First Claim
1. A proximity monitoring system for detecting and individually identifying the proximity of any object or person from a group of objects or persons, and comprising:
- a central information processor, and processor signal receiver means connected thereto;
a plurality of remote detector modules adapted to be placed in various locations at a distance from said central information processor, each module having a module first transmitter means for communicating with said processor signal receiver means and having a module second transmitter means operable to emit a standard, uniform "switch-on" signal for communicating with any object or person to be identified in said group, in the immediate proximity of said module, and module receiver means for receiving a signal from any object or person to be identified in the immediate proximity of said module,a plurality of individual personalized portable identifier units adapted to be associated with each said object or person in said group, each identifier unit comprising a continuously activated identifier receiver adapted to receive said uniform "switch on" signal when in the immediate proximity of any of said remote detector modules, a coded signal identifier transmitter which is normally de-activated, a battery power means, and switch means operated by the identifier receiver in response to any said uniform "switch on" signal from any said module second transmitter means of any of said remote detector modules when said identifier unit is in the immediate proximity of said module to connect said battery power means to said identifier transmitter thereby activating same for emitting a personalized coded identification signal to said module receiver means of said module; and
,said module receiver means being operable, in response to a said coded identification signal, to cause said module first transmitter means to transmit a coded information signal to said processor signal receiver means, and,and said processor signal receiving means being operable, in response to said coded information signal from said module first transmitter means, to cause said central information processor to process information corresponding to said coded information signal.
