Abstract: A battery arrangement with a sensor device for detecting a gas discharge from at least one battery cell of the battery arrangement. The battery cell has a releasable cell degassing opening. The sensor device for detecting the gas discharge has a sensor unit with an electrical line which can be subjected to a test voltage. The sensor unit is arranged in such a way that a gas escaping from the cell degassing opening impinges on the sensor unit, and the electrical line can be damaged by a gas flowing out of the cell degassing opening. In particular, the sensor unit is designed in such a way that the electrical line can be damaged by the outflow pressure of a gas discharging from the cell degassing opening in the event of thermal runaway of the battery cell.

Abstract: A display device includes a flexible screen device and a pivot mechanism. The flexible screen device is movable between a stowed position, in which the flexible screen device is bent along a circular arc and stowed in a housing, and a use position, in which the flexible screen device protrudes at least partially from the housing. The pivot mechanism is configured to move the flexible screen device between the stowed position and the use position, and includes a motor and a pivot arm. The pivot arm is rotatably mounted on a foot region of the flexible screen device so as to be pivotable about an axis of rotation. The pivot arm is configured to receive a torque from the motor to move the foot region along the circular arc. The flexible screen device is thereby alternately pushed into the use position and pulled into the stowed position.

Abstract: A display device that can be worn on the head of a vehicle occupant of a motor vehicle is controlled to display a virtual environment within which the vehicle occupant wearing the display device virtually moves according to a detected movement of the motor vehicle. A potential stopping point of the motor vehicle is determined. A deceleration of the motor vehicle is detected within a given environment of the potential stopping point and the display device is controlled to output a virtual scene staging within the virtual environment which causes a deceleration of the virtual movement of the vehicle occupant within the virtual environment corresponding to the deceleration of the motor vehicle.
