20090073108 | High Efficiency Display Utilizing Simultaneous Color Intelligent Backlighting and Luminescence Controllling Shutters - A display comprises a front-end component having a matrix of neutral light valves that defines the resolution of the display. A backlight unit provides backlighting for the front-end component and has a plurality of individual elements grouped into repeat units, wherein the individual elements in the repeat units differ in color and the repeat units have a resolution less than the display resolution. All individual elements in individual repeat units are capable of simultaneously emitting light incident on more than one neutral light valve. | 03-19-2009 |
20090108729 | Magnetic Field Compensation Apparatus for Cathode Ray Tube - A cathode ray tube (CRT) having a glass envelope is disclosed. The glass envelope is formed of a rectangular faceplate panel and a tubular neck connected thereto by a funnel. An electron gun is positioned in the neck for directing electron beams toward the faceplate panel. A yoke is positioned in the neighborhood of the funnel-to-neck junction. The yoke has windings configured to apply a horizontal deflection yoke field and a vertical deflection yoke field to the beams. At least one magnetic field sensor is located near the glass envelope for sensing an ambient magnetic field environment of the CRT. A controller receives a signal from the magnetic field sensor. Register correction coils are mounted in the vicinity of the neck and are dynamically controlled by the controller to shift the beams. Quadrupole coils are applied to the neck and have adjacent poles of alternating polarity such that the resultant magnetic field being dynamically controlled by the controller based on the magnetic field sensor signal moves outer ones of the beams to correct the misconvergence caused by the register correction. | 04-30-2009 |
20090120488 | Luminescent solar concentrator devices - A relatively large field of laminated fluorescent square LSC tiles are interdigitated by long thin bi-facial silicon photovoltaic cells. The laminated fluorescent LSC tiles each comprise a thick clear substrate bonded to a fluorescent dye film with a mirror backing and a protective layer. Incident sunlight is received by the clear substrate's face, and the dye converts that to fluorescent light. The resulting fluorescent light can only escape out the perimeter edges of the clear substrate where the photovoltaic cells are positioned. Each silicon photovoltaic cell receives fluorescent light laterally from the adjacent and opposite edges of the two fluorescent LSC tiles it separates. The collection area of the face of each fluorescent LSC tile is very large compared to the areas of the edges, and so highly concentrated light is provided to relatively small area photovoltaic cells for conversion to electricity. | 05-14-2009 |
