Abstract
Analysis of a golfer'"'"'s putting stroke towards a target-hole (2) is derived by an analyzer (12;50) from sensor-signals representative of initial ball-speed and direction, using accumulated sets of historical putting-data, each set of historical data including initial putted ball-speed and direction and the resultant ball-speed and direction in approach to the target-hole (2), together with representation of whether the putt was successful. Initial ball-speed and direction is sensed by opto-electronic sensors (45) responding to back-reflection of infrared beams (13) from retro-reflectors (22-26) on the putted ball (1;20;52), or, is using retro-reflectors (71-73; 77,75) on the putter (3;51;70;74). Resultant ball-speed and direction in approach to the target-hole (2), and whether the putt is successful, is sensed by a monitor (7) from infrared beams (8-10).

- 16. A method for putting analysis comprising accumulating sets of historical data from respective putts of a ball towards a target of a putting surface, each set of data comprising data relating to the initial speed and direction of the ball as putted and the speed and direction of the ball in approaching the target together with representation of whether the putt was successful, deriving in relation to a golfer'"'"'s putting stroke signal-representations of resultant initial putted-ball speed and direction, providing an analysis-result by determining from the signal-representations of resultant initial putted-ball speed and direction and the sets of historical data whether the initial putted-ball speed and direction are in combination consistent with achieving a successful putt on the putting surface, and providing indication dependent on the analysis-result.
- 27. A system for putting analysis comprising means for accumulating sets of historical data from respective putts of a ball towards a target of a putting surface, each set of data comprising data relating to the initial speed and direction of the ball as putted and the speed and direction of the ball in approaching the target together with representation of whether the putt was successful, sensor means for deriving in relation to a golfer'"'"'s putting stroke signal-representations of resultant initial putted-ball speed and direction, means for providing an analysis-result from the signal-representations of resultant initial putted-ball speed and direction and the sets of historical data whether the initial putted-ball speed and direction are in combination consistent with achieving a successful putt on the putting surface, and means for providing indication dependent on the analysis-result.
