CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation-in-part of application
Ser. No. 10/997,421, filed Nov. 23, 2004, which claims priority
pursuant to 35 U.S.C. .sctn. 119(e) to U.S. Provisional Application
No. 60/524,595, filed Nov. 24, 2003, which applications are
specifically incorporated herein, in their entirety, by
reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to articles or accessories
that incorporate electronic circuitry, and more particularly, to
articles or accessories with circuitry for alerting the wearer to
the presence of a wireless communication signal such as generated
by a mobile telephone.
[0004] 2. Description of Related Art
[0005] Mobile telephones and similar wireless communication devices
are in widespread use today. Such telephones typically employ an
audible signal, such as a ring tone, to alert the user of incoming
calls. Other signals, such as vibratory alerts, may also be
employed for this purpose. A signal such as a flashing light may
also be used, but is not useful when the mobile telephone is
carried so as to render a light invisible to the user, such as in a
pocket, purse or other receptacle, or otherwise out of a user's
line of sight.
[0006] In addition, the use of audible or vibratory signals is
discouraged or prohibited in many circumstances. For example, in
classrooms, meetings, movies and other quiet environments, users of
mobile phones may desire or be required to turn off audible or
vibratory alerts. In other environments, for example in a dance
club, at a concert, or factory floor, the mobile phone user may be
too distracted by noise or other activity to notice an audible or
vibratory signal. Either way - if the phone signal is turned off or
simply not noticed by the user - incoming calls may be missed or
unintentionally ignored.
[0007] Compact circuitry for illuminating a light, such as an LED,
in the presence of an wireless communication device is known in the
art. Such circuitry has been incorporated, for example, in the body
of a pen. Lacking the more complex processor of the mobile
communication device, prior-art compact wireless alert circuitry
will react to the presence of any wireless signal within its range
of sensitivity. Therefore, a device equipped with the circuitry
will alert the user not only when the user receives a call, but
also anytime a mobile telephone within its range of sensitivity is
in use. Generally, such non-specific sensitivity is undesirable. On
the other hand, if the circuitry is not sufficiently sensitive, it
will fail to sense an incoming call even if the user's mobile phone
is only a short distance away, such as in a nearby purse. In other
words, it is desirable to provide a signaling device that will be
activated by the user's own cellular phone but not others.
[0008] In this regard, a "personal space" may be defined as a space
in which the user's own mobile communication device will usually be
the only device present. For example, a personal space for a
person's body may be defined as the space within about three feet
of the person's body, whereas a personal space for a user's room or
home may be larger. Within the applicable personal space, it should
be possible to use less expensive non-specific alerting circuitry
(i.e., circuitry responsive to signals from different mobile
communication devices), without responding to most or all signals
from mobile communication devices other than the user's. For
example, with a fashion accessory designed to be placed on or near
the user's body, sensitivity to about three feet away, but not
substantially beyond three feet, should usually be compatible with
the user's personal space. It is desirable, therefore, to control
the sensitivity of non-specific alert circuitry to respond to
mobile communication devices placed within a defined distance of
the alert circuitry.
[0009] An alert circuit's sensitivity to wireless signals is at
least partially determined by the dimensions and configuration of
its connected antenna for the wireless signal. For example, if the
antenna is too short, it will not be sufficiently sensitive, and
will not reliably pick up signals from the user's telephone. If it
is too long, it will be too sensitive, picking up signals from too
large an area. It may be difficult to accommodate an antenna of
suitable length and configuration many small articles. For example,
fashion accessories such as costume jewelry may often impose design
constraints that may make it difficult to accommodate a
suitably-sized antenna.
[0010] It is desirable, therefore, to provide articles of various
types for alerting the wearer to the presence of an incoming call
using a visual signal, such as a blinking or steady light. The
article should be configured to alert the user to a wireless
communication signal from a mobile telephone, pager or similar
device within the user's personal space. For example, the article
may be responsive within about a three-foot distance from a user's
cell phone, but not to signals from cell phones more than about
three feet away. The article may be small enough to wear or carry
as a portable, or may be designed to stay in a particular location,
such as a home, vehicle, bedroom, or office.
