  • Patent number: 9228716
    Abstract: A fiber-based reflective lighting device and a housed lighting device. The fiber-based reflective lighting device which includes a source configured to generate a primary light, and a substrate having a nanocomposite mat of reflective fibers having a diameter less than 1,000 nm which diffusively reflects light upon illumination with at least the primary light. The nanocomposite mat includes a reflectance-enhancing coating conformally disposed around an outer surface of the fibers, having a refractive index different from the reflective fibers, and which increases a reflectance of the substrate in the visible spectrum. The lighting device includes a light exit configured to emanate the reflected light. The housed lighting device includes a housing, a source configured to generate primary light and direct the primary light into the housing, the reflective nanocomposite mat of reflective fibers, and a light exit in the housing configured to emanate the reflected light from the housing.

  • 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.

  • Publication number: 20030223111
    Abstract: A sample analysis device is provided, the device comprising a frame adapted to accept at least one analysis apparatus, with each analysis apparatus having an analysis distance associated therewith. A eucentric goniometer is operably engaged with the frame and is adapted to eucentrically support a sample at a eucentric point within a reference system defined by the eucentric goniometer. The reference system of the eucentric goniometer is independent of the analysis distance. An axial adjustment device is operably engaged with at least one of the frame and the eucentric goniometer and is configured to coincidentally position the eucentric point and the analysis distance for the respective analysis apparatus. An associated device and method are also provided.

  • Patent number: 6520649
    Abstract: An image projection device adapted to project an image on a remotely disposed display is provided. The image projection device comprises a plurality of image elements, each image element being configured to emit an image portion therefrom. The image portions are directed through a projection lens, configured to cooperate with the image elements, and projected onto the remote display. A plurality of fiber-optic elements, corresponding to the plurality of image elements, is disposed between the image elements and the projection lens. Each fiber-optic element is configured to have a light-emitting end, toward the projection lens, tapering to a light-receiving end toward the corresponding image element. The fiber-optic element is thereby configured to receive the image portion from the image element at the light-receiving end and to expand the image portion before emitting the expanded image portion from the light-emitting end.
