Abstract: The invention relates to a housing (1), in particular for a control unit of a fan motor, having at least two housing elements (10, 30) and having a connecting element (50), wherein the housing elements (10, 30) interact with the connecting element (50), and wherein the brought-together housing elements (10, 30) form an interior region (5). According to the invention, a duct (40) is formed which, before and/or during the assembly of the housing (1), in particular before and/or during the bringing-together of the housing elements (10, 30), connects the interior region (5) and the surroundings of the housing (1) and permits a fluid flow between the interior region (5) and the surroundings, and which, upon the completion of the assembly process, is closed off by way of the interaction of at least one housing element (10, 30) and the connecting element (50).

Abstract: Inventory management system having a plurality of filling devices, which are to be filled with merchandise elements, a plurality of merchandise elements in and/or at the filling devices, detector devices, which are assigned to the filling devices and/or merchandise elements, and which are for detecting sensor data that are indicative of a fill state of at least some of the filling devices with the merchandise elements, and a control device that is configured to determine a current stock of at least some of the filling devices and/or of at least some of the merchandise elements, particularly in and/or at the filling devices, on the basis of the sensor data.

Abstract: A cooling system (1) for a fuel cell system (11), in particular for a vehicle, which comprises a fuel cell cooling circuit (10) for cooling the fuel cell system (11), and a battery cooling circuit (20) for cooling a battery (21), with an exchange of thermal energy between the fuel cell cooling circuit (10) and the battery cooling circuit (20).

Abstract: The invention relates to an electric drive (10, 12, 14, 16, 18) for a vehicle (1), in particular a motor vehicle. The electric drive (10, 12, 14, 16, 18) has an electric motor (10), wherein the electric motor (10) has at least one electric drive means (12, 14, 16) for producing a rotary movement. The electric drive (10, 12, 14, 16) also has a heating apparatus (20, 22, 25) which is operatively connected to the electric motor (10) and is designed to dissipate operating heat losses (34), which are produced by the electric motor (10) during production of the rotary movement, and to transfer them to a passenger compartment (26) of the vehicle (1).

Abstract: The present invention relates to a pulse valve (10) with a closing body (18) that cooperates with a valve seat (22) and, in a first switching position, establishes a flow connection between a supply channel (12) and a discharge channel (14) and, in a second switching position, blocks the flow connection. The closing body (18) periodically alternates between the two switching positions during the actuation of the pulse valve (10), its movement being hydraulically damped by a throttle point (70). It is provided that the hydraulic damping occurs only in a subrange of motion (62).
