Abstract:
A system comprises an inertial sensor, a processor connected to the inertial sensor, and a memory device connected to the processor. The inertial sensor includes an accelerometer with three degrees of freedom in acceleration and has three degrees of freedom in rotation. The processor is configured alone or in combination with a linked microprocessor to generate stroke profiles describing acceleration and rotation based on signals from the accelerometer, and the memory device is configured to store the stroke profiles.

Claim (Index 41):
A motion tracking and stroke analysis method comprising:\n sensing acceleration of a system with an inertial sensor comprising an accelerometer with three degrees of freedom in measurement of acceleration; sensing angular velocity of the system with the inertial sensor, the inertial sensor further with three degrees of freedom in measurement of angular rotation; with one or more processors in communication with the inertial sensor:\n generating time histories the time histories describing the acceleration and angular velocity of the system; \n identifying pulse features within the time histories; and \n generating individual stroke profiles by segmenting the time histories based on time matching of the pulse features, wherein the acceleration and angular velocity define characteristics of the individual stroke profiles; \n storing the individual stroke profiles in memory, wherein the individual stroke profiles are divided into stroke classes based on the corresponding characteristics, the stroke classes defining a stroke repertoire; estimating state vectors for converting the individual stroke profiles into stroke trajectories representing reconstructed flight paths, the state vectors describing position, velocity and orientation of the system during stroke interactions; and determining impact forces and linear and angular momentum transfer from the system to a ball and from the ball to the system during the stroke interactions, wherein a ball strike causes a simultaneous change in linear and angular momentum of the system.
