Abstract
Rotational angle sensor systems and methods are provided for detecting an angular position of a movable structure. The movable structure may be configured to rotate about an axis of rotation between a first rotational position and a second rotational position. 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 a rotational position of the movable structure. Additionally, a first one of the magnet and the angle sensor is configured to rotate about the axis of rotation relative to a second one of the magnet and the angle sensor that is rotationally fixed such that the magnetic field orientation changes relative to the angle sensor as the movable structure rotates about the axis of rotation.
