Abstract: The present invention relates to a computer program product, method, and device for automatic positioning of a charge plug, arranged on a movable arm of a ground station, into a socket of a vehicle unit of an electric vehicle arranged thereabove, where the device comprises a control unit, which is designed and configured to control the movement of the movable arm and/or the charge plug, and a sensor device communicating with the control unit for detecting the positioning of the charge plug relative to the socket.

Abstract: A computer mainboard includes components intended for operating a computer, a control logic that controls voltage supply of the computer mainboard, and a connector plug that receives at least one supply voltage (+12V DC) specified for the computer mainboard, an auxiliary voltage (Vin_ext_DC) and a monitoring signal (Vin_ext_OK) that indicates the presence of an external supply voltage (VEXT_DC, VEXT_AC) that has a predetermined specification, wherein the control logic is configured to detect the monitoring signal (Vin_ext_OK) via the connector plug and, after detection of the monitoring signal (Vin_ext_OK), to generate a first control signal (EN_REG_EB#) and output it to the outside via the connector plug so that, depending thereon, an external voltage supply device can be activated to provide the at least one supply voltage (+12V DC) specified for the computer mainboard from the external supply voltage (VEXT_DC, VEXT_AC).
