Abstract
A pet confinement system includes a loop antenna for placement about the border of an area within which the pet is desired to be confined, a control panel for recording a voice command in the pet owner's voice, and means for generating an RF signal encoded with said prerecorded voice command for transmission over said antenna. A receiver is mounted to a collar for attachment to a pet such that as the pet approaches the antenna the pet owner's voice command is received from the antenna and announced to the pet to encourage him to withdraw from the border. A threshold level detector detects when the pet approaches even closer to the antenna and the collar includes a pair of electrodes for applying a shock to the pet to further reinforce the pet owner's voice command and convince the pet to withdraw from the border. The control panel further includes monitoring circuits for monitoring the integrity of the loop antenna and the AC power supply. If a break is detected in the loop antenna, or if the control panel switches to its included battery backup, a display provides a visual message and an announcement is made over a speaker in the control panel to alert the operator that a system failure has occurred.
