Abstract: This invention relates to an integrated sub-assembly for installation of a steering column and/or steering wheel of an automatic vehicle. A plurality of building units arranged in the area of the steering column and/or steering wheel are integrated with each other in terms of space for purpose of simplified manufacture and assembly so that, in this way, it is possible to economize on housing walls as well as on mechanical and electrical interfaces. Advantageous further developments deal with the drive of components within the building units by the steering wheel.

Abstract: The invention pertains to an angle of rotation sensor, wherein a magnet that is arranged such that it can be turned relative to a sensor that is sensitive to magnetic fields is coupled with a rotatable body, the angle of rotation (&agr;) of which needs to be measured. The invention aims to significantly broaden the measuring range of such an angle of rotation sensor. The invention proposes to utilize an asymmetric magnetic field such that the maximum and the minimum of the magnetic field measured by the probe are spaced apart by an angular range in excess of 270°. Advantageous additional developments pertain to other options for adapting the magnetic field to the desired shape. These options include an air gap that changes over the angle of rotation and the utilization of asymmetric pole shoes.

Abstract: The invention relates to a method and apparatus for providing a casing for a sensor which is to be thin-walled in places. The principle of the invention is to align the sensor circuit precisely and completely seal it in plastic using separately actuatable support devices and a slowly curing plastic.

Abstract: The present invention relates to a transducer with a piezoelectric crystal for parking aids in automotive vehicles. Such transducers must be sealed against steam jets. This object is achieved by the present invention by means of a plug including projections forming an evacuatable chamber in conjunction with the inner wall of a housing bowl. Developments of the present invention relate to the protection and sealing of the diaphragm retainer, which is part of the transducer, against moisture and mechanical displacement due to vibrations and other environmental influences.

Abstract: In order to improve a proximity switch insensitive to interference fields r detecting the position of a machine element with at least one sensor which generates in the proximity of a machine element standing in a position to be detected a total signal having a detection field signal component caused by the machine element and an interference field signal component caused by the interference field and transmits it to a circuit which converts the total signal into an output signal, such that both the gradients of the detection field generated by the machine element and the gradients of the interference field do not affect response of the proximity switch, it is suggested that the conversion of the total signal into the output signal be carried out by the time dependence of the interference field being determined, by a corresponding sequence of scanning pulses being obtained therefrom and the first signal being scanned with these, and by a value which is determined thereby resulting in an output signal indicatin
