Sensor or actuator operating method monitors field produced by resonance winding converting magnetic field into electrical energy during operation of electronic communications device for preventing interference

摘要

The operating method uses a resonance winding (4,5,6) and a rectifier (10,11,12) for providing electrical energy from a magnetic field and an electronic communications device (17) with a radio transmitter and/or receiver for transmission and/or reception of information signals. The field provided by the resonance winding is monitored during the operating periods of the communications device, for preventing interference caused by operation of the sensor or actuator, e.g. by connecting a load (19) across the output terminals of the rectifier. An independent claim for a device for operation of a sensor or actuator is also included.
