Title: System for adaptive video/audio transport over a network
Inventor: ARIEL OREN
IPC: H04N7/26
Filed: 1998-06-25
Granted: 2002-04-02
Abstract: A system for adaptively transporting video over networks wherein the available bandwidth varies with time. The system comprises a video/audio codec that functions to compress, code, decode and decompress video streams that are transmitted over networks having available banwidths that vary with time and location. Depending on the channel bandwidth, the system adjusts the compression ratio to accomodate a plurality of bandwidths ranging from 20 Kbps for POTS to several Mbps for switched LAN and ATM environments. Bandwidth adjustability is provided by offering a trade off between video resolution, frame rate and individual frame quality. The system generates a video data stream comprised of Key, P and B frames from a raw source of video. Each frame type is further comprised of multiple levels of data representing varying degrees of quality. In addition, several video server platforms can be utilized in tandem to transmit video/audio information with each video server platform transmitting information for a single compression/resolution level.

Title: Wind driven turbine
Inventor: YOUSIF OSSAMA I I
IPC: F03D3/04
Filed: 2000-02-11
Granted: 2003-01-28
Abstract: This invention relates to vertical and horizontal axle wind turbines. In particular, to a device that takes in all the wind cross section facing it, and with minimum loss on frictional and mechanical resistance, puts it to work to spin a generator, for instance. It's superiority is revealed in it's ability to increase wind energy by increasing air density in wind compaction tunnels, then gradually releasing that into smaller wind turbines which can work separately, in pairs, and groups, on one or more generator, and can be stacked in an airtight fashion.  Thus the device can produce at wind velocities from the very low to the structural damaging. The invention is customer innovation driven with a universal, industrial, commercial and retail application.

Abstract: An image encoder/decoder by which a partial image is encoded easily with a resolution meeting the user's demand, the encoded amount of data is not increased and a necessary capacity of memory can be reduced. The image encoder has a tile decomposition portion which divides image data into tiles of N pixels x M pixels, a wavelet transform coding portion which extrapolates predetermined data at the peripheries of the tiles outputted from the tile decomposition portion and performs subdivision to perform wavelet encoding, a management information generating portion which generates information for managing the encoded data in order that the encoded data outputted from the wavelet transform coding portion can be decoded for each tile and for each subband of the wavelet encoding, and a coded data integration portion which links the encoded data encoded by wavelet encoding for each tile by using the output of the management information generating portion and adds the managing information to the encoded data.

Each frame includes a label block containing label information of the frame, and two or more respective payload blocks having a predetermined length. The label block contains encoded routing information, a start time, and, possibly an end time, and is transmitted over a label channel of the communications network. The start time preferably indicates a delay between launching a first bit of the label clock and the first bit of the payload blocks. The end time may be a bit count indicative of the location of the last bit of the data packet within the frame. The data packet is divided into a plurality of data segments, each of which is transported across the network within a respective payload block. Each payload block is transmitted over a respective separate data channel of the communications network. Routing control of the frame may be handled using the multi-protocol label switch (MPLS) protocol.

Title: Method and apparatus for managing polling request in data communications
Inventor: JOHANSSON MATHIAS
IPC: H04L12/56
Filed: 2000-02-11
Granted: 2012-05-01
Abstract: The present invention improves the reliability of data communication by analyzing plural data units in a group or a block rather than analyzing individual data units. For example, at the time that a transmitter desires or needs to send a polling request to a receiver, there may be more than one data unit available for delivery as a group. All of the polling fields of the data units in this group are set to indicate a poll request. When the receiver receives this group of data units, it sends the requested status information to the transmitter if the polling field of at least one of the received data units in the group indicates a poll request. Moreover, if the polling field of plural ones of the data units in the group indicates a polling request, the receiver sends the requested status information only once.
