A device for determining an encoder magnet rotation angle is provided, wherein the device includes an encoder magnet and a number of n greater than or equal to two magnet sensors. The magnetic field includes a plurality of plane-parallel magnetic field planes, wherein a surface normal of the plane-parallel magnetic field planes is parallel to an encoder magnet rotation axis. The magnetic field further includes a plurality of magnetic field vectors in the plane-parallel magnetic field planes. The two magnet sensors are in at least one of the plane-parallel magnetic field planes, wherein a first magnetic field vector has a first angle at a position of a first magnet sensor, and wherein a number n−1 of further ones of the magnet sensors are arranged at positions in the magnetic field whose magnetic field vectors have an angle which satisfies the equation wherein 1<i≤n.

Device and method for determining an encoder magnet rotation angle

An integrated circuit for controlling an electric motor, which has a primary component with a coil and a permanently magnetic secondary component cooperatively connected via an air gap to the primary component, has a semiconductor substrate in which are integrated a microcontroller and/or a pre-amplifier for controlling the coil of the electric motor. For detecting the position of the permanently magnetic secondary component, at least two magnetic field sensors with their measurement axes aligned crosswise relative to each other are integrated in the semiconductor substrate.

A triggering device for a safety device in an automotive vehicle, in particular for an airbag, has an electrical component that has at least one force sensor and that is attached to the body of the automotive vehicle in such a way that a measurement signal that is dependent on the deformation of the body can be applied at a measurement signal output of the force sensor. An evaluation device for processing the measurement signal is connected to the measurement signal output. The force sensor has at least one piezo element, which is integrated into a CMOS chip together with the evaluation device.

A network processor exchanges data of various descriptions via a plurality of network nodes with external network devices, such as other processors, controllers, transducers, or sensors. The network processor includes a master processor for control tasks of the processor, and a network coprocessor for supporting network tasks. A first and a second bus system, associated with the master processor and the network coprocessor with its associated functional units, particularly Data Link Layer memory devices, respectively, serves to separate the two fields of tasks from each other. This permits both a support of gateway functions and a support of Higher Layer functions. Higher Layer memory devices, whose messages are ultimately sent or received by the master processor, are accessible from the master processor or the network coprocessor directly or indirectly via the first and/or second bus systems.
