Interactive sports timer with audio output |
摘要 |
A sports annunciation system is remotely controlled by players in unofficiated games. Players start and stop game timers by wireless communication to a base unit using a switching device on their person. The system audibly announces time-in, time-out, remaining time and key game events. The device simulates time control and announcements found in officiated games.
