Abstract

A system provides for radio frequency detection of an offending device within a specific range of a body worn device. Upon detection of the radio frequency signal, the body worn device communicates to an infrastructure to alert of the presence and optionally the location of the radio frequency signal, and therefore the offending device. The user and/or location of the body worn device is/are revealed and the source of the radio frequency signal is readily determined for confiscation of the offending device. Other features include locating/tracking of the body worn device (and wearer) detection of tampering with the body worn device, and detection of cloaking of the body worn device (e.g. submerging in water or covering with aluminum foil, etc.).

First claim

What is claimed is:

1. A system for detecting radio frequency emitting devices, the system comprising:
at least one base station, the base station including a base station processor and a base station transceiver, the base station transceiver operatively coupled to the base station processor;
a plurality of body worn devices, each body worn device comprising a processor, a transceiver operatively coupled to the processor, a radio frequency detector, the radio frequency detector…
