International Classification:

G06F 7/00

US Classification:

707 8, 707201

Abstract:

A file locking method and implementation are disclosed which allows a plurality of user sessions to open and read a file, but at any one time, only one session will be allowed to change the data displayed in the browser window and to update the file. This file locking method sets up a file access priority by using file locks that are date-time stamped and session stamped. The types of lock associated with the present invention include read lock, authority lock, write lock, and folder lock. When a session/user requests access to a file, the application will check a lock table associated with the requested file. For each lock on the file, there is an entry in the lock table for each of the attributes of the lock: lock type, session owner, date-time stamp. Depending on the lock and the existing locks on the file, the requesting session may be granted a lock. After the access request is fulfilled, the file lock may be removed.

US Classification:

709224, 709203

Abstract:

This invention is directed to a system and method for tracking sessions for web-based applications. The system and method comprise a browser disposed on an associated data terminal and having at least one browser window associated therewith. The browser is adapted to generate at least one interactive session with an associated web server. The system and method also comprises at least one session tracking application associated with an interactive session. The session tracking application includes monitoring means adapted for monitoring activity on the associated interactive session and testing means adapted for determining whether monitored activity includes an unload event. The session tracking application also includes termination means adapted for terminating the associated interactive session upon a determination of a selected unload event and notification means adapted for notifying the associated web server to close out the interactive session.

International Classification:

G06F 17/28

US Classification:

704 7, 704 8, 704 9, 704257

Abstract:

An architecture for universal data communication between a network client and a web server. A web server receives a character string from the network client for storing. The web server encodes and then stores the string. Any character that is not a 7 bit ASCII character is encoded by encapsulating it with an escape code, the escape code comprised of an illegal character. Upon a request to retrieve the encoded string, the web server decodes and converts to UTF8 the encoded character string. When a client or browser requests the folder or document containing the encoded string, the string is properly displayed in the client's or browser's native language.

US Classification:

358 111, 358 115, 358 11

Abstract:

This invention is directed to a system and method for storing font image data, which is already rendered, in a history-based order on the server side. This avoids the server side processing time to render the font every time a request is received. This allows users to use many server side fonts that users may not have on their client workstations. In the method, the user uses a web browser to choose a font type, size, and style from a list of available fonts installed on the server. The system then determines if the selected font exists in the font repository. If the font exists, the system retrieves the font images from the font repository. If the font does not exist, the system creates the font images and stores the font images to the font repository.

Abstract:

The subject application is directed to a system and method for generating a graphical user input interface via an associated graphical user interface. Data representative of a user input interface from storage. Preferably, this data includes graphical representations of each character associated with a standard QWERTY keyboard, inclusive of modified characters. The retrieved graphical data is then used to generate a user input interface on an associated touch screen. The user then selects a character from those characters displayed via the touch screen. The selected character is then displayed to the user in an associated data field.

US Classification:

358 115, 709201

Abstract:

A system and method for selective rerouting of document processing jobs is provided. A printer driver first converts electronic document data is into a device compatible format and assigned a unique document ID. The printer driver then determines a set of network devices, such as document processing devices, that are participating in the performance of received document processing jobs. The converted document data is then divided into portions and one or more portions are then sent to each of the participating network devices. One of the devices is then selected as the output device, whereupon the output device broadcasts/multicasts a request for processed data portions from each of the other network devices. The received portions are then recombined, and released for further processing in accordance with the received document processing job.
