Abstract:

A system for controlling an animal includes a radio signal receiver unit which is attached to the animal. The receiver includes an antenna assembly, a resonant filter, an amplifier, and a transducer for applying a motivational stimulus to the animal. A microcontroller selectively activates the components of the receiver according to a control sequence. The microcontroller performs a multi-stage authentication procedure in order to determine the presence of characteristic properties of the received signal prior to operating the transducer. The transducer includes a speaker circuit for applying audible stimulation, and a transformer circuit for applying electrical stimulation. The type of stimulation and the duration of stimulation may be selected according to control parameters used in conjunction with the control sequence.
