60/544,687 entitled "Helmet Power System" filed Feb. 17, 2004, all
of which are herein incorporated by reference for all purposes.
FIELD OF THE INVENTION
[0002] The present invention relates generally to safety equipment.
Specifically, an electrical power system for crash helmets is
described.
BACKGROUND OF THE INVENTION
[0003] Crash helmets ("helmets") are used for a variety of
purposes, providing cranial and neck safety protection for users in
industries such as sports and leisure, equipment and vehicle
operation, construction, military, law enforcement, and others.
Helmets offer basic protection of head and neck areas, providing
hard surfaces to deflect impacts from physical force or traumas
that could cause temporary or permanent physical injury. Helmets
can also provide other features beyond basic protection.
[0004] Conventional helmets may offer features such as heads-up
displays, optical or aural protection, lighting, and communication
systems. However, conventional helmet systems often require power
sources or supplies that may be heavy or externally coupled to a
helmet. Conventional helmets also require significant user
interaction in order to activate or deactivate a feature. Equipment
such as batteries, power cells, processors, communication
transceivers, night/low vision goggle or visor systems can be
implemented but require external electrical power supplies and
electrical connections to a power supply. The external connections
and power supplies are often bulky, difficult to use, and
vulnerable to damage. Additionally, external components may require
significant user interaction in order to attach and use the
feature, creating a potential safety risk. For example, a
motorcycle police officer attempting to activate and hold an
external flash light while handling a notepad or other equipment
exposes the officer to potential harm while preoccupied with
activating his light. Military personnel using a heads-up display
or night/low-vision system with their helmet while maneuvering
through difficult terrain may risk damage or vulnerability due to
external wires and power supplies inhibiting movement.
[0005] Thus, what is needed is a solution for electrical power for
crash helmets and related systems without the limitations of
conventional techniques.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] Implementation of described techniques may occur in numerous
ways, including as a system, device, apparatus, process, a computer
readable medium such as a computer readable storage medium, or a
computer network wherein program instructions are sent over optical
or electronic communication links.
[0028] A detailed description of one or more embodiments is
provided below along with accompanying figures that illustrate the
principles of the embodiments. The scope of the embodiments is
limited only by the claims and encompasses numerous alternatives,
modifications and equivalents. Numerous specific details are set
forth in the following description. These details are provided
solely for the purposes of example and the embodiments may be
practiced according to the claims without some or all of these
specific details.
[0029] Electrical power systems for crash helmets are described.
Various devices, components, and systems using electrical power may
be implemented. In keeping with various embodiments described
herein, electrical power may be supplied from a power cell or
battery to different devices, systems, or components integrated
with a helmet. These devices, systems, or components may be
manually or automatically activated using a switch coupled to a
power cell using various electrical leads, wires or connectors
("leads"). By implementing an electrical power system in a helmet,
external power sources and the need for external attachments or
hardware are eliminated, enabling features or enhancements to be
coupled to a helmet while using power drawn from a helmet
electrical power supply. Further, electrical power may be supplied
to related systems such as footwear, gloves, visors, hydration
packs, bicycle seats, bicycle bags, and other uses.
[0030] FIG. 1 illustrates an exemplary electrical power system for
a crash helmet. Here, helmet 100 is shown including shell 102,
visor 104, power cell 106, electrical leads 108, connector 110,
vent 112, and side vents 114. In some embodiments, shell 102 may be
implemented using materials such as plastic, metal, metal alloys,
composite materials (e.g., Kevlar), or other materials that provide
impact-resistant strength. Also, power cell 106 may be implemented
as a single power cell or as a series of power cells (i.e., a
battery), which may be used to store a DC charge when charged by,
for example, an AC (e.g., 110 V, 60 Hz) or DC (e.g., 12V) power
source. Power distribution from power cell 106 may also be
implemented by conducting current along electrical leads 108.
Electrical leads 108 may be implemented using copper, steel,
various metal alloys, or other types of electrically conductive
materials. In some embodiments, power cell 106 may also include
components such as a processor, switch, a ventilation fan and
motor, and other electrical or electronic devices. In other
embodiments, power cell 106 may be implemented using various types
of batteries (e.g., Lithium Ion, Nickel Cadmium, Nickel Metal
Hydroxide, and others). Additionally, connector 110 may be used to
couple, either directly or indirectly, power cell 106 to an
external charger or power inverter. A power charge or inverter may
be used to build, store, or discharge electrical energy stored in
power cell 106. An electrical charge may be provided from power
cell 106 along electrical leads 108 to various components, or
systems. Although not shown, an electrical switch (e.g., contact,
pressure, mechanical, electromechanical, or others) may be used to
allow electrical current to flow from power cell 106 to other
systems. Additionally, power cell 106 may be coupled to other
systems attached, coupled, connected, or formed in shell 102. In
some embodiments, features, enhancements, or other systems
providing lighting, communication, or information may be provided
in other parts of helmet 100.
