Abstract
A locator system has a plurality of locator transmitters, each transmitter transmitting a unique locator signal. Paging devices are carried by each user of the locator system and each paging device includes: (i) a receiver responsive to signals broadcast from the locator transmitters, (ii) a unique identification code stored therein, and (iii) a signal transmitter and controller for controlling the signal transmitter, the controller causing the transmitter to transmit location and identification signals based upon the locator signal received by the receiver and the unique identification code. A receiver is responsive to the signals transmitted by the signal transmitters in the paging devices and a control system handles communications from other parties to the users. The control system is coupled with the receiver and responsive to received location and identification signals to determine where to direct communications from other parties intended for a user.
