A sensor device for determining a position of a magnetic source relative to the sensor device, or for determining an orientation of a uniform magnetic field relative to the sensor device, the sensor device comprising: a substrate comprising a plurality of magnetic sensors configured for providing a plurality of sensor signals; a signal combiner configured for combining the sensor signals into a combined waveform; a processing circuit configured for extracting said position or orientation from the combined waveform; wherein the signal combiner is configured for generating the combined waveform by including one or more portions of the sensor signals during respective predefined time durations, which time durations are determined during a calibration procedure, wherein at least two of said time durations have different values.

Device and system for determining a position of a magnetic source, or an orientation of a uniform magnetic field

The present disclosure describes a sensor system for measuring a process value of a physical system, including: a plurality of sensors, wherein each sensor is configured to generate a sense signal as a function of the process value at a given time; a system state corrector configured to determine an actual system state of the physical system at a given state update cycle; a system state predictor configured to determine a predicted system state of the physical system at a given prediction cycle from a previous system state at a previous state update cycle; a sense signal predictor configured to determine predicted sense signals at the given prediction cycle from the predicted system state by applying a first operation to the predicted system state using a sense signal model of the physical system for predicting the sense signals.

Sensor system and method for measuring a process value of a physical system

A sensor device for determining a position &#x3d5;of a rotor of an electrical machine, for example an electric motor or electric generator. The sensor device comprises a number r of sensors, which detect the magnetic field generated by the rotor and/or a permanent magnet rotating with the rotor, and an electronic circuit which is configured The invention further concerns a control device for an electric motor with such a sensor device.

Sensor device for determining the position of the rotor of an electrical machine and control device for an electric motor

The invention concerns a method for determining a position &#x3d5; of a position indicator of a position measuring system, in which the sensor signals ato aof a number of r sensors are recorded as a signal vector {right arrow over (a)}=(a, . . . , a), a measurement vector {right arrow over (q)} is formed according to {right arrow over (q)}=g({right arrow over (a)}), a 2-component vector {right arrow over (p)} is calculated according to {right arrow over (p)}=M&#xb7;{right arrow over (q)}, wherein M is a 2&#xd7;n matrix, and the position &#x3d5; is determined by means of a predetermined function &#x192;({right arrow over (p)}) to &#x3d5;=&#x192;({right arrow over (p)}), wherein the function &#x192;({right arrow over (p)})=&#x192;(p,p) is based on the equations p=cos(&#x3d5;) and p=sin(&#x3d5;). The matrix M is determined in a calibration phase in such a manner, that the transformation {right arrow over (p)}=M&#xb7;{right arrow over (q)} is a linear mapping, which maps a number m of measurement vectors {right arrow over (q)}on 2-component vectors {right arrow over (p)}, wherein the tips of the vectors {right arrow over (p)}substantially lie on a circle or on a circular arc. The method allows the elimination of external fields.

System for determining the position of the position indicator of a position measuring system

The disclosure relates to a multiaxial force-torque sensor having a transducer structure, with strain gauges placed in defined areas to measure the strain, from which the forces and torques are calculated, and where the transducer structure can include (e.g., consist of) two concentric rings connected with spokes. The transducer structure can be a planar mechanical structure, and all strain gauges can be applied to the same surface of the transducer structure to measure non-radial strain components.
