A control device, and method, for controlling the location of an animal

摘要

A control device and method is taught for controlling an animal's location. A GPS receiver receives GPS signals and a processor determines the position, velocity and heading direction of the animal relative to a target. A stimulus unit selectively applies a stimulus to the animal in response to received signals. A processor is programmed such that if the position of the animal relative to the target is less than a predetermined distance and the animal's velocity relative to the target is within a predetermined range and the heading direction of the animal is within a predetermined orientation relative to the target, then a signal indicative of applying a non-aversive stimulus to the animal is generated, and a signal indicative of removal of a non-aversive stimulus is selectively generated when the animal's velocity relative to the target is outside of the predetermined range, or the heading direction of the animal changes by more than a predetermined amount, otherwise a signal is generated indicative of first removing the non-aversive stimulus followed by application of an aversive stimulus to the animal.