[0031] FIG. 2 illustrates an exemplary electrical power system for
a crash helmet including a chinbar. In some embodiments, helmet 200
includes shell 202, visor 204, chinbar 206, power cell 208,
electrical leads 210, and connector 212. Here, chinbar 206 may be
implemented using various materials such as polystyrene, injection
molded plastic, or other plastic compounds of varying stiffness
material rigidity. Chinbar 206 may also be implemented as a single
piece or as multiple pieces and are not limited to the examples
described herein. Modifications to chinbar 206 may be implemented
using alternative materials and configurations other than those
discussed herein. For example, different materials, shapes,
material compositions, configurations, components, and other
modifications may be implemented. As an example, chinbar 206 may
include power cell 208 and electrical leads 210 secured within an
internal cavity or pocket. As part of chinbar 206, an exemplary
electrical power system such as those described herein may be
implemented to provide electrical power to other components
attached, connected, or coupled to helmet 200 without requiring an
external source of power or leads. Further, the need for wiring,
mounting, and mounting hardware for coupling an external power
source are eliminated. Additionally, numerous components may be
operated using power delivered by an electrical current from power
cell 208. Some components may include one or more ventilation fans,
heads-up display, lighting, communication systems (e.g., Bluetooth,
IEEE 802.11 standard-based wireless communications modules and
components), and others.
[0032] FIG. 3A illustrates an exemplary electrical power system for
a crash helmet coupled to a power supply. In some embodiments,
helmet 300 may be implemented using shell 302, visor 304, power
cell 306, electrical leads 308, connectors 310 and 312, supply lead
314, plug 316, and power outlet 318. Here, power cell 306 may be
charged and re-charged by plugging into a DC or AC power supply,
power inverter, charger, or other device such as power outlet 318.
In some embodiments, power outlet 318 may be a portable or
installed power source. In other embodiments, power outlet 318 may
be implemented differently.
[0033] Here, electrical current charges power cell 306, which may
used to provide an electrical current to other devices, systems, or
components in helmet 300. Although not shown, other devices,
systems, or components such as fans, fan motors, processors and
microprocessors, display systems, and the like may be included.
Connectors 310 and 312 provide a connection between power cell 306
and power outlet 318, enabling electrical current to flow between
components located at various endpoints of an electrical system
embedded in a helmet. In some embodiments, connectors 310 and 312
may be implemented using female-male connectors, snap, mechanical,
or other types of connectors. When connector 310 is not coupled to
connector 312, connector 310 may be inserted or tucked into a
pocket, cavity, or other restraining structure within chinbar or
cheek pad (not shown) to prevent it from catching on any passing
obstructions. Alternatively, electrical leads 308 and connector 310
may be detached from power cell 306 and stored separately. In other
embodiments, electrical leads 308 and connector 310 may be attached
to another device, system, or component in helmet 300.
[0034] FIG. 3B illustrates an exemplary power system for a crash
helmet coupled to an alternative power supply. Here, helmet 300
includes shell 302, visor 304, power supply 306, electrical leads
308, connectors 310-312, supply lead 314, and charger 320. In some
embodiments, charger 320 may be used to provide a DC voltage to
charge or recharge power cell 306. Charger 320 may be implemented
as a single cell or multiple cell battery (e.g., LiOH, NiMH, NiCD,
and others), as a solar charger, power inverter, or as another
AC/DC charger. In some embodiments, supply lead 314 may be
detachable or hard-wired into charger 320. If hard-wired, charger
320 may be remotely, but proximally located to helmet 300. For
example, helmet 300 may be worn by a motorcyclist while charger 320
may be physically located elsewhere on a suit worn by the
motorcyclist or on the motorcycle. If a solar charger is used,
charger 320 may be worn on an external surface of helmet 300,
converting solar energy to electrical energy to provide a constant
charge to power cell 306. In some embodiments, charger 320 may be a
motorcycle battery (e.g., 12V DC) that, when connected via
connectors 310 and 312, supplies an electrical current to charge or
recharge power cell 306.
