  • Publication number: 20120256373
    Abstract: A portable scoreboard system comprising of a microcontroller running a software algorithm that keeps score of a sports game and officiates the game to ensure fair play according to the rules of the sport. The official rules of all the sports are stored in the device memory. The updating of the score is carried out with wireless remote control modules worn by the players and/or users. The score is only updated when the algorithm has confirmed no game rule violations. The real time score information is then displayed on the scoreboard panel plus appropriate audio sounds are played. Game related scores and user settings are stored into memory on a real time basis and can be retrieved externally for post-game analysis.
