Referring now to the drawings, and firstly to FIGS. 1 and 6, the putter training device includes a putter data module 1 in conjunction with a magnet 15 and magnet retainer 16 adhesively attached to a lower surface of a head of a golf putter 2. When ball 3 is struck, the putter data module 1 collects data on the position of the putter club face 14 and putter path 43 to the ball.
Ref. FIGS. 2, 3, 4, 8, 9, 14, 15 & 16 and 26, the putter data module 1 (shown in FIGS. 9 and 14 with graphics panel 12 and deck plate 46 removed) includes a printed wiring board assembly 38 to collect and display data to the golfer. This assembly 38 is captured between the deck plate 46 and the base 11 using a plurality of screws 41. The deck plate 46 is covered with a graphics panel 12 with a printed graphic line to indicate center line plane 18 and various labels for the controls and indicators. The device 1 is placed on the floor or ground (the natural position for putting) and is prevented from slipping by rubber feet 40. The printed wiring board assembly 38 includes a printed wiring board 32 which electrically connects and constrains the system battery 34, a microphone 31, a speaker 30, a microprocessor 33, a left club face sensor 19, a right club face sensor 20, a ball sensor 21, a left target LED illuminator 25, a right target LED illuminator 26, a center line LED indicator 27, an error left LED indicator 28, an error right LED indicator 29, three embedded magnetic sensors 44, a magnetic-actuated power switch 8, a manual power switch 7, various other electronic components (not shown), a battery charger connector 35, and a combined switch made from the metronome on/off switch 9 and metronome frequency adjustment switch 10.
Ref. FIGS. 1, 4, 5, 8 & 12, the ball 3 placement is fixed by a ball rest dimple 6 on the deck plate 46. An aperture in the graphics panel 12 exposes the ball rest dimple 6 to the bottom of ball 3. A ball guide 5 is molded into deck plate 46 and extends through slotted apertures 5a in graphics panel 12. This allows the ball 3, using putter 2, to be pushed onto the putter data module 1 via ball ramp 4 and then further guided by ball guide 5 to ball rest dimple 6.
Ref. FIGS. 2, 9, 14 and 16, to detect when a ball 3 is present and to start system functions as per FIG. 25 flow chart, the ball sensor 21 detects the ball 3 by means of an infrared transmitter 47 illuminating the ball 3 surface and an infrared receiver 48 detecting this illumination. This sends a signal to the microprocessor 33 on printed wiring board 32 that enables target 22 and the metronome, a software function in microprocessor 33 as shown in FIGS. 25 and 26. This metronome produces a rhythmic tone from speaker 30 on printed wiring board 32. This metronome is adjusted and enabled from a ganged switch including a metronome on/off switch 9 and metronome frequency adjustment switch 10. The metronome sets a tempo for the golfer's back swing to develop a more consistent putt.
The golfer's proper head position directly over the golf ball 3, and therefore body position, is established by maintaining sight of target 22. This fixes the golfer's body position for every putt. This target 22 is illuminated by means of left target LED illuminator 25 and right target LED illuminator 26 reflecting off reflective left target wall 23 and reflective right target wall 24. Target wall 23 and reflective right target wall 24 are constructed as two wall segments at a fixed angle relative to the center line plane 18. This allows 360 degree target acquisition based on reflective light.
Ref. FIGS. 21, 22, 23 & 24, as the golfer's head moves from the desired position a light feedback system provides viewable indicia of inconsistent head and body positioning. FIG. 21 shows what the golfer sees when in the correct position directly over the ball with no light visible due to reflective left target wall 23 and reflective right target wall's 24 perpendicular plane relative to the visual plane. FIG. 22 shows the golfers head north of desired position, (ref. compass rose FIG. 22), which allows reflective left target wall 23 to come into the golfer's view. The visible light indicates off-target to the north. FIG. 23 shows the golfer's head north and west of desired position, (ref. compass rose FIG. 23), which allows east half of reflective left target wall 23 to come into the golfer's view. The visible light indicates off target to the northwest. FIG. 24 shows the golfer's head north and east of desired position, (ref. compass rose FIG. 24), which allows west half of reflective left target wall 23 to come into the golfer's view. The visible light indicates off-target to the northeast. As the golfer's head moves southward, the same light feedback as describe is indicated using right target wall 24. This feedback allows the golfer's head to center on target 22, regardless of the golfer's standing position for a right- or left-handed golfer.
Ref. FIGS. 2, 6, 7, 8, 9, 14, 15, 16, 17, & 18, the putter path 43 for the last 150 mm before the putter 2 club face 14 impacts ball 3 is determined by three embedded magnetic sensors 44 placed at equal intervals along the centerline plane 18. The embedded magnetic sensors 44 include two hall effect devices 45 located under the graphics panel 12, one on the right and one on the left of center line plane 18.
