Detecting and providing player information with sensor at the player side
First Claim
1. A game ball for detecting and providing information assigned to players of a ball game, wherein the game ball contains:
- a magnetic field generator for generating an alternating magnetic field, wherein the magnetic field generator contains at least three coils that are electrically actuated such that a resulting magnetic field vector rotates in three dimensions, wherein the frequency at which the resulting magnetic field vector rotates is considerably higher than a rotation frequency of the game ball that is possible during the game;
a transceiver for receiving radio signals which are transmitted in response to a detection of the generated alternating magnetic field and which contain an ID which can be assigned to a player, and for transmitting collected player information;
a control unit for evaluating received radio signals and for assigning timestamps to IDs of received radio signals;
a source of energy; and
a memory for writing and reading out player information based on the IDs with assigned timestamps.

Abstract
A system for detecting and providing information assigned to soccer players, wherein the system contains a soccer ball (130) comprising a centrally arranged magnetic field generator (142) for generating an alternating magnetic field (150); a transceiver (148) for receiving radio signals (160) and for transmitting collected player information; a control unit (144) for evaluating received radio signals and assigning timestamps to IDs of received radio signals; a source of energy; and a memory for storing and reading out player information based on the IDs with assigned timestamps; and a device (120) for sensing the generated magnetic field in a soccer shoe and for transmitting an ID assigned to the device, comprising a magnetic field sensor (122) for sensing and measuring the magnetic filed (105); a control unit (124); and a transmitting unit (128) for transmitting a radio signal (160) which contains the ID assigned to the device (120), wherein the transmitting unit is actively supplied with energy, and wherein the radio signal is transmitted under control by the control unit.

6. A method for detecting and providing player information using a sensor at the player side, the method comprising the steps of:
-
generating, with at least three coils that are electrically actuated, a magnetic field in a game ball, wherein a resulting magnetic field vector rotates in three dimensions, and wherein the frequency at which the resulting magnetic field vector rotates is considerably higher than a rotation frequency of the game ball that is possible during the game; detecting the magnetic field with a magnetic field sensor of a device mounted in a playing device of a ball game, wherein the playing device can be assigned to a player; transmitting a radio signal by the device, wherein the radio signal contains an ID assigned to the device; and receiving the radio signal including the ID in the game ball. - View Dependent Claims (7, 8, 9)
