Patent ID: 7252051

Claim:
A collar-mounted electronic apparatus for control of barking by a dog, comprising: (a) a housing supported by a collar for attachment to the dog's neck; (b) first and second stimulus electrodes in contact with the dog's skin are connected to a surface of the housing for applying aversive stimulus control signals to the dog's neck; (c) a vibration sensor supported by the housing in contact with the dog's neck for sensing vibrations and generating vibration signals in response to vocalizing by the dog; (d) a controller in the housing having an input coupled to receive the signals produced by the vibration sensor, (e) a motion detector mounted in said housing and connected in substantially fixed relationship to the housing for producing a neck motion detection signal in response to a characteristic neck movement of the dog that characteristically accompanies barking by the dog; (f) the controller including output terminals for producing aversive stimulus control signals and having an input coupled to receive the neck motion detection signal and operative in response to the neck motion detection signal and signals from the vibration sensor to enable the controller to produce the aversive stimulus control signals; and (g) circuitry coupled to the controller to produce the aversive stimulus signals between the first and second stimulus electrodes in response to the aversive stimulus control signals.
