  • Patent number: 5548637
    Abstract: An automated position location system is provided which, in response to a telephone caller's inquiry and without human intervention, connects the caller directly to the telephone extension located nearest the individual or object of interest. A transmitter is attached to each individual (or object) to be monitored within a building. A number of stationary receivers are positioned at designated locations throughout the building. When a transmitter is transported within range of a receiver, information about the transmitter's identity and the receiver's location is provided to a tracking system, which calculates the transmitter's location and stores its identity and location in a chronological database. As the transmitter is transported throughout the building, the tracking system continually updates transmitter location information in the database.
