Abstract
The present invention relates to a method for monitoring the operating state of a device, including a communication circuit and antenna for wireless transmission of signals to and from a base device arranged on the device, including the steps of: transitioning between first and second operating states, wherein the first operating state corresponds to a position of an interfering object in spaced relation to the antenna and the second operating state corresponds to a position of the interfering object closer in relation to the antenna; interference of the signal transmission between the antenna and the base device by the interfering object when in its closer position, wherein the interfering object does not interfere with the signal transmission when in its spaced position; detection of at least one of the occurrence or lack of interference with the signal transmission for determination of a transition between the operating states.
