1. In a monitoring system for reporting the presence of an incarceree at a remote location, the system havinga central office with a central telephone,a remote telephone at said remote location,means for establishing a telephone link between the central telephone and the remote telephone,means associated with said remote telephone for generating a verification signal, andmeans associated with said central telephone for recognizing said verification signal,means for identifying the incarceree, comprising:
- an incarceree identifier, attached to the incarceree with an electrical component having a selected electrical characteristic;
a comparator circuit associated with said remote telephone for generating a comparison signal;
a reference electrical component connected with said comparator circuit and having an electrical characteristic which matches the selected electrical characteristic of the incarceree identifier electrical component;
means for connecting said incarceree identifier with said comparator circuit to compare the electrical characteristics of the identifier and reference electrical components; and
means responsive to said comparison signal from said comparator circuit for triggering said verification signal generating means when the characteristic of said incarceree identifier electrical component matches the electrical characteristic of the reference component,wherein the remote telephone includes a tone generator actuated by said means responsive to said comparison signal from said comparator circuit and providing a verification signal transmitted to said central office over said telephone link, andwherein said means responsive to said comparison signal from said comparator circuit includes a timer, and having a switch connected to an output of the timer, the switch actuating the tone generator to provide the verification signal.

Abstract
An incarceree identifying circuit used in an incarceree monitoring system includes an incarceree identifier worn by the incarceree at a remote location with an electrical component having a selected electrical characteristic. A comparator circuit measures the selected electrical characteristic and compares the selected electrical characteristic to a reference electrical characteristic. The comparator circuit triggers a timer if the selected electrical characteristic matches the reference electrical characteristic. The timer provides a signal to a speech circuit to disable a speaker. The tone generator is responsive to the signal and provides a verification signal via a telephone link to a central station. A verification circuit at the central location receives the verification signal and determines the presence or absence of the incarceree at the remote location.
