Abstract: When retrieving documents over a network, such as the Internet, the font size imposed by default or by a style sheet is sometimes not the right size for comfortable viewing by a user. A database of font size changes made by a user to particular documents is maintained and used to infer a font size preference for a document. A document is displayed using a recorded preference. If no preference is found for a document, a check is made to determine if a preference has been specified for a different document related to that document by having a common portion of a network address. That is, if a preference had been specified for one chapter of a document having a particular network address, a preference would be inferred for other chapters of the document based on a common portion of a hierarchical address.

Abstract: A method for automatically determining whether a browser supports scalable vector graphics (“SVG”). The method uses a two prong process to make a proper detection for various types of browsers. The method includes using JavaScript to detect Multipurpose Internet Mail Extensions (“MIME”) types from the browser to detect SVG support. If scanning of the MIME types detects that SVG support is present, the requested web page containing SVG content is sent. If no SVG support is detected, the non-SVG version of the web page is sent to the browser. If the browser does not return a list of MIME types, the method of Visual Basic Scripting Edition language (“VBScript”) to instruct the browser to create an SVG object on the client device. If the object is created, SVG support has been detected, and the browser is served the web page having SVG content.

Abstract: A method and computer graphics system capable of super-sampling and performing real-time convolution are disclosed. In one embodiment, the computer graphics system may comprise a graphics processor, a sample buffer, and a sample-to-pixel calculation unit. The graphics processor may be configured to generate a plurality of samples. The sample buffer, which is coupled to the graphics processor, may be configured to store the samples. The sample-to-pixel calculation unit is programmable to generate a first subset of pixels by filtering using the rendered samples and a second subset of the output pixels by interpolating using the first subset of pixels and/or the rendered samples. By interpolating a subset of the output pixels, the graphics system may be able to operate at higher resolutions and/or refresh rates since filtering of the samples is computationally intensive.

Abstract: A CPU executes program instructions which result in valid and invalid intermediate results. By selecting the desired intermediate results, a program is able to be successfully executed. Analysis of the intermediate results must avoid plausible wrong results. A programmable feature allows the instruction decoder to provide plural answers, including plausible wrong answers. Instruction output selection logic selects a predetermined buffer, and this permits further microprocessor operation with the correct intermediate result.

Abstract: One embodiment of the present invention provides a system for processing a request directed to a secondary storage system. The system operates by receiving the request at an interface of the secondary storage system. This request specifies an operation to be performed on the secondary storage system, a location within the secondary storage system to which the request is directed, and an address of a target buffer located outside of the secondary storage system for holding data involved in the request. Next, the system processes the request by transferring data between the location within the secondary storage system and the target buffer located outside of the secondary storage system. If the target buffer is located within a page cache, processing the request involves communicating with the target buffer located within the page cache.

Abstract: A proxy server containing a cache for retrieving information from a server and transmitting this information to multiple concurrent clients. A thread is created for each client requesting the information from the server. As long as information is contained in the cache, all the threads assume the role of a consumer thread by retrieving this information from the cache and placing it in an output stream to be sent to the client associated with each consumer thread. When one of the threads reaches the end of the information contained in the cache, it assumes the role of a producer to send a request to the server to retrieve additional information. When the producer thread receives the information from the server, it places it in an input stream for the cache. The producer thread then reverts back to a consumer thread to retrieve this information for its associated client. All other consumer threads may also retrieve this data from the cache.

Abstract: The problem of searching for a low cost path from a source location to a target location through a traversable region partitioned into a plurality of tiles is solved using source and target cost functions. Each tile in the traversable region is defined by boundary segments. The source cost function provides a cost for traversing from the source location to the boundary segment in question. The target cost function provides a cost for traversing from the boundary segment in question to the target location. The target cost function is estimated, and the source cost function is calculated. A path cost function is determined by adding the source and target cost functions. If the target location is a tile, then the target cost may be estimated using a convex hull of the target tile and the boundary segment in question. To facilitate the cost function calculations, multiple forms of cost function propagation between segments are disclosed.

Abstract: An apparatus and method are provided for damping a noise component of a power signal from a power source. The apparatus and method are able to produce a load current in phase with the noise component to lower an effective impedance of a circuit driven by the power source to damp the noise component. The apparatus and method are able to produce the load current in phase with the noise component between a first cutoff frequency and a second cutoff frequency. The first cutoff frequency is determined in part by a time constant and the second cutoff frequency is determined in part by the physical properties of the materials that form the apparatus.

Abstract: A graphical user interface (GUI) is configurable in an embodiment of the invention. A user configures sliding panels located on the edges of the GUI. A sliding panel is configured with an application that runs in the sliding panel. The sliding panel is present in the GUI in either a closed or an open representation. The sliding panel's GUI representation is determined based on the position of the user's cursor. When the cursor is within a closed sliding panel's closed representation, the sliding panel is expanded to its open representation. By moving the cursor outside the sliding panel, the user can close the panel. There is no need for the user to consciously manage the elements in the GUI. The elements are managed based on the configuration information supplied by the user and the information available at runtime.

Abstract: Automated patching techniques to correct certain rule violations are used, simplifying and automating the design layout of an electronic circuit, whether embodied as a design encoding or as a fabricated electronic circuit. A series of patches of predefined orientations are utilized to correct design rule violations. A set of violations are identified, patches of a predefined orientation are attempted to correct one or more violations. Patches of another predefined orientation are attempted to correct remaining violations. Attempted patching is repeated until all patches in the series have been attempted or all violations have been corrected. Patches can be added to a construction layer over the set of violations, and each patch that does not cause a design rule violation can be copied to a metal layer. A series of patches of predefined orientations are used, efficiently correcting design rule violations such as minimum area and jog rule violations.

Abstract: A prefetching technique for a network interface is provided to give the network interface the opportunity to prefetch data out-of-order into send queues in the network interface, rather than prefetching data in the order produced and deposited into main memory. That allows, the state of the send queues to be taken into consideration when deciding an appropriate order to prefetch data.

Abstract: A method for private personal identification number (PIN) management comprises ascertaining a first delay period of a preceding PIN.
