate
messages and instructions through the use of SIT-TEL pulsed LED
communication signals. An emergency vehicle 978, may emit
pre-stored and/or real-time free-space communication signals to
another motor vehicle, aircraft 876, road sign, OPTICOM 942, urban
suburban communication system 966, railroad crossing warning sign
946, and/or any other application as identified herein. Real-time
communications may be issued through a keyboard, key pad, and/or
voice recognition software integral to the emergency vehicle
978.
[0629] The SIT-TEL communication system may additionally be
incorporated into other types of vehicles including, but not
necessarily limited to, snowplows, roadway construction vehicles,
ambulances, and/or fire trucks which utilize visual warning lights.
(FIG. 72.) In these vehicles a visual warning signal light may be
generated simultaneously with the emission of a SIT-TEL pulsed LED
light signal.
[0630] SIT-TEL communications may be accomplished between a
standard motor vehicle and an emergency vehicle 978, through the
emission of a pulsed LED SIT-TEL signal from an emergency vehicle
978, light bar as earlier described. An audible alarm, may be
generated requiring an acknowledgment signal by a driver or
passenger for actively manipulating a switch to terminate the
emission of the audible alarm thereby acknowledging receipt of the
SIT-TEL signal from an emergency vehicle. In addition, the
manipulation of a switch to terminate the audible alarm, may
simultaneously instruct the controller to illuminate LED light
sources for transmission of a confirmation SIT-TEL signal to the
originating emergency vehicle 978.
[0631] The SIT-TEL pulsed LED communication system may also be
incorporated into a flare 1000 which may include all of the
features as previously identified related to motor vehicles,
license plates, aircraft, airport facilities and vehicles, urban
communication systems, marine vessels and buoys, OPTICOM traffic
signal devices, railroads, and/or subways.
[0632] Referring to FIGS. 78 through 80, the SIT-TEL pulsed LED
light communication system and flare 1000 are described herein. The
flare 1000 includes a casing 1002 and a main body 1004. The casing
1002 includes a chamber 1006. Positioned within the chamber 1006 is
the SIT-TEL pulsed LED light control system including a first
controller 815 and a parachute 1008. Within the chamber 1006 is
located an affixation bracket 1010. The affixation bracket 1010 is
constructed and arranged for attachment to the support cords 1012
of the parachute 1008.
[0633] The main body 1004 has a cavity 1014. The cavity 1014 holds
solid fuel propellant and/or other fuel 1016 which is used to power
the assent of the flare 1000 through engine 1018. The exterior of
the main body 1004 may include one or more stabilizers 1020 to
assist in the assent of the flare 1000 following discharge from an
expulsion device which may be a mortar 1022. Within the chamber
1006 is located the first controller 815 and battery. A first
receiver 819 which may include photo diodes traverses the casing
1002 proximate to the first controller 815 and LED illumination
sources 829. The LED illumination sources 803 are positioned to the
exterior and top of the casing 1002 and are in electrical
communication with the controller 815 through wire or other
connectors 1024. The functions of the first controller 815,
battery, first receiver/photo diodes 819 and LED illumination
sources 829 are identical to the functions as earlier
described.
[0634] During launch, the flare 1000 ascends upwardly where the LED
illumination sources 803 are identified as being positioned in a
location proximate to the nose of the flare 1000.
[0635] The exhaustion of the solid fuel propellant 1016 by the
engine 1018 represents the apex of the trajectory of the flare
1000. At this point, the casing 1002 separates from the main body
1004 to open the casing 1002 for deployment of the parachute 1008.
The parachute 1008 exits the open end of the casing 1002 to deploy
the light emitting diode light sources 803 in a downwardly
direction. Following separation of the casing 1002 from the main
body 1004 an internal switch may be activated and/or a timer may
initiate the transmission of pulsed LED SIT-TEL light signals which
are used to communicate information to one or more second receivers
823.
[0636] The first receiver 819 is adapted to receive, detect,
decode, and process potentially encrypted information as
communicated by pulsed LED light signals from a third controller
1026 for programming and/or storage of messages upon the first
controller 815.
