Abstract

A house arrest monitoring system that automatically verifies the presence or absence of prisoners, patients or other personnel who are required to remain at a prescribed location or to report to the prescribed location at a certain time. The system includes an identification tag that is worn by the individual being monitored. This tag transmits an identification signal that includes a unique identifying code, as well as status information that indicates whether the tag has been removed from near the flesh of the individual being monitored. The tag is totally self-contained and includes circuitry to sense when the tag is held near the flesh of the individual, as well as code generating and transmitting circuitry to periodically generate and transmit the identification signal. A field monitoring device (FMD) is included at the prescribed location to receive and process the identification signal, and to communicate with a central processing unit (CPU) located at a remote central monitoring location. The CPU is able to communicate with a large number of FMD's located at diverse field locations.
