Abstract: A corner part for a wiper panel assembly for a ground vehicle, the corner part comprising an outside panel, having an outside face and an inside face both extending substantially parallel to an upward direction of the corner part; and a drain, having an outlet opening at the outside face, an inlet located at the inside face and opening at the inside face in the upward direction, and a channel, connecting the inlet to the outlet.

Abstract: A vehicle comprising means for attaching a cargo transporting member thereto, wherein the vehicle further comprises a wind deflector for deflecting wind from the cargo transporting member when being attached to the vehicle, wherein the wind deflector comprises two or more wind deflector portions which are configured to deflect wind when the vehicle is travelling in a travelling direction, wherein the wind deflector is configured to be expanded into at least a first wind deflecting state and collapsed into a collapsed state, wherein the two or more wind deflector portions are configured to be pivoted relative each other with respect to a common rotational axis so that the wind deflector is expanded and collapsed between the first wind deflecting state and the collapsed state.

Abstract: A system and method for adjusting an air deflector on a roof of a truck cabin to an optimal position when the truck is connected to a trailer, where the system comprises an air deflector, an electric actuator, and an electronic control unit, where the system further comprises a handheld device provided with stored information of different truck types and a table for different truck-trailer combinations, where the handheld device is adapted to determine a value corresponding to the height of the trailer and a value corresponding to the distance between the truck and the trailer, to determine a set value for the actuator based on the values and the stored information, and to send the set value to the electronic control unit, where the electronic control unit is adapted to set the air deflector in an optimal position by adjusting the actuator in dependency of the set value.

Abstract: A wind deflector arrangement includes a wind deflector configured to reduce air resistance, the wind deflector being arranged on a cab roof of a vehicle, the wind deflector being pivotable around a substantially transversal axis of the vehicle, wherein the wind deflector arrangement further includes at least one air pressure sensor for measuring an air pressure during traveling of the vehicle, wherein the at least one air pressure sensor is arranged within a space formed by the wind deflector and the cab roof of the vehicle. A method for controlling a wind deflector arrangement and a vehicle including such a wind deflector arrangement are also provided.

Abstract: A flow field plate for a bipolar plate or bipolar plate assembly of a fuel cell or a fuel cell stack has an electrode facing front side, a backside and at least a cooling fluid manifold for supplying cooling fluid to the flow field plate. The backside includes a cooling fluid flow field for substantially uniformly distributing the cooling fluid over the flow field plate. The flow field plate further includes a cooling fluid sub-manifold which is adapted to provide cooling fluid from the cooling fluid manifold to a cooling fluid flow field. The cooling fluid sub-manifold is fluidly disconnected from the cooling fluid flow field, a bipolar plate or bipolar plate assembly including a flow field plate, as well as a fuel cell or fuel cell stack including such a flow field plate and/or bipolar plate or such a bipolar plate assembly.

Abstract: An arrangement and method are provided for optimizing a position of at least one air deflector guiding an airflow around the vehicle such as a truck or truck-trailer combination during driving. A position of the at least one air deflector is determined by an actuator which is controlled in response to a sensed control signal indicating the air resistance of the vehicle, the speed of the vehicle is controlled by a vehicle driving control system for providing a constant speed of the vehicle during the optimization, and the position of the at least one air deflector is varied until the control signal indicates a minimized air resistance of the vehicle.
