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 address to 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.
SUMMARY OF THE INVENTION
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 including a signaling element and the target module including a receiving element, and an indicating element.

DETAILED DESCRIPTION
The putting training device described herein, address the three major factors, is small, portable, can be affixed to any right handed putter and will be affordable to most golfers. The benefit of this is that the golfer can practice their 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 a putter that conforms to USGA rules. 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 and posture and alignment at address. The device consists of two modules, the Putter Module (FIGS. 1a, 1b, and 1c) and the Target Module (FIG. 2). Once the Putter Module (FIG. 1a, 1b, 1c) is affixed to the users putter and turned on, the user will notice a small green light 8 that appears on the top of the Putter module. 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 (FIG. 1a, 1b, 1c) acquires the Target Module (FIG. 2), an amber light 14 will appear on the target. Next, the user will take a few practice strokes, observing the green light 8 on the Putter module (FIG. 1a, 1b, 1c). If the green light (LED) 8 is constant, the users' stroke is smooth and pendulum like. The aperture of green light 8 is tangent to the shutter (FIG. 4). If the green light is intermittent, the stroke is jerky, indicating over acceleration or deceleration. When the user is satisfied that their stroke is smooth, they will address the ball. Again, they will check their posture by observing the green light (LED) 8 on top of the Putting module (FIG. 1a, 1b, 1c) 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, they will stroke the putt towards the target. At the moment of impact, the amber light 14 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 2 second delay, the Target Module (FIG. 2) will again be ready to recognize an alignment signal from the Putter Module (FIG. 1a, 1b, 1c). The Putter Module (FIG. 1a, 1b, 1c) consists of: The mounting bracket 1, which attaches the module to the putter. The clamp 2, which holds the mounting bracket to the putter. The pivot 3, which allows the module to position itself perpendicular to the ground regardless of the lie angle of the putter. The aperture control 4, which varies the width of the beam projected by the target module (FIG. 1a) thru the lens 6. And the housing 7, which 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 housing 12. Within the housing 12 is a printed circuit board, described by the schematic drawing (FIG. 6). On the printed circuit board and appearing on the front face of the target are; an Amber LED 14, a Green LED 15 and an IR 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 FIGS. 3 and 6. FIG. 3, the Putter Module, describes the following functions:
- C1-capacitor—conditions the power supply provided by the battery B1 thru switch S1.
- R8&9-resistors—provide a reference voltage to set the low battery indicator
- R1&D1—Green LED & current limiting resistor, provide the posture alignment indicator
- R2&R3—resistors, provide a reference voltage to set the sensitivity of X1
- X1—Piezo element, converts the mechanical energy of the shock of impact with the ball to an electrical signal
- uC1 —Microcontroller, signals a low battery condition by blinking D1, senses the impact of the ball via X1 and times the impact signal generated by 1C1
- 1C1—Quad nand gate, generates the alignment signal and impact signal impressed on the carrier signal sent by D2
- X2—Resonator, generates the 455 Khz. carrier signal
- Q1—Transistor, drives D2
- D2—Inferred emitting diode, sends the signal to the target
FIG. 6, the Target Module describes the following:
- PT1—Inferred detector, which received the signal from the Putter Module
- R1&R2—Resistors which provide a voltage reference for the low battery function
- U1—Microcontroller, interprets the signal received from the Putter Module via PT1
- And determines which LED to illuminate (Amber 14 and Green 15)
- Q1&Q2—transistors, which drive their respective LED's
- D1&D2—LED's which display the alignment signal and the proper impact signal
