Programmable universal locating system

1. A locating system comprising:

a control unit configured with a program mode and a locate mode, the control unit comprising:

a first integrated circuit;

a transceiver coupled to the first integrated circuit; and

a first actuator coupled to the integrated circuit and configured such that when the control unit is in program mode and the first actuator is activated, the control unit transmits a first signal indicating that the control unit is in program mode and identifying the first actuator.

2. The control unit of claim 1 wherein the identification of the first actuator is a serial bit stream identification.

3. The control unit of claim 1 wherein the identification of the first actuator is a range in a transmission medium.

4. The system of claim 1 further comprising:

a first remote unit configured to have a program mode and a locate mode, wherein the first remote unit upon receiving the first signal enters program mode and stores the identity of the first actuator.

5. The control unit of claim 1 further comprising:

a second actuator coupled to the first integrated circuit and configured such that when the control unit is in program mode and the second actuator is activated, the control unit transmits a second signal indicating that the control unit is in program mode and identifying the second actuator, and the identification for the second actuator differing from the identification for the first actuator.

6. The control unit of claim 5 wherein the control unit is configured such that when in locate mode and responding to activation of the first actuator, the control unit transmits a third signal indicating that the control unit is in locate mode and identifying the first actuator.

7. The control unit of claim 6 wherein the control unit is configured such that when in locate mode and responding to activation of the second actuator, the control unit transmits a fourth signal indicating that the control unit is in locate mode and identifying the second actuator.

8. The control unit of claim 7 further comprising:

a front panel indicator coupled to the first integrated circuit, wherein the control unit is configured to receive a fifth signal in response to the third signal and display upon the front panel indicator the relative distance of the source of the fifth signal based on the strength of the fifth signal.

9. The control unit of claim 8 wherein the control unit is configured to receive a sixth signal in response to the fourth signal and display upon the front panel indicator the relative distance of the source of the sixth signal based on the strength of the sixth signal, the sixth signal having a different source than the fifth signal.

10. The system of claim 5 further comprising:

a first remote unit configured to have a program mode and a locate mode, wherein the first remote unit upon receiving the first signal enters program mode and stores the identity of the first actuator; and

a second remote unit configured to have a program mode and a locate mode, wherein the second remote unit upon receiving the second signal enters program mode and stores the identity of the second actuator.

11. The system of claim 10 wherein, during transmission of the first signal, the first remote unit is in close proximity to the control unit and the second remote unit is not in close proximity to the control unit, and during transmission of the second signal, the first remote unit is not in close proximity to the control unit and the second remote unit is in close proximity to the control unit.

12. A remote unit comprising:

a transceiver; and

an integrated circuit coupled to the transceiver, wherein the remote unit is configured to receive a first signal from a control unit locating device, the first signal indicating a program mode and identifying a first actuator, the integrated circuit storing the identity of the first actuator.

13. The remote unit of claim 12 wherein the remote unit is configured to receive a second signal from the control unit locating device, the second signal indicating a program mode and identifying a second actuator, the integrated circuit storing the identity of the second actuator.

14. The remote unit of claim 13 wherein the stored identity of the second actuator replaces the stored identity of the first actuator.

15. The remote unit of claim 13 wherein the integrated circuit stores the identity of the second actuator in addition to the stored identity of the first actuator.

16. The remote unit of claim 12 wherein the remote unit is configured to receive a second signal from the control unit locating device, the second signal indicating a locate mode and identifying a first actuator, the remote unit responding by transmitting a third signal if the identity of the first actuator was received by the remote unit during a program mode and the identity of the first actuator is stored in the remote unit.

17. The remote unit of claim 16 wherein the third signal is an audible signal.

18. The remote unit of claim 12 further comprising a serial bit stream identification in the identification of the first actuator.

19. The remote unit of claim 12 further comprising a range in the transmission medium in the identification of the first actuator.

20. The remote unit of claim 12 further configured to emit an audible signal upon storage of the identity of the first actuator.

21. A locating system comprising:

a control unit configured with a program mode and a locate mode, the control unit comprising:

a transceiver;

a first actuator coupled to the transceiver; and

a means for transmitting a signal in the program mode, the signal containing an identity for the actuator and intended to identify the actuator for use in the locate mode.

22. A remote unit comprising:

a transceiver;

a means for receiving a program signal from a control unit locating device, the program signal containing an identity for an actuator; and

a means for storing the identity of the actuator for comparison with a locate signal.
