Abstract

An open-loop internal monitoring system includes a plurality of internal radio transmitters, a plurality of external radio receivers, and a central processor for alerting a system monitor if a subject is outside a predetermined unauthorized location, the central processor being connected to the external radio receivers by relays. The open-loop system may alternatively include a substance monitoring unit. A closed-loop internal monitoring system for controlling one or more transmission parameters of the internal radio is also provided, the closed-loop system further including an external radio transmitter for transmitting a command relayed from the central processor and internal radio receivers for receiving the command. A closed-loop internal monitoring and behavior control system uses a behavior control unit having a stimulating electrode or chemical micropump for producing an adverse reaction within the subject upon receipt of a command from the central processor.
