Abstract

A pet restraint system includes a collar having first and second ends and a fastener to selectively secure the first and second collar ends about a pet. A radio transmitter is coupled to the collar that emits a signal at a predetermined frequency. The system includes a handheld unit separated from the collar that includes a radio receiver configured to receive a radio signal, a GPS receiver for receiving signals from global positioning satellites, a signal indicator, and a CPU in data communication with the radio receiver, GPS receiver, and signal indicator. The CPU includes programming for evaluating a relative strength of signals received by the radio receiver and for outputting the relative strength to the signal indicator indicative of a position of the signal transmitter relative to the handheld unit. The CPU also includes programming for evaluating GPS signals and determining a global position of the handheld unit.

Claims

2. The restraint system as in claim 1, further comprising:

a GPS receiver positioned in said handheld unit;

wherein said CPU includes programming for evaluating said GPS signals received by said GPS receiver and calculating global position data from said GPS signals; and

said CPU includes programming for outputting said global data to said signal indictor indicative of a position of said handheld unit.

3. The pet restraint system as in claim 2, wherein said signal indicator is an audible device.

4. The pet restraint system as in claim 2, wherein said signal indicator is a visual display.

5. The pet restraint system as in claim 1, further comprising a solar cell coupled to said collar and electrically connected to said radio transmitter.

6. The pet restraint system as in claim 1, wherein said handheld unit includes a battery electrically connected to said CPU.

7. The pet restraint system as in claim 1, wherein:

said fastener includes;

a pin configured to respectively interact with said holes to secure said adjustable collar circumference in a plurality of respective positions;

a clasp configured to secure said pin when at a first position and release said pin when at a second position; and

an outer casing movable between a closed configuration enclosing said clasp and an open configuration exposing said clasp;

a lock configured to restrict separation of said first and second collar ends, said lock being operatively coupled to said outer casing to restrict movement of said outer casing from said closed configuration to said open configuration;

said clasp is movable to said second position only when said outer casing is at said open configuration;

8. The restraint system as in claim 7, further comprising:

a GPS receiver positioned in said handheld unit;

wherein said CPU includes programming for evaluating said GPS signals received by said GPS receiver and calculating global position data from said GPS signals; and

said CPU includes programming for outputting said global data to said signal indictor indicative of a position of said handheld unit.

9. The pet restraint system as in claim 8, wherein said signal indicator is an audible device.

10. The pet restraint system as in claim 8, wherein said signal indicator is a visual display.

11. The pet restraint system as in claim 7, further comprising a solar cell coupled to said collar and electrically connected to said radio transmitter.

12. The pet restraint system as in claim 11, wherein said handheld unit includes a battery electrically connected to said CPU.

13. A pet restraint system, comprising:
