Electronic confinement system for animals using modulated radio waves
First Claim
1. An animal confinement arrangement comprising:
- home base transmitting means for transmitting a digitally encoded signal from a first signal-emitting wire, the first signal-emitting wire disposed around a confinement area and the digitally encoded signal containing a specified digital signal;
receiver means for receiving the digitally encoded signal;
means for removing the specified digital signal from the digitally encoded signal and determining a signal strength of the transmitted digitally encoded signal; and
deterrent means, in response to the specified digital code and the strength level, for producing a deterrent signal which is applied to an animal.

Abstract
An animal confinement arrangement including a home base for transmitting a modulated signal and a receiver for receiving the modulated signal. The received modulated signal is demodulated using a demodulator. The demodulated signal is compared to a reference signal to produce a comparator signal indicating if the received modulated signal was transmitted by the home base. Also provided is variable sensitivity deterrent circuitry which is responsive to a strength level of the received modulated signal and to the comparator signal for producing a variable deterrent signal which is applied to an animal if the comparator signal indicates that the received modulated signal was transmitted by the home base. Communication circuitry and an antenna design allow the user to communicate with the animal. A low battery strength indicator for the battery in the receiver is also provided.
