Patent number: 7989072Abstract: A transparent conductive oxide (TCO) based film is formed on a substrate. The film may be formed by sputter-depositing, so as to include both a primary dopant (e.g., Al) and a co-dopant (e.g., Ag). The benefit of using the co-dopant in depositing the TCO inclusive film may be two-fold: (a) it may prevent or reduce self-compensation of the primary dopant by a more proper positioning of the Fermi level, and/or (b) it may promote declustering of the primary dopant, thereby freeing up space in the metal sublattice and permitting more primary dopant to create electrically active centers so as to improve conductivity of the film. Accordingly, the use of the co-dopant permits the primary dopant to be more effective in enhancing conductivity of the TCO inclusive film, without significantly sacrificing visible transmission characteristics. An example TCO in certain embodiments is ZnAlOx:Ag.Type: GrantFiled: October 23, 2009Date of Patent: August 2, 2011Assignee: Guardian Industries Corp.Inventors: Alexey Krasnov, Yiwei Lu

Publication number: 20090225426Abstract: A parabolic primary mirror (10) has a concave specular surface (12) that is constructed and positioned to receive solar energy and focus it towards a focal point. A secondary mirror (14) having a convex specular surface (16) is constructed and positioned to receive focused solar energy from the primary mirror and focus it onto an annular receiver (18). The annular receiver (18) may include an annular array of optical elements (100) constructed to receive solar energy from the secondary specular surface (14) and focus it onto a ring of discrete areas. A ring of solar-to-electrical conversion units are positioned on the ring of discrete areas.Type: ApplicationFiled: May 19, 2009Publication date: September 10, 2009Applicant: Edtek, Inc.Inventors: William E.

Patent number: 7560156Abstract: The present invention relates to a security element in the form of a strip. The strip exhibits optical effects which vary, depending on the illumination or viewing direction. The optical effects are provided only in one or more definably delimited, mutually spaced surface regions. The strip outside the visually variable surface regions is transparent or is adapted to the appearance of the surface of the substrate.Type: GrantFiled: April 25, 2003Date of Patent: July 14, 2009Assignee: Leonhard Kurz GmbH & Co. KGInventor: Werner Reinhart

Publication number: 20090153971Abstract: Optical multilayer thin-film filters (OMTFFs) are disclosed. An exemplary filter includes a transparent substrate, a multilayer film (MF) on a surface of the substrate, and a top layer. The MF is of alternatingly laminated layers of a high-refractive-index (HRI) material and a low-refractive-index (LRI) material. The top layer is on an uppermost layer of the MF and is of a material having atoms of lower atomic weight than atoms of either the HRI or LRI materials. The OMTFFs are made in a vacuum environment by alternatingly laminating respective thin films of the HRI and LRI materials on the substrate. The top layer is formed on the MF. Between forming the MF and top layer is a suppression step in which the newly formed MF is exposed to moisture by briefly venting the vacuum to atmosphere. The moisture inhibits migration of the low-molecular-weight atoms into the HRI and LRI materials.Type: ApplicationFiled: December 8, 2008Publication date: June 18, 2009Inventors: Motoo Takada, Shinya Kikegawa, Toshimasa Nishi, Hiroto Ishikawa

Publication number: 20090141357Abstract: The present invention relates to a plastic lens comprising a multilayer antireflective film and to a method for manufacturing the same. The plastic lens has a multilayer antireflective film present on the surface of a plastic lens substrate, either directly or through another layer. The multilayer antireflective film comprises a composite layer in which at least two metal oxide layers, containing an identical metal element but different quantities of oxygen, are adjacent. In the method for manufacturing the above plastic lens, each of the metal oxide layers constituting said composite layer is formed by employing a single vaporization source and by vapor depositing adjacent layers under differing conditions of partial pressure of reactive oxygen gas.Type: ApplicationFiled: November 25, 2008Publication date: June 4, 2009Applicant: HOYA CORPORATIONInventors: Hitoshi KAMURA, Yukihiro Takahashi, Hisao Kawai

Patent number: 7525730Abstract: Various embodiments of the invention relate to methods and systems for generating the color white in displays created from interferometric modulators and more specifically, to the generation of the color white through the use of reflected light at two wavelengths. In one embodiment, a display device displays the color white. The color white is generated by reflecting light from two pluralities of interferometric modulator types. The first modulator type reflects colored light at a specific wavelength. The second modulator type reflects colored light selected to be at a wavelength complementary to the first. The combined light reflected from the two types appears white in the display.Type: GrantFiled: July 22, 2005Date of Patent: April 28, 2009Assignee: IDC, LLCInventor: Philip D. Floyd
