摘要： Various embodiments of the teachings herein include a sensor unit for a contactless actuator of an adjustable vehicle element. The sensor unit may include: a carrier element for mounting to a vehicle; a first sensor device attached to the carrier element and having a first capturing area; and a second sensor device attached to the carrier element and having a second capturing area. When mounted on the vehicle, the first sensor device is arranged closer to a floor of the vehicle than the second sensor device; and the first capturing area extends further back with respect to a forward direction of travel of the vehicle than the second capturing area.

摘要： Various embodiments include determining a level of a surface of a fluid and/or for determining a quality of the fluid in a fluid container. An example apparatus comprises a sound transducer module having two sound transducers designed to receive and emit sound signals in such a manner that a superimposition sound signal results when the sound signals are superimposed, and a reference element arranged in the fluid at a predefined distance from the sound transducer module and is designed to reflect the superimposition sound signal. The sound transducer module is designed, by superimposing the at least two sound signals, to emit the superimposition sound signal both in a first direction to the surface of the fluid and in a second direction to the reference element, said second direction running at a predetermined sound signal angle with respect to the first direction.

摘要： Various embodiments of the teachings herein include a method for operating a battery device having a number of battery cells arranged in a battery housing. The method may include: detecting a fluid concentration of a predetermined fluid in an interior of the battery housing;
comparing the detected fluid concentration to a specified concentration threshold; adapting a maximum admissible operating temperature of the battery device if the detected fluid concentration exceeds the concentration threshold; and operating the battery device such that the maximum admissible operating temperature is not exceeded.
