1. An animal confinement arrangement comprising:
- a first signal-emitting wire disposed around a confinement area;
a second signal-emitting wire;
home base transmitting means for transmitting a first modulated signal from the first signal-emitting wire and a second modulated signal from the second signal-emitting wire, the first modulated signal having a first signal strength;
receiver means for receiving any of a plurality of modulated signals including the first modulated signal, as a received modulated signal;
demodulator means for demodulating the received modulated signal to produce a demodulated signal having a second signal strength;
comparator means for comparing the demodulated signal to a reference signal to determine if the received modulated signal was transmitted by the home base transmitting means; and
deterrent means, responsive to the second signal strength of the demodulated signal, for producing a deterrent signal which is applied to the animal if the comparator means determines that the received modulated signal was transmitted by the home base transmitting means.

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 deterrent circuitry which is responsive to a strength level of the received modulated signal and to the comparator signal for producing a deterrent signal which is applied to an animal if the comparator signal indicates that the received modulated signal was transmitted by the home base.

5. An animal confinement arrangement comprising:
-
a) a first signal-emitting wire disposed around a confinement area; b) a second signal-emitting wire disposed within the confinement area defined by said first signal-emitting wire; c) a home base transmitting means for transmitting a first modulated signal from the first signal-emitting wire and a second modulated signal from the second signal emitting wire, wherein the second modulated signal is different from said first modulated signal; and d) a receiver responsive to said first modulated signal and said second modulated signal, said receiver including; (i) deterrent means responsive to a first strength level of said first modulated signal emitted from said first signal-emitting wire for producing as an output a deterrent signal which is applied to an animal, (ii) disconnect means responsive to a second strength level of said first modulated signal emitted from said first signal-emitting wire, said second strength level being higher than said first strength level, said disconnect means producing as an output a signal to disconnect said deterrent means, and (iii) reconnect means responsive to said second modulated signal for producing as an output a signal to reconnect said disconnected deterrent means. - View Dependent Claims (6, 7, 8, 9, 10, 11)
