  • Publication number: 20140148800
    Abstract: Lens epithelial cells are destroyed and further growth is inhibited coincidental with eye surgery such as cataract surgery by heating the cells to a temperature above normal to thereby destroy the cells and inhibit future growth. The cells are heated by placement of a thermally conductive ring within the lens capsule and heating the ring thereby raising the temperature of lens epithelial cells adjacent to the ring.

  • Patent number: 8709791
    Abstract: A biosensor combining the sensitivity of surface acoustic waves (SAW) generated at a frequency of 325 MHz with the specificity provided by antibodies and other ligands for the detection of viral agents. In a preferred embodiment, a lithium tantalate based SAW transducer with silicon dioxide waveguide sensor platform featuring three test and one reference delay lines was used to adsorb antibodies directed against Coxsackie virus B4 or the negative-stranded category A bioagent Sin Nombre virus (SNV). Rapid detection of increasing concentrations of viral particles was linear over a range of order of magnitude for both viruses, and the sensor's selectivity for its target was not compromised by the presence of confounding Herpes Simplex virus type 1 The biosensor was able to delect SNV at doses lower than the load of virus typically found in a human patient suffering from hantavirus cardiopulmonary syndrome (HCPS).

  • Patent number: 8497874
    Abstract: Various technologies and techniques are disclosed for improving output rendering in anti-aliased rendering scenarios. The system receives information regarding at least one visual element area which is important for symmetric appearance. The information can include at least one coordinate of a guideline that a client would like to be snapped towards a pixel grid. The system uses the information to perform a pixel snapping procedure to snap the points of visual element to a pixel grid to create an adjusted image. The adjusted image is rendered on a display device in an anti-aliased rendering scenario. APIs are provided for setting horizontal and vertical pixel snapping guidelines. The collections containing the snapping guidelines are accessed and used during the pixel snapping procedure.

  • Patent number: 7924285
    Abstract: Described is a system and method by which text elements to be rendered on a computer display (e.g., paragraph, line or any subset of text including a character or glyph) may be individually or collectively animated, at an author-selected level of granularity. Animation of text may be specified by setting animation properties via direct coding (e.g., in markup) or by specifying animation code to execute on text-related data, just prior to rendering. The text to animate may be static, or dynamically obtained at runtime from an external source. The text to animate is maintained as a whole with other text of the same element, in a text object, until a processing level that produces separate glyph runs, with an animation transform associated with each glyph run to be animated. Also described is an API that supports text animation.
