Abstract

A method of providing wireless animal confinement includes the steps of selecting a location of a transmitter assembly; attaching a receiver assembly to the animal, the receiver assembly being adapted to selectively provide a corrective stimulation to the animal; selecting a first distance between the transmitter assembly and the receiver assembly to define a first zone within which no corrective stimulation is provided to the animal by the receiver assembly; selecting a second distance between the transmitter assembly and the receiver assembly to define a second zone beyond the first zone within which the corrective stimulation is provided to the animal by the receiver assembly; and selecting a third distance between the transmitter assembly and the receiver assembly to define a third zone beyond the second zone within which the animal will receive no further corrective stimulation from the receiver assembly.

Claims

1. A method of providing wireless confinement of an animal, comprising the steps of:

selecting a location of a containment transmitter assembly;

attaching a receiver assembly to said animal, said receiver assembly being adapted to selectively provide a corrective stimulation to said animal;

selecting a first distance between said containment transmitter assembly and said receiver assembly to define a first zone within which no corrective stimulation is provided to said animal by said receiver assembly;

selecting a second distance between said containment transmitter assembly and said receiver assembly to define a second zone beyond said first zone within which said corrective stimulation is provided to said animal by said receiver assembly;

selecting a third distance between said containment transmitter assembly and said receiver assembly to define a third zone beyond said second zone within which said animal will receive no further corrective stimulation from said receiver assembly; and

providing a training transmitter, separate from said containment transmitter assembly, for controlling said receiver assembly to selectively apply corrective stimulation to said animal regardless of a location of said receiver assembly with respect to said first zone, said second zone and said third zone.

2. The method of claim 1, wherein said corrective stimulation comprises at least one of an audio stimulation and a tactile stimulation.

3. The method of claim 2, wherein said tactile stimulation is at least one of an electrical shock and an emission of a scent.

4. The method of claim 1, further comprising the step of defining a fourth zone located between said second zone and said third zone within which a high level corrective stimulation is provided to said animal by said receiver assembly.

5. The method of claim 1, wherein if at least one of said containment transmitter assembly and said receiver assembly suffers a hardware failure, said animal will not receive said corrective stimulation.

6. The method of claim 1, wherein once said animal enters said third zone, said receiver assembly is disabled from providing further corrective stimulation.

7. The method of claim 1, wherein said containment transmitter assembly transmits a ranging signal.

8. The method of claim 7, further comprising the step of said receiver assembly receiving said ranging signal and comparing a signal strength of said ranging signal to a first threshold associated with said first distance.

9. The method of claim 8, further comprising the step of defining a second threshold associated with said second distance and a third threshold associated with said third distance based on a predefined signal strength reduction from said first threshold.

10. The method of claim 8, further comprising the step of determining said signal strength based on at least one of a signal amplitude and a signal-to-noise ratio of said ranging signal.

11. The method of claim 8, further comprising the step of said containment transmitter assembly transmitting a synchronization signal that said receiver assembly receives and uses to synchronize said ranging signal.

12. The method of claim 1, wherein said containment transmitter assembly is portable.

13. The method of claim 1, wherein said containment transmitter assembly is weatherproof.

14. The method of claim 1, wherein said containment transmitter assembly is solar powered.

15. A system for providing wireless confinement of an animal, comprising:

a containment transmitter assembly which transmits a ranging signal having a signal strength which diminishes over a propagation distance;

a receiver unit for receiving said ranging signal, said receiver unit having stored therein a first signal strength threshold corresponding a first distance between said containment transmitter assembly and said receiver unit, a second signal strength threshold corresponding to a second distance between said containment transmitter assembly and said receiver unit;

a correction unit controllably connected to said receiver unit, said correction unit providing no corrective stimulation to said animal based on if said receiver unit determines said signal strength of said ranging signal is more than said first signal strength threshold, said correction unit providing corrective stimulation to said animal if said receiver unit determines said signal strength of said ranging signal is between said first signal strength threshold and said second signal strength threshold, and said correction unit providing no further corrective stimulation to said animal if said receiver unit determines said signal strength of said ranging signal is less than said third signal strength threshold; and

a training transmitter, separate from said containment transmitter assembly, for selectively supplying a signal to said receiver to command said correction unit to apply corrective stimulation to said animal regardless of a location of said animal.

16. The system of claim 15, wherein said corrective stimulation comprises at least one of an audio stimulation and a tactile stimulation.

17. The system of claim 16, wherein said tactile stimulation is at least one of an electrical shock and a scent.

18. The system of claim 15, wherein said receiver unit has stored therein a third signal strength threshold corresponding to a third distance between said containment transmitter assembly and said receiver assembly, said correction unit provides a high level corrective stimulation to said animal if said receiver unit determines said signal strength of said ranging signal is between said second signal strength threshold and said third signal strength threshold.

19. The system of claim 15, wherein if at least one of said containment transmitter assembly and said receiver unit suffers a hardware failure, said animal will not receive said corrective stimulation.

20. The system of claim 15, wherein if said receiver unit determines said signal strength of said ranging signal is less than said third signal strength threshold, said correction unit is disabled from providing further corrective stimulation.
