Abstract: A method for producing a bipolar plate strand comprises: providing a first and a second unipolar plate strand, the unipolar plate strands comprising a plurality of webs and a plurality of channels extending between two adjacent webs in each case, guiding the unipolar plate strands towards a rolling gap of a pair of rollers of a rolling device provided with rolling structures, local heating of one surface area of a surface of at least one of the unipolar plate strands, the surface area immediately before or upon entry of the unipolar plate strands into the rolling gap being heated to a joining temperature, and joining the unipolar plate strands at the at least one surface area to form a bipolar plate strand during transport of the unipolar plate strands through the rolling gap under the action of pressure.

Abstract: An input device, especially for a vehicle, comprises a display to display an operating element, a touchscreen arranged above the display for recognition of the position of touching of an operating surface of the touchscreen, a force sensor connected to the touchscreen for measurement of the force exerted on the operating surface of the touchscreen, and a control to generate a warning during touching of the operating surface of the touchscreen in the region of display of the operating element or during pressing on the operating surface of the touchscreen in the region of display of the operating element, and to generate a control command assigned to the operating element, if, after generation of the warning, a force that exceeds a force limit value is exerted on the operating surface.

Abstract: An input device, especially an input device for a vehicle, includes a display for optical display of information, a touchscreen arranged above the display for input of commands by touching an operating surface of the touchscreen and a control for optical display of additional or other information on the display during at least a second simultaneously occurring touching of the operating surface.

Abstract: An input device, especially for a vehicle, comprises a touchscreen to enter commands by touching an operating surface of the touchscreen or by pressing on the operating surface, an actuator to move the touchscreen in at least one direction, and a control module to control the actuator as a function of the speed of a touching movement over the operating surface.
