Method and apparatus for evaluating a putt
First Claim
1. A system for evaluating a spin of a moving golf ball that is struck with a golf club, the system comprising:
- a golf ball comprising;
a golf ball body;
a motion sensor disposed within the golf ball body and configured to measure acceleration of the golf ball along each of three mutually perpendicular axis;
a processor disposed within the golf ball body and configured to determine spin of the golf ball based upon the acceleration measured by the motion sensor, the processor further configured to determine the backspin of the golf ball based upon a time rate of angular rotation of an acceleration vector about a horizontal axis; and
a transmitter disposed within the golf ball body configured to transmit data representative of spin of the golf ball; and
a display device comprising;
a receiver configured to receive data representative of the spin of the golf ball from transmitter;
a display configured to provide a representation of a measure of the spin of the golf ball, wherein at least one of the golf ball and the display device comprises a processor configured to determine the spin of the golf ball based upon the acceleration measured by the motion sensor.

Abstract
A method, system and golf ball determine the side spin and/or back spin of a golf ball to facilitate the evaluation of a putt. In one embodiment, a system includes a golf ball and an offboard display device. The golf ball includes a golf ball body, a motion sensor disposed within the golf ball body and configured to measure acceleration of the golf ball along each of three mutually perpendicular axis, and a transmitter within the golf ball body transmits data representative of spin of the golf ball. The display device includes a receiver and a display, and the receiver receives data representative of the spin of the golf ball from the transmitter and the display is configured to provide a representation of a measure of the spin of the golf ball.
