ABSTRACT:
The time and position of a golf club head are sensed photoelectrically at selected stations along a practice swing, and corresponding characteristics of the swing and the resulting ball flight are computed electronically and displayed to the player. The lateral club position is sensed accurately by continuous strip sensors at spaced stations near the ball for computation of the swing direction. All light received by the strip sensors is respectively focused to light diffusing surfaces from which sensors read the amount of light focused thereon. The club head attitude at impact is determined by three triangularly spaced sensors spaced along the club face. The club head height at impact is determined by two directional-sensitive sensors spaced longitudinally with the club head path and having their paths of directional sensitivity crossing in the longitudinal direction. A plurality of these height detectors are also utilized to determine whether the club head is descending or rising at the time of impact. Club head velocity is also detected and all of these club head characteristics of swing are computed electronically into ball flight characteristics which are displayed. The electronic computing circuitry is not activated until a predetermined club head velocity is detected thereby eliminating erroneous readings of preliminary club head swings when addressing the ball.
