  • Patent number: 3945646
    Abstract: An athletic implement, such as a golf club, has a shaft and a club having a ball-striking face. Multiple accelerometers are positioned in the club so as to measure acceleration in directions normal and parallel to the face and parallel to the shaft, when the implement is swung to strike a ball. Signals representative of acceleration measured in each direction are then transmitted to a remote console where these signals are processed by vector computation to provide indicia representative of the swing, such as club face position, club velocity and acceleration.
