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.

Abstract: A sports apparatus for monitoring spatial positions of players within a spatial playing region is provided. The sports apparatus includes personal monitors carried by the players, and a monitoring arrangement coupled in communication with the personal monitors for determining spatial positions of the personal monitors within the spatial playing region. The sports apparatus also includes a camera arrangement for capturing views of at least a portion of the spatial playing region for determining spatial positions of the players within the spatial playing region, and a data merging arrangement for merging position-measurement data generated by the monitoring arrangement and the camera arrangement to provide output information indicative of the spatial positions of the players within the spatial playing region.
