  • Publication number: 20120099478
    Abstract: The invention provides a method and device for auto-generating GOOSE signal connection topology from substation level based on IEC61850 standard. The method comprises the following steps: import substation configuration language (SCL) file; search all GOOSE input and output signals under each access point; match the output signals to the input signals; and generate GOOSE signal connection topology based on the result of said matching. The device comprises an importing module for importing substation configuration language file; a GOOSE signal analyzer for searching all of GOOSE input and output signals under each access point, and matching said GOOSE output signals to said GOOSE input signals; and topology data module for generating GOOSE signal connection topology based on said matching. The device comprises a storage module. The storage module comprises an input dataset for storing GOOSE input signals and an output dataset for storing GOOSE output signals and their matching input signals.

  • Patent number: 6492096
    Abstract: A patterned molecular self-assembly is provided. The patterned molecular self-assembly comprises a support having an exposed patterned surface and a non-patterned surface. A compound is selectively adsorbed on the exposed patterned surface. The compound may comprise a first compound selectively adsorbed on the exposed patterned surface and a second compound selectively adsorbed on the first compound to form at least one bilayer. The patterned molecular self-assembly may further comprise a first set of bilayers and a second set of bilayers wherein the first set of bilayers has a different composition than the second set of bilayers.

  • Patent number: 6447887
    Abstract: An electrostatic self-assembly method of fabricating electrostrictive and piezoelectric thin film assemblies not only provides a thinner film than is attainable by conventional methods, but provides excellent molecular-level uniformity and precise structural control, and thus large, effective piezoelectric coefficients. The method produces a thin film assembly including (a) a substrate, and (b) a film having one or a plurality of layers disposed upon the substrate, wherein at least one of the layers includes a dipolar material, and this layer of dipolar material has a uniform thickness of at most 500 nm.

  • Patent number: 6357910
    Abstract: A pyrometer for measuring the temperature of an object with high accuracy and fast response time that uses both multi-wavelength pyrometry techniques and nanotechnology. Radiance from an object is transmitted through a fiber optic cable, is received by a thin-film multi-wavelength modulator, and is detected by an optical detector array. More specifically, the pyrometer includes means for conveying light; an optical lens; an optical fiber; means for optically modulating the wavelength of light; means for optically detecting the modulated light; means for transforming the optically detected wavelengths into electrical signals; and means for processing and recording the electrical signals. The means for optically modulating the wavelength includes at least one piezoelectric film deposited by an electrostatic self-assembly method.

  • Patent number: 6316084
    Abstract: Abrasion and scratch protective coatings magnetic coatings, electrically and thermally conducting coatings, and UV absorbing coatings are provided by electrostatic self-assembly (ESA) of one layer of an organic or polymer molecule and one layer of inorganic clusters in a layer by layer fashion at room temperature. A combination of inorganic clusters having a particle size of preferably less than 30 nm and flexible organic molecules allows fabrication of films tens to hundreds of micrometers thick, with large pores and excellent stress relaxation.
