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.
