Abstract: An optical data communication and location apparatus for at least one location in a facility having at least one receiver at said at least one location. A plurality of portable transmitters provides optical wireless data links with the receiver. Each of the transmitters has a power supply with circuitry for transmitting data packets over said optical wireless data links to the receiver. The circuitry for transmitting data packets generates a data code having at least two time frames, each of the at least two times frames being divided into at least two data time slots. Each frame has exactly one pulse in one data time slot whereby in each data packet, there is encoded n-bits of binary data where 2 is equal to the number of time slots in each frame.

Abstract: Signaling and communication system in a hospital in which a plurality of master stations (24) transmit and receive data and audio signals with a plurality of remote stations (18-22) on a plurality of buses (BUS 0 - BUS 7) through a central station (16). The central station (16) includes a microprocessor (27), BUS I/O (28), and MASTER I/O (29) for selecting master and remote stations in a predetermined sequence. Master stations and buses are selected with a plurality of multiplexers and remote stations on a common bus are selected with a unique address. The multiplexers sample audio signals to provide pulse amplitude modulation.
