A position sensor device for determining a two-dimensional position of a magnet which is movable in a plane, and that generates a magnetic field; the position sensor device includes: a semiconductor substrate having a plurality of magnetic sensors configured for determining three orthogonal magnetic field components (Bx, By, Bz) at a single location. The semiconductor substrate further includes a processing circuit configured for determining the two-dimensional position (R,θ; X,Y) based on the three orthogonal magnetic field components. A thumbstick assembly has such a position device. A method is provided for determining the two-dimensional position.

Device, method and system for determining position of a magnet

A weight sensor comprises a sensing system including a target piece and a sensing element, configured to provide changes of a magnetic field, being generated by motion of the target piece. The sensing element senses these changes and provides a signal representative of the position of the target piece. An integrated circuit with processing means can process signals from the sensing element. The flexible piece receives a force stimulus, so that upon exerting a force on the flexible piece by a product due to the weight of said product, the displacement of the target piece with respect to sensing elements can be sensed.

Force sensing scale with target

A magnetic sensor system includes a magnet and a sensor device. The magnet has a shape and is movable along an axis between a first position and a second position and is optionally also rotatable about this axis. The magnetic sensor device has a plurality of magnetic sensitive elements for measuring at least two orthogonal magnetic field components or at least two orthogonal magnetic field gradients, and a processing circuit for determining an axial position of the magnet or whether the magnet is located in the first or second position based on the first and second magnetic field components or gradients, and optionally also for estimating or calculating an angular position of the magnet. A method of determining the axial and/or angular position. A magnetic sensor device includes features of the magnetic sensor system.
