  • Patent number: 5815077
    Abstract: A device for locating and training an animal includes a hand held transmitter and a multi-function electronic collar assembly to be worn by the animal. The electronic collar assembly includes a receiver for receiving signals from the transmitter. A microprocessor connected to the receiver processes the signals and is connected to a sounder, a sound sensor, a electroshock stimulator, and a motion sensor mounted on the collar. The transmitter can program the collar assembly and command it in one of several modes or functions for locating and training the animal. In the locating or sounder mode, the sounder emits humanly audible sounds to indicate the location of the animal. In one training mode, the sound sensor detects when the animal is making undesirable noises, such as barking, and the microprocessor has the stimulator deliver a shock to the animal for barking control.
