Nasal dilator with means to direct resilient properties
ActiveUS8062329B2Great delaminating tendencyReduce forceRespiratorsBreathing masksNasal passageNasal passages
A nasal dilator comprises a laminate of vertical layers each consisting of one or more members or components. The laminated layers form a unitary, or single body, truss featuring horizontal regions adapted to engage outer wall tissues of first and second nasal passages and to traverse the bridge of a nose therebetween. When in use the dilator acts to stabilize and / or expand the nasal outer wall tissues and prevent said tissues from drawing inward during breathing. The dilator includes means to direct its resilient properties comprising one or more interior or exterior material separations, or discontinuity of shape of material, formed in at least one region of the truss and extending through at least one layer of the dilator. Said material separation or discontinuity of shape may comprise an opening, relief cut, slit or notch, and which may be configured to separate or vertically protrude, in part, from the truss when the dilator is in use on the nose of a wearer. Said separation or vertical protrusion changes the angle of focused delaminating spring biasing forces generated by the resilient layer, transforming said forces, at least in part, from primarily peel forces into primarily shear forces, and further redistributing or imparting said transformed forces to tissue engaging surface areas extending outward and beyond said material separation.

Laser-processed substrate for molecular diagnostics
ActiveUS20090279085A1Facilitate SERS analysisMaterial nanotechnologyRadiation pyrometryChemical reactionPhotonics
Surface enhanced Raman Scattering (SERS) and related modalities offer greatly enhanced sensitivity and selectivity for detection of molecular species through the excitation of plasmon modes and their coupling to molecular vibrational modes. One of the chief obstacles to widespread application is the availability of suitable nanostructured materials that exhibit strong enhancement of Raman scattering, are inexpensive to fabricate, and are reproducible. I describe nanostructured surfaces for SERS and other photonic sensing that use semiconductor and metal surfaces fabricated using femtosecond laser processing. A noble metal film (e.g., silver or gold) is evaporated onto the resulting nanostructured surfaces for use as a substrate for SERS. These surfaces are inexpensive to produce and can have their statistical properties precisely tailored by varying the laser processing. Surfaces can be readily micropatterned and both stochastic and self-organized structures can be fabricated. This material has application to a variety of genomic, proteomic, and biosensing applications including label free applications including binding detection. Using this material, monolithic or arrayed substrates can be designed. Substrates for cell culture and microlabs incorporating microfluidics and electrochemical processing can be fabricated as well. Laser processing can be used to form channels in the substrate or a material sandwiched onto it in order to introduce reagents and drive chemical reactions. The substrate can be fabricated so application of an electric potential enables separation of materials by electrophoresis or electro-osmosis.

Advanced clustering method for material separation in dual energy ct
ActiveUS20100328313A1Reconstruction from projectionDrawing from basic elementsDecompositionData domain
Three or more materials are advantageously separated from dual energy data by using a material separation technique. To effectively separate material clusters, a density plot is introduced to automatically render cluster separations. Initially, the projection data optionally undergo data-domain dual energy decomposition. Then, the image data is plotted in a vector plot whose axes are the low HU values and the high HU values. For a given data point in the vector plot, a number of data points is counted within in a region of interest surrounding the given data point to generate a density plot where each point now represents a density level surrounding the data point. Thus, clustering of a certain material is visualized by a predetermined color assignment scheme. Furthermore, special image processing methods such as Gaussian decomposition are used to improve the accuracy of material separation. In addition, the HSL color model may be used for better visualization and to bring a new dimension in material separation display.
