Abstract
Movement of an animal into a barrier region is inhibited by fitting on the animal a collar carrying a housing including battery powered circuitry for transmitting a magnetic induction wave. A compressional wave emitter in the region responds to the magnetic induction wave to emit a compressional wave that the animal senses and which inhibits its movement into the region.
