Abstract:
1. A diagnostic golf club system comprising: a diagnostic golf club comprising a club head, a shaft attached to the club head, a plurality of strain gauges attached to the shaft, the strain gauges capable of measuring data related to the golf club during a golf swing, and an internal memory device including a non-volatile flash buffer memory capable of receiving and storing data from the strain gauges; a computer located separate and spaced apart from the diagnostic golf club for processing the data stored in the internal memory device; and an interface mechanism removably coupled to the diagnostic golf club for providing communication between the diagnostic golf club and the computer, the interface mechanism including a connection plug having a plurality of pins for connection to a plurality of receptors on the diagnostic golf club, wherein the internal memory device is capable of storing data for multiple swings of the diagnostic golf club until the data is uploaded to the computer via the interface mechanism, and wherein the computer uses the data related to the diagnostic golf club during a golf swing to calculate six independent forces and moments, the six independent forces and moments including axial force, transverse shear forces, bending moments, and torsion.
