Abstract: An improved multi-die LED lighting apparatus for use with a lens that facilitates light dispersion while minimizing color banding and maintaining the light distribution intent of the design of the lens. The individual LED die are dithered, both rotationally and spatially relative to neighboring LED dies to minimize color banding of the LED lighting apparatus. The result is an reduction in color banding while seeking to retain the original light dispersion intent of the lens.

Abstract: Provided are a method, system, and program for replicating a file. A file is copied to a target storage file system stored as a base file. A reference file comprising the copied file is generated at a local storage. An update is applied to the file at the local storage. A delta file is generated indicating differences between the updated file at the local storage and the reference file. A file system command is used to transmit the delta file to the target storage file system store to store in a directory of the target storage file system, wherein the file in the local storage is replicated at the target storage by a combination of the base file and the delta file.

Abstract: A rotating beacon including a plurality of light emitting diodes and a plurality of reflectors is disclosed. The light emitting diodes are attached to one or more printed circuit boards mounted on a base.

Abstract: A display includes a screen having a first region of a color light emissive material and a second region of a monochrome material. In one embodiment, the color light emissive material is formed from triads of red, green and blue triads of subregions. A first set of emitters grouped in threes is aligned to the first region and a second set of emitters is aligned to the second region. The first set of emitters is driven by red, green, and blue components of a color image signal to produce a multicolor display. The second set of emitters is driven by a monochrome image signal to produce a monochrome display. In a display assembly according to the invention, the first and second sets of emitters are incorporated on a common substrate. The first set of emitters forms a fixed text subdisplay and the second set of emitters is arranged as a conventional matrix addressable array.

Abstract: A field-emission display includes a faceplate having an inner or outer surface covered by a depixellation film containing a large number of graded refractive index microlenses. The depixellation film averages or spreads the light illuminated by each pixel so that the illumination intensity is relatively constant across the surface of the pixel. As a result, the viewing characteristics of the field-emission display are improved.

Abstract: A backing plate for a transparent substrate constructed of two polarizer sheets. The axes of polarization of the polarizer sheets are substantially orthogonal to each other. The backing plate thus absorbs more than 98% of incident light and prevents substantial reflection. The backing plate is especially adapted for use with a transparent substrate undergoing any photolithographic process.

The mask layer is attached to a matrix defining the pixels in the screen and preferably includes voids formed therethrough corresponding to each pixel. The voids in the mask layer preferably have a size generally corresponding to that of the pixels near the phosphor material and narrow in the direction of the electron source.

Abstract: A driver circuit for driving the emitters of a flat panel display such as a field emission display. The driver circuit includes a capacitor and a charge circuit. The capacitor is connected between the emitter and an extraction grid held at a constant potential. The charge circuit has two inputs respectively connected to a row line and a column line. The charge circuit also has a charge terminal connected to the capacitor. In operation, the charge circuit applies at the charge terminal a selected voltage level which is below the grid voltage. The selected voltage level represents the intensity of the pixel associated with the emitter. In response to the selected voltage level at the charge terminal, the extraction grid charges the capacitor to a potential which is the difference between the grid voltage and the selected voltage level. When charged, the capacitor is isolated from the driver circuit. The charge stored in the isolated capacitor discharges through the emitter.
