Remote infrared transceiver and method of using same |
摘要 |
The optical transceiver includes a headset antenna assembly, which is adapted to be worn on the head of the user, and which is connected electrically by a cable to a transceiver unit adapted to be worn on the belt of the user. The headset antenna assembly includes a set of alternating light emitting diodes and photosensitive diodes which are disposed on the antenna assembly to transmit and receive optical signals about a substantially 360 degree radial axis. The light emitting diodes are inclined upwardly from a horizontal plane to help avoid obstructions. Baffles are disposed between the diodes to reduce feedback interface, and a circuit in the transceiver unit discriminates against background light.
