Golf swing analysing apparatus
First Claim
1. An apparatus for detecting a golf swing'"'"'s deviations from desired ideal performance characteristics, comprising:
- (a) at least one golf club comprising a club head, said club head comprising a club face;
(b) at least one permanent magnet attached to said club head at a predetermined location and orientation relative to said club face;
(c) a detector array comprising a ball-position indication, said detector array further comprising at least one sensor for detecting a magnetic field and producing at least one electrical signal upon detecting said magnetic field, said sensor located in a fixed position relative to a notional line corresponding to the desired ideal path of said club head over said ball position indication, said sensor comprising a magnet-sensitive boundary unit comprising at least one elongate portion in a fixed location and orientation relative to said notional line;
(d) circuitry electrically connected to said detector array for converting said electrical signals; and
(e) readout means, connected to said circuitry, to provide an indication of detected differences between the actual path of said club head and said desired ideal path.

Abstract
A golf swing analyzing apparatus for detecting, measuring and/or displaying differences from a desired ideal golf swing is described. The apparatus comprises (a) one or two permanent magnets in spaced recess in one or more golf clubs, (b) a number of loops in a planar detector array close to the notional or actual ball position and (c) a readout device for picking up the various signals created as the magnets cross straight line portions of the loops and conveying them to indications of swing angle, club face angle, club face tilt, impact zone at the club face, speed acceleration, rake and so on. The magnitudes of speed, height sensitivity, and magnet strength permit such golf diagnostic equipment to be readily constructed and give usable displays of figures of (on a screen) outcome of the notional golf stroke.

53. A mat for detecting a golf swing'"'"'s deviations from desired ideal performance characteristics, comprising:
-
a ball support surface; a ball position indication on said ball support surface; a detector array of electrical loops at predetermined locations and orientation in relation to said ball position indication; said loops being electrically insulated from one another and collectively permitting at least two separate signals to be detected by movement relative to said ball position indication of a golf club having a permanent magnet attached thereto at a predetermined location and orientation; each of said loops further comprising a magnet-sensitive boundary unit comprising at least one elongate portion in a fixed location and orientation to said ball position indication; and signal transmission means for transmitting said electrical signals to a readout device.