[0637] Separation between the casing 1002 and main body 1004 for
deployment of the parachute 1008 may be assisted by a controlled
explosion proximate to the affixation bracket 1010. The affixation
bracket 1010 may be a separation plate which is sealed with respect
to the interior walls of the casing 1002 to protect the first
controller 815 from adverse environmental elements. A second
separation plate 1028 may be fixed and/or integral to the interior
walls of the main body 1004 to enclose the solid fuel propellant
1016 preventing damage to the parachute 1008. The secondary
explosion to separate the casing 1002 from the main body 1004
exposes an opening in the end of the casing 1002 to open the
chamber 1006 holding the parachute 1008 for deployment of the
parachute 1008 for a prolonged descent of the flare 1000.
[0638] The flare 1000 may be ejected and/or launched from a mortar
1022. The mortar 1022 may be transportable for positioning at any
desired location within an operational theater. Alternatively, the
flare 1000 may be dropped form an aircraft and/or launched as a
missile.
[0639] A third controller 1026 may be proximate to the mortar 1022
and flare 1000. The third controller 1026 is used to program the
first controller 815 to define the pulsed SIT-TEL LED light
messages to be transmitted to troops within an operational
theater.
[0640] The third controller 1026 may be connected to a third
transmitter 1030 which is used to transmit SIT-TEL pulsed light
signals to the first receiver 819 for storage upon the first
controller 815. The third controller 1026 may further include a
third receiver which is used to receive SIT-TEL pulsed LED light
signals from an external controller or signal processor, for
further transmission to and storage upon the first controller 815
of the flare 1000.
[0641] SIT-TEL pulsed light communication signals are generated by
the LED illumination sources 803 of the flare 1000 to be received
by fourth receivers 1032 as integral to a fourth controller 1033
which is proximate to troops within an operational theater.
[0642] The fourth controller 1033 and fourth receiver 1032 may be
incorporated into a hand held transportable unit which may be
carried in the pocket of an individual and/or hidden from
observation during periods of non-use.
[0643] The fourth controller 1033 preferably includes a display
1034 which may be similar to the earlier embodiments as
described.
[0644] A fourth transmitter 1036 as electrically coupled to fourth
controller 1033 may be used to communicate pulsed LED light signals
from the ground to the first receiver 819 of the flare 1000.
[0645] The flare 1000 including the SIT-TEL communication system
may be used as a back-up to radio transmissions within an
operational theater. In addition, the flare 1000 including the
SIT-TEL pulsed LED light communication system may be utilized when
radio transmissions are not available in order to maintain secrecy
of the location of troops.
[0646] The flare 1000 including the SIT-TEL communication system in
conjunction with the fourth controller 1033 and fourth receivers
1032 enables troops to receive communications through the use of
pulsed LED light signals. The LED illumination sources 803 as
coupled to the first controller 815 are sturdy and sufficiently
strong to withstand shock exposed to the flare 1000 following
discharge of the solid fuel propellant 1016 from the engine
1018.
[0647] Alternatively, prior to deployment, the flare 1000 may be
coupled to the third controller 1026 which may be a central
processing unit via a cable 1038. Information including encryption
and/or encoding information may be passed from the central
processing unit of third controller 1026 to first controller 815
for future transmission from LED light sources 803 during use of
flare 1000. The coupling of the third controller 1026 to the flare
1000 may occur proximate to the location of the first receiver
819.
[0648] In addition to being directed to the embodiments described
above and claimed below, the present invention is further directed
to embodiments having different combinations of the features
described above and claimed below. As such, the invention is also
directed to other embodiments having any other possible combination
of the dependent features claimed below.
[0649] The present invention may be embodied in other specific
forms without departing from the spirit or essential attributes
thereof, and it is, therefore, desired that the present embodiment
be considered in all respects as illustrative and not restrictive,
reference being made to the appended claims rather than to the
foregoing description to indicate the scope of the invention.
