  • Publication number: 20070051463
    Abstract: Stretchable material with recovery properties that are waterproof and conformable in two or three dimensions particularly adapted for flashing in structures, especially at the bottom and lower corners of openings where water is likely to collect. A method of installing flashing materials in openings in structures.

  • Patent number: 6355333
    Abstract: A construction membrane that resists liquid and air penetration, is moisture vapor permeable, and has integral drainage channels is provided. An exterior wall construction incorporating such barrier sheet material is also provided. The wall construction may be faced with stucco, siding, brick or stone. A method for bonding and texturing the construction membrane is also provided.

  • Patent number: 5414987
    Abstract: A process for treating a ply-twisted crimped multifilament yarn. The process involves adjusting the temperature and moisture content of the yarn prior to passing the yarn through a stuffer box which is essentially free of steam. Excess hot fluid is removed from the yarn, and the yarn's temperature is adjusted to a temperature in the range of about 40.degree. to 90.degree. C. before the yarn is passed through the stuffer box. The yarns may be used for making a textured saxony-type carpets having a tightly tailored surface texture.

  • Patent number: 5325301
    Abstract: The present invention relates broadly to a method of image analysis for analyzing the texture of a surface, and to a saxony-type carpet having a tightly tailored surface texture characterized by this method. The method employs a model based on a second order co-occurrence matrix model which calculates a set of textural parameters for image classification. This co-occurrence matrix model examines the statistics of the spatial relationship between gray levels in a homogeneously textured image with calculated textural features which represent measures such as homogeneity and contrast. The method of the present invention uses this model to construct a set of normalized textural parameters from the textural parameters and calculates a value for the normalized textural parameters from this set, where the normalized textural parameters are related to the physical properties of the surface, such as pile lay of a carpet.
