摘要： A displacement amplifier receives an actuation displacement signal from a piezoelectric actuator. The displacement signal is amplified by one or more stages of compliant elements, and a corresponding force is applied to a load. Wide frequency response is achieved in response to the resilience characteristics of the compliant elements that are formed from any of several materials, illustratively aluminum, steel, titanium, plastics, composites, etc., and are produced by any of several manufacturing techniques, illustratively extrusion, die casting, forging, etc. The compliant elements can be configured as plural compliant mechanical displacement amplifier stages. In bilateral arrangements displacement signals from distal ends of the motive source are applied to symmetrical, or mirror image, arrangements of compliant elements. The motive source, which may be a piezoelectric actuator, delivers its displacement signal at one end thereof to one or more compliant elements. The other end of the piezoelectric actuator can be grounded.

A membrane is arranged to overlie the array, and a control point is affixed to the array and optionally to the membrane that overlies the array. The membrane is formed of a compliant material or fabric. A further array is arranged in some applications at a predetermined orientation with respect to the first array. The arrays have respective actuation force response characteristics to achieve contour upon the application of actuation forces.

摘要： A wind turbine has a longitudinal airfoil blade that exerts a torque on the generator in response to an impinging air current. A compliant airfoil edge arrangement is disposed along an edge of the airfoil blade for at least a portion of a longitudinal dimension of the airfoil blade. A morphing drive arrangement varies a configuration of the compliant airfoil edge arrangement and consequently the aerodynamic characteristics of the airfoil blade. A drive arrangement applies actuation forces to the upper and lower compliant surfaces via the upper and lower actuation elements. The compliant airfoil edge is arranged as a trailing edge of the airfoil blade.

摘要： An arrangement for orienting a device angularly is provided with a back element on which the device to be oriented is installed. A ball and a spherical gear are arranged concentrically. A base portion has a socket that engages with the ball. Also, a motor having a rotatory shaft is installed on the base portion, and a worm drive element is coupled to the rotatory shaft and arranged to engage the spherical gear when the ball and socket are engaged, whereby the spherical gear is urged along the longitudinal axis of the tapered worm drive element and the tapered worm drive element slides along the gear teeth of the spherical gear. The motor enhances the rigidity of the base portion. The worm drive element and the spherical gear disengage in response to the application of a force through the first spherical gear.
