  • Patent number: 7341774
    Abstract: An electronic or opto-electronic device or a chemical sensor comprising: an interpenetrating network of a nanostructured high surface area to volume ratio film material and an organic/inorganic material forming a nanocomposite. The high surface area to volume film material is obtained onto an electrode substrate first, such that the nano-scale basic elements comprising this film material are embedded in a void matrix while having electrical connectivity with the electrode substrate. For example, the film material may comprise an array of nano-protrusions electrically connected to the electrode substrate and separated by a void matrix. The interpenetrating network is formed by introducing an appropriate organic/inorganic material into the void volume of the high surface area to volume film material. Further electrode(s) are defined onto the film or intra-void material to achieve a certain device.

  • Patent number: 7320816
    Abstract: A novel decorative structure includes a length of strand material, having a plurality of individual strands twisted with respect to one another and fixed with respect to one another near a first end of the strands, a twisting member having a plurality of apertures formed therein, each adapted to receive a respective one of the individual strands therethrough, and an anchoring member adapted to support the decorative structure on a support surface. In a particular embodiment the twisting member is a disc, such that when the twisting member is advanced from a second end of the strands to the first end, the strand material is caused to unwind. Similarly, when the twisting member is advanced from the first end to the second end of the strands, the strand material is caused to wind up. When unwound, the strands can support a container within the unwound ends of the strand material.

  • Patent number: 7314668
    Abstract: A heat treatable coated article (e.g., vehicle windshield, IG unit, etc.) is provided with a dual-silver low-E coating. Before and/or after heat treatment (HT), the coating and/or coated article has a visible transmittance of at least 70%, more preferably at least 75%. Moreover, the coating and/or coated article is designed so as to have approximately the same color when viewed over a wide range of viewing angles. In certain embodiments, at least one contact layer (e.g., of or including NiCrOx) that contacts an infrared (IR) reflecting layer (e.g., Ag) is oxidation graded so that it progressively becomes less oxidized through its thickness as it nears the IR reflecting layer. In still other embodiments, a Si-rich silicon nitride layer(s) may be utilized to reduce haze.

  • Patent number: 7314673
    Abstract: A cadmium oxide (CdO) film doped with any of the Group III elements is substantially transparent to radiation between about 0.7 ?m and 12 ?m. A film made according to the invention having a sheet resistance of <600?/? will also have exceptionally low optical absorption throughout the IR range. The film is suitably employed as transparent, electrically conductive electrodes, and can be used in devices such as liquid crystal cells for beam steering, spatial light modulators, optical switches for fiber optical communications, switchable and/or tunable polarization modification components, and top transparent electrodes for SWIR (1.3 and 1.5 ?m) VCSELs.
