Sports monitoring system and method
First Claim
1. A sports monitoring system, wherein the system includes:
- one or more projectiles having an associated motion sensing arrangement for generating one or more motion-indicative signals, and a data recording arrangement for recording the one or more motion-indicative signals as a function of time;
sensor units for a plurality of players to wear, each having a motion sensing arrangement for generating one or more motion-indicative signals, each motion sensing arrangement including a microphone and the one or more motion-indicative signals including sound recorded by the microphone, and a data recording arrangement for recording the one or more motion-indicative signals as a function of time; and
a data processing arrangement for receiving data pertaining to the motion-indicative signals from at least one of the one or more projectiles and the plurality of sensor units, for performing a temporal correlation of the data pertaining to the motion indicative signals including the sound recorded by the microphone, by using a sliding dot product to identify a substantial match among the data from at least one of the one or more projectiles and the data from the plurality of sensor units, and for using the substantial match among the data to determine one or more periods of time when actual mutual contact among the plurality of players has occurred, the motion indicative signals of the at least one projectile and the at least one player sensing unit further comprising acceleration, rotation, or orientation information.

Abstract
A sport monitoring system includes a projectile(s), sensor units for one or more players to wear, and a data processing arrangement. The projectiles are useable in a game played by players. Each projectile has a motion sensing arrangement for generating one or more motion-indicative signals, and a data recording arrangement for recording the motion-indicative signals as a function of time. Each sensor unit is provided with a motion sensing arrangement for generating a motion-indicative signal(s), and a data recording arrangement for recording the motion-indicative signals as a function of time. The data processing arrangement receives data pertaining to the motion-indicative signals from at least one of the projectiles and/or at least one of the sensor units. The data processing arrangement performs a temporal correlation of the data to determine one or more periods of time when the projectiles are likely to be spatially closely associated with the players.
