Abstract
A method for a contactless transmission of electric energy and/or an electric signal between a wall and a wing fastened to the wall includes providing a first coil fastened to the wall and a second coil fastened to the wing which are actively inductively connected to each other. A control signal is applied to the first coil within a control time interval to induce a first signal in the second coil, which is then detected. A second control signal is applied to the second coil within the control time interval to induce a second signal in the first coil, which is then detected. A fault signal is generated if the first or second control signal, or a part thereof, is not applied during the control time interval, or if the first or second signal, or a part thereof, is not detected during the control time interval.
