  • Patent number: 9681035
    Abstract: A method and apparatus (100) are disclosed for wirelessly communicating by a proximity communication circuitry comprising an antenna with a proximate device (200) according to a proximity communication protocol. The proximity circuitry is disabled when not needed. Voltage in the antenna caused by an electromagnetic power signal (222) is detected when the proximity communication circuitry is disabled. The detection of voltage is independent of whether the electromagnetic signal (222) complies with the proximity communication protocol. An event is triggered in response to the detected voltage. Correspondingly a method and device (200) for externally controlling the apparatus (100) are disclosed in which a user command is detected and responsively to the user command, an electromagnetic signal (222) is transmitted to the apparatus (100) for triggering the event. The electromagnetic signal (222) has a regular wave form.
