20090162004 | OPTICAL PRINTED CIRCUIT BOARD AND MANUFACTURING METHOD - The invention provides a method of manufacturing an optical printed circuit board and an optical printed circuit board. The method comprises providing a support layer; on the support layer, providing an optical core layer; forming optical channels from the optical core layer and surrounding the optical channels with cladding thereby forming optical waveguides; and during said step of forming the optical channels, forming one or more alignment features, e.g. projections, on the optical printed circuit board. | 06-25-2009 |
20100290737 | OPTICAL WAVELENGTH DIVISION MULTIPLEXED MULTIPLEXER/DEMULTIPLEXER FOR AN OPTICAL PRINTED CIRCUIT BOARD AND A METHOD OF MANUFACTURING THE SAME - The invention provides an optical mux/demux for an optical printed circuit board. The mux/demux comprises: a first waveguide formed on a support layer for carrying a wavelength division multiplexed optical signal; a separator/combiner for separating the wavelength division multiplexed signal into component signals of corresponding wavelengths or for combining component signals into the said wavelength division multiplexed signal; and plural second waveguides, each for receiving or providing one or more of the said component signals, wherein the separator/combiner is at a predetermined location relative to the waveguides. | 11-18-2010 |
20100309688 | LIGHT COLLIMATING LIGHTGUIDE - A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A lightguide receives the light from an edge surface and guides the light by total internal reflection. The lightguide also has features that exist on one or more lightguide surfaces in the shape of a triangular wedge that reduces the range of angles in the vertical direction within the lightguide. This arrangement enables improved angular performance from out-coupled light. | 12-09-2010 |
20110051035 | UNIFORM DIFFRACTIVE BACKLIGHT - A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A light guide receives the light from an edge surface and guides the light by total internal reflection. The light is extracted from the lightguide using sub-wavelength extraction features designed on the basis of one grating structure with a second interlinks structure cut into the first structure. The first structure determines the extraction properties. The second structure determines the extraction efficiency and uniformity of the system. Higher efficiency and more uniform sub-wavelength extraction are possible with a device in accordance with the invention. | 03-03-2011 |
20110051460 | BACKLIGHT - A backlight is provided for illuminating an at least partially transmissive display. The backlight includes a light source. A light guide receives the light from an edge surface and guides the light by total internal reflection. The light extracted from the lightguide has an angular emission profile such that when incident on a prism film, collimated light is produced. | 03-03-2011 |

20100205579 | Application Design And Data Flow Analysis - Techniques, apparatuses, and systems for application design and application data flow analysis. Techniques, apparatuses, and systems can include providing a design interface to create an application with different user groups and access rights, the design interface operable to specify an action to include to a page of the application, where the action, when invoked, modifies the application state; receiving an action specification that describes an access rights modification that results from an invocation of the action during an execution of the application, where the access rights modification indicates an enabling or disabling of one or more access rights of a user; and generating application specification queries and commands to enforce access rights based on the access rights modification. | 08-12-2010 |
20100223268 | Searching Digital Information and Databases - This application describes methods for searching digital information such as digital documents (e.g., web pages) and computer databases, and specific search techniques such as authority ranking and information retrieval (IR) relevance ranking in keyword searches. In some implementations, the technique includes analyzing digital information viewed as a labeled graph, including nodes and edges, based on a flow of authority among the nodes along the edges, the flow of authority being derived at least in part from different authority transfer rates assigned to the edges based on edge type schema information. In some implementations, the system includes an object rank module configured to generate multiple initial rankings corresponding to multiple query keywords, each of the multiple initial rankings indicating authority of nodes in a graph with respect to each respective query keyword individually; and a query module configured to combine the multiple initial rankings in response to a query. | 09-02-2010 |
20110191407 | WEB APPLICATION DEVELOPMENT FRAMEWORK - Techniques, systems, apparatus and computer-program products are disclosed for developing a web-hosted shared database system with improved user interface and reduced programming. In one aspect, using a web application development framework includes declaratively specifying a web application's pages using page configurations. The framework can automatically coordinate page state with the state of a database server and an applications server, so that the specified page is first rendered and then one or more portions of the page can be updated in response to a server data change, Also, programs that are executed when a request is issued are declaratively specified using program configurations. Either or both of the page configurations and the program configurations can be implemented by access to a unified application state virtual database. Further, the unified application state virtual database can include the persistent database of the application and transient memory-based data, such as session and page data. | 08-04-2011 |
