Method and system for monitoring movement of a sport projectile
First Claim
1. A sports apparatus for monitoring movement of a basketball, comprising:
- a sensor disposed within the basketball;
a wireless interface disposed within the basketball for communicating sampled data signals from the sensor;
a portable communication device coupled in wireless communication with the wireless interface of the basketball for receiving the sampled data signals from the sensor, the sampled data signals indicative of a motion of the basketball;
wherein the portable communication device comprises a processor having a memory including programming instructions that when executed by the processor are configured to cause the processor to;
detect a sensor signal from the wireless interface, the sensor signal comprising the sampled data signals from the sensor;
determine a first trajectory of the basketball from the sensor signal; and
determine if the first trajectory comprises one or more of small changes, large changes, rapid changes or slow changes in amplitude over time in the sampled data signals of the motion of the basketball;
determine if the first trajectory comprises a shot taken with the basketball, wherein the shot taken by the basketball is identified by the sensor detecting one or more slow changes in the sampled data signals over time and a rapid change in amplitude of the sampled data signals followed by a period of one or more slow changes in the sampled data signals over time;
determine if the first trajectory comprises passage of the basketball through a goal structure by detecting a change in an angular velocity of the basketball without the basketball being rapidly laterally displaced and without the basketball'"'"'s rotation characteristic being temporally abruptly altered; and
determine if the first trajectory comprises an impact of the basketball with an object.

Abstract
A sports apparatus for monitoring movement of a sport projectile includes a sensor and a wireless interface disposed within the sport projectile for communicating sampled data signals from the sensor, a portable communication device in wireless communication with the wireless sensor for receiving sampled data signals from the wireless sensor, the sampled data signals indicative of a motion of the sport projectile. The portable communication device includes a controller having a memory including programming instructions that when executed by the processor cause the controller to detect a sensor signal from the wireless interface, determine a motion characteristic of the sport projectile from the motion characteristic from the sensor signal, and determine if the motion characteristic is passage of the sports projectile through a goal structure, motion of the sports projectile after a shot or an impact of the sport projectile with an object.
