[0044]The combined weight of all assemblies of the integrated electronics system golf club head is substantially equal to that of a regulation play club head of similar type. In addition, the mounting location of all pieces of all assemblies either internal to the club
Problems solved by technology
The system in U.S. Pat. No. 7,736,242 does not teach or suggest an integrated electronic system golf club head that integrates impact sensors into the club head face in combination with acceleration measurement sensors located in the club head and further does not teach an antenna system that utilizes the electrical properties and shape of the club head as an integral component element of the antenna system design to increase power efficiency and further operating time duration based on storage capacity of energy device.
The system does not provide for a method of free swing analysis with the ability to relate a measurement time line to a predetermined spatial reference location.
Plutt's device does not provide for an imbedded impact sensor array in the clubface that functions in conjunction with internal three dimensional g-force sensors to provide a superset of time varying spatial force impact contours of the clubface with club head acceleration force parameters that can be calibrated for highly accurate spatial and force measurement.
Plutt's device is susceptible to location inaccuracy due to the removable constraint of the sensors and is susceptible to sensor d

second embodiment
[0221]Turning to FIG. 22, an example chart 2300 of multiple sensor outputs 2310 are shown, spanning both an impact period 2320 and a vibration period 2330. The x axis in this example represents time. Samples may be taken, for example, simultaneously every 4 microseconds in one embodiment. The y axis in this example represents the amplitudes of the power signals output from each of the six sensors 2310. These amplitudes indicate the amount of pressure on each respective piezoelectric sensor. The amplitude values may be multiplied by a predetermined amount to convert the amplitude samples into standard pressure measurement units, such as pascals (Pa). This calculation may also take into account calibration, which may involve a second multiplier in one embodiment or a sensor specific multiplier that takes into account the ratio in a The pressure measured by each pressure sensor element, in combination with known club face flexibility clamping profile of the club face / club head structu...
first embodiment
[0235]FIG. 10 shows a club head shell 2000 with exemplary varying wall thickness profile type for the benefit of minimal weight and robust structural integrity. The club head shell 2000 (without the club face) has an outer surface 50 and an inner cavity 2001 and inner cavity 2001 has an inner surface (not labeled). This first embodiment of the club head shell structure defines a wall thickness profile that comprises areas of increased thickness 2002 and allows the predetermined and predefined outer surface 50 shape or contour to remain constant and unchanged. Exemplary areas of increased thickness 2002 are shown protruding into the inner cavity 2001 as interconnected ribs and are only shown for a small portion of the total shell for clarity of illustrative drawing purposes, however, would be implemented throughout the club head shell structure in predetermined area locations of the shell 2000 based on known applied stress and acceptable strain requirements. The areas of increased th...

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.
