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.
