Abstract
Rotational angle sensor systems and methods are provided for detecting an angular position of a movable structure. A system may include a movable structure, a rotating member, a magnet and an angular sensor. The movable structure may be configured to rotate about an axis of rotation between a first rotational position and a second rotational position. A rotating member may be coupled to the movable structure and configured to rotate about the axis of rotation based on movement of the movable structure such that rotational positions of the rotating member and the movable structure correspond to one another. A magnet may have a magnetic field pattern with a magnetic field orientation and an angle sensor may be configured to detect the magnetic field pattern and generate one or more signals, based on the magnetic field orientation, corresponding to the rotational position of the movable structure.
