Definitions
- Knowing the speed of the service ball is important for the player and the spectator. Sophisticated radar installations are not within the reach of the vast majority of courts and amateurs too would like to know their performance. Here is a classic wristwatch with an immediate digital reading of the speed. The watch is completely independent of the system which calculates and displays the speed and is the practical support.
- Each press on the pusher (1) alternately switches the calculation mode to kilometers or miles (2).
- the distance traveled by the ball is chosen at 18m, 50 (3) by the lateral pressure pusher (4) which scrolls the distances in one direction or the other.
- the pusher (b) for the first time when the racket hits the ball and a second time when it hits the serve square.
- the watch comprising a microprocessor system and computer software becomes aware of this time interval and after a rule of three instantly displays the speed in kilometers (6). Converting to miles requires an additional division by 1.609 with results rounded to the nearest kilometer or mile.
- This watch can be used in other games and sports with distances up to 100 meters and times up to the minute, in athletics, golf biking etc.
- the display of the results during a competition is done within a few seconds by manual or electronic display with remote control.
