A
wireless ad hoc pico network is formed by
eyewear and other devices such as a computer, a bracelet and a telephone having similar transceivers mounted on them.
Master slave relationships are configurable. Other devices, such as a radio, a
CD player, a
hand held global positioning
satellite system and a
heart rate monitor, having similar transceivers, can also be connected with the
transceiver of the
eyewear. The transceivers operate on globally available, unlicensed radio band, 2.45 gigahertz (GHz) and conforms to the
Bluetooth standard. The
power consumption of
Bluetooth enabled devices is less than three percent of the
power consumption of a
mobile phone. The
eyewear includes a frame and connected to the frame are two temples. Temples are connected to frame via hinges. Temples have a male portion of a connector incorporated in them. Female portion of the connector is made integral with the hinges. When the male portion is inserted in the female portion the temple is attached to the frame. The temples can be removed by pulling the connector apart, and a temple with different apparatus within it can be inserted in place of the removed temples. The temple may have co-molded within its body, an apparatus such as an audio device, a camera, a speaker, and a
microphone, and a
display device such as
liquid crystal or an alarm. In another embodiment, eyewear constitutes a distance alarm to monitor the movement of, for example, a child. A device in form of, for example, a bracelet is worn by the child. The transceivers in the eyewear and the bracelet form a small-range
wireless network, i.e.,
piconet, wherein the eyewear and the bracelet communicate using signals conforming to the
Bluetooth technology. The
transceiver in the eyewear is configured to generate an alarm when the bracelet exceeds a predetermined distance from eyewear.
