Abstract: The invention relates to a system formed of several IMUs (1, 2, 3, 4, 5) having at least one slave IMU (1, 2, 3, 4) that is configured to record and transmit data. A master IMU (5) having an analysis computing unit is additionally provided which is configured to record data itself and to receive data from the at least one slave IMU (1, 2, 3, 4) and to jointly analyse the data for a calculation of a kinematic chain and to transmit the analysed data to an electronic control device of a machine connected with the system.

Abstract: An axial piston pump having several pistons has a magnetic encoder (5), which is arranged on a swash plate, and a magnetic field sensor, which is arranged in such a way that it faces towards the magnetic encoder (5). The magnetic encoder (5) has at least two permanent magnets (2, 3) and a plate (4) which consists of a ferromagnetic material. The permanent magnets (2, 3) are arranged on the plate (4) in such a way that they each faces a magnetic pole towards the plate (4), and this pole is at least partially covered by the plate (4) in each case.

Abstract: An actuating system for a valve which can be used as a control valve. The valve system having an outer housing, a receiving region for a switching spindle of the valve, at least one inductive sensor running in parallel to the receiving region, and at least one substantially circular cylindrical position encorder.

Abstract: A switch includes a button which is connected to a ring-shaped permanent magnet that is magnetized along a z-axis, a guide member made from an non-ferromagnetic material inside which the button and the ring-shaped permanent magnet are arranged so as to be moveable along the z-axis, as well as at least one sensor that has a sensitive area that is arranged inside the ring-shaped permanent magnet and that is configured to measure a change in a magnetic field in the radial direction within a x-y-plane, wherein the x-axis and the y-axis lie orthogonally to the z-axis, respectively.
