Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: A device for operating an active roll stabilization system of a vehicle is described, which active roll stabilization system has a roll stabilizer on at least one axle of the vehicle, which roll stabilizer is configured to adjust, by use of an electrically operated actuator, a degree of twist between lever arms of the roll stabilizer which act on different sides of the axle, in order to counteract a roll movement of the vehicle. The device is set up to determine which operating mode of a plurality of different operating modes of the roll stabilization system has been selected by a user of the vehicle. Further, the device is set up to operate the actuator as a generator, in order to recuperate electrical energy from a roll movement of the vehicle and/or from a roadway-induced movement of the vehicle, in a manner dependent on the selected operating mode.

Abstract: A method and a device for inductive radiofrequency welding of metal products, include heating by inducing radiofrequency currents with use of at least one induction conductor. The metal products and a welding zone are moved relative to one another, so that edge regions of the metal products to be welded are brought in contact in the welding zone and are welded together to form a weld seam. Metal products with different material thicknesses and/or material properties can be welded together because an induction conductor which heats the edge regions of the metal products is used which includes at least two mutually separable induction conductor components that are assigned to the respective metal product and are adapted thereto, and the edge regions to be welded are heated in a manner that is adjusted separately for the respective metal product.

Abstract: The concept underlying the invention is the development of a generic method for the detection and identification of gases in airplane interior spaces and an associated device, which is small and manageable, has a simple design, and allows the immediate and simultaneous detection and identification of the gases to be examined. This is achieved in that the supply air of the airplane interior space (20) is fed to a measuring device (1) and the measurement results of the measuring device (1) are analyzed by means of mathematical methods. Such methods and the associated devices for the detection and identification of gases in airplane interior spaces are used in order to spot and verify gases, particularly odors and explosive gases and/or gases harmful to people's health.

Abstract: A motor vehicle body can be manufactured economically and assembled without any problem from prefabricated modules. This is resolved in that the modules are connected to one another in a non-detachable manner in a joint zone, such that a sheet of the one module coming into contact in the joint zone on a sheet section of another module, are joined to one another in a joining process, in which at least one of the sheet sections has been cold-formed, with positive and/or non-positive fit, and in that in at least one of the modules an access channel is formed, extending at least in sections along the joint zone and accessible from outside for introduction of a joining tool.

Abstract: The invention relates to an adapter, which in a simple manner enables secure connection of two components (A1, A2, A3, A4, T1, T2, T3, T4) manufactured from different materials. This is achieved according to the invention in that the adapter has a basic element (5, 6, 7, 8) which is manufactured from a material which belongs to the group of materials to which the material of the first component (A1, A2, A3, A4) is allocated, and a connection element (10, 19, 24, 25, 28, 29) indissolubly connected by a joint operation positively and non-positively to the basic element (5, 6, 7, 8), said connection element being manufactured from a material which belongs to the group of materials to which the material of the second component (T1, T2, T3, T4) is allocated. In addition to this, the invention relates to a component produced using an adapter according to the invention.
