摘要： An apparatus and method control the shape of a structure with one or more surfaces and internal actuators. A plurality of translational actuators are capable of extending and contracting. The structure can have any number of controllable surfaces, including one. The shapes of the surfaces are controlled by computing the actuator strokes or loads required for achieving specified surface deflections. There are two methods for accomplishing this control. In the actuator stroke-control method, the surface deflections, or deflection errors for closed-loop control, are multiplied by a stroke-control gain matrix which is a function of the properties of the structure with the actuators absent. In the actuator load-control method, the surface deflections, or deflection errors for closed-loop control, are multiplied by a load-control gain matrix which is a function of the properties of the structure with the actuators absent. The control gain matrices minimize the surface shape errors. Ratios of stresses to allowable values are continuously monitored throughout the structure and corrective action is taken to prevent an overstressed condition.

摘要： The present invention is directed to a piezoelectric transformer based power converter that exhibits efficient operating point tracking ability while providing output regulation by means of simultaneous two-parameter control of the converter power stage. A regulation control stage provides the power stage a regulation control signal indicative of the difference between the measured output parameter and a set-point reference, therefore continuously controlling the gain of the converter to result in a stabilized, regulated output. Additionally, a frequency control stage simultaneously provides the power stage with a frequency control signal correlative to the difference between the current and desired operating points of the piezoelectric transformer. The power stage then translates the frequency control signal into an adjustment to the operational frequency of the input signal to the piezoelectric transformer, as to continuously drive the operating point to the desired position.

摘要： A thin nearly wireless adaptive optical device capable of dynamically modulating the shape of a mirror in real time to compensate for atmospheric distortions and/or variations along an optical material is provided. The device includes an optical layer, a substrate, at least one electronic circuit layer with nearly wireless architecture, an array of actuators, power electronic switches, a reactive force element, and a digital controller. Actuators are aligned so that each axis of expansion and contraction intersects both substrate and reactive force element. Electronics layer with nearly wireless architecture, power electronic switches, and digital controller are provided within a thin-film substrate. The size and weight of the adaptive optical device is solely dominated by the size of the actuator elements rather than by the power distribution system.

摘要： An isolator mount for the active dissipation of shocks and vibrations is presented. The invention includes at least one energy dissipating layer and deflectable elements so as to provide soft damping for small disturbance excitations, yet remaining sufficiently stiff to mitigate large shocks. The mount transfers mechanical energy to the dissipating layers via the device structure. Dissipating layers convert shock and vibration energies to either heat or magnetic energy.

摘要： An isolator mount capable of dissipating shocks and vibrations is presented. The present invention includes a mount which is load bearing and capable of withstanding repeated deflections and strains, at least two damping layers composed of an energy damping viscoelastic polymer, and at least two constraining layers composed of an energy damping alloy. Each layer of energy damping viscoelastic polymer is separately disposed and bonded to the exterior of the mount. One constraining layer is bonded to and substantially covers each damping layer. Damping and constraining layers minimize the stiffness change to the mount.
