  • Patent number: 8330870
    Abstract: A method for improving image contrast for a display apparatus obtains a frame of image data having one or more code values for each pixel in the frame of image data, analyzes the frame of image data to identify a distribution of dark regions therein. The method further adjusts at least one of the one or more code values for the frame of image data according to the distribution of dark regions in the frame of image data and attenuates a brightness level available for the image frame according to the distribution of dark regions in the frame of image data.

  • Patent number: 8328720
    Abstract: A method of determining a prothrombin time is disclosed. A mediator is applied to a stratum corneum. The stratum corneum is penetrated to allow the mediator to enter a region containing interstitial fluid and interact with at least one capillary, causing blood and/or blood components to leak from the at least one capillary into the region containing interstitial fluid. A characteristic affected by the blood and/or blood components is measured in the region containing interstitial fluid which correlates to the prothrombin time. A system for measuring prothrombin time is also disclosed. The system has a mediator, one or more microneedles, and a processor directly or indirectly coupled to the one or more microneedles and configured to determine a coagulation change in blood or blood components in a region around the one or more microneedles after the one or more microneedles penetrate a stratum corneum.

  • Patent number: 8194178
    Abstract: A microshutter array has a frame having a light transmissive portion. Linear microshutter elements extend across the light transmissive portion and in parallel to each other. Each microshutter element has a flat blade extended in a length direction and first and second torsion arms extending outwards from each side of the blade in the length direction, the blade extending across the light transmissive portion. A control circuit provides a separately-controlled and independent voltage that is applied to each of the linear microshutter elements. A controller sets the respective voltages applied to each of the linear microshutter elements.

  • Patent number: 8134591
    Abstract: A method for forming a stereoscopic image forms separate left-eye and right-eye images in a repeated cycle that forms the left-eye image by providing data for lines of the left-eye image, ordered in sequence from a first to a second edge of an image frame, then forms successive lines of modulated light according to the ordered sequence by progressively scanning lines of modulated light across a display surface by rotating a scanning element forward from a first to a second position. The right-eye image is formed by providing data for lines of the right-eye image, ordered in sequence from the second to the first edge of the image frame and forming successive lines of modulated light, progressively scanning the lines of modulated light across the display surface by rotating the scanning element in reverse from the second to the first position. The left-eye image is distinguished from the right-eye image.
