Abstract: Disclosed are method and system for automatic identification of at least one player. The system and method are associated with a processing unit, and at least one projectile having a wireless interface and at least one sensor. The sensor collects sensor data at a first moment of time before release of the projectile by the player and communicates the sensor data to the processing unit. The processing unit collects and analyses the sensor data to identify similar data, associates such data to a player, and stores the associated data. The sensor collects further sensor data at a second moment of time before release of the projectile by the player, which second moment of time is later than the first moment of time and communicates the further sensor data to the processing unit. The processing unit compares the further sensor data to the stored associated data to identify the player.

Abstract: An apparatus including a data acquisition device, a processing unit, a memory and an output device. The data acquisition device obtains at least one attribute of a shot of a basketball towards a basket. The at least one attribute is sensed by at least one sensor carried by the basketball or derived from signal output by the at least one sensor. The memory contains instructions to direct the processing unit to determine whether the shot is a made basket shot or a missed basketball shot by comparing the at least one attribute of the shot to one or more predetermined signature characteristics of a made basket. The output device presents output to a person based on the determination of whether the shot is a made basket shot or a missed basket shot.

Abstract: A sports apparatus is provided. The sports apparatus includes a computing device, an imaging device, and a projectile. The projectile includes a configuration of sensors for collecting sensor data, and a wireless interface for communicating the sensor data to the computing device. The computing device is operable to use the sensor data to detect a beginning of an event of interest, and to use the imaging device to start recording a sequence of still images along an expected trajectory of the projectile based on the detected beginning of the event of interest. The sequence of still images comprises at least one image where the projectile is detectable. Moreover, the computing device is operable to use the at least one image and the sensor data to determine a time-parameterized trajectory of the projectile, and to determine whether the time-parameterized trajectory intersects a specified region in space.
