1. A game ball comprising;
- a magnetic-field sensor;
a reader of reading out the magnetic-field sensor;
an activation signal detector for detecting an activation signal; and
a controller for controlling the reader so that reading-out will be performed at a first sampling rate if an activation is detected on account of the activation signal, and reading-out will be performed at a second, smaller sampling rate if no activation is detected.

Abstract
A game ball wherein in the vicinity of a goal, or in a goal area, an electronic system is activated in the goal area by an activation signal, which may be a magnetic field or a radio signal, so as to subsequently facilitate, e.g., highly precise position measurement of the game device, or game ball.

12. A method of activating a game ball comprising a magnetic-field sensor, the method comprising:
-
detecting a ball activation signal; and controlling a reader for reading out the magnetic-field sensor, so that reading-out will be performed at a first sampling rate if an activation is detected on account of the activation signal, and reading-out will be performed at a second, smaller sampling rate if no activation is detected. - View Dependent Claims (13, 14, 15)

16. A computer program comprising a program code for performing a method of activating a game ball comprising a magnetic-field sensor, the method comprising:
-
detecting a ball activation signal; and controlling a reader for reading out the magnetic-field sensor, so that reading-out will be performed at a first sampling rate if an activation is detected on account of the activation signal, and reading-out will be performed at a second, smaller sampling rate if no activation is detected, when the program runs on a computer.
