摘要： A linear motor system includes an element with a threaded passage, a threaded shaft, and a driving system. The threaded shaft has an axis of rotation which extends through and is at least partially engaged with at least a portion of the threaded passage. The driving system comprises at least two members operatively connected to the element. Each of the two members comprises two or more piezoelectric layers and electrodes which are coupled to opposing surfaces of each of the piezoelectric layers. The members are configured to expand and contract in a direction along the axis of rotation. The driving system is configured to subject the element to vibrations causing the threaded shaft to simultaneously rotate and translate in the direction along the axis of rotation through the element and apply an axial force in the direction along the axis of rotation.

摘要： A lens actuator module includes a lens assembly with an optical centerline and a clear aperture, a bearing guide integrated adjacent to the clear aperture with the centerline of motion substantially parallel to the optical centerline, a linear actuator with a preloaded frictional contact point that moves the lens along the centerline. The preload force is perpendicular to the optical centerline, constant and generated in-line with the contact point such that the preload force produces substantially zero additional friction in the bearing guide irrespective of the location along the optical centerline.

摘要： A driving system in accordance with embodiments of the present invention includes a structure and a vibration system. The structure has at least one point to frictional couple to and drive a movable element in one of at least two directions. The structure also has at least two bending modes which each have a different resonant frequency. The vibration system applies two or more vibration signals which are at a vibration frequency to each of the bending modes of the structure. The vibration frequency is substantially the same as one of the resonant frequencies. At the vibration frequency one of the bending modes of the structure is vibrating substantially at resonance and the other of the bending modes of the structure is vibrating at partial resonance. The vibration system adjusts a phase shift between the two or more applied vibration signals to control which one of the at least two directions the moveable element is moved.

摘要： A haptic actuator apparatus and a method of making the same include an ultrasonically vibrating motor and its housing. The housing includes a guide structure coupled to the ultrasonically vibrating motor and at least one spring. The guide structure defines at least one path of motion of the ultrasonically vibrating motor. The at least one spring delimits the at least one path and generates human-detectable vibrations in response to an impact with the ultrasonically vibrating motor.

摘要： Electromechanical translation apparatus provides power-off clamping because each clamp assembly comprises pressure means and clamp actuator means acting in opposition. The pressure means is arranged, when the actuator is de-energized, to apply clamping force to releasably clamp the associated movable member to the clamp assembly. The clamp actuator means is arranged, when energized, to act against the pressure means to release the movable member.
