ABSTRACT:
The present tennis scoring system includes input devices for each player to indicate whether one player or the other has won a particular point. These input devices for each player may be in the form of transmitters each having two recessed pushbutton switches, one to indicate that one player has won the point and the other to indicate that the opposing player has won the particular point.
The input device may take the form of a belt buckle size unit worn at the waist or on the wrist. Electronic scoring circuitry is provided which is responsive to the concurrent depressing of buttons by both players indicating who has won a particular point. Electronic scoring equipment keeps track of the points, games, sets and matches won by each player and each side. Suitable electronic equipment is provided to accommodate slight differences in the timing of the pressing of input switches by the two players. Special logic circuitry is provided for accommodating the tennis scoring situation involving deuce games. Transmitters with unique signals to indicate who has won a point are provided. A common display and annunciator unit may be used which receives signals from input devices of each player. Alternatively, small LED displays may be provided on each of the input units to display the points, games, sets and matches won by each player and each team. The annunciator may provide a unique sound to indicate points won by one player as compared with a different sound for points won by the other player.
