SUMMARY OF THE PRESENT INVENTION

The present invention discloses a method and apparatus for a watch-like case containing a central processing unit and an input/output controller connected to the central processing unit, a display driver that takes data from the central processing unit and converts it into the electrical signals required by the alphanumeric display, a program read only memory ROM connected to the central processing unit wherein the ROM contains the operating program for the present invention and a clock circuit connected to the CPU. The watch case also comprises an alphanumeric screen which has an luminescent background which displays various tennis related data and is controlled by a plurality of buttons disposed on the watch case.

There are underwater diving watches, skydiving watches, calculator watches, stopwatches, watches that tell basic time like: Eastern, Central, Pacific time zones, and overseas time, but no sports watch that keeps time and scores of a tennis match like the present invention. The scores are displayed digitally and DC cell powered. The scores, games, and aces are activated by pressing the associate letter and/or number for the appropriate functions. The scores, aces, and games can be cleared when an error is made, simply by pressing the corresponding button for two-three seconds. To clear all data, simply press clear once and hold the button down until it clears.

There are very few if any sports timing devices that address the problems of keeping the scores and games stats while a player plays the game of tennis by the use of a wrist watch.

Normally there are no coaches or umpires around to keep the scores. It is left up to the players to keep the scores. In the heat of the battle one or both players often forget the scores and could cause much confusion and arguments on and off the court.

Most clubs, high schools, and colleges have ten to twenty tennis courts which have no scoreboards nor any means of keeping the scores while playing the tennis matches other than the players themselves.

Another advantage of the present invention is that is portable, lightweight, and readily available for quick and easy push button scoring right at your fingertips. In normal match play, twenty-five seconds is the allotted time to prepare to serve for the next point. This is enough time to punch in your scores and stats and make any corrections. The present invention is reasonably priced and inexpensive to manufacture. It can be made of plastic, metal, gold, and/or silver, with a stainless steel backing, and electronic integrated circuitry.

Other advantages of the present invention are that the digital numbers are bigger and magnified for night play, also has an electro illuminasent background with a pushbutton light, so the younger and older players can see the numbers clearly. Also, the buttons are fewer and bigger than calculator watches. Calculator Wristwatch buttons are much smaller in size needing the assistance of a pencil or some form of pointer to press the buttons. Can you imagine the dangers of running around the tennis court with a sharp instrument in your pants pocket or under your skirt. To use the present invention you only need one to two fingers to press the buttons. You don't even have to go to your seat to keep score.

Another advantage is that you can set your present invention alarm in case of a long set or a long tie-break, and let the watch be the judge.

An object of the present invention is to provide a wrist watch namely the present invention, that keeps the time, scores, and game stats while playing the game of tennis. This is done by pressing fewer buttons that are larger in size, as well as having a larger watch face than your typical watch face. The reason this is done is to accommodate the information stored as well as to be given, and the electronic technology of the present invention.

Another objective, this wrist watch is water resistant due to the sweating of the tennis athletes. Also, it is shock absorbent due to the roughness of the sport. It is made of plastic, metal. Yet another objective is to provide a wrist watch that is simple to operate and inexpensive to manufacture. Yet another objective is that the present invention could be worn around the wrist sweatband due to the making of many types of large wrist watch bands. Many tennis Pros wear their watches and jewelry while playing.

To the accomplishment of the above and related objects, this invention may be more concrete and perceptible in the form illustrated in the accompanying drawing, attention being called to the fact, however, that the drawing is an illustration only.

Approximate dimensions are as follows: width is 1⅞ inch, length is 2⅛ inch, and the height is ½ inch.

Turning toFIGS. 1 and 2, the present invention10displays both conventional data (chronograph mode) and tennis data (tennis mode) on an alphanumeric display screen42. This may be an LCD display, LED display, electro luminescent display, or any other suitable display. The present invention10includes a computer (Item46onFIG. 3) which is operable in a chronograph mode and/or a tennis mode.

The present invention has eleven (11) operating means, which means could include buttons, switches, tabs, keys or the like which allow user controlled/selectable input of data/signals into a computer. The operating means include mode (14), LAP/RST (16), ST/SP (18), T-Mode (20), game 1 (22), game 2 (24), clear (30), light (34), player 1 (36), player 2 (38), and aces (40). The mode button, dual function time/date set button14is used to set the time and date in a manner similar to a conventional watch. The lap/countdown timer button16allows the lap function to be used to time laps when the present invention is used as a chronograph. The countdown timer function is used to set tennis court time, tie breaks, and long sets due to overlapping time on the court and when set to go off in ten 90-minute increments an alarm will sound. The dual function alarm/chronograph set button18, shown as ST/SP onFIGS. 1-2, is used in a manner similar to a conventional watch. Tennis mode (T-Mode) button20is used to switch between display mode activities, e.g., time and date, and Tennis Mode functions which are: players 1 and 2 (36and38) buttons are used when a player has scored, then the score will be displayed on the alphanumeric display screen. Games 1 and 2 (22and24) buttons are used when a player is the winner of a game in a set. The ace button40is used when the server serves an Ace. The score seen on the alphanumeric display screen42is a sum of total points by both players within a game. The time is actual local time displayed on the alphanumeric screen42. The alphanumeric screen42has an electro luminescent background26. The alphanumeric screen42has three display regions including an upper region42, middle region58and lower region31. In region42the alphanumeric data is displayed. In region58the score is displayed. In region30the clear button is displayed.
