Embodiment Construction

[0010] According to certain embodiments, an embedded sensing system is disposed in optimally selected locations of a sporting implement, such as a golf club, a baseball bat, a tennis racket, a hockey stick, a boxing glove, etc. The embedded system includes sensors that are small in size, accurate and capable of high speed measurements in order to reliably and dynamically measure, record and / or transmit the measurements to a processor. According to certain embodiments, the sporting implement includes sensors as described herein, an embedded micro controller or digital signal processor (DSP), a memory, an optional display and an embedded communication module. The sensors include one or more magneto-resistive (MR) magnetic field or compass sensors.

[0011] According to certain embodiments, the MR sensors are used for dynamically measuring the three-dimensional magnetic vectors through the motion of the sporting apparatus, as in a golf swing or swing of a hockey stick, for example. For p...

Abstract

A sporting apparatus used by a person for engaging in a sporting activity. The sporting apparatus includes a single or multiple embedded MR sensors for measuring magnetic vectors of the earth magnetic field for dynamically recording a path of motion of the sporting apparatus in real time. In a preferred embodiment, the sporting apparatus further includes one or multiple MEMS accelerometer sensors for sensing acceleration of a designated portion of the sporting apparatus for measuring impact velocity as the designated portion impacting a ball. In a specific embodiment, the sporting apparatus is a golf club wherein the accelerometer sensors are disposed adjacent to the grip side of the shaft for sensing the impact of the club head against a golf ball. In another specific embodiment, the golf club further includes a magnetic field sensor disposed near the grip end of the golf club for measuring a motion path of the golf club.

Description

PRIORITY CLAIM [0001] This application claims benefit of Provisional Application 60 / 583,876, entitled, Real-Time Measurements For Establishing Database of Sporting Apparatus Motion and Impact Parameters, filed Jun. 28, 2004, the entire contents of which is hereby incorporated by reference as if fully set forth herein, under 35 U.S.C. §119(e).FIELD OF THE INVENTION [0002] The present invention relates generally to design of microelectronic systems and methods for providing real-time measurements of the motion and impact parameters of sporting equipment. More particularly, this invention is related to the use of micro-electro-mechanical system (MEMS) and magneto-resistive (MR) sensors and other microelectronics installed in sporting equipment such as a golf club, a hockey stick, a boxing glove, a tennis racket or a baseball bat to obtain real-time motion parameter measurements for analyzing a player's performance and for establishing diagnostic and training databases associated with a...
