Abstract
Abstract Entry of a pet into a barrier region is deterred by emitting beams of compressional wave pulses from plural above ground sites in the region. The pet wears a collar with at least one transducer for converting the compressional wave beams into electrical signals. In response to pulses of the compressional wave energy being transduced, (1) an aural sound in a frequency range which can be heard by the pet is derived by a second transducer on the collar and (2) an electric shock is selectively applied to the pet by electrodes on the collar.

Claims Analysis
Total Claims: 35
Claim 1
Independent Claim
69 words
A method of deterring entry of an animal into a barrier region comprising emitting a beam of radiant wave energy from an above ground source in the region, receiving the emitted radiant energy beam at the animal, and in response to receipt of the radiant wave energy in the beam at the animal, applying to the animal a stimulus tending to prevent entry of the animal into the beam.
Claim 2
Independent Claim
69 words
A method of deterring entry of an animal into a barrier region comprising emitting a beam of radiant wave energy from an above ground source in the region, receiving the emitted radiant energy beam at the animal, and in response to receipt of the radiant wave energy in the beam at the animal, applying to the animal a stimulus tending to prevent entry of the animal into the beam.
