  • Patent number: 9027305
    Abstract: Disclosed are various structure surface configurations and related methods. An exemplary structure includes a facade that has grooved cavities that are configured in a manner that reflects summer (cooling season) insolation and absorbs winter (heating season) insolation. The effective absorptivities of the exemplary structure for various cavity reflectance characteristics, i.e., a wide range of diffuse and specular reflectance characteristics, are evaluated using a Monte Carlo model. The calculations in an illustrated embodiment are performed for the latitude of 41° N where both heating and cooling loads are significant. Embodiments of various structures are similarly within the scope of the disclosure for locations of different latitudes and longitudes.

  • Publication number: 20140004345
    Abstract: The present disclosure provides a stress micro mechanical system for measuring stress and strain in micro- and nano-fibers, tubes, and wires as well as for measuring the interface adhesion force and stress in nanofibers and nanotubes embedded in a polymer matrix. Also described are nanofibers comprising a cascade of surface ripples or periodic necks. Such surface features may be formed during cold drawing of electrospun nanofibers.

  • Patent number: 8608992
    Abstract: A method for producing one or more nanofibers includes providing (a) a solution comprising a polymer and a solvent, (b) a nozzle for ejecting the solution, and (c) a stationary collector disposed a distance d apart from the nozzle. A voltage is applied between the nozzle and the stationary collector, and a jet of the solution is ejected from the nozzle toward the stationary collector. An electric field intensity of between about 0.5 and about 2.0 kV/cm is maintained, where the electric field intensity is defined as a ratio of the voltage to the distance d. At least a portion of the solvent from the stream is evaporated, and one or more polymer nanofibers are deposited on the stationary collector as the stream impinges thereupon. Each polymer nanofiber has an average diameter of about 500 nm or less and may serve as a precursor for carbon fiber production.

  • Patent number: 8499645
    Abstract: The invention provides a stress micro mechanical system for measuring stress and strain in micro- and nano-fibers tubes, and wires as well as for measuring the interface adhesion force and stress in nanofibers and nanotubes embedded in a polymer matrix. A preferred system of the invention has a substrate for supporting a MEMS fabrication. The MEMS fabrication includes freestanding sample attachment points that are movable in a translation direction relative to one another when the substrate is moved and a sample is attached between the sample attachment points. An optical microscope images surfaces of the MEMS fabrication. Software conducts digital image correlation on obtained images to determine the movement of the surfaces at a resolution much greater than the hardware resolution of the optical microscope.

  • Patent number: 7788040
    Abstract: A system, for processing patient medical information for storage in an electronic patient medical record repository, includes an interface, a repository, and a data processor. The interface receives data representing genomic information of a patient. The repository includes a patient record incorporating data representing genomic information specific to a particular patient. A data processor compares the genomic information specific to a particular patient with the received genomic information. The data processor identifies a genomic match in response to the comparison and predetermined matching criteria. The data processor initiates processing of patient record information specific to the particular patient in response to an identified match.
