Abstract

An improved wireless timing system shown in FIG. 1 comprising a means of transmitting wirelessly a signal (12) triggered by the reception of an electrical impulse from a timing event detector (11). The transmitter (12) being low power and thus short range to reduce cost, power consumption and interference with other timing systems. The individual or object being timed transports a portable timing unit (16), which could be in the form of a wrist watch, that is capable of receiving the wireless timing signal and calculating the passage of time between successive receptions of timing signals.

Claims

1. A wireless timing system comprising:

a means of transmitting wirelessly a signal that precisely indicates when an external timing event occurs

said means of transmitting wirelessly a signal not having sufficient range to entirely cover the event being timed

a portable means of determining elapsed time transported by the individual or object being timed

a means of controlling said portable means of determining elapsed time by said signal

whereby an external event that starts in one location and finishes in another location can be timed without the need of a direct communication link between the starting event location and the finishing event location.

2. The wireless timing system in claim one wherein said portable means of determining elapsed time is in the form of a wrist watch.

3. The wireless timing system in claim one further including a means of detecting duplicate timing signals.

4. The wireless timing system in claim one further including a means calculating speed.

5. The wireless timing system in claim one further including a means of encrypting the wireless timing signal.

6. The wireless timing system in claim one further including a means of coding an address in the timing signal.

7. The wireless timing system in claim one further including a means of detecting if said timing signal is corrupted.

8. A wireless timing system comprising:

a means of transmitting wirelessly a signal that precisely indicates when an external timing event occurs

said means of transmitting wirelessly a signal not having sufficient range to entirely cover the event being timed

a portable means of determining elapsed time transported by the individual or object being timed

a means of controlling said portable means of determining elapsed time by said signal

and a means of correcting said timing signal to reflect the true time of the event based on delay information passed by said timing signal

whereby an external event that starts in one location and finishes in another location can be timed without the need of a direct communication link between the starting event location and the finishing event location.

9. The wireless timing system in claim 8 wherein said portable means of determining elapsed time is in the form of a wrist watch.

10. The wireless timing system in claim 8 further including a means of detecting duplicate timing signals.

11. The wireless timing system in claim 8 further including a means of encrypting the wireless timing signal.

12. The wireless timing system in claim 8 further including a means of coding an address in the timing signal.

13. The wireless timing system in claim 8 further including a means calculating speed.

14. The wireless timing system in claim 8 further including a means of detecting if said timing signal is corrupted.

15. A method for timing an event that starts in one location and finishes in another location comprising the steps of:

providing a means of transmitting wirelessly a signal that precisely indicates when an external timing event occurs

said wireless signal not having sufficient range to entirely cover the event being timed

providing a portable means of determining elapsed time transported by the individual or object being timed

providing a means of controlling said portable means of determining elapsed time by said signal

whereby an external event that starts in one location and finishes in another location can be timed without the need of a direct communication link between the starting event location and the finishing event location.

16. The method of claim 15 wherein said portable means of determining elapsed time is in the form of a wrist watch.

17. The method of claim 15 further including a means of detecting duplicate timing signals.

18. The method of claim 15 further including a means of encrypting the wireless timing signal.

19. The method of claim 15 further including a means of coding an address in the timing signal.

20. The method of claim 15 further including a means calculating speed.
