An ion trap device includes a dielectric substrate and a via hole extending through the dielectric substrate from a first main surface of the dielectric substrate to a second main surface of the dielectric substrate. The ion trap device further includes an electrically conductive etch stop layer arranged on the first main surface of the dielectric substrate, wherein the etch stop layer covers the via hole. The ion trap device further includes a metal layer of an ion trap at least partially arranged on the etch stop layer and an electrically conductive material arranged in the via hole, wherein the etch stop layer electrically couples the electrically conductive material and the metal layer.

A photoacoustic gas sensor (100) comprises a substrate (110) and a measurement cell (120) within the substrate. An emitter (130) is mounted on the substrate (110) and configured to emit light into the measurement cell (120). A sensor (140) is mounted on the substrate (130) and configured to measure pressure variations in the measurement cell (120).

A photoacoustic gas sensor (100) comprises an emitter (110) configured to emit light, a sensor (120) configured to measure pressure variations and a measurement cell (130) enclosing the emitter and the sensor. At least a first ventilation opening (140a) and a second ventilation opening (140b) connect the measurement cell (130) with an environment (150).

Provided is an apparatus for controlling one or more function of a toilet. The apparatus includes processing circuitry configured to receive radar data of a radar sensor integrated into the toilet and determine movement parameters of a user relative to the radar sensor based on the radar data. Furthermore, the processing circuitry is configured to determine, based on at least part of the movement parameters of the user, whether the user is within a predefined area. In response to determining that the user is within the predefined area, the processing circuitry is configured to determine a movement trajectory of the user based on the movement parameters of the user. In addition, the processing circuitry is configured to determine, based on the movement trajectory, whether the user is slowing down while approaching the toilet. In response to determining that the user is slowing down while approaching the toilet, the processing circuitry is configured to trigger the one or more function of the toilet.

The present disclosure relates to a sensor arrangement for detecting a substance (112) on a windshield (104). The sensor arrangement comprises a mm-wave signal generator (102) configured to provide a first mm-wave signal. The sensor arrangement further comprises a receiver (106) and a processing circuit (108). The receiver (106) is configured to receive a second mm-wave signal. The processing circuit (108) is configured to determine information indicating the substance (112) on the windshield (104) based on the first mm-wave signal and the second mm-wave signal.

A method for operating a radar sensor in a vehicle, the radar sensor comprising a radar transceiver operating in an operating frequency range. The method comprises generating within the radar sensor an information related to an orientation of the radar sensor and determining an orientation of a transmission of the radar transceiver based on the information related to the orientation of the radar sensor. Further, the method comprises selecting a frequency sub-band of the operating frequency range of the radar transceiver depending on the orientation of the radar transceiver for transmitting radar signals
