<p><P>PROBLEM TO BE SOLVED: To smoothly advance a game by eliminating a searching time of a ball and hitting the ball soon after finding it easily even when the trouble shot of the ball into woods or a deep rough happens, so that interruption of a play is prevented at each hole. <P>SOLUTION: A small transmitter is put in the golf ball to transmit a signal by operating while it is used by applying shock such as hitting. By receiving the signal of the ball by a receiver by going to the surrounding of a place where the ball has fallen, the direction is clearly shown by a straight line, etc., on a screen for finding the ball easily. A transmission life is within 6 hours, and a transmission range and a receiving range have an about 20 m diameter. Thus, overlapped receiving with an old ball, etc., which is left as unprocessed is prevented. Further, even if the overlapped receiving of the balls is performed, an approximate position can be guessed, thereby the ball can easily be found. <P>COPYRIGHT: (C)2003,JPO</p> |
