| 20110228442 | CAPACITOR HAVING HIGH TEMPERATURE STABILITY, HIGH DIELECTRIC CONSTANT, LOW DIELECTRIC LOSS, AND LOW LEAKAGE CURRENT - Examples of the present invention include high electric energy density polymer film capacitors with high dielectric constant, low dielectric dissipation tangent, and low leakage current in a broad temperature range. More particularly, examples include a polymer film capacitor in which the dielectric layer comprise a copolymer of a first monomer (such as tetrafluoroethylene) and a second polar monomer. The second monomer component may be selected from vinylidene fluoride, trifluoroethylene or their mixtures, and optionally other monomers may be included to adjust the mechanical performance. The capacitors can be made by winding metallized films, plain films with metal foils, or hybrid construction where the films comprise the new compositions. The capacitors can be used in DC bus capacitors and energy storage capacitors in pulsed power systems. | 09-22-2011 |
| 20110038625 | ELECTROMECHANICAL POLYMER ACTUATORS - An adaptive lens comprises an actuator and a lens, the lens being mechanically coupled to the actuator so that energization of the actuator adjusts a focal point of the lens. The actuator may comprise a multilayer stack of electromechanical polymer (EMP) layers, having electrodes configured to apply an electric field across each EMP layer. The actuator may be operable to move and/or deform a lens, so as to adjust the focus properties of the lens. In some examples, the actuator has an annular shape, supporting a lens within the inner radius of the annulus. The lens position may be adjusted in an axial direction. In other examples, the actuator may be mechanically coupled a surface of a deformable lens, either directly or through another element of a lens structure. A strain applied to the lens modifies a curved surface of the lens, hence modifying the focal length of the lens. | 02-17-2011 |
