DEVICE, SYSTEM AND METHOD FOR IDENTIFYING AN ARTIFICIALLY GENERATED MAGNETIC FIELD ON A MOBILE TELEPHONE

摘要

The invention relates to a device for identifying an artificially generated magnetic field (2) in a mobile telephone (1), comprising at least one magnetic field sensor (3) suitable for measuring the magnetic field of the earth (2); at least one evaluating unit (4) for evaluating a measurement signal of the magnetic field sensor on the basis of the artificially generated magnetic field (2); and at least one first communication unit (8) that is connected to the evaluating unit (4) for transmitting a first signal via a first data channel (7) to a control unit (9) as a consequence of the evaluation of the measurement signal.
