Abstract: In some embodiments, an image sensor structure includes a super-pixel sensor comprising a plurality of micro-pixel sensors. The image sensor structure includes a plurality of micro-lenses affixed to focus light on the plurality of micro-pixel sensors. In some embodiments, each micro-lens of the plurality of micro-lenses directs light to locations on a respective one or more of the plurality of micro-pixel sensors. In some embodiments, the image sensor structure includes one or more color filters affixed at locations for filtering light directed by the micro-lenses to a first set of color image micro-pixel sensors comprising one or more of the plurality of micro-pixel sensors for capturing color image data and one or more polarization filters affixed at locations for filtering light directed by the micro-lenses to a second set of polarization micro-pixel sensors comprising one or more of the plurality of micro-pixel sensors for capturing depth map data.

Abstract: Some embodiments include a fixed chassis structure and a moveable carriage body carrying one or more lenses. The fixed chassis structure includes a magnetic friction track. The moveable carriage body carries one or more lenses. An electrically-controllable magnet is mounted to the moveable carriage body for generating a magnetic attraction force between the magnet and the magnetic friction track. The moveable carriage body is movably mounted to the chassis to allow movement along an optical axis through the one or more lenses. An inertial actuator is mounted to the moveable carriage body in an alignment such that the axis of motion of the actuator is parallel to the optical axis through the one or more lenses. The moveable carriage body is held in place with respect to the at least one allowed degree of freedom by one or more friction forces resulting from the magnetic attraction force.

Abstract: In some embodiments, a plurality of expected values of a drive current corresponding to respective ones of a plurality of potential values of a Hall sensor output is determined. An actual value of the Hall sensor output is measured. An actual value of the drive current is measured. A potential value of the Hall sensor output corresponding to the actual value of the Hall sensor output is selected. The expected value of the drive current associated with the selected potential value of the Hall sensor output is compared to the actual value of the drive current. A value of the drive current is adjusted to reduce a difference between the expected value of the drive current associated with the selected potential value of the Hall sensor output to the actual value of the drive current.
