Abstract:
A putting training device comprising a putter module which is selectively attachable and detachable to a putter and a target module. The putter module includes at least one indicia viewable when a users head is substantially vertically above the module. The putter module further includes a signaling element and the target module including a receiving element, and an indicating element. In use, the putter is directed towards the target module. A golf ball is struck in the direction of the target module and the indicating element alerts the user of impact condition.

Description:
BACKGROUND 
   This device pertains to the field of golf in general and specifically to the art of putting. The art of putting consists of three major factors; posture and alignment at contact with the ball, tempo of the putting stroke and striking the ball with the club face perpendicular to target. Many attempts have been made in the past to devise a product that could alert the user in real time to the condition of these factors while they are practicing the art of putting. Some prior art has been successful by addressing only one or two of the factors, by incorporating the sensing means into a custom putter which is not legal for USGA tournament play, or by large expensive stationary devices.

   DETAILED DESCRIPTION 
   The putting training device described herein, addresses three major factors, The device is small, portable, can be affixed to any right handed putter  70  and will be affordable to most golfers. The benefit of this is that the golfer can practice putting (at home, at the office or on a putting green) with a putter they are accustom to, remove the training device and go play with the same putter. The device provides the user with instant feedback as to the temp of their putting stroke, the squareness to the target at impact with the ball  73  and posture and alignment at address. The device consists of two modules, the Putter Module ( FIGS. 1   a,    1   b,  and  1   c ) and the Target Module ( FIG. 2 ). Once the Putter Module ( FIG. 1   a,    1   b,    1   c ) is affixed to the shaft user&#39;s putter  70  and turned on, the user will notice a small green light (indicia)  8  that appears on the top of the Putter Module. The green light acts as a guide for the user and is provided for by a signaling element  20 . Preferably, the signaling element  20  comprises an infrared light source. It is also preferable if the light is generated by a light emitting diode. This light has a limited viewing angle and the users head must be directly over it to be seen. This is the posture most experts in the field feel is required at address to the ball to achieve proper alignment to the target. Next, the user will aim the face of their putter towards the target. When the Putter Module ( FIGS. 1   a,    1   b,    1   c ) aligns with the Target Module ( FIG. 2 ), the signaling element  20  connects with a receiving element  16  on the Target Module and an amber light  14  will appear on the target. Preferably, the receiving element  16  is an infrared receiver. Next, the user will take a few practice strokes, observing the green light  8  on the Putter Module ( FIGS. 1   a,    1   b,    1   c ). A pendulum element  32 , intermediate of the green light  8  and the outlet for the light from the housing, will physically occlude viewability of the light when a swing is off track or uneven in velocity. Therefore, if the green light (LED)  8  is constant, the users&#39; stroke is smooth and pendulum like. If the green light is intermittent, the stroke is jerky, indicating over acceleration or deceleration. The aperture  31  of green light  8  is tangent to the shutter( FIG. 4 ), which is located on the Putter Module. When the user is satisfied that their stroke is smooth, they will address the ball  73 . Again, a user will check their posture by observing the green light (LED)  8  on top of the Putter Module ( FIGS. 1   a,    1   b,    1   c ) and check the squareness of the face of the putter to the target by observing the amber light  14  on the Target Module ( FIG. 2 ). Next, a user will stroke the putt towards the target. At the moment of impact, the amber light  14  on the target will go out. If the putter was square to the target at impact, a green light (LED)  15  will appear on the Target Module ( FIG. 2 ). If the putter face was not square to the target, no light will appear. After a two (2) second delay, the Target Module ( FIG. 2 ) will again be ready to recognize an alignment signal from the Putter Module ( FIG. 1   a,    1   b,    1   c ). 
   The Putter Module ( FIGS. 1   a,    1   b,    1   c ) preferably consists of: a mounting bracket  1 , which attaches the Putter Module to the shaft  71  of the putter  70 , ( FIG.7 ). Clamp  2 , holds the mounting bracket  1  to the putter  70 . The pivot  3 , which allows the Putter Module to position itself perpendicular to the ground regardless of the lie angle of the putter. The aperture control  4 , varies the width of the beam projected by the Putter Module ( FIG. 1   a ) thru the lens  6 . A user may use the aperture control  4  to adjust the amount of light emitted through the aperture  31 , ( FIG. 5 ). The aperture  31 , ( FIG. 5 ) includes a cam  43 , bearing surface  42 , and indicador  41 . Housing  7 , contains the printed circuit board (described in schematic drawing  FIG. 3 ) and the battery door which allows for replacement of the battery. The Target Module ( FIG. 2 ) consists of a stand  11  and a housing  12 . Within the housing  12  is a printed circuit board, described by the schematic drawing ( FIG. 6 ). Preferably, the Target Module further includes a first and second light element of different colors. The printed circuit board on the front face of the target preferably comprises an ambar LED  14 , a green LED  15  and an infrared receiver  16 . The target ( FIG. 2 ) also has a target housing door  13  for easy replacement of the batteries. Those versed in the art will recognize the functions described in the schematic circuits shown in  FIG.3  and  FIG.6 . 
     FIG. 3  one exemplary embodiment of the Putter Module, describes the following functions:
     C 1 —capacitor—conditions the power supply provided by the battery B 1  thru switch S 1 .   R 8 &amp; 9 —resistors—provide a reference voltage to set the low battery indicator.   R 1 &amp;D 1 —Green LED &amp; current limiting resistor, provide the posture alignment indicator.   R 2 &amp;R 3 —resistors—provide a reference voltage to set the sensitivity of X 1 .   X 1 —Piezo element—converts the mechanical energy of the shock of impact with the ball to an electrical signal.   uC 1 —Microcontroller—signals a low battery condition by blinking D 1 , senses the impact of the ball via X 1  and times the impact signal generated by  1 C 1 .     1 C 1 —Quad nand gate—generates the alignment signal and impact signal impressed on the carrier signal sent by D 2 .   X 2 —Resonator—generates the 455 Khz. carrier signal.   Q 1 —Transistor—drives D 2 .   D 2 —Inferred emitting diode—sends the signal to the target.   
     FIG. 6 , one embodiment of the Target Module describes the following:
     PT 1 —Inferred detector—receives the signal from the Putter Module.   R 1 &amp;R 2 —Resistors—provide a voltage reference for the low battery function.   U 1 —Microcontroller—interprets the signal received from the Putter Module via PT 1  and determines which LED to illuminate (amber  14  and Green  15 ).   Q 1 &amp;Q 2 —Transistors—which drive their respective LED&#39;s.   D 1 &amp;D 2 —LED&#39;s display the alignment signal and the proper impact signal.
