  • Electronic animal control system with masking signal generator
    Patent number: 5576694
    Abstract: A disruption generator is provided for use in an electronic animal confinement system for preventing undesirable correction of the animal in the vicinity of incidental conductive structures capable of coupling and re-radiating a transmitter signal for controlling the animal. The disruption generator produces a disruption signal for masking, preventing, or otherwise interfering with reception of the transmitter signal by an animal control receiver device mounted on the animal. The disruption generator can be connected to such incidental conductive structures as utility conduits, door frames, household wiring, and the like, to prevent undesirable correction of the animal in the vicinity thereof due to inductive or resonant coupling of the transmitter signal by such structures.
