Patent number: 8583691Abstract: A process for viewing document information on a mobile communication device without having to retrieve the full document onto the device. The solution is client-server based. The client is the mobile device attachment viewing application and the server is the document (attachment) handling process on a remote machine. The process comprises server document information construction and delivery, and document information display on the mobile device.Type: GrantFiled: July 27, 2011Date of Patent: November 12, 2013Assignee: Blackberry LimitedInventors: Jainwei Oliver Yuan, Olav A.

Patent number: 8584037Abstract: A process is set forth for viewing an enlarged area of an image. The image is stored on a server and re-sized for viewing on a mobile communication device based on screen size and color display capabilities of the device. The image is enlarged within the server by modifying binary raw data of the original image based on crop rectangle coordinates entered at the mobile communication device. The process allows users to quickly retrieve any relevant part of a large image attachment that has been resized by the server. This minimizes bandwidth usage, device memory/CPU consumption, and request/response latency while still allowing the user to view an image area in its original level of detail.Type: GrantFiled: May 9, 2012Date of Patent: November 12, 2013Assignee: BlackBerry LimitedInventors: Olav A.

Patent number: 8069410Abstract: Systems and methods of retrieving and presenting partial (skipped) document content are provided. A typical system includes a document parsing stage, a device request for content stage and a delivery of requested content stage. A target device can include a device presentation of the requested content stage. The system parses the content of an electronic document and generates a document object model (DOM) representation of the electronic document, where each source and destination target is assigned a document object model identifier (DOM ID). In some instances, upon completion of parsing, the document object model is then paginated in computer memory into segments of a certain size called chunks; in such instances the pagination operation can update each DOM ID with an additional information attribute containing the chunk index with the purpose of establishing a relationship between a document object model identifier and the corresponding chunk index.Type: GrantFiled: February 25, 2008Date of Patent: November 29, 2011Assignee: Research In Motion LimitedInventors: Olav A.
