  • Patent number: 5305132
    Abstract: A light frequency communications system and method of using the system is disclosed. The system includes a base station and a plurality of remote units wherein the base station and all the remote units communicate in a full duplex mode utilizing a single light wave carrier. Multiplexing between the units is accomplished by modulating an audio signal on at least one subcarrier frequency.

  • Patent number: 5253095
    Abstract: A stationary optical antenna forming a part of a full duplex optical communication system, includes optical emitter and receptor devices having peak power axes, and a mounting arrangement for positioning the devices at an elevated location within a room with their axes directed downwardly at a given angle to a horizontal plane, based upon the height of the devices above the floor, thereby enabling remote portable transceivers to be able to communicate therewith within the same room. Baffles help prevent interference between the emitters and receptors, and a compensation circuit is employed to enable the optical communication to take place, even in bright light conditions.

  • Patent number: 5027433
    Abstract: 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.
