Abstract: A switching device for a transmission of a motor vehicle includes an unsynchronized claw switching element that has a first switching part and a second switching part which are rotatable relative to each other around an axis of rotation. The first switching part has a first switching gearing and the second switching part has a second switching gearing which are displaceable relative to each other along the axis of rotation between a coupled position and an uncoupled position. Rotation positions in which the first and second switching parts are rotated relative to each other are detectable by a detection device. An electronic computing device moves the first and second switching parts from the uncoupled position into the coupled position depending on detected rotation positions. The detection device has a sensor element and a transmitter element, with transmitter segments, fixedly connected to the second switching part.

Abstract: A magnetic detector includes a detecting section having a surface facing a magnetic body which moves and emits a magnetic flux. The detecting section includes plural magnetic sensors for detecting the magnetic flux. The magnetic sensors are arranged in a matrix form having three or more rows and three or more columns arranged along the surface of the detecting section. The magnetic detector provides an input device precisely detecting a moving direction and a moving amount of the magnetic body.
Abstract: A rotary accelerometer having a nonrotatable cylindrical magnet return path formed out of magnetic permeable material. One or more permanent magnets, with two opposite poles, are disposed around the magnetic return path. An electrically conductive cup with an access for rotation therearound in which the cup surrounds the permanent magnets and the permanent magnets are arranged so as to produce a magnetic field through the cup into the nonrotatable cylindrical magnet return path, thereby inducing eddy currents inside the cup when rotating in the magnetic field. A stator core is formed out of magnetic permeable material surrounding the cup and nonrotatable relative thereto, the stator core having at least two pickup members. The stator is formed from at least one continuous piece of magnetic permeable material. One or more stator windings are disposed on to the pickup members of the stator core for sensing changes in a secondary magnetic field generated by the eddy currents in the cup.
