  • Remote controlled animal training system
    Patent number: 6170439
    Abstract: An animal is trained using a remote transmitter and a collar-mounted receiver carried by the animal by selecting one of a plurality of desired stimulus levels by a stimulus level control of the transmitter. Information representative of the selected desired stimulus level is transmitted to the receiver and demodulated to produce a digital signal representative of the selected stimulus level. A microprocessor in the receiver operates to generate as an output a first stream of pulses of constant duration at a frequency representative of the selected stimulus level. The first stream of output pulses is filtered to produce a second stream of pulses the widths of which are representative of the selected stimulus level.