[0035] FIG. 4 illustrates an exemplary electrical power system
insert for a crash helmet. Here, system 400 includes pad 402, which
has cheekpad 404, power cell 406, electrical leads 308, connector
410, output leads 412, and light 414. In some embodiments, pad 400
may be fitted for half or three-quarter (3/4) helmets with no
chinbar. If no chinbar is included, power cell 406 may be
integrated, secured within, or formed into cheekpad 404. In other
embodiments, cheekpad 404 may be manufactured with a hollow pocket
having an opening for inserting power cell 406 inside. The
elasticity of material used to implement cheekpad 404 may be high
enough to permit the opening to be stretched to allow the passage
of power cell 406 to the cavity formed within cheekpad 404. In
other embodiments, power cell 406 may be inserted before, during,
or after manufacturing pad 402 and cheekpad 404. In still other
embodiments, power cell 406 may be implemented differently.
[0036] In some embodiments, power cell 406 may be used to provide
electrical current to additional devices, systems, or components
included with the electrical power system. For example, light 414
may be powered using an electrical DC voltage provided by power
cell 406. Power cell 406 may be a single or multiple cell battery
storing an electrochemical charge that, when output, provides a DC
voltage to light 414. In some embodiments, light 414 may be
implemented as an incandescent, light emitting diode, or other
light-emitting device. A switch (not shown) disposed between power
cell 406 and light 414 may provide a user with the ability to
control the light (i.e., activate, deactivate). In other
embodiments, light 414 may be replaced or supplemented with other
components such as a power or voice-activated wireless transmission
system for cellular or mobile phone communications, short-range RF
transceivers, camera or imaging device, display (e.g., heads-up
display), or other electrically-powered devices.
[0037] FIG. 5 illustrates an alternative exemplary electrical power
system for a crash helmet. Here, helmet 500 includes shell 502, pad
504, cheekpad 506, power cell 508, electrical leads 510, connector
512, output leads 514, and light 516. Here pad 504, which, in some
embodiments, may be similar to pad 402 described above in
connection with FIG. 4, may be inserted into helmet 500 and shell
502 as shown. Power cell 508, electrical leads 510, connector 512,
output leads 514, and light 516 may be configured in helmet 500 as
shown. If a half or three-quarters (i.e., the helmet varies in the
length of coverage or protection offered to the wearer) helmet is
used, light 516 may be slightly recessed into the side lining of
shell 502, providing a housed light that is under shell 502 but
able to illuminate a field of view. Additionally, the cone of
illumination provided by light 516 may also be adjusted in terms of
height, angle, lateral displacement, and other factors that may
provide efficient lighting for a person wearing helmet 500. In
other embodiments, different or additional devices, systems, or
components may be included in different positions or locations of
pad 504. As an example, light 516 may be included in the left
cheekpad of pad 504 while a camera may be included in the wearer's
right cheekpad. In law enforcement applications, light 516 provides
illumination without requiring burdensome physical activity by the
user while engaging in other activities (e.g., writing on a
notepad, observing or stopping a suspect while illuminating a dimly
lit vehicle, and the like).
[0038] Electrical current flows from power cell 508 to light 516
and other components. In some embodiments, a camera (not shown), or
other electrically-powered equipment may be coupled to shell 502,
pad 504 or other portions of helmet 500 without the need for an
external power source. In other embodiments, additional equipment
may be easily replaced by providing easily manipulated pads having
pockets, fasteners, locks, or other devices used to secure
equipment to pad 504.
[0039] FIG. 6 illustrates another alternative exemplary electrical
power system for a crash helmet. Here, helmet 600 includes shell
602, pad 604, right cheekpad 606, left cheekpad 608, power cell
610, electrical leads 612, connector 614, output leads 616, and
light 618. In some embodiments, helmet 600 may be a half or
three-quarter helmet, providing an electrical power system in
cheekpads or other liners such as right cheekpad 606 or left
cheekpad 608. An electrical power system may be used to provide
power to light 618. In other embodiments, power cell 610 may supply
power via output leads 616 to other systems such as a
microprocessor, wireless communications transceiver (e.g.,
Bluetooth, or another RF transmitter), heads-up-display, or other
electrical or electronic system. Some or all of these systems may
be included with helmet 600, which provides electrical power to
various systems from power cell 610, which is formed or placed
within an internal structure (e.g., left cheekpad 608) of helmet
600. In additional embodiments, a switch (not shown) may be
incorporated which provides a user with the ability to open or
close an electrical path to supply power to an electrically
connected or coupled system (e.g., light 618). Other variations may
be provided and are not limited to the embodiments described
above.
