Abstract: In a method for testing an audio communication system of an aircraft, it is detected whether a jack plug of a headset is plugged into a jack of the audio communication system. Subject to the condition that no jack plug is detected, an electrical connection is made between an audio output of the jack and a microphone input of the jack by means of a test bridge circuit provided for at the jack. Furthermore, a test input signal is applied to an audio input connected to the audio output of the jack, and a test output signal is tapped off at a microphone output connected to the microphone input of the jack. The test output signal is used to ascertain a functional state of the audio communication system. Furthermore, an aircraft having an audio communication system is described.

Abstract: A system for determining a cabin layout in a cabin of a vehicle, includes a system for contactless transfer of power with primary magnetic elements and secondary magnetic elements that each overlap with at least one primary magnetic element. Based on sequentially providing power to primary magnetic elements and measuring at least one electric value in the powered primary magnetic element overlapping states of secondary magnetic elements and primary magnetic elements can be determined. By determining overlapping states for all primary magnetic elements in the cabin the number and positions of all secondary magnetic elements and all vehicle components attached thereto can be collected. The system avoids powering two contiguous primary magnetic elements to prevent a wrong determination of an overlapping state.

Abstract: A system for the contactless transfer of energy and data includes a transfer path with a primary coil and with a secondary coil. The primary control unit is designed to lead data-modulated first alternating-voltage signals of a first frequency range into the primary coil. The secondary control unit is designed to receive the first alternating-voltage signals of the first frequency range from the secondary coil, and to demodulate the modulated-on data.
