Abstract: A system and method for shot tracking disclosed herein. The system preferably includes a golf club and a receiver. The golf club preferably includes an active RFID transponder, a power source, a switch and an accelerometer.
Abstract: The present invention is a method for transmitting a RFID signal while conserving battery power of a circuit. The method comprises charging a capacitor using a battery. The battery is in electrical communication with a resistor and the resistor is in electrical communication with a capacitor and a load switch. The load switch is in electrical communication with an enabler and a microprocessor. The microprocessor is in electrical communication with a radiofrequency component. The load switch is closed, allowing power drawn from the capacitor to flow to the radiofrequency component.
Abstract: A club shaft that can be installed in a club head permanently or can be installed in clubs with interchangeable shaft features is disclosed herein. The invention is a measurement system that enables the capturing of the speed and motion of the golfer's swing. The invention uses infrared reflectors positioned on a golf club and an array of infrared sensors.
Abstract: The present invention provides a method of manufacture and design such that very small detail features can be produced within the groove profile on an iron or wedge. The advantage in being able to do this is that spin will be enhanced for a variety of shot types and conditions when striking a golf ball with cover composed of a urethane-based material.

Abstract: A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product with a thermoplastic polyurethane cover in a solution containing an isocyanate functionality reactive material. The precursor product is then removed from the solution and heated to remove solvent. The precursor product is then placed in an isocyanate solution. The precursor product is then removed and heated to remove solvent to prepare the precursor product for finishing.

Abstract: An out-sole assembly for a golf shoe. The outsole assembly includes an internal base member composed of EVA, an inner frame member composed thermoplastic polyurethane subjected to an isocyanate solution, an external base member composed of a thermoplastic polyurethane, a dual looping frame composed of a thermoplastic polyurethane, and a plurality of spike members.
Abstract: A golf GPS device is disclosed herein. The device includes a GPS unit, a memory for storing a plurality of aerial images of a golf course, a display for displaying the plurality of aerial images, a user input for inputting a plurality of location points on an aerial image of the plurality of aerial images displayed on the display, and a processor comprising means for determining a distance between any two points on a golf course.
Abstract: A method, system and golf ball are provided to determine the deceleration of a golf ball and, in turn, the speed of a green. The system may include a golf ball and an offboard display device. The golf ball may include a golf ball body, a motion sensor disposed within the golf ball body to measure acceleration of the golf ball along each of three mutually perpendicular axes, and a transmitter disposed within the golf ball body to transmit data representative of deceleration. The display device may include a receiver to receive data representative of the deceleration of the golf ball from transmitter and a display to provide a representation of the deceleration of the golf ball. At least one of the golf ball and the display device may include a processor to determine deceleration of the golf ball based upon the acceleration measured by the motion sensor.
Abstract: A club shaft that can be installed in a club head permanently or can be installed in clubs with interchangeable shaft features is disclosed herein. The invention is a measurement system that enables the capturing of the speed and motion of the golfer's swing. The invention uses magnetic material positioned on a face of a golf club head and an array of magnetic sensors.
