Patent ID: 8303428

Claim:
A short game training device for use with a golf club, the golf club having a club face for striking a golf ball, the short game training device comprising: an accelerometer having at least two axes including an X-axis and a Y-axis orthogonal to said X-axis, each of said X and Y axes capable of measuring linear forces experienced along their respective axes, and each of said X and Y axes having a polarity such that forces experienced in one direction along each one of said axes are registered as a positive value and forces experienced in the opposite direction along said axes are registered as a negative value, a fastener for removably attaching said accelerometer to a golf club so that said X and Y axes are each approximately in parallel alignment with the club face, and so that said X and Y axes are each disposed at approximately a 45° angle with respect to a substantially vertical plane when positioning the golf club to address the golf ball with the club face aligned perpendicularly to a selected aim line, said vertical plane parallel to said aim line, the polarity of both of said X and Y axes pointed either upward or downward such that horizontal movement lateral to said aim line will register as a positive measurement on one of said X and Y axes and as a negative measurement on the other of said X and Y axes a detectable alarm, and a microprocessor for calculating differences in the values of the forces measured by said X and Y axes during a timed interval after the golf ball has been addressed by the golf club, said timed interval commencing with the beginning of a stroke of the golf club, and for activating said alarm during said timed interval when said differences indicate lateral movement relative to said aim line.
