Sport Ball Athletic Activity Monitoring Methods and Systems

摘要

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.

1. A method for determining speed of an object used for an athletic activity, the method comprising:
sensing acceleration data, using a sensor module coupled to the object; determining a drag force applied to the object, based on the acceleration data; comparing the drag force with a drag profile that expresses drag as a function of object speed; and determining speed of the object based on the comparison.
