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.