[0040] FIG. 7 illustrates another alternative exemplary helmet
electrical power system. In some embodiments, helmet 700 includes
shell 702, peak 704, neck curtain 706, strap 708, power cell 710,
electrical leads 712, switch 714, output leads 716, and light 718.
As an example, helmet 700 may be a law enforcement helmet worn such
as that worn by a police officer. An electrical power system for
helmet 700 may be installed in neck curtain 706. In some
embodiments, the electrical power system including, at least, power
cell 710, switch 714, electrical leads 712, and output leads 714,
may be implemented as part of neck curtain 706. Here, the left side
of neck curtain 706 includes power cell 710, switch 714, electrical
leads 712, and output leads 714. However, in other embodiments,
more or fewer components may be included. For example, in addition
to light 718, a camera or imaging device may be included. A
microprocessor, heads-up-display, or other electrical component may
be used, providing additional functionality installed in helmet 700
without requiring the use of external systems. In the context of
law enforcement applications, having systems such as power cell
710, switch 714, electrical leads 712, and output leads 716,
internal electrical distribution provides for ease of use and frees
the hands of the wearer to engage in other activities such as
handling different equipment while providing illumination from the
helmet at approximately the user's eye level. In some embodiments,
light 718, which may be set at eye level, provides for direct or
indirect illumination at a convenient height and direction for the
user. As a user moves, turns, or directs her vision, light 718
illuminates the field of view for the user without requiring the
user to direct or handle an external light, flashlight, or
illumination source. This may also be useful in contexts in
addition to law enforcement aspects, including military, emergency
services, and basic vehicle (e.g., motorcycle) operator safety. In
other embodiments, some or all of power cell 710, switch 714,
electrical leads 712, and output leads 716 may be implemented in a
different part of helmet 700 (e.g., right side of neck curtain 706)
and are not limited to the embodiment shown.
[0041] Other embodiments may include additional or fewer components
with the electrical power system that at least includes power cell
710, switch 714, electrical leads 712, and output leads 716. For
example, power cell 710 may be implemented as a single electrical
storage cell device or as a multiple cell storage device (e.g.,
battery) for electrical power. In still other embodiments, some or
all of power cell 710, switch 714, electrical leads 712, and output
leads 716 may be implemented in a liner, cranial pad, or other
internal structure within shell 702, providing an alternative
location other than neck curtain 708. Power cell 710, switch 714,
electrical leads 712, and output leads 716 may be located within,
for example, peak 704 or another related structure of helmet
700.
[0042] FIG. 8 is a block diagram illustrating an exemplary helmet
electrical power system. In some embodiments, system 800 may
include a battery module 802, light 804, display 806, memory 808,
processor 810, communications module 812, electrical bus 814, and
communications signal 816. Here, battery module 802 may also
include logic for controlling electrical power distribution to
other components in system 800. Battery module 802 may also provide
an AC or DC power to other components in system 800. In other
embodiments, there may be more, fewer, or different components
other than those shown in system 800.
[0043] The components shown in system 800 may be implemented using
various techniques and equipment. For example, light 804 may be
implemented using a light emitting diode (LED), fluorescent,
incandescent, or other type of bulb. In other embodiments, battery
module 802 may be implemented using a single or multiple cell
battery. In some embodiments, Lithium Ion, Nickel-Metal-Hydride, or
other fuel cell technologies may be used for battery module 802. In
other embodiments, display 806 may be implemented using a simple
back-lit display, a heads-up-display, an electrophoretic display, a
display built into a visor, or other variations as may be
envisioned. In other embodiments, processor 810 may be implemented
using a microprocessor (e.g., 32-bit, 64-bit, and others) for
processing control signals to control various components in system
800, including memory 808. For memory 808, various implementations
may be used to provide data storage for various purposes such as
power settings to extend or shorten the duration of use for battery
module 802, pre-determined settings for display 806, light 804
(e.g., light 804 may be pre-programmed using a program stored in
memory 808 and controlled by processor 810 to determine a
particular time of day or night as to when light 804 is activated),
and others. In other embodiments, processor 810 may process control
signals with communications module 812, which may be implemented
using various types of wireless (e.g., RF) communications systems
for either short-range (e.g., motorcycle-to-motorcycle,
unit-to-unit), cellular, or other mobile communications. In some
embodiments, systems installed on a motorcycle may be activated or
deactivated by control signals sent from processor 810 over
communications module 812. In some embodiments, control programs
stored in memory 808 may be used to control functions such as
activating a motorcycle headlamp when a low-level light environment
is detected. Power from battery module 802 distributed over system
800 provides flexible, safe, and efficient power distribution.