SUMMARY OF THE INVENTION
[0011] The present invention provides various articles or
accessories that overcome the limitations of the prior art.
Articles or accessories according to the invention may include, for
example, fashion accessories such as bracelets, brooches, clasps,
rings, anklets, necklaces or clips; wristwatches or other
timepieces, keychains, novelty items, belts, flashlights,
mini-lights, hats, eyeglasses, sunglasses, charms, clothing, purses
and handbags, desk sets, personal digital assistants (PDA's), and
cases. The articles and accessories may be designed for personal,
household, or vehicular use within a defined personal space of a
user.
[0012] By way of example, a fashion accessory according to the
invention may be configured as a single encasement, or a plurality
of encasements that are strung together in a bracelet, pendant,
necklace, brooch, or the like. One or more of the encasements
comprises an inner cavity that holds a compact sensor chip,
miniature battery, and LED integrated into an alerting circuit
module. An encasement may comprise, for example, a ornamental bead,
block or crystal, a housing for a timepiece, rubber or plastic
tubing, a decorative band, or the like. The bead or other
encasement is comprised at least partially of a transparent or
translucent material, such as plastic or glass, so as to transmit
light from the LED. The LED is configured to illuminate when the
sensor detects a wireless communication signal within the range of
frequencies and signal strength that it is sensitive to. Hence, the
case enclosing the alerting circuit module is conveniently referred
to herein as an "illuminated case." In this embodiment, the
illuminated case may be of any shape that is aesthetically pleasing
and wearable as a fashion accessory. The sensor chip is connected
to an antenna that is strung through one or more passive
(non-illuminated) beads or other decorative housing. Optionally,
the antenna may be used both as a mechanical structure for
stringing beads or other cases and as an antenna for the alerting
circuit module. A suitable antenna for personal jewelry may be, for
example, between about one inch and four inches in length.
[0013] Each illuminated case, alerting circuit module and its
associated antenna, optionally strung through a plurality of
passive beads or other structural or decorative housings, comprises
an alerting accessory module. A single accessory module may be
attached to any suitable structure for holding jewelry, for
example, a pin, clasp, or the like, to provide a fashion accessory
for alerting its wearer to the presence of a wireless communication
signal in the vicinity of the wearer. Two or more alerting
accessory modules may be strung together to form a bracelet,
anklet, pendant, necklace, or the like. Because wireless
communication signals are directional in nature, the combination of
two or more alerting accessory modules in a single fashion
accessory may increase the functionality of the accessory, by
increasing the probability that at least one of the modules will be
favorably oriented for sensing a nearby signaling telephone.
[0014] Advantageously, a fashion accessory according to the
invention may be made of suitably inexpensive materials, for
example, plastics or non-precious metals, so that the accessory may
be regarded as disposable, and simply discarded when the battery
life is spent. In the alternative, the illuminated case may be
designed to be opened after assembly, so that the alert circuit
module can be accessed for battery replacement.
[0015] Thus, a person wearing a fashion accessory will receive a
visual signal by illumination of the LED when her mobile telephone
receives an incoming phone signal. This may be used to alert the
user to an incoming call when the mobile phone alert is off or is
not loud enough to be heard in a noisy environment, or if in a
vibrating alert mode, is not in contact with the user. In addition,
some users may find that the illuminating accessories are
attractive and fun to wear, regardless of their other
functions.
[0016] The alert circuit may be adapted for use with a variety of
other personal articles. As with fashion accessories, other
personal articles may be designed having sensitivity to cellular
signals within a user's personal space. The size of personal space
may depend on the intended environment for the article. For
example, an article intended to remain in a user's private
residence or office may be designed for sensitivity to cellular
signals over a larger area. A desk set, for example, may be
sensitive to signals within a 20 foot radius for sensitivity within
an office space. A wall clock may be sensitive to signals over a
greater area, such as a 50 foot radius, for sensitivity within a
house. Greater or lesser sizes of personal space may also be
appropriate. To ensure that an appropriate personal space is
established for adequate sensitivity without oversensitivity to
extraneous signals, an article with alert circuitry may be provided
with a manual sensitivity adjustment.
