  • Patent number: 9556067
    Abstract: Certain example embodiments relate to Ni-inclusive ternary alloy being provided as a barrier layer for protecting an IR reflecting layer comprising silver or the like. The provision of a barrier layer comprising nickel, chromium, and/or molybdenum and/or oxides thereof may improve corrosion resistance, as well as chemical and mechanical durability. In certain examples, more than one barrier layer may be used on at least one side of the layer comprising silver. In still further examples, a NixCryMoz-based layer may be used as the functional layer, rather than or in addition to as a barrier layer, in a coating.

  • Patent number: 9499437
    Abstract: A coated article is provided so as to include a low-E (low emissivity) coating having an infrared (IR) reflecting layer(s) of or including a material such as silver (Ag), which is provided between a pair of contact layers. The low-E coating includes an overcoat having at least one layer of or including zirconium oxide and/or a substantially metallic layer. The overcoat has been found to improve the durability of the coating without significantly sacrificing desired optical characteristics. Such coated articles may be used in the context of windows.

  • Publication number: 20160265328
    Abstract: A process for altering a wettability characteristic of a carbonate formation to stimulate oil production includes selecting an oil bearing carbonate formation, injecting a silicide dispersion into the carbonate formation, and reacting the injected silicide dispersion with water. The reaction alters the wettability characteristic of the carbonate formation toward water wettability. The silicide dispersion can include an alkali metal silicide, such as sodium silicide. The reaction generates hydrogen, silicate, and heat that pressurizes the carbonate formation with the generated hydrogen, heats the carbonate formation with the generated heat, and reduces the viscosity of the hydrocarbons in the carbonate formation with the generated silicate. The reaction re-mineralizes the surfaces in the carbonate formation and alters the wettability characteristics of the carbonate formation as a calcium-silicon phase is formed. The hydrocarbons are recovered from the carbonate formation with a production well.

  • Publication number: 20160245060
    Abstract: Methods of stimulating enhanced oil recovery from a post-cold heavy oil production with sand (“CHOPS”) oil-bearing formation are disclosed. The invention relates to a method of stimulating oil recovery from a post-cold heavy oil production with sand (CHOPS) oil-bearing formation. The method optionally flushes a wellbore in a post-CHOPS oil-bearing formation having at least one worm hole to expel water from the wellbore and near wellbore region; then injects a alkali metal silicide into the post-oil-bearing formation via a wellbore to introduce the alkali metal silicide into at least one worm hole within the post-oil-bearing formation. The injection step is followed by reacting the injected alkali metal silicide to stimulate oil flow within the post-CHOPS oil-bearing formation; and recovering oil from the post-CHOPS oil-bearing formation. The alkali metal silicide dispersion can also be injected into the formation in a cyclic mode of alternating injection, soak, and production periods.

  • Patent number: 9365450
    Abstract: Low emissivity coated panels can be fabricated using a base layer having a low refractive index layer on a high refractive index layer. The low refractive index layer can have refractive index less than 1.5, and can include MgF2, CaF2, SiO2, or BO. The high refractive index layer can have refractive index greater than 2.3, and can include TiOx, NbOx, or BiOx. The multilayer base structure can allow color tuning with enhanced transmission, for example, as compared to similar structures having single layer base layer.

  • Patent number: 9355303
    Abstract: Face recognition using multilayered discriminant analysis includes systems and methods applying an initial linear discriminate analysis to a database of face images in a more-or less conventional manner. Initial fuzzy logic then is applied to the results of the initial linear discriminate analysis to produce a subset of the database of face images. Thereafter, a subsequent linear discriminate analysis is applied to the subset of the database of face images and subsequent fuzzy logic is applied to the results of the subsequent linear discriminate analysis to produce a further subset of the subset of the database of face images. The application of the subsequent linear discriminate analysis and application of the subsequent fuzzy logic may be repeated until the further subset contains only one, or zero, face images.

  • Patent number: 9321676
    Abstract: A bi-layer seed layer can exhibit good seed property for an infrared reflective layer, together with improved thermal stability. The bi-layer seed layer can include a thin zinc oxide layer having a desired crystallographic orientation for a silver infrared reflective layer disposed on a bottom layer having a desired thermal stability. The thermal stable layer can include aluminum, magnesium, or bismuth doped tin oxide (AlSnO, MgSnO, or BiSnO), which can have better thermal stability than zinc oxide but poorer lattice matching for serving as a seed layer template for silver (111).

  • Patent number: 9309149
    Abstract: Disclosed herein are systems, methods, and apparatus for forming a low emissivity panel. In various embodiments, a partially fabricated panel may be provided. The partially fabricated panel may include a substrate, a reflective layer formed over the substrate, and a top dielectric layer formed over the reflective layer such that the reflective layer is formed between the substrate and the top dielectric layer. The top dielectric layer may include tin having an oxidation state of +4. An interface layer may be formed over the top dielectric layer. A top diffusion layer may be formed over the interface layer. The top diffusion layer may be formed in a nitrogen plasma environment. The interface layer may substantially prevent nitrogen from the nitrogen plasma environment from reaching the top dielectric layer and changing the oxidation state of tin included in the top dielectric layer.

  • Patent number: 9296651
    Abstract: A transparent dielectric composition comprising tin, oxygen and one of aluminum or magnesium with preferably higher than 15% by weight of aluminum or magnesium offers improved thermal stability over tin oxide with respect to appearance and optical properties under high temperature processes. For example, upon a heat treatment at temperatures higher than 500 C, changes in color and index of refraction of the present transparent dielectric composition are noticeably less than those of tin oxide films of comparable thickness. The transparent dielectric composition can be used in high transmittance, low emissivity coated panels, providing thermal stability so that there are no significant changes in the coating optical and structural properties, such as visible transmission, IR reflectance, microscopic morphological properties, color appearance, and haze characteristics, of the as-coated and heated treated products.
