Abstract

Apparatus and system for training an animal to remain confined in a prescribed area defined by an electrical wire conductor through which A.C. current is passed. A receiver is used having two coils disposed at substantial right angles to each other and includes a control circuit for applying a high voltage to the animal in the form of an electrical shock when the signals induced in the coils are related to each other in a given proportion corresponding to a predetermined distance between the animal and the wire conductor.

Claims

1. Apparatus for training an animal to remain confined to a predetermined area defined by the location of an electrical conductor through which an AC current is passed comprising a receiver having a first and second coil tuned to the magnetic field generated around the conductor with each coil substantially disposed at right angles to each other, control signal means for comparing the signal strength in said first and second coil and means responsive to said control signal means for generating a high voltage and applying said voltage as an electrical shock to said animal when the signals induced in said first and second coil are related to each other in a given proportion corresponding to a predetermined distance between the animal and the electrical conductor.

2. Apparatus as defined in claim 1 wherein said electrical conductor is an electrical wire and wherein said receiver is affixed to said animal.

3. Apparatus as defined in claim 2 wherein said electrical conductor is laid out in a closed loop in series circuit with a source of AC power for passing AC current through the conductor and for generating said magnetic field with said closed loop forming a predetermined geometry defining said predetermined area.

4. Apparatus as defined in claim 3 wherein said control signal means comprises amplifier means coupled to each coil and a comparator circuit for comparing the amplified signal generated from each coil.

5. Apparatus as defined in claim 4 wherein said means for generating a high voltage comprises a square wave generator, a high voltage inverter and a transformer.

6. Apparatus as defined in claim 4 wherein said electrical conductor is laid out around a house with the conductor interwound along the front walk of the house.

7. A system for restricting the movement of an animal to within a defined area comprising:

means for generating a magnetic field about the perimeter of the area in which the animal is to be confined, means for sensing the magnetic field strength at a given location relative to said perimeter;

means responsive to said magnetic field at said location for generating a high pitched sound audible to said animal and means for increasing the pitch of said sound as the animal moves closer to said perimeter, comprising means affixed to said animal for generating an electric shock at or close to said perimeter, wherein said means for sensing the magnetic field strength comprises a pair of coils disposed substantially transverse to each other and control signal means for comparing the signal strength induced in each coil.
