Abstract: A device for sequentially switching at least one first and at least one second Venetian blind, the slats of which can each be synchronously rotationally moved by means of at least one coupling rod in order to open and close the blinds. The device includes an actuator for generating a rotational movement of the slats through 80° to 90°, a coupling for rotatably coupling the actuator to a slat of the first blind, a link rod which has a partially-circular link, and a transmission rod. The actuator has an eccentric pin parallel to its axis of rotation which engages in the partially-circular link of the link rod, and the linear movement of the link rod is transmitted to the coupling rod of the at least second blind.

Abstract: A method for operating a motor vehicle having a camera device that records the area ahead of the vehicle and an associated control device for evaluating images taken by the camera device, wherein the control device evaluates the images in order to detect at least one hand gesture performed by a person shown in the images, wherein, when a hand motion describing a calling gesture that indicates a stop request is detected, in the case of a self-driving motor vehicle, the motor vehicle is controlled to stop in the vicinity of the person, or in the case of a non-self-driving motor vehicle, the driver of the motor vehicle is given a signal indicating the stop request.

Abstract: An arrangement consisting of a motor vehicle, including a battery, a charging connection and a charging device connected between the battery and the charging connection, and a connector. A first coupling which is or can be connected to the charging connection of the motor vehicle, and a second coupling which is connectable to an energy sink for power transport from the motor vehicle to the energy sink. The connector is designed for providing at least one item of power transport information to the motor vehicle. The charging device is designed for evaluating the item of power transport information or one of the items of power transport information and for specifying the direction of the power transport between the battery and the charging connection depending on the result of the evaluation.

Abstract: A method for preparing a vehicle for at least one future drive. The vehicle has at least one electric energy storage unit, with which at least one electric machine is supplied with electric energy. The vehicle is assigned to a system, which has at least one electric charging station and at least one station for provided services. The vehicle is further assigned to the at least one station for provided services, with which at least one provided service is made available. The at least one electric energy storage unit is connected to the at least one electric charging station when the at least one provided service is made available, and, through the at least one electric charging station, is supplied with electric energy.

Abstract: A method for operating a charging device for a battery of a motor vehicle. The charging device converts electric power obtained from a motor vehicle-external, three-phase energy system supplying other consumers in an infrastructure unit, in particular a house, by a converter device into an electric current that is suitable for charging the battery, and supplies electric energy of the battery by the converter device into the energy system. The charging device receives in an operating phase phase-resolved power data, which is fed to the energy system and measured by a measuring device, and determines phase-specified target power while using phase-related power data outputs for each phase. The target power that is determined for each phase is retrieved from each phase.

Abstract: This invention relates to a closing device for a housing of an air filter that can be closed with a housing cover. The assembly process is to be simplified and accelerated, while the number of parts required is to be reduced at the same time. According to the invention, this is achieved in that the housing cover and the housing can be connected to one another by means of a locking frame which surrounds the housing cover and the housing in the region of the housing edge, said locking frame being positionable in closed position by means of translatory motion, in which position it presses the housing cover onto the housing edge.
