Abstract: An apparatus includes a force bias element coupled to a plant in a vehicle. The force bias element has a first bandwidth. An active suspension includes a linear electromagnetic actuator located within an interior of the force bias element. The linear electromagnetic actuator has a second bandwidth that is higher than the first bandwidth and is coupled to the plant.

Abstract: A position sensing system includes a member movable along a path, the member having an elongated magnet extending along the path, the magnetic field orientation of the elongated magnet being at an angle with respect to the path. A sensor determines a position of the member along the path based on a measurement of a magnetic field generated by the elongated magnet.

Abstract: A position sensing system for positioning a linear motor that includes a stator and an armature having magnets, the armature moving relative to the stator along a path. A sensor determines a position of the armature based on measurements of a magnetic field generated by the magnets of the armature.

Abstract: A force producing element produces a force along a force axis between a plant and a support. Flexure pivots flexibly secure the force producing element to the plant and the support. The flexure pivots transmit the force between the plant and the support while isolating the force producing element from external forces.

Abstract: The upper voice coil motor magnet assembly (64a?) of a disk drive (10?) is magnetically aligned with the lower voice coil motor magnet assembly (64b?) using an alignment fixture (126). The alignment fixture (126) engages the upper voice coil motor magnet assembly (64a?) and lifts the same into a suspended position above the lower voice coil motor magnet assembly (64b?). In this suspended condition, the alignment fixture (126) allows the magnetic field to move the upper voice coil motor magnet assembly (64a?) within the horizontal dimension to a magnetically aligned position with the lower voice coil motor magnet assembly (64b?). Thereafter, the alignment fixture (126) lowers the upper voice coil motor magnet assembly (64a?) to a position where the same is again supported above the lower voice coil motor magnet assembly (64b?).
