Abstract
A position sensor arrangement that can determine the two-dimensional position of a variety of different movable devices, such as an electronic joystick. According to one embodiment, the position sensor arrangement includes two pair of magnetic sensing elements that are angularly offset or skewed with respect to one another in order to provide redundancy and accuracy with a minimum number of sensing elements.
Claims19
A position sensor arrangement, comprising:
- a first pair of sensing elements that sense the two-dimensional position of a movable device relative to a first sensing grid;
- and
- a second pair of sensing elements that sense the two-dimensional position of the movable device relative to a second sensing grid, wherein the first and second sensing grids are offset with respect to one another.
A position sensor arrangement, comprising:
- one or more movable sensor component(s) mounted to an electronic joystick;
- and
- first and second stationary sensor components mounted to a circuit board so that they are proximate the movable sensor component(s), wherein the first and second stationary sensor components are skewed on the circuit board with respect to one another.
