  • Patent number: 11929447
    Abstract: A method for annealing an absorber layer is disclosed, the method including contacting a surface of the absorber layer with an annealing material provided as a gel. The annealing material comprises cadmium chloride and a thickening agent. A viscosity of the gel of the annealing material is greater than or equal to 5 millipascal seconds.
    Type: Grant

  • Patent number: 8145016
    Abstract: A system whereby a potential advertiser can see a motorist's view of an outdoor ad space without the need to actually drive past the outdoor ad space. A video image is recorded of the outdoor ad space from a vehicle driving past the outdoor ad space using a video recorder. A database is populated with images of each outdoor ad space. An advertiser queries the database using some identifier in order to retrieve the image and once retrieved, view the image.

  • Publication number: 20070172578
    Abstract: A method has been discovered to produce a resistant starch product that retains the same cooking quality as found in untreated rice starch or flour, but has a higher percentage of starch resistant to ?-amylase digestion. This method uses a debranching enzyme, e.g., pullulanase, to digest the starch, but does not require pre-treating the starch source prior to enzymatic treatment. This method produced resistant starch from low amylose starches, rice starch (24%) and rice flour (20%). Surprisingly the resistant starch product formed by this method retained the pasting characteristics of the untreated flour or starch, and was heat stable. This method may also be used to produce resistant starch from other botanical sources, e.g., corn, wheat, potato, oat, barley, tapioca, sago, and arrowroot. Resistant starch produced by this method has a variety of uses in food products.

  • Publication number: 20070142678
    Abstract: An efficient method is disclosed for extracting lutein from corn, sweet potato, and other plant products, and for extracting aflatoxin-free lutein from aflatoxin-contaminated plant grains and other plant products safely without any toxic by-products. The lutein is extracted using acetone, and either chilled or saponified to separate from the lipids. If contaminated with aflatoxin, the extracted aflatoxin-contaminated lutein is treated with lipoxidase. This method may be used in producing aflatoxin-free lutein from other contaminated grains or plant oils, or other plant products, including corn, cotton, soybean, rice, barley, wheat, maize, millet, and peanut.
