Abstract: A system for a vehicle, which has a battery, a DC-DC converter, a DC-AC converter, an electric motor, and a switch. The battery is connected to the DC-DC converter and the DC-AC converter is connected to the electric motor. The switch is arranged between the DC-DC converter and the DC-AC converter, and the switch is designed, in a first switching state, to electrically connect the DC-DC converter and the DC-AC converter and to permit an exchange of electrical energy between the battery and the electric motor in order to carry out a traction process. The switch is designed, in a second switching state, to electrically isolate the DC-DC converter and the DC-AC converter, to connect the battery to an electrical charging station, and to permit an exchange of electrical energy between the battery and the electric charging station in order to carry out a charging process.

Abstract: A transparent pixel matrix, a screening layer, and a control circuit are included in a display apparatus. The control circuit displays a graphic object on the pixel matrix. The screening layer includes individually switchable segments arranged behind the pixel matrix and the segments are switchable with respect to their transparency between a minimum value and a maximum value. The control circuit selects the graphic object based on an input by the user. The control circuit signals the graphic object is selected by operating a first segment among the segments arranged behind the selected graphic object as a selection segment, with the minimum value of transparency or with the maximum value of transparency, and by operating a second segment among the segments as a background segment in a complementary fashion with respect to the selection segment, with the maximum value of transparency or the minimum value of transparency.

Abstract: A method for producing a workpiece threaded hole by a tapping tool, with a drilling stroke, in which the rotating tapping tool is driven into the workpiece in a drilling direction to a nominal drilling depth, and so forming a thread-free pilot hole, and with a tap-ping stroke in which the tapping tool produces an internal thread in the pilot hole with a tapping feed rate and a tapping speed synchronized therewith. The drilling stroke is followed by a reversing stroke in which the tapping tool is guided out of the pilot hole in a reversing direction opposite to the drilling direction. The tapping tool is then radially displaced by a radial offset in an offset stroke. Then, in the tapping stroke, the radially controlled, rotating tapping tool is guided in a circular rotary motion along a circular path around the hole axis.