Ref. FIGS. 10, 11, 12, & 13, the putter 2 is configured with a magnet 15 molded into magnet retainer 16 that is affixed to the putter 2 by means of an adhesive pad 17. The magnet 15 is placed at the on putter 2 opposite the putter center of gravity indicator 39. This center of gravity indicator 39 is typically marked on most putters to indicate the sweet spot (center of gravity) and is the desired ball impact zone for consistent putts. Ref. FIG. 5, during the forward stroke, for 150 mm (or some pre-defined distance) before ball 3 impacts, the putter travels exactly down putter path 43 coincidental to center line plane 18 to putt the ball 3 in the desired ball path 42.
Ref. FIG. 18A, in the desired putt stroke, the putter 2 travels along center line plane 18 and magnet 15 travels directly between the two hall effect devices 45 that comprise each of the embedded magnetic sensors 44. In this relationship, the magnet 15 imparts magnetic flux lines 50 to each hall effect device 45 equally. The hall effect device 45 output voltage is controlled by the magnet flux acting on the device 45. This information is sent to microprocessor 33. If all three embedded magnetic sensors 44 show the putter path 43 to track down the center line plane 18, the microprocessor 33 commands center line LED indicator 27 to illuminate. Ref. FIG. 7, if the putter 2 center of gravity indicator 39 and magnet 15 is not coincidental to center line plane 18, (in this case left of the center line plane 18) the magnet 15 imparts magnetic flux lines 50 more to the left hall effect device 45 and less to the right hall effect device 45. The microprocessor 33 reads this voltage and commands error left LED indicator 28 or error right LED indicator 29 to illuminate based on the side of the center line plane 18 before impact with ball 3.
Ref. FIGS. 2, 8, 9, 14, & 19, as the club face 14 on putter 2 impacts ball 3, microphone 31 detects the impact and sends this information to microprocessor 33. At this point in time, the club face 14 on putter 2 passes over the left club face sensor 19 and right club face sensor 20. Ref. FIG. 20, the club face sensor 19 and right club face sensor 20 include an infrared transmitter 47 and an infrared receiver 48 pair. Ref. FIG. 5, upon impact as detected by microphone 31, the microprocessor 33 interrogates each sensor 19 and 20 to determine when the time a signal was received from reflective surface 49 on putter 2. If left club face sensor 19 and right club face sensor 20 signals were coincident in time, the microprocessor 33 sends three beeps to speaker 30 indicating to the golfer that the club face 14 was perpendicular to center line plane 18. In this case ball 3 follows ball path 42 along center line plane 18, hopefully to the hole. Ref. FIG. 6, if right club face sensor 20 signal was detected before left club face sensor 19, the microprocessor 33 sends two beeps to speaker 30 indicating to the golfer that the club face 14 was not perpendicular to center line plane 18 and the ball path 42 will be left of desired path to hole. Ref. FIG. 7, if left club face sensor 19 signal was detected before right club face sensor 20, the microprocessor 33 sends one beep to speaker 30 indicating to the golfer that the club face 14 was not perpendicular to center line plane 18 and the ball path 42 will be right of desired path to hole.
Ref. FIGS. 1, 2, 5, 8, 9, 25 & 26, in normal operation, ball 3 is placed on the putter data module 1, the putter 2 with the magnet 15 attached moves over magnetic actuated power switch 8, (or manually switched on with manual power switch 7), to wake up the system, activate the body alignment target 22 and start the metronome. The golfer aligns his head with target 22 base on not seeing any light from reflective left target wall 23 or reflective right target wall 24. The putter 2 is swung back, in time with the metronome, and then forward to strike ball 3.
Microphone 31 detects the impact of putter face 14 and ball 3. After a short delay, the end-of-swing indicator, including flashing left target LED illuminator 25 and right target LED illuminator 26 and a short beep from speaker 30, completes the putting stroke. At this time the golfer has had full body follow-through and can move out of the constraint of the body alignment target 22. Based on time signals from left club face sensor 19 and right club face sensor 20, the putter face 14 angle at impact with ball 3 is reported to the golfer using tones from speaker 30. The golfer also receives the putter path 43 feedback based on putter center of gravity indicator tracking the center line plane 18. Tracking down the center of center line plane 18 will illuminate center line LED indicator 27. Otherwise the error left LED indicator 28 or error right LED indicator 29 will illuminate based on the side of the error. When ball 3 is replaced on putter data module 1 the cycle is repeated. Otherwise, if an expected act is not initiated by the golfer in a predetermined time, the device falls asleep to conserve battery power.

It is therefore intended that the following appended claims and claims hereinafter introduced are interpreted to include all such modifications, permeations, additions and subcombinations that are within their true spirit and scope.
