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 unitary athletic device having a housing comprising:
a retaining mechanism configured to retain the housing on either a first athlete or apparel worn by the first athlete during an athletic activity;at least one sensor configured to generate, in real-time, athletic movement data from physical movement of the first athlete during the athletic activity;a processor;a transceiver configured to communicate in real-time during the athletic activity with a computer device; anda non-transitory computer-readable medium comprising computer-executable instructions that when executed by a processor cause the processor to perform at least:
in real-time, process with the processor, the athletic movement data of the respective at least one sensor to calculate athletic metric data of the first athlete; and a computer device that is not worn by the first athlete or on the first athlete during the athletic activity configured to communicate electrical signals relating to the athletic metric data with the athletic devic, wherein said computer device and said athletic device are specifically paired, defined by at least one of a wired serial connection and wireless bonding which enables the athletic device to authenticate the identity of the computer device prior to communicating the electrical signals therewith, and
wherein said computer device is operable to automatically upload activity data, defined as data generated from one or more electrical signals relating to the athletic metric data from the physical movement of the athletic housing over a network to a remote server configured to store said activity data to enable interactive communication whereby uploaded activity data can be retrieved over the network.