[0044] FIG. 9 is a circuit diagram illustrating an exemplary helmet
electrical power system circuit. Here, circuit 900 includes power
cell 902, switch 904, and lamp 906. Lamp 906 may be activated or
deactivated by closing or opening, respectively, switch 904. In
some embodiments, other circuit components may be included and
circuit 900 may be implemented differently, including various
circuit elements or components added in either series or parallel
configurations. In other embodiments, switch 904 may be coupled to
a wireless transceiver (not shown) that enables remote activation
and deactivation of electrical current to one, some or all circuit
elements.
[0045] FIG. 10 is a circuit diagram illustrating an alternative
exemplary helmet electrical power system circuit. In some
embodiments, circuit 1000 includes power cell 1002, motor switch
1004, motor 1006, lamp switch 1008, and lamp 1010. Here, motor 1006
may be activated or deactivated by closing or opening,
respectively, motor switch 1004. Likewise, lamp 1010 may be
activated or deactivated by closing or opening, respectively, lamp
switch 1008. In some embodiments, other circuit components may be
included and circuit 1000 may be implemented differently, including
various components in either series or parallel configurations. In
other embodiments, motor switch 1004 may be coupled to a wireless
transceiver (not shown) that enables remote activation and
deactivation of electrical current to one, some or all circuit
elements. In the above embodiments, variations may be performed to
enable local or remote control, using direct or indirect means
(e.g., wireless RF transceivers) for sending control signals to
activate or deactivate a switch (e.g., switch 904, motor switch
1004) or other elements of electrical power systems for helmets.
Different circuit configurations may be implemented by modifying
some or all of the circuit elements shown and described above.
Various implementations may be used and electrical circuit
configurations are not limited to those embodiments described
above.
[0046] FIG. 11 illustrates an angled perspective of an exemplary
electrical power system. Here, visor system 1100 includes connector
1102, switch 1104, electrical leads 1106, light 1108, camera 1110,
and visor 1112. In some embodiments, visor 1112 may be implemented
using materials such as plastic or other materials that provide
weather-resistant, structural strength. Visor 1112 may be
implemented to form different shapes, extensions, moldings, or
grooves to mount other systems, channel air or liquid (e.g.,
moisture, rain), flow, or to perform other purposes. In some
embodiments, extensions may be elongated portions of visor 1112,
including distal ends, formed grooves, and other shapes, features,
or structures associated with visor 1112. In other embodiments,
connector 1102 may be used to couple to an external power source
(not shown) and receive electrical current to flow to various
components or systems on visor 1112. Connector 1102 may be
attached, coupled, connected, formed, or integrated with visor
1112. For example, connector 1102 may be implemented at a distal
end of visor 1112. In addition, connector 1102 may be implemented
to attach, connect, or otherwise couple ("couple") to an external
system (e.g., a helmet system). Power distribution from connector
1102 may be implemented by conducting electrical current along
electrical leads 1106. Electrical leads 1106 may be implemented
using conductive materials such as copper, gold, steel, various
metal alloys, and other electrically conductive materials. As used
herein, the term "electrical leads" may refer to "conducting or
conductive medium" or "distribution system." In some embodiments,
electrical leads 1106 may be mounted, formed, fastened, attached,
or otherwise integrated ("integrated") with a bottom side (not
shown) of visor 1112. In other embodiments, electrical leads 1106
may be disposed within a channel (not shown) formed on the bottom
side of visor 1112, thus sealing electrical leads 1106 from plain
view. The channel ("conducting channel") may extend throughout
visor 1112 to house electrical leads that may be used to conduct
electrical current to other systems.
[0047] In some examples, switch 1104 may be implemented to control
electrical current to flow to various components (e.g., camera
1110). As used herein, the term "control" may refer to activating
and deactivating usage by allowing or stopping the electrical
current flow. In other embodiments, visor system 1100 may implement
another switch (not shown) to connect to another component (e.g.,
light 1108) integrated with visor system 1100. In one example,
visor system 100, when coupled to a helmet system (not shown), may
enable switch 1104 to be remotely manipulated. In addition, a
helmet system may be implemented with other systems, components, or
elements, including a communications system (e.g., wireless RF
transceiver) handling the control of visor system 1100.
