Abstract
Abstract An animal confinement system is disclosed where a boundary is defined by converting energy radiated from a point source into a curtain. A code is transmitted within this curtain so that a receiver carried by an animal can receive the code and issue a suitable instruction to the animal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
96 words
An animal confining system comprising means for establishing a boundary including a point source of radiated energy, means for converting said radiated energy into a curtain of radiated energy, means for transmitting an encoded signal within said curtain of radiated energy, and a collar to be worn by an animal to be confined including means for issuing an instructional command, means for receiving said radiated energy when the animal is within said curtain of radiated energy, and means for decoding said encoded signal and operating said instructional command issuing means upon receipt of said decoded signal.
Claim 2
Dependent Claim
96 words
An animal confining system comprising means for establishing a boundary including a point source of radiated energy, means for converting said radiated energy into a curtain of radiated energy, means for transmitting an encoded signal within said curtain of radiated energy, and a collar to be worn by an animal to be confined including means for issuing an instructional command, means for receiving said radiated energy when the animal is within said curtain of radiated energy, and means for decoding said encoded signal and operating said instructional command issuing means upon receipt of said decoded signal.
Claim 3
Dependent Claim
34 words
An animal confining system according to claim 1, wherein instructional command issuing means comprises means for altering the instructional command as a function of proximity to the centerplane of said curtain of radiated energy.
Claim 4
Dependent Claim
28 words
An animal confining system according to claim 1, wherein said means for converting said radiated encoded energy into a curtain of encoded radiated energy establishes a linear curtain.
Claim 5
Dependent Claim
23 words
An animal confining system according to claim 1, further comprising means for supporting said point source of encoded radiated energy above the ground.
Claim 6
Dependent Claim
63 words
An animal confining system according to claim 1, wherein said boundary establishing means comprises a plurality of spaced point sources and a corresponding number of means for converting the encoded energy radiated from an associated point source into a curtain of encoded radiated energy, and corresponding number of transmitting means for transmitting said encoded signal within each of said curtains of radiated energy.
Claim 7
Dependent Claim
108 words
An animal confining system, according to claim 1 comprising means for establishing a second boundary adjacent said first boundary including a point source of encoded radiated energy having a second code, and means for converting said radiated encoded energy into a second curtain of encoded radiated energy having a second code; means for issuing a second instructional command, means for receiving said encoded energy having said second code when the animal is within said second curtain and converting said encoded energy signal into an encoded signal having a second code, and means for decoding said encoded signal having said second code and operating said second instructional command means.
Claim 8
Dependent Claim
89 words
An animal confining system comprising means for establishing a boundary including a point source of radiated energy, and optical means for converting said radiated energy into a curtain of radiated energy, and a collar to be worn by an animal to be confined including means for issuing an instructional command, means for receiving said radiated energy when the animal is within said curtain of radiated energy, and converting said received radiated energy into a signal, and means for operating said instructional command issuing means upon receipt of said signal.
Claim 9
Dependent Claim
89 words
An animal confining system comprising means for establishing a boundary including a point source of radiated energy, and optical means for converting said radiated energy into a curtain of radiated energy, and a collar to be worn by an animal to be confined including means for issuing an instructional command, means for receiving said radiated energy when the animal is within said curtain of radiated energy, and converting said received radiated energy into a signal, and means for operating said instructional command issuing means upon receipt of said signal.
Claim 10
Dependent Claim
104 words
An animal confining system, according to claim 7 further comprising means for establishing a second boundary adjacent to said first boundary including a second point source of different radiated energy, and optical means for converting said radiated energy from a second point source into a second curtain of radiated energy, wherein said collar further comprises means for issuing a second instructional command, means for receiving the energy radiated from said second point source when the animal is within said second curtain and converting said energy into a second signal, and means for operating said second instructional command means upon receipt of said second signal.
Claim 11
Dependent Claim
49 words
An animal confining system according to claim 8, wherein said optical means for converting said radiated energy from said first point source into a curtain of radiated energy comprises said optical means for converting said radiated energy from said second point source into said second curtain of radiated energy.
Claim 12
Dependent Claim
38 words
An animal confining system according to claim 8, wherein said second instructional command issuing means comprises means for altering the second instructional command as a function of proximity to the centerplane of said second curtain of radiated energy.
Claim 13
Dependent Claim
35 words
An animal confining system according to claim 7, wherein said instructional command issuing means comprises means for altering the instructional command as a function of proximity to the centerplane of said curtain of radiated energy.
