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: A golf club assembly includes at least one sensor assembly, the sensor assembly being operable to sense at least motion and impact of a golf club head and a processor communicatively coupled to the sensor assembly, the processor being operable to sample data from the sensor assembly at a first rate, receive a signal indicating motion of the golf club head, and sample data from the sensor assembly at a second rate different from the first rate upon receiving the signal indicating motion of the golf club head.

Abstract: A golf club head may include a face with an embedded monolith having first and second sensors for measuring impact with a golf ball. The first and second sensors may output positive and negative pressure signals at the same time, caused by the impact, with the negative pressure indicating an outward bowing of the monolith whereas the positive pressure indicates an inward compression. These positive and negative values may be captured over the duration of impact and used to create a time-varying impact pressure profile with increased accuracy. The club head may also include a mechanism for placing a static pressure on the monolith, increasing negative pressure sensitivity and adjusting the ability to measure negative impact pressures away from the contact point on the club face.

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: A measurement device may include one or more inductive structures coupled to a signal processor that measures changes in inductance. As the inductive structure moves in relation to an external conducting object, inductance changes may occur in the inductive structure. By analyzing the changes in inductance, the system may determine spatial relationships concerning the measurement device. Additionally, at least one inductive structure may be placed behind a conductive impact surface, allowing for measurement of impact characteristics without disturbing the impact surface. The measurement device may be used in or on sports equipment, such as a golf club.

Abstract: A method and integrated golf club apparatus for directly measuring physical parameters of the golf club head motional acceleration swing forces, golf club head face, golf ball impact forces, and subsequent calculations of other metrics useful to a golfer's understanding of the effectiveness of his or her golf swing and impact result in totality. The physical parameters that are directly measured include three dimensional motion force vectors of club head prior to, during and after impact and full impact pressure force profiles across the golf clubface with respect to time. The force measurements are made by at least one piezoelectric or differential capacitance based acceleration g-force sensor internal to the club head and pressure impact force sensors integrated into the clubface.

Abstract: A measurement device may include one or more piezoelectric elements that output power signals. The device may split each power signal, analyzing a first portion of the signal while supplying a second portion to an energy storage assembly. A processor may dynamically adjust the first and second portions of each power signal to change how much of each power signal is used for signal processing versus energy storage, and may make the adjustments based on detected activities and/or pre-programmed timelines. The device may be used in or on sports equipment, such as a golf club.

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.