[0048] In other examples, various components such as light 1108 and
camera 1110 may be integrated with visor 1112. In some embodiments,
there may be other components or systems integrated with visor
system 1100. Here, light 1108 may be operated using switch 1104 to
open or close a circuit to permit electrical current to flow from a
battery (not shown) to light 1108. In another example, light 1108
may be coupled to another switch (not shown) and provide a user
with the ability to control the light (i.e., activate, deactivate)
from a position other than that shown. In other embodiments, light
1108 may be implemented with a high-luminance, wide-angle, or
ultra-flux radiating light system (e.g., light-emitting diode).
Also, light 1108 may be integrated with a substantially flat
surface to illuminate in the direction of sight (i.e., a user's
field of vision). In addition, light 1108 may be implemented near
an edge of a substantially flat surface. In still other
embodiments, visor system 1100 may be implemented to integrate with
more than one light. Here, camera 1110 may be integrated with
moldings, extensions, or grooves of visor system 1100. For example,
camera 1110 may be implemented on one or more extensions to provide
a stable and level mounting surface. In addition, electrical leads
1106 may be implemented on various surfaces of visor 1112 (e.g., on
the bottom of) and extend throughout the extensions to provide
electrical current to camera 1110. In still other embodiments,
camera 1110 may be implemented to integrate with a substantially
flat surface of visor 1112. Other variations may be provided and
are not limited to the embodiments described above.
[0049] FIG. 12 illustrates a front perspective of an exemplary
electrical power system. Here, visor system 1200 includes switch
1204, light 1208, camera 1210, visor 1212, and antenna 1214. In
some embodiments, camera 1210 may include antenna 1214 to
communicate with other components or systems. Antenna 1214 may be a
communication device (e.g., wireless RF transceiver, Bluetooth,
IEEE 802.11, or others) configured to transmit images captured by
camera 1210. In other embodiments, antenna 1214 may be configured
to receive control signals to provide other operations (e.g., save
captured images, delete captured images, or others).
[0050] Here, switch 1204 may be implemented as described above in
connection with 1104 of FIG. 11. Switch 1204 may be implemented to
manipulate electrical current to flow to other components (e.g.,
camera 1210). In one example, visor system 1200 when coupled to a
helmet system (not shown) may configure switch 1204 to be remotely
manipulated. In addition, a helmet system may be implemented with a
communications system (e.g., wireless RF transceiver) handling
remote manipulation of visor system 1200. Various components such
as light 1208 and camera 1210 may be integrated with visor 1212.
Here, light 1208 may be implemented to operate with another switch
that provides the ability to control the light (i.e., activate,
deactivate). Light 1208 may be implemented as described above in
connection with light 1108 (FIG. 11). In other embodiments, light
1208 may be implemented using a light-emitting diode. For example,
a light-emitting diode may be white or another color variation.
Also, light 1208 may be implemented (i.e., mounted, coupled,
connected, or the like) near an edge of a substantially flat
surface. In still other embodiments, visor system 1200 may be
implemented to integrate with more than one light. In some
embodiments, camera 1210 may be implemented on extensions to
provide a stable and level mounting. Camera 1210 may be implemented
as described above in connection with camera 1110 (FIG. 11). In
addition, electrical leads 1106 (FIG. 11) may be attached, coupled,
connected, formed, or integrated with visor 1212 and extend
throughout extensions to provide electrical current to camera 1210
and light 1208. In other embodiments, visor system 1200 and the
above-described elements may be varied and are not limited to the
functions, structures, configurations, implementations, or other
examples provided above.
[0051] FIG. 13 illustrates a side perspective of an exemplary
electrical power system. Here visor system 1300 includes switch
1304, light 1308, camera 1310, visor 1312, and switch 1316. In some
embodiments, visor system 1300 may implement a switching system
that includes switch 1304 and switch 1316. Here, switch 1304 may be
implemented as described above in connection with switch 1104 (FIG.
11). For example, switch 1304 may be implemented (e.g., coupled,
mounted, connected) to camera 1310 and provide the ability to
control the flow of electrical current to or from camera 1310 or
other elements. In some embodiments, camera 1310 may be integrated
with visor 1312 by coupling to extensions, moldings, or grooves to
provide an elevated vantage point. In other embodiments, switch
1316 may be coupled to light 1308 by using electrical leads 1106
(FIG. 1) to electrically conduct between components. In some
examples, switch 1316 may be remotely operated when coupled to a
helmet (not shown). In other embodiments, visor system 1300 and the
above-described elements may be varied and are not limited to the
functions, structures, configurations, or implementations
provided.
