20080230970 | Mount for Shock and Vibration Damping - 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. | 09-25-2008 |
20090027788 | Thin Nearly Wireless Adaptive Optical Device - 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.
