  • Patent number: 8867333
    Abstract: A method for determining a restoration path for a new service in a mesh network involves selecting between candidate restoration paths corresponding to a primary path for the new service based on the shared-risk link groups (SRLGs) associated with links in the primary path. The method includes, for each of a plurality of candidate restoration paths associated with the primary path, (1) determining whether the primary path requires any additional restoration bandwidth to be reserved on any link of the restoration path based on whether, for each link of the restoration path, the primary path is SRLG-disjoint from each other primary path that is protected by that link, (2) generating a path cost for the restoration path, where the path cost is a function of whether any additional restoration bandwidth is required; and (3) selecting the restoration path for the new service based on the path cost.

  • Patent number: 8751411
    Abstract: Disclosed herein is a method and system for determining a billing structure for outputting documents using an image processing apparatus. If image data of the document includes color pixels, a billing structure is determined based on an estimated total color pixel count. The color pixels of the image data are counted in a device independent space and the total color pixel count of the image data to be output in a device dependent space is estimated. Based on the estimation, a billing structure is chosen. Processing and determining a billing structure based on image data in the device independent space avoids charging a customer for color print job when only a small amount of color pixels are printed. It also encourages determining charges independently of the marking engine or output device.

  • Patent number: 8508786
    Abstract: A system and method of billing for scanning service costs is provided to examine content of a page and apply a cost function to approximate the cost of scanning the page. Examining the page includes detecting an object in the page, determining a type of the detected object, determining an approximate file size of the page, and determining an approximate area of coverage of the detected object within the page. A usage profile of each type of detected object is calculated and stored. The cost function uses the detected object, the approximate file size, the approximate area of coverage, and a weight value associated with the type of detected object to approximate the cost of the page. When costs are calculated over a period of time, the weight value of each type of detected object may be adjusted based on the usage profile for each type of detected object.

  • Patent number: 8494281
    Abstract: An automated method and system for retrieving documents based on highlighted text from a scanned source. Documents that are stored within a multifunction device can be searched and retrieved using highlighted text as keyword. The search of such documents can further be extended towards other networked multifunction devices and also to retrieve information available on the Internet using highlighted text as a uniform resource locator pointer. The matched documents and their respective details are then displayed on a graphical user interface which provides the user with multiple actions to be taken with respect to the documents.

  • Patent number: 8494280
    Abstract: An automated method for extracting highlighted regions in a scanned text documents includes color masking of highlight regions, extracting text from highlighted regions, recognizing the characters in extracted text optically and inserting the recognized characters to new document in order to easily identify highlighted text in scanned images. Using a two-layer multi-mask compression technology configured in a scanned export image path, edges and text regions can be extracted and together with the use of mask coordinates and associated mask colors, all highlighted texts can be easily identified and extracted. Optical Character Recognition (OCR) can then be utilized to appropriate summarization of different extracted highlighted texts.

  • Patent number: 8462394
    Abstract: Systems and methods are described that facilitate determining an original document format for a scanned document by analyzing a bitmap thereof. Text objects are extracted from the document, binarized, and segmented to identify text. Page orientation and text size are used to distinguish between a slideshow-type document, and a word processing or spreadsheet-type document. To further distinguish between the word processing and spreadsheet types, text column structure and count is analyzed.

  • Patent number: 8422448
    Abstract: A method and system for group call control in a broadband wireless network. A group call (push-to-talk) server initiates and regulates group call communication sessions. A wireless base station communicates with one or more group call participants. When a request to participate in a group call is received, it is examined to see if it contains a group call ID or other group call indicator. If not, regular call resources are allocated, if available. If so, it is determined whether another group member is attached to the base station. Group call resources are then reserved, if available, based on this determination. The resources allocated for the group call may also depend on whether the system supports multicast on the downlink to group members, or whether losing audio is supported. In some embodiments, network resources may be reallocated to support the group call.

  • Patent number: 8423900
    Abstract: What is disclosed is a resizing method that utilizes segmentation information to classify objects found within a document and then selects the most appropriate resizing technique for each identified object. The present method employs readily available document parsers to reliably extract objects. e.g. text, background, images, graphics, etc., which compose the document. Information obtained from a document parser is utilized to identify the document components for classification. The extracted objects are then classified according to their object type. Each of classified objects are then resized using a resizing technique having been pre-selected for the object type based on their respective abilities to resize certain types of document content over other resizing techniques. The present method advantageously extends smart or content-based scaling and is especially useful for N-up or variable-information printing.
