Patent ID: 8006649

Claim:
Apparatus for providing an indication to a user that a stimulus has been provided to an animal, comprising: a receiver adapted to be worn by an animal, said receiver including a timer operative to provide a defined time interval; a monitoring circuit in the receiver, said monitoring circuit operative to generate a monitor signal in response to the valid detection of a radiated field from an antenna defining a restricted area for the animal, said valid detection of the radiated field being associated with the proximity of the animal to the antenna, said monitoring circuit further operative in response to the monitor signal to restart the timer; a stimulus generator in the receiver operative in response to the monitor signal to provide a stimulus to the animal in the form of an electric shock or an audible signal; and a monitor indicator operative autonomously in response to the monitor signal to provide an indication for a user that the stimulus has been provided to the animal, said indication extending substantially for the defined time interval and extending substantially beyond the occurrence of the stimulus.
