1. A game apparatus comprising:
- a game ball comprising a plurality of components fitted therein, said components comprising;
a magnetic-field sensor, wherein the magnetic-field sensor is configured to sense magnetic field values proximate to a goal;
a reader for taking readings from the magnetic-field sensor;
a radio transmitter for transmitting readings of the magnetic field values;
an activation signal detector for detecting an activation signal, wherein activation is triggered when a reading of a magnetic field intensity of read values exceeds a threshold value; and
a controller for controlling the reader so that whenever activation is detected on the basis of the activation signal, reading is operated at a first sampling rate, and if no activation is detected, reading is operated at a second, slower sampling rate.

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.

9. A method of activating a game ball comprising a magnetic-field sensor, the method comprising the steps of:
-
measuring a magnetic field using the magnetic-field sensor, wherein the magnetic-field sensor is configured to sense magnetic field values proximate to a goal; reading out measurement values from the magnetic-field sensor using a reader; transmitting the measurement values with a radio transmitter to an evaluation unit; detecting a ball activation signal, wherein activation is triggered due to the fact that the magnetic field intensity of the read magnetic field values has exceeded a magnetic field intensity threshold value; and controlling the reader for reading out the magnetic-field sensor, so that whenever activation is detected on the basis of the activation signal, reading is operated at a first sampling rate, and if no activation is detected, reading is operated at a second, slower sampling rate; wherein all said steps are performed by components contained within the game ball. - View Dependent Claims (10)

11. A non-transitory computer readable medium having stored thereon a computer program comprising a program code which, when executed by a computer, performs the the steps of:
-
measuring a magnetic field using the magnetic-field sensor, wherein the magnetic-field sensor is configured to sense magnetic field values proximate to a goal; reading out measurement values from the magnetic-field sensor using a reader; transmitting the measurement values with a radio transmitter to an evaluation unit; detecting a ball activation signal, wherein activation is triggered due to the fact that the magnetic field intensity of the read magnetic field values has exceeded a magnetic field intensity threshold value; and controlling the reader for reading out the magnetic-field sensor, so that whenever activation is detected on the basis of the activation signal, reading is operated at a first sampling rate, and if no activation is detected, reading is operated at a second, slower sampling rate; wherein all said steps are performed by components contained within a game ball.
