Title
(EN) POSITION ENHANCED CELLULAR TELEPHONE SYSTEM
(FR) SYSTEME AMELIORE DE CONTROLE DE POSITION DANS UN TELEPHONE CELLULAIRE
Abstract
(EN)
A position monitoring system having a position finder subsystem connected (46) via a cellular telephone to a central monitoring station, a receive/transmit means 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 is carried with said position finding subsystem for receiving the coded RF signal, decoding same and transmitting a coded RF acknowledgement signal. The remote personal signalling subsystem including 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 carried by the position finding subsystem is connected to the central monitoring station and sending said coded RF acknowledgement signal is controlled by said central monitoring station.

Système de contrôle de position possédant un sous-système de repérage de position relié (46) par l'intermédiaire d'un téléphone cellulaire à une station de contrôle centrale, ainsi qu'un émetteur-récepteur. Un sous-système de signalisation personnelle à distance comprend un modulateur codeur de radiofréquence servant à émettre un signal codé de radiofréquence, ainsi qu'un commutateur servant à mettre en fonction ledit modulateur. Ledit sous-système de repérage de position porte un émetteur-récepteur servant à recevoir le signal codé de radiofréquence, à décoder ledit signal et à émettre un signal d'accusé de réception codé de radiofréquence. Le sous-système de signalisation personnelle à distance comprend un décodeur de radiofréquence et un dispositif tactile de signalisation est mis en fonction par le démodulateur décodeur de radiofréquence à réception du signal d'accusé de réception codé et produit un signal tactile indiquant à l'utilisateur que le signal codé de radiofréquence a été reçu correctement par le sous-système de repérage de position. L'émetteur-récepteur porté par le sous-système de repérage de position est relié à la station de contrôle centrale et l'envoi dudit signal d'accusé de réception codé est commandé par ladite station.
