  • Patent number: 7495638
    Abstract: This invention provides a continuous display with non-uniform pixel density, forming a foveated display. A single, continuous display has a higher pixel density at the center of the display than at the periphery of the display. Where two continuous displays are used in accordance with the present invention, the central forward gaze of the viewer's image will be displayed in high resolution while the leftmost portion of the left eye display will be in low resolution and the rightmost portion of the right eye display will be in low resolution. The pixel resolution of the visual display may correspond to the visual acuity of the human eye. A foveated image display system using a continuous display with non-uniform pixel density increases the field of view while reducing the image bandwidth.

  • Patent number: 6797620
    Abstract: A method and apparatus is provided for filling apertures formed in a substrate surface by depositing materials that selectively inhibit or limit the formation or growth of subsequent layers used to fill an aperture. In one aspect, a method is provided for processing a substrate including providing a substrate having a field and apertures formed therein, wherein the apertures each have a bottom and sidewalls, depositing a seed layer on the bottom and sidewalls of the apertures, depositing a growth-inhibiting layer on at least one of the field of the substrate or an upper portion of the sidewalls of the apertures, and depositing a conductive layer on the growth-inhibiting layer and the seed layer. Deposition of the growth-inhibiting layer improves fill of the aperture from the bottom of the aperture up to the field of the substrate.

  • Patent number: 6169359
    Abstract: The luminance of a phosphor suitable for an alternating current thin-film electroluminescent device is substantially improved according to the present invention by including an alkali halide. The alkali halide included within the bulk of the phosphor material results in providing a significant number of trapping states which trap free electrons within the phosphor material. The addition of the trapping states (added defects) within the bulk tend to control the electrical and optical characteristics of the phosphor material. This reduces asymmetric light output characteristics of traditional phosphor material, reduces asymmetric current movement within the phosphor material, and decreases the influence of the interfaces between the phosphor material and insulating materials resulting in decreased aging and increased brightness.

  • Patent number: 4305634
    Abstract: The electrical plug guard comprises a disc member having a pair of elongated slots to frictionally receive the prongs of an electrical plug. The slots have centers offset with respect to each other along the length of the slots. The slots are effective to skew the prongs of the plug with respect to each other when the prongs are inserted in slots through the disc member. The disc member has a thickness sufficient to prevent finger contact with the prongs which are electrically active when partially inserted into an electrical plug outlet.
