<p>A system for controlling an animal (14) includes a radio signal receiver (10) attached to the animal (14). The receiver (10) includes an antenna assembly (30), a resonant filter (32), an amplifier (34), and a transducer (40) for applying a motivational stimulus to the animal (14). A micro-controller (U1) selectively activates the components of the receiver (10) according to a control sequence. The micro-controller (U1) performs a multi-stage authentication procedure in order to determine the presence of characteristic properties of the received signal (50) prior to operating the transducer (40). The transducer (40) includes a speaker circuit for applying audible stimulation, and a transformer circuit for applying electrical stimulation. The control parameters can be initially selected and/or downloaded to the microcontroller (U1) from an external programming device. The microcontroller (U1) stores data pertaining to the operation of the receiver (10) and can provide the stored data to an external device in response to an interrogation signal.</p> |
