A method for monitoring a ball used for an athletic activity includes detecting movement of the ball using a sensor module coupled to the ball, determining a characteristic of the movement of the ball, comparing the characteristic to a known profile, and determining a second characteristic using the comparison.
Claims11
A method for determining a speed of a ball used for an athletic activity, the method comprising:
- sensing acceleration data, using a sensor module coupled to the ball;
- determining a drag force applied to the ball, based on the acceleration data;
- comparing the drag force with a drag profile that expresses drag as a function of ball speed, wherein the drag profile is based on experimental data;
- and
- determining the speed of the ball based on the comparison.
