Abstract:
Methods for managing contents of multiple digital documents for individual users, to generate aggregated documents from multiple documents and/or create associations among multiple documents, based on the user's interactions with multiple digital documents. A document content aggregation method can, on a personalized basis, aggregate contents from multiple digital documents into an aggregated document based on a user's past interactions with the documents. The aggregation is based on a content importance score calculated from the user interaction pattern. A document association method can, on a personalized basis, create associations among multiple digital documents based on the user's past interactions with the documents. Two documents are deemed related if there is a user interaction pattern where the user interacts with both documents with a predetermined time interval from each other. When displaying one document, link icons are displayed to allow the user to directly navigate to the related documents.
Abstract:
A method for automating the management and interpretation of digital documents and their rights metadata to generate user access of a document protected by digital rights management (DRM), comprising the steps of a server obtaining a digital document and its associated rights metadata, the server interpreting the metadata to ascertain DRM useful information including identifications (IDs) of the document and its users and associated digital rights, and the server generating entries for a DRM database including policies associated with the document ID and users IDs based on the ascertained DRM useful information to enable DRM protection to the document.
Abstract:
A method of detecting a defect in a barrier film. The method includes: coating the barrier film with a solution having a plurality of probes, where each of the probes has a nanoparticle; forcing a probe of the plurality of probes to penetrate the defect by applying a field to the barrier film, where the field induces an attractive power to the nanoparticles of the probes; applying an optical excitation (OE) to the barrier film; and identifying the defect in the barrier film based on an optical signal emitted, in response to the OE, by the probe forced to penetrate the defect.
Abstract:
A method, computer program product, and a system for enhancing an interaction between a teacher and a student are disclosed, the method includes receiving video images of a region of interest from a plurality of multi-functional devices; comparing the video images of the region of interest received from the plurality of multi-functional devices; detecting differences in the region of interest of at least one multi-functional device in comparison to the region of interest of the plurality of multi-functional devices; and providing a signal to the at least one multi-functional device based on the detected difference in the region of interest.
Abstract:
A digital rights management (DRM or RMS) method allows the operator of a scanner, connected to an RMS server, to associate a digital document with user access rights that are different from the rights defined by any of the existing DRM policies on the server. The method allows the operator to choose one of the existing policies on the server, and modify the user access rights by granting rights to additional users and/or removing rights of some users that would be granted by that policy, to generate modified user access rights for a document without changing any existing policies or adding new policies. The server stores the document ID, polity ID and the user access rights (modified or unmodified) in a rights association table on the server. The method is also applicable when importing documents into the DRM system from sources other than scanners.
Abstract:
A method for encoding and decoding color barcodes to increase their data capacity. The encoding steps include determining a shape, a foreground color and a background color for each data cell, wherein a combination of the shape, foreground and background colors for the data cell is chosen from a plurality of such combinations in accordance with a value of the digital data to be encoded; and coloring some pixels in the data cell with a foreground color and other pixels with a background color, in accordance with the shape, foreground and background colors for the data cell determined above. The decoding steps include segmenting the data cells, recognizing a shape, a foreground color of the shape and a background color of the data cell, and obtaining digital data from a combination of the shape and foreground and background colors in each data cell.
Abstract:
Method and system for processing a page-image based input document such as PDF and generate output documents, in a page-image based format or another format, which have a different layout than the original document. Certain contents in the original document removed and other contents are reorganized in this process. The method is used to re-target documents for different types of display devices, such as desktop and laptop computers, tablet computers, e-readers, smart phones, etc. When generating the output documents, the method takes into consideration the different form factors of the display devices as well as the different types of user input devices and methods such as touch screen (including different gestures used, whether stylus or finger is used for input, etc.), physical keyboard, mouse, etc. used by the targeted display device, so that each output documents is optimized for a particular type of display device.
Abstract:
A method for rendering an electronic document (ED) includes: receiving a request to render the ED; initiating, by a main process thread, generation of a main display list (DL) for the ED; identifying, during generation of the main DL, a first self-contained graphical structure (SCGS) within the ED; generating, by the main process thread, a first auxiliary DL for the first SCGS; inserting a reference to the first auxiliary DL into the main DL; initiating, after completion of the first auxiliary DL, rasterization of the first auxiliary DL by a first rasterization thread; resuming, by the main process thread and during rasterization of the first auxiliary DL, generation of the main DL; and rasterizing, after completion of the main DL, the main DL based on a first pixmap generated by rasterization of the first auxiliary DL.
Abstract:
A method is disclosed managing at least one print media database server for print media attributes of print media, which includes hosting print media attributes for a plurality of image forming apparatuses on the at least one print media database server, and the at least one print media database server contains print media attributes for a plurality of print media; receiving, by the at least one print media database server, additional print media attributes from one of the plurality of image forming apparatuses; confirming accuracy of the additional print media attributes; and releasing, by the at least one print media database server, the additional print media attributes in the print media database to the plurality of image forming apparatuses after the accuracy of the additional print media attributes is confirmed, thereby sharing the additional print media attributes in the print media database among the plurality of image forming apparatuses.
Abstract:
A method for managing an electronic document (ED), including: receiving a request to generate an obfuscated page-description language (PDL) file for the ED; identifying, within the ED, a first text flow comprising a plurality of characters; calculating a plurality of positions on a page for the plurality of characters; generating, in response to the request, a modified text flow by applying an obfuscation technique to the first text flow; and generating the obfuscated PDL file comprising the plurality of positions and the modified text flow.
