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.

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.

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. - View Dependent Claims (16, 17, 18, 19, 20)
