A composite image is generated from a decorative image, a bar code, and one or more filter patterns. The composite image visually approximates the decorative image, yet the composite image is machine-readable by a scanner capable of reading the bar code, and the composite image encodes the same data as the bar code. Filter patterns provide a flexible way to generate the composite image by selectively updating the decorative image. Updates may be applied in only the locations where necessary, and only by the amount necessary, in order for the composite image to be recognized as a bar code. Also, updates may be applied in arbitrary color spaces, including color spaces where brightness can be altered with less impact on human color perception.

Generating a decorative image bar code using filter patterns

One embodiment of the present invention provides a system that facilitates intercepting browser communication protocol requests at a client. In addition, the system optionally fulfills the requests with content which is locally cached on the client rather than with content from a web server, which is located externally from the client. During operation, the system receives a communication protocol request at a browser's communication protocol stack. In response to the request, the system identifies a Uniform Resource Locator (URL) for the request. The system also determines if an item of content identified by the URL can be retrieved from a local cache. If so, the system fulfills the request from the local cache.

One embodiment of the present invention provides a system that extends a scripting language native to a web browser to facilitate executing scripts within a web browser. During operation, the system receives a first command from a root script to initialize a first worker script within a web browser. In response to the first command, the system: creates a first operating-system thread, wherein the first operating-system thread is associated with a first message queue; starts a first worker script-engine using the first operating-system thread; receives a first message at the first message queue to execute the first worker script; and in response to the first message, executes the first worker script within the first worker script-engine.

Method and apparatus for executing scripts within a web browser

Systems and methods for information capture from articles are described. In one embodiment, a plurality of keystrokes associated with an application is received, each keystroke is processed to determine an associated action forming a plurality of associated actions, and an event is determined based at least in part on the plurality of associated actions.

Methods and systems for information capture

A database engine embedded within a browser implements a system that facilitates managing client-side data for web-based applications. During operation, the system receives a Uniform Resource Locator (URL) at the browser. The system then retrieves a web-page associated with the URL. Next, the system executes a script associated with the web-page. While executing this script, the system receives a request to open a database. In response to this request, the system uses the database engine to open a database associated with the web-page, wherein the database engine is embedded in the browser. The system then uses the database engine to execute database commands.

Facilitating client-side data-management for web-based applications

An indexing system in a computer system may include applications, a capture processor, a queue, a search engine, and a display processor. The indexing system captures events of user interactions with the applications. Events are queued and if indexable, indexed and stored for user access through the search engine. Capture components in the capture processor can include a keyboard capture component that processes user keystrokes to determine events. A display capture component captures event data from windows associated with the applications. Display event data can be captured on a polling schedule or based on state changes of window elements. To determine target applications and window applications of interest application profiles and window profiles can be used.

Profile based capture component

Methods and systems that identify a representative image for an article are described. In one aspect of the invention, an article is received, an image data signal is determined for each image associated with the article, and a representative image based at least in part on an image data signal is determined.
