Confinement arrangement for animals

Claim 2

An animal confinement arrangement comprising: a) a home base transmitting means for transmitting a first, unmodulated, signal (A), and a second, modulated, signal (B); b) a first signal-emitting wire responsive to said first, unmodulated signal, said first signal-emitting wire disposed around a confinement area; c) a second signal-emitting wire responsive to said second, modulated, signal, said second signal-emitting wire disposed adjacent said home base, within the confinement area defined by said first signal-emitting wire; d) a receiver capable of being attached to an animal and responsive to said first and said second signals, said receiver including: (i) a deterrent circuit responsive to a first strength level of said first, unmodulated, signal emitted from said first signal-emitting wire, for producing as an output a deterrent signal which is applied to the animal; (ii) a disconnect and alarm circuit responsive to a second strength level of said first, unmodulated, signal emitted from said first signal-emitting wire, said second strength level being higher that said first strength level, said circuit producing as an output a signal to disconnect said deterrent circuit and to produce and broadcast to said first signal-emitting wire an alarm activation signal; and (iii) a reconnect circuit responsive to said second, modulated, signal for producing as an output a signal to reconnect said disconnected deterrent circuit; and e) an alarm circuit responsive to said alarm activation signal.

Claim 3

The confinement arrangeement of claim 1 wherein said receiver deterrent circuit produces an electrical shock as an output deterrent signal.

Claim 4

The confinement arrangement of claim 1 wherein said receiver deterrent circuit produces as an output deterrent signal an audio signal at a predetermined frequency which is unpleasant to the animal.

Claim 5

The confinement arrangement of claim 1 wherein said receiver deterrent circuit produces as an output deterrent signal both an electrical shock and an audio signal at a predetermined frequency which is unpleasant to at least one animal.

Claim 6

The confinement arrangement of claim 1 in which said transmitting means comprises: a) oscillator means for generating an oscillating signal of predetermined frequency, and for outputting said signal as a first and second oscillator output; b) first transmitter means coupled to said first oscillator output for transmitting said first oscillator output to said first signal-emitting wire; c) modulator means coupled to said second oscillator output for modulating said second oscillator output; and d) second transmitter means coupled to said modulator for transmitting said modulator output to said second signal-emitting wire.

Claim 7

The confinement arrangement of claim 1 in which said alarm circuit comprises: a) an antenna for receiving said alarm activation signal broadcast by said first signal-emitting wire; b) filtering means responsive to the received signal for eliminating frequencies below a first predetermined frequency and above a second predetermined frequency; c) amplifying means coupled to the output of said filtering means for increasing the signal level of the filtered received signal; and d) detecting means coupled to the output of said amplifying means for detecting the presence of said alarm signal and generating as an output a control signal when said alarm signal is present.

Claim 8

The confinement arrangement of claim 6 in which said deterrent, disconnect and alarm circuits comprise: a) an antenna for receiving said first, unmodulated, signal emitted by said first signal-emitting wire; b) filtering means responsive to the received signal for eliminating frequencies below a first predetermined frequency and above a second predetermined frequency; c) amplifying means coupled to the output of said filtering means for increasing the signal level of the filtered received signal; d) first detecting means coupled to the output of said amplifying means responsive to said first strength level of said first unmodulated signal emitted from said first signal-emitting wire, for generating as an output a first detector signal; e) second detecting means coupled to the output of said amplifying means responsive to said second strength level of said first, unmodulated, signal emitted from said first signal-emitting wire, for generating as an output a second detector signal; f) first relay means coupled to said first and second detector signal for producing as an output a first relay control signal; g) second relay means coupled to said first relay control signal for activating and deactivating a deterrent device; h) third relay means coupled to said second detector signal for producing as an output a third relay signal; i) oscillator means coupled to said output of said third relay for generating as an output an oscillating signal of predetermined frequency; j) transmitter means coupled to said oscillator output for transmitting said oscillator output to said alarm circuit.

Claim 9

The invention of claim 7 in which said reconnect circuit comprises: a) a third detecting means coupled to the output of said amplifying means responsive to said second, modulated, signal emitted from said second signal-emitting wire, for generating as an output a second detector signal; and b) fourth relay means coupled to said third detector signal for activating and deactivating said first relay means.

Claim 10

The invention of claim 8 in which said predetermined frequency of said first, unmodulated, signal A and said second, modulated, signal B is 30 KHz.

Claim 11

The invention of claim 9 in which the first strength level is between 0.001 and 0.005 Watts.

Claim 12

The invention of claim 10 in which the second strength level is between 0.01 and 0.05 Watts.

Claim 13
