摘要： The invention provides a method and apparatus for positioning a surface (30) in a desired orientation. There is provided a movable member (10) supported for movement by a fixed member (40) and the movable member has an optical element, e.g. a flat mirror (30) fixedly attached thereto. In one embodiment the mirror scans a radiation beam incident thereon along a single axis. In a second embodiment, the radiation beam is scanned in two mutually perpendicular axes. A magnetic element (50) having a north and a south magnetic pole is fixedly attached to the movable member (10). A magnetically permeable stator element (70), that is stationary with respect to the movable member (10) and the magnetic element (50), is placed in the field of the magnetic element (50) such that the stator element (70) and said magnetic element (50) mutually generate a magnetic traction force between them. A current coil (60) is wound around a portion of the stator element (70) and a current driver (400) is provided for driving a current in the current coil (60). The current induces an electromagnetic field in the stator element (70) and an electromagnetic force acts on the magnetic element (50) for controlling movement of the surface (30) with respect to the fixed element (40). A radiation beam source (502) may be directed onto the movable mirror surface (30) and scanned by the movement of the mirror to direct the radiation beam in a desired propagation direction.

摘要： An output filter for a switching audio amplifier includes a magnetic core having a gapped central leg and a first and a second outer leg. The central leg and the first outer leg form a first independent magnetic path and the central leg and the second outer leg form a second independent magnetic path. The first and the second outer leg together form a joint magnetic path. A first coil having a first plurality of turns is wound around the first outer leg. A first load current applied to the first coil generates a first magnetic flux in a first direction through the joint magnetic path. A second coil having second plurality of turns is wound around the second outer leg. A second load current applied to the second coil generates a second magnetic flux in a second direction opposite to the first direction through the joint magnetic path.
