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.
