Abstract:
1. A golf swing measurement and analysis system comprising: a) a golf club comprising a shaft, a club head, and the club head further comprising a club head top surface and a club head face; b) a first module that is: c) a means for aligning said first module on said club head top surface defining an alignment of said first module, and a means for attaching said first module to said club head top surface; d) said second module that is located at said predetermined location, said second module comprising a housing that contains electronics to provide electronic functions comprising: e) a means of receiving said second module second transmitted measurements at a computational engine having one or more input/output port formats and a display; f) a golf swing model stored on the computational engine comprising: g) a first computational algorithm that operates on said computational engine that interprets second module second transmitted measurements, said first module transmitted measurements, and said acceleration measurements within boundary conditions of said golf swing model, detects if said first module alignment is misaligned, calibrates said first module transmitted measurements based on said acceleration measurements; h) a second computational algorithm that operates on said computational engine that interprets said first module transmitted measurements and said acceleration measurements or said first module transmitted measurements and said acceleration measurements calibrated by the first computational algorithm within boundary conditions of said golf swing model to define a dynamically changing relationship time line between an inertial axes coordinate system defined by said golf swing model and said measurement axes coordinate system during a golf swing; and i) a third computational algorithm that operates on said computational engine that interprets said first module transmitted measurements, said signal strength measurements made at said first module, said second module second transmitted measurements, and said second signal strength measurements made at second module to define time delay between a first module measurement acquisition time and a second module measurement acquisition time; and further uses said time delay and signal strength measurements to define a dynamic spatial relationship between a time line of said club head travelling on a non-linear travel path and the predefined location correlated to said dynamically changing relationship between said inertial axes coordinate system and said measurement axes coordinate system during a golf swing.
