Table tennis wireless scoring system

Abstract

A wireless scoring system for a game, such as table tennis. The scoring system is mounted to or adjacent the table tennis table. The scoring system includes a casing with a first display showing the first team's score and a second display showing the second team's score. The first and second displays are connected to a controller and a signal receiver configured to receive a first scoring signal and a second scoring signal. Each team is provided with a transmitter for sending a first signal or second signal. Upon activation, the transmitter sends a signal to the scoring signal receiver and controller to add one point to the corresponding score. After each five serves, the scoring system produces a signal to indicate a change of service. When one team reaches twenty-one or higher with a lead of two, the scoring system generates a game over signal.

         5 . The scoring system of  claim 1  wherein said scoring signal receiver is a radio frequency receiver configured to receive said first scoring signal on a first radio frequency and said second scoring signal on a second radio frequency.  
     
     
         6 . The scoring system of  claim 5  wherein said first scoring signal transmitter comprises a radio frequency transmitter configured to transmit on said first radio frequency and a signal activator to activate said radio frequency transmitter.  
     
     
         7 . The scoring system of  claim 6  wherein said signal activator is a push button.  
     
     
         8 . The scoring system of  claim 6  further comprising a change of serve indicator coupled to said controller, wherein said controller defines a score tally variable, initially equal to zero, which is raised by one each time said controller receives a first scoring signal or a second scoring signal, and wherein said change of serve indicator is activated and said score tally is reset to zero each time said score tally equals five.  
     
     
         9 . The scoring system of  claim 8  wherein said change of serve indicator comprises a speaker or buzzer.  
     
     
         10 . The scoring system of  claim 8  further comprising an end of game indicator coupled to said controller wherein said end of game indicator is activated upon the first of said first score or second score totaling 21 or greater with the difference between said first score and said second score equal to 2 or greater.  
     
     
         11 . The scoring system of  claim 10  wherein said end of game indicator comprises a speaker or buzzer.  
     
     
         12 . The scoring system of  claim 1  wherein said first score display and said second score display are digital.  
     
     
         13 . A wireless scoring system for a game, comprising: 
 a) a first score display displaying a first score;    b) a second score display displaying a second score;    c) a first scoring signal transmitter selectively operable to transmit a first scoring signal;    d) a second scoring signal transmitter selectively operable to transmit a second scoring signal;    e) a scoring signal receiver wherein said scoring receiver is configured to receive at least a first scoring signal and a second scoring signal; and,    f) a controller coupled to said scoring signal receiver, said first score display and said second score display, wherein said scoring signal receiver communicates each received scoring signal to said controller, and wherein said controller raises the score on said first score display upon receiving said first scoring signal and wherein said controller raises the score displayed on said second score display upon receiving said second score signal.    
     
     
         14 . The scoring system of  claim 13  wherein said scoring signal receiver is a radio frequency receiver configured to receive said first scoring signal on a first radio frequency and said second scoring signal on a second radio frequency.  
     
     
         15 . The scoring system of  claim 14  wherein said first scoring signal transmitter comprises a radio frequency transmitter configured to transmit on said first radio frequency, and a signal activator to activate said radio frequency transmitter.  
     
     
         16 . The scoring system of  claim 13  further comprising a change of serve indicator coupled to said controller.  
     
     
         17 . The scoring system of  claim 13  further comprising an end of game indicator coupled to said controller.  
     
     
         18 . A table tennis game system including a wireless scoring system, comprising: 
 a) a table tennis table;    b) a first score display displaying a first score mounted adjacent said table tennis table;    c) a second score display displaying a second score mounted adjacent said table tennis table;    d) a controller mounted adjacent said table tennis table and operably connected to said first score display and said second score display;    e) a first scoring radio signal transmitter selectively operable to transmit a first scoring radio signal; and,    f) a second scoring radio signal transmitter selectively operable to transmit a second scoring radio signal; and,    g) a radio receiver coupled to said controller, wherein said radio receiver is configured to receive said first scoring radio signal and said second scoring radio signal and communicate each signal to said controller, and wherein said controller raises the score on said first score display upon receiving said first scoring signal and wherein said controller raises the score displayed on said second score display upon receiving said second score signal.
