Abstract
Abstract A golf practicing apparatus includes a platform; a target mounted on the platform for receiving practice of golf shots; a display panel for indicating distance information, hook-slice information, and push-pull information; and electronic circuitry responsive to movement of the target for actuating the display panel. The target comprises a simulated golf ball and a stem which are supported for rotation about a first axis extending through the ball and the stem, a second axis extending perpendicularly to the first axis, and a third axis extending perpendicularly to the second axis and in the plane of the first axis. In operation, the speed of rotation of the target about the second axis is sensed to provide distance information, the direction and amount of rotation of the target about the first axis is sensed to provide hook-slice information, and the direction and amount of rotation of the target about the third axis is sensed to provide push-pull information. Rotation of the ball and stem about the first axis is detected by an assembly including a cam and conventional breaker point assemblies. Rotation about the second axis is detected by a system including a lamp assembly, a phototransistor, and a rotatable opaque shutter including two spaced apart holes which permit two sequential light pulses to reach the phototransistor. Rotation about the third axis is detected by a system including a lamp assembly and a rotatable opaque shutter which uncovers one or more phototransistors arranged in a V-shaped array.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
A golf practicing apparatus comprising: a target comprising a simulated golf ball and a stem depending therefrom; a shaft extending perpendicularly to the stem of the target; first bearing means for supporting the end of the stem of the target remote from the simulated golf ball on the midportion of the shaft and for permitting free rotation of the ball and the stem about a first axis extending therethrough; a yoke comprising a pair of opposed bifurcations extending from a supporting end; second bearing means for supporting the opposite ends of the shaft on the bifurcations of the yoke and for permitting pivotal movement of the shaft, the first bearing means, and the stem and the simulated golf ball of the target about a second axis extending through the shaft; third bearing means for supporting the end of the yoke remote from the bifurcations and for permitting pivotal movement of the yoke, the second bearing means, the shaft, the first bearing means, and the stem and the simulated golf ball of the target about a third axis extending through the yoke; and remote sensing means wholly independent of any physical contact with the yoke and responsive to pivotal movement of the yoke about the third axis for generating an error signal.