[0017] A more complete understanding of the personal article with
wireless signal alerting device will be afforded to those skilled
in the art, as well as a realization of additional advantages and
objects thereof, by a consideration of the following detailed
description of the preferred embodiment. Reference will be made to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0050] The present invention provides an article or accessory with
a wireless alerting device for personal, household, or vehicular
use, that overcomes the limitations of the prior art. In the
detailed description that follows, like numerals are used to
indicate like elements appearing in one or more of the figures.
[0051] Referring to FIGS. 1 and 2, in an embodiment of the
invention, a fashion accessory 100 is configured as a bracelet.
Accessory 100 includes a first signaling assembly 102 connected to
a second signaling assembly 104 via an elongated member 106, for
example, a strap, cord, tube or chain. In the illustrated
embodiment, the elongated member comprises and is henceforth
referred to as an ornamented chain 106. Chain 106 is divided into
first and second portions 108, 110 by a central case 112. Clasps
portions 107, 109 may be provided at opposite ends of the
ornamented chain for forming a loop of the accessory 100. The
ornamental clasp depicted is merely exemplary, and any suitable
clasp may be used. First and second assemblies 102, 104 may be
substantially identical, each comprising an ornamented bead 118
holding a circuit module 120. The circuit module is configured to
activate a light-emitting diode (LED) when the presence of a mobile
communication signal from a nearby device is sensed. Circuit
modules for this purpose are known in the art. The LED may selected
so as to illuminate in any visible color (e.g., red, orange,
yellow, green, blue, indigo, violet and white) for which an LED is
available.
[0052] Each of the first and second signaling assemblies 102, 104
further includes an antenna 122 connected to circuit module 120. A
ring 121 or other retainer attached to case 130 may be used to hold
the antenna 122 and circuit module 120 in place, when the case is
opened replace the battery. Preferably, antenna 122 is selected to
have an end-to-end length and geometric configuration that is
appropriate for imparting the desired signal sensitivity to the
fashion accessory. Different antenna lengths and configurations may
be appropriate, depending on various factors, including, for
example, the characteristics of the mobile communication signal to
be sensed, the desired range of sensitivity, and the design of the
circuit module.
[0053] For personal use applications, it is generally desirable
that the signaling assemblies be sensitive to signals emanating
from a mobile communication device within about a three-foot
distance from the user. This distance should permit the fashion
accessory to respond to signals from the wearer's mobile
communication device, without responding to signals from other
devices that are not very near to the wearer of the fashion
accessory; i.e., within the user's personal space. Of course,
greater or lesser sensitivity to mobile communication signals may
also be selected.
[0054] For example, an extended, substantially linear antenna
length between about one to four inches is believed suitable for
jewelry designed for use with typical mobile communication devices
within the United States. Suitable materials for antenna 122 may
include one or more conductive wires, for example, single-strand or
multi-stranded wires of copper or aluminum alloys as known in the
art. In an embodiment of the invention, the antenna is comprised of
at least five copper wires entwined together for strength, then
coated with a flexible plastic material for added strength and
protection.
[0055] The antenna 122 should be configured to extend from the
circuit module 120 in a substantially linear configuration. To
accommodate the excess antenna length, a distal portion of the
antenna may be threaded inside or alongside the ornamented chain
106. A distal end 124 of antenna 122 may be anchored inside an
adjacent bead 112. In the depicted embodiment, the central bead 122
does not contain a circuit module, although it is of the same
design as beads 118. In the alternative, the anchoring central bead
112 may contain a circuit module with an LED signal, or may
incorporate an alternative design.
[0056] Anchoring collars or beads 126, or any other suitable
fastener, may be used to attach the distal ends 124 of antenna 122
to adjacent beads of accessory 100. For example, anchor 126 may be
crimped to the antenna wire and engaged with a holdfast in the
central bead 112. If the antenna is made of a sufficiently strong
material, antenna 122 may also serve as a structural connector for
stringing beads of the accessory 100. Stress may thereby be
relieved from chain 106, which consequently may be made lighter or
of weaker materials than might otherwise be possible. Chain 106 may
comprise a hollow interior extending from end-to-end, through which
the antenna may be threaded, as shown in FIG. 2. In the
alternative, the antenna may be strung at least partially along an
exterior of the connecting chain (not shown).
