1. A confinement arrangement for one of an animal and human comprising:
- home base transmitting means for transmitting a spread spectrum modulated signal from a first signal-emitting wire; and
receiver means for receiving the spread spectrum modulated signal, the receiving means having;
(a) despread demodulation means for despread demodulating the received spread spectrum modulated signal to produce a despread demodulated signal,(b) comparator means for determining whether the received spread spectrum modulated signal was transmitted from the home base transmitting means, and(c) deterrent means, responsive to a signal strength of the received spread spectrum modulated signal, for producing a deterrent signal if the comparator means determined that the received spread spectrum modulated signal was transmitted from the home base transmitting means.

Abstract
A confinement system for animals operates by transmitting a first predetermined spread spectrum modulated signal to a receiver mounted on an animal'"'"'s collar. The spread spectrum modulated signal is despread demodulated. The data on the signal is removed and deciphered by the receiver to determine if the received signal is the correct discrete spread spectrum modulated signal. If the demodulated and reference signals are similar, then the signal strength of the first signal is used to determine whether the animal is close to a boundary area. If the spread spectrum modulated and reference signals are not similar, the first signal is ignored.

26. An animal confinement arrangement comprising:
-
a) a first signal-emitting wire disposed around and defining confinement area; b) a second signal-emitting wire disposed within the confinement area defined by said first signal-emitting wire; c) said home base transmitting means for transmitting a first spread spectrum modulated signal from the first signal emitting wire and a second spread spectrum modulated signal different from the first spread spectrum modulated signal from the second signal emitting wire, the home base transmitting means having an alarm which is activated by an alarm activation signal; and d) a receiver responsive to the first spread spectrum modulated signal and the second spread spectrum modulated signal, the receiver including; (i) deterrent means responsive to a first strength level of the first spread spectrum modulated signal emitted from the first signal-emitting wire producing as an output a deterrent signal, (ii) disconnect and alarm means responsive to a second strength level of the first spread spectrum modulated signal emitted from the first signal-emitting wire, the second strength level being higher than the first strength level, the disconnect and alarm means producing as an output a signal to disconnect said deterrent means and to produce and broadcast to the first signal-emitting wire the alarm activation signal, (iii) reconnect means responsive to the second spread spectrum modulated signal producing as an output a signal to reconnect the disconnected deterrent means, and (iv) an antenna receiving and transmitting a plurality of signals. - View Dependent Claims (27, 28, 29, 30, 31)
