Athletic performance monitoring systems and methods in a team sports environment

摘要

Systems, apparatuses, and methods estimate the distance between a player and a ball by transmitting a chirp (sweep signal) to a radio tag located on the ball. During the chirp, the frequency of the transmitted signal is changed in a predetermined fashion. The radio tag doubles the transmitted frequency and returns the processed signal to a transceiver typically located on the player. The currently transmitted frequency is then compared with the received frequency to obtain a difference frequency from which an apparatus may estimate the distance. The apparatus may simultaneously receive the processed signal from the radio tag while transmitting the sweep signal.

主权项

1. An athletic monitoring system comprising:
a transceiver configured to communicate with a plurality of body-worn athletic devices comprising at least a first athletic device and a second athletic device, each of the plurality of athletic devices respectively configured to be uniquely associated and releasably attached to a corresponding plurality of players during performance of an athletic activity; a processor; a display unit configured to display athletic information; and a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor perform at least:
receive, in real-time during an athletic activity, athletic motion data collected from a sensor of the first athletic device while releasably attached to a first player and athletic motion data from a sensor of the second athletic device while releasably attached to the second player; process, with the processor, the athletic motion data from the first athletic device to create a first measurement of a first athletic metric for the first athlete during the athletic activity; process, with the processor, the athletic motion data from the second athletic device to create a second measurement of the first athletic metric for the second athletic activity; deriving, with the processor, during the athletic activity, that the first measurement meets a threshold criteria that the second measurement does not meet; determine, with the processor, an identity of the first player that is uniquely associated with the first athletic device; and display, on the display unit during performance of the athletic activity, that is viewable to a plurality of individuals, the first measurement of the first athletic metric and the identity of the first player uniquely associated with the first athletic device.
