Title: Flumes for manhole inverts
Inventor: DURAN LEE A
IPC: E03F5/02
Filed: 1996-05-08
Granted: 2002-07-30
Abstract: Flumes for manhole inverts are described and formed of integrally molded segments which interfit with each other so as to connect inlets to an outlet of a manhole independent of the shape and size of the manhole.      The flumes are made in a set and in one set the flumes are formed of a pipe segment which either is integrally connected to an open channel segment or connected thereto with suitable fasteners and with the overall length of the flume being substantially less than the distance between the inlet and an outlet of the manhole. Another set of flumes has only open channel segments which are generally substantially smaller in length than the fumes which have both a pipe and an open channel segment. The open channel segments are provided with end flanges to enable their connection to similarly shaped channel segments to form inverts.

Title: Method and apparatus for encoding and formatting data representing a video program to provide multiple overlapping presentations of the video program
Inventor: KRAUSE EDWARD A
IPC: H04N7/173
Filed: 1995-10-19
Granted: 2002-12-31
Abstract: Virtually random and on-demand access is provided to a virtually unlimited number of subscribers by partitioning the video program into an ordered sequence of n segments and providing the subscribers concurrent access to each of the n subsequences.  A data stream representative of the video program is positioned into n subsequences, each representative of one of the n segments.  The data of each of the n subsequences is organized as ordered sequence of elements. The elements of each of the n subsequences are interleaved and the interleaved data stream is continuously transmitted over a video program distribution medium at a rate which renders the date representing each segment concurrently available to any subscriber having a receiver capable of selecting, assembling, and displaying the data of a particular segment.  The date stream can be compressed prior to interleaving using one of many known video data compression standards and techniques. Data compression can be performed in real time, or iteratively using software.  The interleaved data stream can be transmitted in real time, or it can be stored on a storage device such as a hard disk or optical disk for later retrieval and transmission.  The interleaved data stream can be ordered using any known standard by which video data is transmitted for reconstruction and display by a receiver.  Data can be inserted into the interleaved data stream to inform the receiver to which of the n segments a portion of the interleaved data stream belongs, as well as the encoding level necessary for decompression of the data and time stamps to indicate order of display.  Thus, the receiver may begin reconstruction from the beginning of the video program by selecting, assembling, decompressing and displaying the data making up the first segment during a first complete transmission of the interleaved data stream, and performing the same function for the succeeding segments during subsequent transmissions.  The receiver can also be programmed to reconstruct any of the n segments in no particular order, approximately random access to the video program.

Title: Three-dimensional braided covered stent
Inventor: THOMPSON PAUL J
IPC: A61F2/06
Filed: 1997-04-15
Granted: 2004-08-17
Abstract: A prothesis (18, 108, 120) for transluminal implantation consists of a flexible tubular three-dimensionally braided structure of metal or polymeric monofilaments (32, 110, 126), and polymeric multifilament yarns (42). The prosthesis can be elastically deformed to reduce its diameter through axial elongation. The monofilaments and multifilament yarns are arranged in axially spaced apart helices, concentric on a common central axis of the prosthesis. The monofilaments are selectively shaped before their interbraiding with the multifilament yarns, either by an age-hardening or other heat-setting stage, or a cold-working stage that controllably plastically deforms the strands. The shaped structural strands cooperate to impart to the prosthesis its nominal shape and resilience. The textile strands cooperate to provide one or more layers of sheeting (40) that reduce permeability and thereby enhance the utility of the prosthesis as a vascular graft. An alternative embodiment prosthesis (132) includes elastically and plastically deformable structural strands (140), selectively plastically deformed by cold working, then three-dimensionally braided to form the prosthesis.
