Swing performance analysis device
First Claim
1. A swing performance analysis device comprising a sole single axis accelerometer securable on a shaft of a golf club substantially adjacent to the golf club'"'"'s head to measure centripetal acceleration, the accelerometer being arranged to communicate with a processor, wherein the processor is arranged to accept one or more parameters on the swing to be analysed and measurement data on the swing from the accelerometer, the processor being operative to determine the radius of curvature of the swing calculate in dependence on the one or more parameters and to determine one or more attributes on the swing in dependence on the radius and measurement data, the one or more attributes including a slowing distance (d):
-
d=((vpk+vi)*(ti−
tpk))/2Where;
vpk=peak tangential velocity=√

Abstract
A swing performance analysis device (10) is described. The device (10) includes a sole single axis accelerometer securable to an entity (60, 70) to be swung to measure centripetal acceleration. The accelerometer is arranged to communicate with a processor (30). The processor (30) is arranged to accept one or more parameters on the swing to be analysed and measurement data on the swing from the accelerometer, the processor being operative to determine the radius of curvature of the swing calculate in dependence on the one or more parameters and to determine one or more attributes on the swing in dependence on the radius and measurement data.
