Abstract

Improved systems and methods for timing athletic events. A radio-based starter unit and a radio based timer unit communicate wirelessly via radio. Push buttons/switches and lights and a speaker in the units provide an intuitive, easy to use interface. Handshaking occurs between the starter unit and the timer unit, and lights indicate that the event is ready to start. Real time clocks in the units are synchronized. Upon detection of race or other event start, such as from a starter'"'"'s pistol, information indicative of the race start time is transmitted from the start unit to the timer unit. A camera in communication with the timer unit provides video frames, and the timer unit encodes and inserts elapsed time information in the video frames, which are then output from the timer unit for review and analysis on a computer.

Claims

1. A system for timing an athletic event, comprising:

a starter unit including a radio unit, a user-operable switch interface, a user-visible output interface and processing circuitry providing a real time clock;

a timer unit including a radio unit, a user-operable switch interface, a user-visible output interface and processing circuitry providing a real time clock;

a camera coupled to the timer unit and providing video information to an input of the timer unit;

wherein an operator of the starter unit exchanges commands with an operator of the timer unit via the user-operable switch interface, wherein the starter unit and the timer unit exchange information to synchronize their respective real time clocks, wherein an indication is provided by the user-visible output interface that the event is ready to be started, wherein processing circuitry of the starter unit detects the start of the event and subsequently sends information indicative of a race start time to the timer unit, wherein the timer unit outputs video frames that encode information indicative of an elapsed race time in the output video frames.