[0057] For a simpler look, the connecting chain may be omitted
entirely, and the connecting load may be borne entirely by the
antenna. In such case, the antenna may be used to string unlighted
ornamental beads between the lighted ornamental cases 118. In
addition, or in the alternative, the antenna may be strung inside a
plastic or rubber tube, or through a flat decorative band. The tube
or band may have an ornamental design, and/or may be inserted
through ornamental charms or beads. For a timepiece, the antenna
may extend from a central case in or adjacent to a wrist band or
carrying strap.
[0058] In addition to antenna length, sensitivity may also be
affected by antenna orientation. Fashion accessories may shift
frequently with movements of the users, and the orientation of the
antenna is unpredictable. To improve the probability that at least
one signaling assembly will be connected to a properly oriented
antenna, two or more independent signaling assemblies may be
combined in a single fashion accessory. For example, FIGS. 1 and 2
show a bracelet with two signaling assemblies 102, 104 each having
its own antenna. When configured as a bracelet with clasp portion
107, 109 engaged as shown in FIG. 1, the antennas connected to the
respective signaling assemblies 102, 104 will naturally tend to be
in different orientations.
[0059] FIG. 3 shows an enlarged view of an exemplary circuit module
120. The module comprises a semiconductor chip 132 containing the
logic for switching power to an LED 134 when antenna 122 receives a
sufficiently strong communication signal. Various suitable chips
are commercially available, and one of ordinary skill may devise a
suitable chip. The chip 132, LED 134, and any other necessary
components such as resistor 138 may be mounted on a board 136. To
facilitate installation inside of a round bead, board 136 may be
circular in shape. A battery 140, which is also circular and has
approximately the same diameter as board 136, may be clipped to the
board using clips 142. The entire module 120 is compact and small
enough to fit inside the structural or decorative case of a fashion
accessory, such as inside an ornamental bead of the depicted
embodiment. For example, the module including the battery may be
about 0.25 inches thick and about 0.38 inches in diameter. Smaller
or larger sizes may also be used.
[0060] Beads 118 may be molded in two halves, and provided with an
interior compartment 128 for holding a circuit module 120. FIG. 4
shows a half 130 of an exemplary bead 118. To form a bead 118, half
130 may be mated with a complementary half (not shown). The bead
halves may be configured to permit disassembly and reassembly
without damaging the bead halves. This may permit servicing of the
circuit module enclosed in the bead, such as battery replacement,
if desired. Various plastic materials as known in the art for
fashion accessories may be suitable for beads 118. At least a
portion of the beads or other encasement 118 should be translucent
or transparent to transmit light from the circuit module 120 to an
exterior of the bead. In the depicted embodiment, beads 118 are
fashioned entirely of translucent materials.
[0061] FIG. 5 is a diagram of an exemplary alert circuit 200
according to the invention. Integrated circuit 202 comprises a
suitable chip as known in the art, having at least one input for
attaching an antenna, and providing at least one output for
activating an LED when an RF signal is picked up by an antenna
connected to the antenna input. In circuit 200, any suitable
antenna 204 as described herein may be attached to an input
terminal of chip 202. An LED 206 is attached across output
terminals of chip 202 and to ground. A suitable power source, such
as a battery 208, is attached to power terminals of the chip. For
example, battery 208 may comprise a 3 Volt lithium ion battery.
Optionally, a diode 210 may be placed in the circuit between the
power source and the chip, to prevent unintentional supply of power
having the wrong polarity.
