Abstract

A position monitoring system having a position finder subsystem connected via a cellular telephone to a central monitoring station, a receive/transmit device carried with the position monitoring subsystem. A remote personal signalling subsystem comprising an RF coder modulator for transmitting a coded RF signal, and operating switch for activating the RF coder modulator. A receiver/transmit device is carried with a position monitoring subsystem for receiving the coded RF signal, decoding same and transmitting a coded RF acknowledgement signal. The remote personal signalling subsystem includes an RF decoder and demodulator for receiving and decoding the coded RF acknowledgement signal and a tactile signalling device is operated by the RF decoder and demodulator upon receipt of the coded RF acknowledgement signal and provides a tactile signal to a user that the RF coded signal had been properly received by the position finding subsystem. The transceiver is carried by the position finding subsystem is connected to the central monitoring station and the sending coded RF acknowledgement signal is controlled by central monitoring station.
