System and method for detecting ball possession by means of passive field generation
First Claim
1. Device (130) for the detection of a ball possession by means for detecting a magnetic field in a playing device (100) of a ball game, wherein the magnetic field is generated by at least one permanent magnet (110) in the playing device, wherein the device can be associated to a player of a ball game and the means for magnetic field detection comprise:
- a magnetic field sensor (210); and
a control unit (220) coupled to the magnetic field sensor to receive a sensor signal from the magnetic field sensor, and which is adapted to detect whether the sensor signal was caused by the magnetic field of the at least one permanent magnet in the playing device, and for outputting information about the detection.

Abstract
System for ball possession detection, which contains a device (130) comprising means for detecting a magnetic field in a playing device (100) of a ball game, wherein the magnetic field is generated by at least one permanent magnetic (110) in the playing device, wherein the device can be associated to a player of a ball game and the means for magnetic field detection comprise a magnetic field sensor (210) and a control unit (220), and a method for ball possession detection, wherein the magnetic field sensor detects a magnetic field (310), the control means measures the magnetic field strength of the detected magnetic field (320) and detects (330) whether the magnetic field was caused by the at least one permanent magnet in the playing device and outputs information about the detection (350), as well as a ball (100) that contains at least one permanent magnet.
