Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
115 words
An electronic scoring system for keeping score between two opposing sides each including one or more opponents, comprising: a first electronic transmitting device to be selectively actuated by one side to indicate which side won each successive point; a second electronic transmitting device to be selectively actuated by the other side to indicate which side won each successive point; receiving and scoring means for initially storing a preliminary indication as to who won each successive point; additional logic circuit means for preventing the full recording of the preliminary indication if it is disputed by the other side; and means for fully recording the point if it is not disputed, and for displaying the resultant score.
Claim 2
Dependent Claim
115 words
An electronic scoring system for keeping score between two opposing sides each including one or more opponents, comprising: a first electronic transmitting device to be selectively actuated by one side to indicate which side won each successive point; a second electronic transmitting device to be selectively actuated by the other side to indicate which side won each successive point; receiving and scoring means for initially storing a preliminary indication as to who won each successive point; additional logic circuit means for preventing the full recording of the preliminary indication if it is disputed by the other side; and means for fully recording the point if it is not disputed, and for displaying the resultant score.
Claim 3
Dependent Claim
33 words
An electronic scoring system as defined in claim 1 wherein each said transmitting device includes two switch means for selective actuation to indicate that one party or the other won each successive point.
Claim 4
Dependent Claim
63 words
An electronic scoring system as set forth in claim 2 wherein both of said transmitters include means for transmitting different signals to indicate alternatively whether one side or the other has won a point; and means are provided for only recording a point for one side or the other when both transmitters send signals confirming that one particular side has won the point.
Claim 5
Dependent Claim
37 words
An electronic scoring system as defined in claim 1 wherein means are provided for securing said first transmitting device to a player on one side and said second transmitting device to a player on the other side.
Claim 6
Dependent Claim
31 words
An electronic scoring system as defined in claim 1 wherein said receiving and scoring logic circuitry is mounted in a separate unit which displays the score for viewing by both sides.
Claim 7
Dependent Claim
26 words
An electronic scoring system for tennis as defined in claim 5 further comprising: means for securing said separate logic and display unit to a tennis fence.
Claim 8
Dependent Claim
25 words
An electronic scoring system as defined in claim 1 further comprising: means for providing distinctly different audio signals indicating score changes for the different sides.
Claim 9
Dependent Claim
23 words
An electronic scoring system for tennis as defined in claim 7 wherein a separate deuce signal and two separate advantage signals are provided.
Claim 10
Dependent Claim
40 words
An electronic scoring system for tennis as defined in claim 1 further comprising: means for displaying the tennis point score, including means for indicating deuce and advantage scores; means for displaying the game score; and means for displaying set score.
Claim 11
Dependent Claim
23 words
An electronic scoring system as defined in claim 1 further comprising: means including a plurality of multi-segment electronic displays for indicating the score.
Claim 12
Dependent Claim
68 words
A tennis electronic scoring system as defined in claim 1 including: tennis point counter means for each side; game counter means for each side; set counter means for each side; and means for clearing both of said point counter means when either of said game counter means is advanced; and means for clearing both of said game counter means when either of said set counter means is advanced.
Claim 13
Dependent Claim
31 words
A system as defined in claim 1 further comprising: means for protecting said transmitting devices against inadvertent actuation, whereby a game ball or accidental bodily movement will not actuate said switches.
Claim 14
Dependent Claim
98 words
An electronic scoring system for keeping score between two opposing sides each including one or more opponents, comprising: first and second electronic transmitting devices each including at least one input switch to be selectively actuated in favor of one side or the other to indicate which side won each successive point; means for securing said first transmitting device to a player on one side and said second transmitting device to a player on the other side; and receiving and scoring logic circuitry for recording inputs from said first and said second transmitters and for displaying the resultant score.
Claim 15
Dependent Claim
98 words
An electronic scoring system for keeping score between two opposing sides each including one or more opponents, comprising: first and second electronic transmitting devices each including at least one input switch to be selectively actuated in favor of one side or the other to indicate which side won each successive point; means for securing said first transmitting device to a player on one side and said second transmitting device to a player on the other side; and receiving and scoring logic circuitry for recording inputs from said first and said second transmitters and for displaying the resultant score.
Claim 16
Dependent Claim
32 words
A system as defined in claim 11 further comprising: means for protecting said switches against inadvertent actuation, whereby a game ball or accidental bodily movement will not actuate one of said switches.
