<P>PROBLEM TO BE SOLVED: To provide a device for automatically counting the number of strokes without requiring large-scale equipment. <P>SOLUTION: A golf ball 1 includes an acceleration sensor 2 for detecting the acceleration of an object, and a radio module 3 for transmitting a signal from the acceleration sensor 2 as radio data. The acceleration sensor 2 transmits a signal to the radio module 3 when detecting that the acceleration has exceeded a certain acceleration, so that the radio module 3 transmits the radio data and a receiver for receiving the radio data receives the radio data from the golf ball 1 and counts the number of strokes automatically. <P>COPYRIGHT: (C)2012,JPO&INPIT |
