First Claim
Patent Images
1. A system for measuring the motion of a golf club swung by a golfer, the system comprising:
- a golf club comprising a shaft and a golf club head, the shaft having a plurality of radiofrequency tags, the plurality of radiofrequency tags comprising at least an upper shaft radiofrequency tag and a lower shaft radiofrequency tag;
a plurality of radiofrequency sensors positioned in proximity to a golf ball to create a swing field for reception of radiofrequency signals from the plurality of radiofrequency tags as the golf club is swung through the swing field to strike the golf ball;
wherein the plurality of radiofrequency sensors captures a speed and motion of the golf club as the golf club is swung through the swung through the swing field.

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 device that enables the capturing of the speed and motion of the swing. The invention uses two antennas, one transmitting and one receiving. The power of the radar wave is low. The wavelength will be on the order of a millimeter.

12. A method for measuring the motion of a golf club swung by a golfer, the method comprising:
-
swinging a golf club through a swing field at a golf ball, the golf club comprising a shaft and a golf club head, the shaft having at least one radiofrequency tag thereon and the golf club head having at least one radiofrequency tag thereon, the swing field created by a plurality of radiofrequency sensors positioned equidistance from the golf ball; receiving a plurality of radiofrequency signals at the plurality of radiofrequency sensors from the at least one radiofrequency tag on the shaft and the at least one radiofrequency tag on the golf club head; and detecting an orientation of the golf club head at impact with the golf ball, the speed of the swing and the flight of the golf ball after impact from the plurality of radiofrequency signals received at the plurality of radiofrequency sensors.
