    Abstract: A throttle drive actuator for an engine includes a first magnet including a north pole and a south pole and a second magnet positioned adjacent the first magnet, the second magnet including a north pole and a south pole. The north pole of the second magnet is positioned opposite the south pole of the first magnet to create a first magnetic field, and the south pole of the second magnet is positioned opposite the north pole of the first magnet to create a second magnetic field. A direction of the second magnetic field is directed opposite a direction of the first magnetic field. An armature is positioned between the first magnet and the second magnet, the armature including windings. The armature rotates between the first magnet and the second magnet when the windings are energized, and the armature rotates a valve of a throttle body of the engine, to open a close an air passage of the throttle body.

    Abstract: This magnetic voice-coil shutter drive actuation system for an optical shutter having an aperture with at least one shutter blade includes an actuator operating to open/close the shutter blade when moved in opposing directions, and a moveable element that operates said actuator and can be a moveable voice coil or a moveable permanent magnet. The voice coil is activatable to generate an electromagnetic flux in opposing polar orientations to react against the magnetic flux produced by the permanent magnet. The moveable element can be located in a position peripheral of the aperture and not surrounding the aperture, or in a position peripheral of the aperture and surrounding the aperture. The magnetic flux produced by the permanent magnet and the electromagnetic flux produced by the voice coil define magnetic axes that are parallel to each other and to a central axis for the aperture.
