Abstract: The invention relates to a sensor apparatus, comprising: at least one ferromagnetic element, which, in an operating state, can be arranged on a torque transmission apparatus; and a measuring apparatus, which has at least one measuring element. Each measuring element is configured to measure a ferromagnetic resonance frequency of at least one ferromagnetic element. The measuring apparatus is configured to determine a torque of the torque transmission apparatus on the basis of so a shift in the measured ferromagnetic resonance frequency. The invention further relates to a method for determining a torque of a torque transmission apparatus.

Abstract: A device for attenuating reflections of an electromagnetic wave impinging thereon and a method of making the device. The device includes a structured film comprised of at least one of a ferromagnetic and ferrimagnetic material. The structured film has a structure and a uniform film portion of the at least one of a ferromagnetic and ferrimagnetic material underneath the structure such that the structured film has at least two different resonance frequencies.

Abstract: A film and method of preparing a film. The film is made of at least one of ferromagnetic and ferrimagnetic material. An elongated slot is included in the material and is operable to control the domain structure of the material. The depth of the elongated slot is the same as the thickness of the film and the width of the elongated slot is greater than an exchange length of the material. The slot is free from contact with any side of the film.

Abstract: In an I-conductor for the high-frequency or microwave systems, two uniform cores are disposed parallel to each other with a gap therebetween and a coil is disposed on each core in such a way that, when energized by an HF current, a magnetic circuit through the two cores is generated by way of the gap at one end of the arrangement. The magnetic field forming windings are uniform. As cores, magnetically anisotropic materials may be used.

Abstract: A clutch disk includes a hub area and a plurality of friction lining elements, which are supported on the hub area and arranged in sequence in the circumferential direction relative to a clutch disk rotational axis (A). These elements provide at least part of an associated friction surface area, where the friction lining elements are intended to make frictional contact with an associated opposing friction surface of a flywheel, a pressure plate, or the like. At least one friction lining element is supported so that the pressure exerted by its friction surface area against an opposing friction surface can change in response to a change in the sliding frictional interaction between its friction surface area and an opposing friction surface area which is or can be associated with it.

Abstract: A bridge coupling on a hydrodynamic torque converter is embodied with an axially movable piston arranged on a radial bearing. In one operating position, the piston can be brought into active connection with a support surface of a radial flange of the converter housing via at least one friction lining. The piston executes its axial movement under the influence of an axially elastic element integrated in the radial bearing and having an elastomer substantially deformable in the axial direction.