[0062] Circuit 200 may be vulnerable to generating false alerts
from static interference picked up by antenna 204. For example,
motion of a wearer's body may cause RF pulses to be detected and
signaled by LED 206. To prevent such false alerts, a filter 212 may
be placed across the terminals of LED 206. Filter 212 may be
configured to absorb very brief pulses of energy to the LED,
thereby preventing it from illuminating in response to interference
picked up by antenna 204. When a more sustained RF signal such as
from a mobile communication device is picked up by the antenna,
filter 212 passes the resulting more sustained energy pulse from
chip 202, causing the LED to illuminate.
[0063] To configure filter 212, resistor 214 should be selected
based on the current and voltage required to illuminate the LED in
comparison to the current and voltage supplied by chip 202. It may
be advantageous to select a resistor having as much resistance as
possible, without noticeably impeding illumination of the LED. For
example, a resistor value in the range of about 100 .OMEGA. may be
suitable for many applications. Then, a capacitor 216 should be
selected based on the value of the resistor and the desired
filtering frequency. It may be advantageous to select a value for
capacitor 216 that is as small as possible, while still effectively
filtering out pulses having a frequency less than the desired
filtering threshold. One of ordinary skill may select suitable
values for resistor 214 and capacitor 216, based on the factors
described above.
[0064] Advantageously, a user need not make any modifications to
her cellular telephone or other communication device to make use of
an alerting accessory according to the invention. Circuit 200 may
be configured to receive signals within 800-1900 MHz on global
system for mobile communications (GSM) and time division multiple
access (TDMA) methods of digital wireless communications
transmission. When an incoming call is received using these
methods, the receiving device generates a return acknowledgement or
"handshake" as known in the art. The strength of the outgoing
handshake signal is strongest immediately adjacent to the antenna
of the cellular telephone, and diminishes with distance.
[0065] Circuit 200 may be configured to respond to the handshake
generated by the user's mobile phone. Hence, the user may be
alerted as to the presence of an incoming communication signal
without being required to carry the communication device. The
cellular telephone can be in a purse or backpack or anywhere else
within the user's personal space, and the circuit will indicate the
presence of an incoming call by illuminating the LED, such as by
flashing.
[0066] FIG. 6 shows an alert circuit 300 according to an
alternative embodiment of the invention. Circuit 300 comprises a
filter 312 similar to filter 212, but further incorporating a
plurality of NOR gates A-D, such as may be provided on a CMOS chip.
Gates A-C are wired as inverters, and gate D as a NOR gate.
Resistor R1 and capacitor C may be adjusted as previously described
to prevent the LED from illuminating in response to transient
noise. Resistor R2 is provided to allow capacitor C to discharge
when no signal is present, and should be selected to have a
resistivity much higher than R1.
[0067] FIGS. 7A-C show a fashion accessory 400 according to an
alternative embodiment, and certain details thereof. Accessory 400
comprises signaling assemblies 402, 404, which may be configured
similarly to assemblies 102, 104 previously described in connection
with FIGS. 1-2. For example, alert circuit modules as previously
described may be housed in separate encasements 418 that are
connected by respective elongated members 410, 408. An antenna may
be threaded through an interior of the elongated members 410 and
408, and anchored in a central encasement 412 in a manner similar
to accessory 100. In the alternative, or in addition, an antenna of
suitable length may be strung through the elongated member 415
connecting assemblies 402, 404.
[0068] Accessory 400 illustrates the use of an extended antenna 422
in connection with one or more elongated members 410, 412, 415 of
essentially tubular form as connecting members between signaling
assemblies, or for attaching to a personal article or clothing of a
user. For example, these members may comprise a structural or
decorative tubing material of any desired cross-section, including
but not limited to the smooth cylindrical tubing as shown. Other
suitable tubing may include, for example, flattened tubing,
hexagonal tubing, ribbed tubing, and so forth. Antenna 422 may be
configured to run through an interior portion of such tubing. In
the alternative, the antenna may be molded or formed in place with
the tubing material. In either alternative, most or all of any
exposed portion of the antenna may be encased by the tubular
member. If selected of sufficiently strong material, antenna 422
may provide a structural connection between adjoining signaling
assemblies 402, 404. In other respects, accessory 400 may be
configured similarly to accessory 100, and may be modified or
adapted in similar ways.
