Abstract
Abstract A simple golf exercising aid device for notifying a golf player immediately after any head-up. The device comprises sound pickup means for an impacting sound caused by the impact of a club head against a golf ball, first means which compares, with a threshold value, a waveform within a predetermined frequency band out of the signals provided by the sound pickup means and outputs the result after a predetermined delay time, a motion sensor made up of an earth magnetic field sensor or an angular velocity sensor, for converting the motion of a golf player's head into an electrical signal, and second means which rectifies and then differentiates the output signal of said motion sensor, and which compares the differentiated output with a threshold value. Said motion sensor is mounted a portion of the golf player's head, and judgment output is provided when the timings of the outputs from the two means agree.

Claim 1
Independent Claim
135 words
A golf exercising aid device comprising sound pickup means for an impacting sound caused by the impact of a club head against a golf ball, first means which compares, with a threshold value, a waveform within a predetermined frequency band out of the signals provided by the sound pickup means and outputs the result after a predetermined delay time, a motion sensor which converts the motion of a golf player's head relative to the earth's magnetic field into an electrical signal, and second means which rectifies and then differentiates the output signal of the motion sensor, and which compares the differentiated output with a threshold value, whereby with said motion sensor attached to a portion of the golf player's head, judgment output is provided when the timings of the outputs from said two means agree.
