  • Publication number: 20090083433
    Abstract: A new P2P streaming method and apparatus disseminates video chunks to all peers with the minimum (or at least reduced) delay. After obtaining a new video chunk, a peer keeps transmitting (uploading) that video chunk to other peers until all peers receive it. The approach quickly increases the aggregate bandwidth that can be utilized to transmit a video chunk. For example, the aggregate peer bandwidth used to transmit a video chunk can double every time slot. For a homogeneous P2P streaming system with N peers, a time slot is defined as a unit of the single chunk transmission delay between two peers. Using the P2P streaming method, a video chunk can be disseminated to all peers within 1+log2 N time slots.

  • Patent number: 7503498
    Abstract: A hand-supportable digital image capture and processing system comprises: an area-type image formation and detection subsystem having an area-type image detection array; an LED-based illumination subsystem having a LED-based illumination array; an automatic light exposure measurement and illumination control subsystem; an image capturing and buffering subsystem; and an image-processing subsystem. The LED array is automatically driven in a precise manner to globally expose the area-type image detection array with LED-based illumination only when substantially all of its rows of pixels are in a state of integration and have a common integration time, thereby enabling the capture of high quality images independent of the relative motion between the object and the hand-supportable digital image capture and processing system.

  • Publication number: 20090065584
    Abstract: A POS-based digital image capturing and processing system for illuminating objects using automatic object detection and spectral-mixing illumination technique. The system comprises an area-type illumination and imaging station for projecting a coextensive area-type illumination and imaging field (i.e. zone) into a 3D imaging volume during object illumination and imaging operations. The area-type illumination and imaging station includes an illumination subsystem for producing a first field of visible illumination from an array of visible LEDs, and producing a second field of invisible illumination from an array of infrared (IR) LEDs. wherein the first and second fields of illumination spatially overlap and intermix with each other and are substantially coextensive with the FOV of the image sensing array.

  • Patent number: 7450553
    Abstract: A system and method for selecting a starting point to transmit a beacon (BTSP) from a coordinator and a first node in a communication system. The communication system includes the coordinator, a first node group with at least one node having the first node which receives the beacon from the coordinator, and a second node group with at least one node having a second node which receives the beacon from the first node. The coordinator determines a beacon window size for the beacon transmission, selects the BTSP within the beacon window size, and transmits at the BTSP, the beacon containing information on the beacon window size and the BTSP. The first node selects its BTSP within the beacon window size so as not to overlap with the BTSP of the received beacon.

  • Patent number: 7450521
    Abstract: A routing method comprising receiving a first packet, the first packet being broadcast for discovery of a route. A first backoff of the first packet is calculated based on a route cost of the first packet. The first packet is rebroadcast if a second packet is not received within the first backoff, the second packet being a duplicate of the first packet. A second backoff of the second packet is calculated based on a route cost of the second packet if the second packet is received within the first backoff. One of the first and the second packets is rebroadcast as a result of comparing the first backoff and the second backoff.