[0052] FIG. 14 illustrates another side perspective of an
alternative electrical power system. Here, visor system 1400
includes switch 1404, light 1408, visor 1412, switch 1416, helmet
system 1420, light 1422, and light 1424. Here, visor system 1400
may be coupled, fastened, mounted, or otherwise attached
("attached") to helmet system 1420. In some embodiments, helmet
system 1420 may implement lighting, communications, or other
functionality that includes, for example, one or more lights being
implemented as described above in conjunction with light 1108 (FIG.
11). Helmet system 1420 includes light 1422 and light 1424 to
provide illumination in the vicinity of helmet system 1420. In some
embodiments, helmet system 1420 may implement an electrical power
system as described above in connection with system 800 (FIG. 8).
In still other embodiments, connector 1102 (FIG. 11) may be coupled
to helmet system 1420 to provide electrical current to visor system
1400. For example, connector 1102 may be connected to another
system within the lining of helmet system 1420. In addition,
electrical current may provide power to components or systems
located on visor 1412 such as light 1408, switch 1404, switch 1416,
and others. In other embodiments, visor system 1400 and the
above-described elements may be varied and are not limited to the
functions, structures, configurations, or implementations
provided.
[0053] FIG. 15 illustrates a side perspective of an alternative
electrical power system including a helmet and a visor. Here, visor
system 1500 includes switch 1504, light 1508, visor 1512, switch
1516, helmet system 1520, light 1522, and light 1524. In some
embodiments, helmet system 1520 may implement lighting,
communications, or other functionality that includes, for example,
one or more lights being implemented as described above in
conjunction with light 1108 (FIG. 11). In other embodiments, visor
system 1500 may be implemented as described above in connection
with visor system 1400. In still other embodiments, lights of
helmet system 1520 and visor system 1512 (e.g., light 1108 (FIG.
11), light 1522, light 1524) may be implemented using a variation
of colors including white. In addition, lights (light 1108 (FIG.
11), light 1522, light 1524) may be implemented as wide-angle,
ultra-flux light-emitting diodes. In still other embodiments, visor
1512 may be detached from helmet system 1520. In addition, visor
1512 may be coupled to helmet system 1520 using other components or
systems. Other variations may be provided and are not limited to
the embodiments described above.
[0054] FIG. 16 illustrates a front perspective of an alternative
electrical power system. Here, visor system 1600 includes switch
1604, light 1608, visor 1612, helmet system 1620, light 1624, and
light 1626. In some embodiments, helmet system 1620 may implement
one or more light-emitting diodes coupled to another switch (not
shown). One or more light-emitting diodes of helmet system 1620
(e.g., light 1624, light 1626) including light 1608 may be
configured to illuminate using white or another color. In various
embodiments, lights of visor system 1600 and helmet system 1620
(i.e., light 1608, light 1624, light 1626) may be configured to
illuminate in the direction of sight (i.e., a user's field of
vision). Here, switch 1604 may be disposed at a distal end of visor
1612. In some embodiments, visor system 1600 may be implemented as
described above in connection with visor system 1400 (FIG. 14).
Other variations may be provided and are not limited to the
embodiments shown and described above.
[0055] FIG. 17 illustrates a top perspective of an alternative
electrical power system. Here, visor system 1700 includes switch
1704, light 1708, visor 1712, helmet system 1720, light 1724, and
light 1726. In some embodiments, visor system 1700 may be
implemented as described above in connection with visor system 1600
(FIG. 16). Here, visor 1712 may be attached, coupled, or mounted on
helmet system 1720. Helmet system 1720 may be implemented using an
electrical power system such as that described above in connection
with system 800 (FIG. 8). Here, visor system 1712 may be
implemented to maintain a low-profile structure and compact
assembly of components or systems. As used herein, the term
"low-profile" may refer to an aspect, view, or configuration where
a structure (e.g., visor 1712, helmet system 1720, and others) has
a low (i.e., unsubstantial) cross-section, view, profile, or other
physical characteristic that has a low degree of exposure. Here,
switch 1716 may be configured to activate or deactivate (i.e., turn
on or turn off, respectively) light 1708. In other embodiments,
switch 1516 (FIG. 15) may be configured to handle switching of
electrical current to light 1708. Other lights belonging to helmet
system 1720 (e.g., light 1724, light 1726) may be integrated with a
helmet (e.g., helmet system 1720) having an electrical power system
as described above in connection with system 800 (FIG. 8). In other
embodiments, visor system 1700 and the above-described elements may
be varied and are not limited to the functions, structures,
configurations, implementations, or examples provided.
