Abstract: A golf club head includes a club face with at least one impact sensor, where the sensor has a passive piezoelectric element that is integrated into the club face, the passive piezoelectric element being able to generate a signal when an impact force is applied to the club face. An energy storage assembly includes a battery, a capacitor, or both. An energy harvesting assembly includes a signal divider with at least one input and at least two outputs, the at least two outputs providing a known ratio of a given input signal, wherein the at least one input of the signal divider is electrically coupled to one or more of the piezoelectric elements and a first of the at least two signal divider outputs is electrically coupled to the energy storage assembly.

Abstract: The presented invention relates to a method for determining the effectiveness of a golfer's swing without the requirement of the club head making contact with a golf ball. More specifically, the present invention relates to a measurement and analysis system comprising a first module that attaches to the club head and captures measurement receiver signal strength data during the entire swing time line and may capture motional data on same time line, further first module wirelessly communicates bi-directionally with a second module that is further connected to a user interface device and computational engine where feedback results are derived and conveyed to the golfer. The system provides comprehensive feedback for a swing characterization time line referenced to the spatial domain using receiver signal strength measurements that may be in combination with motional and dynamics orientation measurements.

Abstract: An integrated golf club and analysis system that measures and analyze the performance characteristics of both: 1) a free golf swing without impact with a golf ball and 2) a golf swing with ball impact analysis. Free swing analysis provides critical information needed to analyze swing style so that dynamics swing characteristics optimization can be evaluated throughout the entire swing without ball impact, while impact analysis provides critical information on ball impact location on the club face, however, they cannot be measured simultaneously since ball impact eliminates the ability to identify the swing metric peaks such as velocity if it were to occur after ball impact. To achieve both, an integrated electronics golf club head comprises multiple types of sensors for measuring club head motion, impact and spatial location information with a weight and balance of a regulation golf club head.

Abstract: An integrated golf club comprising standard golf club shaft and an integrated electronics system golf club head apparatus for directly measuring physical parameters of the golf club head motional acceleration swing forces and golf club head face and golf ball impact forces and further processing those measurements and transmitting the measurement data wirelessly to a user interface device. The integrated electronics system golf club head comprises several optimized assemblies that support electronic measurement, processing and wireless communication functions that are integrated with a customized golf club head shell and club face to provide a golf club head with physical properties that are substantially similar to that of a regulation play golf club head of same type. The user interface device that receives wirelessly transmitted data further processes the data and provides the golfer with useful golf swing and impact metrics in multiple different user selectable formats.

Abstract: The present invention relates to a method for determining the effectiveness of a golfer's swing requiring no club contact with the golf ball. The measurement and analysis system comprises an attachable and detachable module, that when attached to a golf club head measures three dimensional acceleration data, that is further transmitted to a computer or other smart device or computational engine where a software algorithm interprets measured data within the constraints of a multi-lever variable radius golf swing model using both rigid and non-rigid levers, and further processes the data to define accurate golf swing metrics. In addition, if the club head module is not aligned ideally on the club head a computational algorithm detects the misalignment and further calibrates and corrects the data.
