The light emitted from LEDs is received by the first surface, further reflected by the second surface, and then sent out through the third surface to form a diffusion light and to show the status of the computer.Type: GrantFiled: May 10, 2001Date of Patent: May 28, 2002Assignee: ASUSTek Computer Inc.Inventor: Shih-Ping Yeh

Patent number: 6204832Abstract: A point source array generates an array of output beams defining a plurality of image pixels. A microlens array receives the output beams and direct them toward desired pixel locations. Either one or both of the point source array and microlens array are scanned over time to form an image of pixels. An image is composed of an array of image portions. Each image portion includes a plurality of pixels. For each image portion, there is a corresponding point source of light and a corresponding microlens. The corresponding point source and microlens scan light within the area of the image portion to generate all of the pixels for such image portion. The microlens array is an integral array. Each lens moves together with each image portion being scanned concurrently by the microlens array an point source array.Type: GrantFiled: May 4, 1998Date of Patent: March 20, 2001Assignee: University of WashingtonInventors: Charles D. Melville, Michael Tidwell, Richard S. Johnston

Patent number: 6195016Abstract: A fiber optic display sign has an optical system with enhanced light efficiency so that the display system is suitable for outdoor use. A number of fiber optics have light receiving ends arranged in a compact bundle for receiving an image from an image generator, the fiber optics coupling the image to the output ends thereof for display. An array of lenses is positioned adjacent the output ends of the fiber optics for directing or aiming the light from the fiber optics to control the viewing angle of the image displayed. The array of lenses may be fixed with respect to the output ends of the fiber optics or the lens array may be movable with respect thereto so as to vary the viewing angle. The image generator employs a light source formed of a densely packed array of white light emitting diodes to provide enhanced brightness.Type: GrantFiled: August 27, 1999Date of Patent: February 27, 2001Assignee: Advance Display Technologies, Inc.Inventors: Matthew W. Shankle, Gregory L. Heacock, Steven J. Shankle

Patent number: 6175679Abstract: An optical keyboard includes an optical panel having optical waveguides stacked together. First ends of the waveguides define an inlet face, and opposite ends thereof define a screen. A projector transmits a light beam outbound through the waveguides for display on the screen as a keyboard image. A light sensor is optically aligned with the inlet face for sensing an inbound light beam channeled through the waveguides from the screen upon covering one key of the keyboard image.Type: GrantFiled: July 2, 1999Date of Patent: January 16, 2001Assignee: Brookhaven Science AssociatesInventors: James T. Veligdan, John D. Feichtner, Thomas E. Phillips