[0056] FIG. 18 illustrates another side perspective of a further
exemplary electrical power system. Here, visor system 1800 includes
switch 1804, light 1808, camera 1810, visor 1812, switch 1816,
helmet system 1820, and light 1822. In some embodiments, visor
system 1800 may be implemented as described above in connection
with visor system 1400 (FIG. 14). In other embodiments, camera 1810
may be integrated with visor system 1800 using mounting support
from formed moldings, extensions, or fixtures of visor 1812. As
used herein, the term "camera" may refer to "imaging system." For
example, helmet system 1820 may be attached to visor system 1800
and camera 1810 may be coupled to helmet system 1820 for added
stability. In addition, camera 1810 may be mounted on visor 1812 to
be facing in the direction of sight during usage (e.g., image
capturing). In some embodiments, camera 1810 may be attached (i.e.,
coupled) or detached to or from visor 1812. In other embodiments,
switch 1804, using electrical leads 1106 (FIG. 11) coupled to
connector 1102 (FIG. 11), may be configured to turn on or off
camera 1810. In still other embodiments, switch 1816 may be
configured to switch activation of camera 1810. In addition, lights
mounted on visor 1812 (e.g., light 1808) and helmet system 1820
(e.g., light 1822, light 1824) may be powered by an electrical
power system (e.g., system 800 (FIG. 8)) housed in helmet system
1820. Other variations may be provided and are not limited to the
embodiments described above.
[0057] FIG. 19 is a circuit diagram illustrating an exemplary
electrical power system circuit. Here, circuit 1900 includes
resistors 1902-1906, light sources 1912-1916, switch 1920,
connector 1922, and power cell 1924. Light sources 1912-1916 may be
activated or deactivated by closing or opening switch 1920.
Resistors 1902-1906 may have various resistance values, depending
on the respective light sources 1912-1916. For example, light
sources 1912-1916 may be light emitting diodes (LED). In some
embodiments, light source 1912 may be a white LED. In other
embodiments, light source 1912 may be a blue LED or a LED of a
different color. In still other embodiments, light sources
1912-1916 may be implemented using LEDs, fluorescent, incandescent,
halogen, or other light-emitting devices. Although three light
sources are shown in FIG. 19, in other embodiments, there may be
more or fewer light sources in circuit 1900. In still other
embodiments, additional accessories (e.g., high-powered flashlight,
cell phone, MP3 player, and others) may receive power from power
cell 1924. Power cell 1924 may be implemented using a single or
multiple cell battery. Power cell 1924 may be rechargeable. In some
embodiments, power cell 1924 may be a rechargeable battery. In
other embodiments, Lithium Ion, Nickel-Metal-Hydride, or other fuel
cell technologies may be used for power cell 1924. Connector 1922
may be configured to provide electrical energy from power cell 1924
to circuit 1900. In some embodiments, power cell 1924 may provide a
DC or AC voltage to activate circuit 1900. In contrast to using a
regular battery-powered light source (not shown), in which the
light may become dim or non-functional over time (e.g., during an
extended bicycle ride), the steady current of circuit 1900 ensures
that light sources 1912-1916 remain steady in brightness and do not
dim during use. In some embodiments, other circuit components may
be included and circuit 1900 may be implemented differently,
including various components in either series or parallel
configurations. In other embodiments, switch 1920 may be coupled to
a wireless transceiver (not shown) that enables remote activation
and deactivation of electrical current to one, some, or all circuit
elements. In the above embodiments, variations may be performed to
enable local or remote control, using direct or indirect means
(e.g., wireless RF transceivers) for sending control signals to
activate or deactivate a switch (e.g., switch 1920) or other
elements of electrical power systems for visor systems. Different
circuit configurations may be implemented by modifying some or all
of the circuit elements shown and described above. In other
examples, circuit 1900 and the above-described elements may be
varied and are not limited to the functions, structures,
configurations, implementations, or examples provided.
[0058] Although the foregoing embodiments have been described in
some detail for purposes of clarity of understanding, the invention
is not limited to the details provided. There are many alternative
ways of implementing the invention. The disclosed embodiments are
illustrative and not restrictive.
