ABSTRACT:
A remote animal training apparatus includes a portable transmitter with controls for selecting various degrees of electrical stimulation applied by means of a pair of electrodes protruding from a collar-mounted receiver-stimulator unit to the skin of an animal. The described receiver unit includes three oscillatory circuits for producing a low, medium and high number of pulses per second of the electrical stimulation in response to low, medium, and high frequency selection signals from the remote transmitter. The receiver-stimulator unit includes an output transformer having a secondary winding with terminals connected to the electrodes and primary windings driven by a switching circuit that drives predetermined current pulses through the primary winding at the selected number of pulses per second. The open circuit voltage produced across the electrodes remains at a high predetermined level regardless of the degree of electrical stimulation selected, thereby ensuring adequate coupling of electrical current to the animal's skin despite any variations in electrode positioning relative to the skin of the animal as it moves about.
