  • Publication number: 20080120360
    Abstract: A method for downloading an attachment to an attachment viewer of a portable electronic device includes: sending an initial data request from the attachment viewer to a server in response to receipt of an email message including the attachment, building and storing a graph structure within the server representing a map of the attachment, encapsulating the graph structure in data having an attachment viewer readable format and sending an initial chunk of the data to the attachment viewer, the initial chunk of the data being stored on the portable electronic device. The initial chunk of the data is received by the portable electronic device prior to a request to view the attachment being selected by a user.

  • Publication number: 20080104515
    Abstract: Displaying slide presentations in a user interface (UI) on a display screen is enhanced by providing multiple display modes in a slide presentation viewer. A text mode shows text information distilled from the slides. A preview mode shows thumbnail slide images rendered from the slides and a mixed mode shows text information and thumbnails together. The UI further provides a slide show to display the slide images in full screen and an interface (e.g. menu) for selecting among the modes and invoking the slide show. For wireless devices in particular, a network server may process slide presentation documents to generate the text information and slide images for communicating to the wireless devices having slide presentation viewers. The network server may be an attachment server providing services for email attachments and the slide presentation viewers may be attachment viewers.

  • Patent number: 7363582
    Abstract: 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.

  • Publication number: 20070266010
    Abstract: A server find process by which a user enters a search term for a document attachment into his/her mobile communication device. If no occurrences of the term are found on the device, the device then prompts the user to initiate a server side search. If the user accepts, then the server searches the document attachment and returns the first section of text that contains the search term to the device for viewing by the user. This process can then be repeated until the server find feature reports that no further instances of the search string have been found on the server.

  • Publication number: 20060225001
    Abstract: A process is set forth for previewing a table attachment on a mobile communication device, and upon identifying table content of interest viewing and/or retrieving the entire table from an attachment server. In one embodiment, a small 4×4 row/column preview is presented on the device of every table found in a document attachment, with the cell content textual information limited to the requesting device display capabilities. This limitation avoids any requirement to download large amounts of individual cell content to the device. Thus, the user is able to quickly identify which tables are of interest and then request a full table download from the attachment server in an on-demand fashion. In this regard, the preview table itself preferably also functions as a link to the full table stored at the server to facilitate easy retrieval to the device for viewing in a spreadsheet view.

  • Publication number: 20060055693
    Abstract: 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 colour 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.

  • Patent number: 6883871
    Abstract: An armrest adjustment mechanism for use with a vehicle seat defining a lateral seat axis and an armrest member defining a longitudinal axis. The mechanism includes a mounting system for pivotally mounting the armrest member on the vehicle seat for selective pivotal rotation about the lateral seat axis between a deployed design configuration, wherein the longitudinal axis has a substantially horizontal orientation, and a raised stowed configuration, wherein the longitudinal axis has a substantially vertical orientation. The mechanism also includes a lateral translation system for positive inward displacement of the armrest member along the lateral seat axis relative to the vehicle seat as the armrest member is rotated from the deployed design configuration towards the raised stowed configuration.

  • Patent number: 6827404
    Abstract: A fold flat vehicle seat comprises a seat assembly mounted on a movable track member slidably engaging a fixed track member, and lockable by a track lock. The seat assembly includes a seatback member mounted on a seat cushion member for forward folding between a substantially upright occupiable design position and a substantially horizontal load supporting position. A downwardly and rearwardly sloped ramp is mounted on the fixed track member. A drive link assembly is mounted on the seatback member for translational engagement of a ramp contact member with the ramp. As the seatback member is forwardly folded from the upright occupiable design position to the load supporting position the track lock releases and the ramp contact member moves downwardly and rearwardly along the ramp to thereby cause rearward longitudinal movement of the seat assembly relative to the fixed track member to a predetermined rear longitudinal position.

  • Publication number: 20040126823
    Abstract: The present invention discloses novel methods to identify compounds potentially useful for the treatment and prevention of inflammation and/or cancer in animals including mammals. It disclose that Tpl2 is required for tumor induction by Akt and Tpl2 is required for the induction of cyclo-oxygenase-2 (COX-2) and prostaglandin synthesis and provides methods to identify compounds that modulate interactions between Tpl-2 and COX-2 or interactions between Tpl-2 and Akt. The present invention also discloses a transgenic Tpl2−/− mouse encoding Akt where the mouse is characterized by its ability to show delayed tumor induction by comparison with a transgenic Tpl2+/+ mouse expressing the Akt and method of treating cancers in animals.
