  • Patent number: 7559078
    Abstract: A resource allocation of multiple compressed AV streams delivered over the Internet is disclosed that achieves end-to-end optimal quality through a multimedia streaming TCP-friendly transport (MSTFP) protocol that adaptively estimates the network bandwidth while smoothing the sending rate. Resources allocated dynamically according to a media encoding distortion and network degradation algorithm. A scheme is also disclosed for dynamically estimating the available network bandwidth for streaming of objects, such as MPEG4 multiple video objects, in conjunction with the MSTFP protocol. The scheme can account for packet-loss rates to minimize end-to-end distortion for media delivery.

  • Patent number: 7558244
    Abstract: An implementation of a technology, described herein, for transmitting compressed network transport-layer-protocol headers in a speedy, efficient, inferentially synchronized, and robust manner. An implementation, described herein, models the transmission of compressed headers to the congestion procedure of the network transport-layer protocol (e.g., TCP's). Doing so, the sender of the compressed headers can infer whether the receiver correctly received them. Unlike the slow direct synchronization employed by conventional schemes, this implementation of the present claimed invention inferentially synchronizes by modeling after the congestion procedure of the network transport-layer protocol. This is inherently faster than direct synchronization. Since the implementation performs well over both noiseless and noisy links, it is particularly suited to use over wireless communications channels. This abstract itself is not intended to limit the scope of this patent.

  • Publication number: 20090156253
    Abstract: Various embodiments for providing fully qualified domain name (FDQN) resolution for a home network realm based on an International Mobile Subscriber Identity (IMSI) are described. In one embodiment, a mobile computing device may be arranged to retrieve an IMSI including a Mobile Country Code (MCC) and a Mobile Network Code (MNC) and to derive an initial FQDN from the IMSI using an initial MNC rule. The mobile computing device may transmit an initial domain name system (DNS) request comprising the initial FQDN. The mobile computing device may be arranged to derive an alternate FQDN from the IMSI using an alternate MNC rule and to transmit a subsequent DNS request comprising the alternate FQDN when a DNS error message is received in response to the initial DNS request. Other embodiments are described and claimed.

  • Publication number: 20090032279
    Abstract: A user-manipulated door mechanism is mounted on the faceplate of an electronic module for allowing user access to an electrical socket disposed inboard of a faceplate aperture. An inwardly extending rectangular shoulder formed along one edge of the door is rotatably mounted about an axis inboard of the faceplate, and is resiliently engaged by the free end of a cantilevered spring blade inboard of the faceplate. The spring blade engages a first face of the shoulder that is substantially parallel to the door when the door is in a closed position covering the socket, and a second face of the shoulder that is substantially perpendicular to the door when the door is in an open position uncovering the socket.

  • Publication number: 20080266782
    Abstract: A keyboard device includes a substrate having top and bottom surfaces, and through holes extending from the top surface to the bottom surface. The bottom surface is formed with an air guide groove unit in fluid communication with each through hole. A sealing layer is mounted sealingly on the bottom surface of the substrate such that the through holes and the air guide groove unit constitute an air passage. A wiring board is mounted on the substrate. When a key cap disposed above a corresponding through hole in the substrate is pressed downwardly, a resilient tubular support member disposed between the key cap and the wiring board deforms such that air in the support member is urged into the air passage.

  • Publication number: 20070299707
    Abstract: The present invention relates to designating that durations of specific tasks are estimated or tentative. The user can indicate estimated durations by the sheet mode or the dialog mode. Estimated duration characters are symbols of uncertainty, such as “?”, that indicate that the duration entries are not fixed and final, but may need to be adjusted in the future. The user can select an option to not display the estimated duration character even though the estimated field for the task is set. The user can also select an option to have new tasks that are created have estimated duration characters until the user chooses to enter a duration value. The program can also filter the task list to display only tasks that have estimated duration characters.

  • Patent number: 7305140
    Abstract: An image distribution system has a source that encodes digital images and transmits them over an error-prone channel to a destination. The source has an image coder that processes the digital images using vector transformation followed by vector quantization. This produces groups of vectors and quantized values that are representative of the images. The image coder orders the vectors in the codebooks and assigns vector indexes to the vectors such that a bit error occurring at a less significant bit in a vector index results in less distortion than a bit error occurring at a more significant bit. Depending upon the format and the capabilities of the source and destination, the image coder may allocate different numbers of bits to different groups of vectors according to a bit allocation map for this allocation process. The source also has a UEP (Unequal Error Protection) coder that layers the vector indexes according to their significance.

  • Patent number: 7269289
    Abstract: A video encoding scheme employs progressive fine-granularity layered coding to encode video data frames into multiple layers, including a base layer of comparatively low quality video and multiple enhancement layers of increasingly higher quality video. Some of the enhancement layers in a current frame are predicted from at least one lower quality layer in a reference frame, whereby the lower quality layer is not necessarily the base layer.
