A sensor system may include a magnet arranged such that a linear position of the magnet corresponds to a position of a trigger element on a substantially linear trajectory, and such that an angular position of the magnet corresponds to a selected position of a selection element, the selected position being one of a plurality of selected positions. The sensor system may include a magnetic sensor to determine the position of the trigger element based on a strength of a first magnetic field component and a strength of a second magnetic field component, and determine the selected position of the selection element based on a strength of a third magnetic field component and the strength of the second magnetic field component. The first magnetic field component, the second magnetic field component, and the third magnetic field component may be perpendicular to each other.

Contactless magnetic sensing trigger system

A sensor arrangement includes a ring magnet linearly displaceable along its vertical axis of the ring magnet and including an outer ring section of a first pole pair, an inner ring section of a second pole pair. At least one magnetic sensor circuitry is positioned a non-centered offset distance apart from the ring magnet in a plane perpendicular to the ring magnet's vertical axis. The at least one magnetic sensor can generate spatial magnetic data produced by linear displacement of the ring magnet. A computing unit coupled to the at least one magnetic sensor circuitry and configured to obtain the spatial magnetic data and to determine amount of displacement of the ring magnet after a linear displacement of the ring magnet based on the obtained spatial magnetic data.

Systems, devices, and methods for magnetic position sensing

A control stick may include a magnet and a three-dimensional (3D) magnetic sensor. The 3D magnetic sensor may determine a twist angle of a handle of the control stick based on a strength of a magnetic field at the 3D magnetic sensor. A twisting of the handle may modify an air gap between the 3D magnetic sensor and the magnet. The strength of the magnetic field may be based on strengths of first, second, and third magnetic field components. The 3D magnetic sensor may determine a tilt angle of the handle based on a ratio of the strength of the first magnetic field component to the strength of the third magnetic field component. A tilting of the handle in a direction corresponding to the first magnetic field component may modify the ratio of the strength of the first magnetic field component to the strength of the third magnetic field component.
