Title: Convolutional interleaver with reduced memory requirements and address generator therefor
Inventor: HUANG ZHENG
IPC: H04L27/00
Filed: 1995-04-28
Granted: 2000-11-21
Abstract: A convolutional interleaver and addressing scheme are provided.  Up to B consecutive symbols containing errors can be interleaved such that they are separated from each other by at least N intervening symbols.  Memory, such as RAM, is configured to provide (B-1) cells of increasing size for storing symbols from a data stream.  A first one of the cells has M storage locations adapted to store M symbols.  Each successive one of the cells has M more storage locations than the immediately preceding cell for storing M more symbols than the immediately preceding cell, where M=N/B.  The cells are successively addressed to write a next symbol from the stream into a next write symbol location in a currently addressed cell and to read a symbol from the location of the currently addressed cell immediately following the next write symbol location.  The locations are accessed in a first revolving manner such that the last location in a cell is followed by the first location in that cell. The cells are addressed in a second revolving manner such that the (B-1)th cell is followed by the first cell, or vice versa.  An intervening transfer stage can be provided between the (B-1)th  cell and the first cell to directly transfer the next symbol to the interleaver output.  Each consecutive symbol from the stream is written into a next consecutive one of the cells.  A deinterleaver is provided having the same structure.

Abstract: An ATM inverse multiplexing cell-based system for reducing error-multiplication due to error events in the transmitted cell stream, which includes a first IMA assembly having an input coupled to an incoming cell stream from a first ATM layer device, a second IMA assembly having an output coupled to a second ATM layer device, a plurality of links coupling the first IMA assembly to the second IMA assembly.  The first IMA assembly includes a multiplexer for multiplexing the incoming cell stream onto the plurality of links and for inserting onto the links framing cells in the form of "st" cells in place of idle cells and "S" cells to mark divisions in each channel corresponding to a given number of cells or a given time interval between successive "S" cells.  An encoder encodes and inserts cell location information of both control cells and payload cells for a window of time into the past for each link into the framing cells.  The second IMA assembly includes a plurality of link buffers for receiving cells transmitted along respective ones of links.  A demultiplexer demultiplexes cells on the link buffers by aligning "S" cells on the link buffers and releasing payload cells so as to keep the link buffers partially filled as much of the time as possible if required for CDV smoothing.  A decoder extracts and decodes location information from the framing cells to identify errored or missing cells and to mark the location of those cells.  A discriminator distinguishes between errors in a header and errors in a payload of an errored cell and flushes all cells in the same frame on each link from the link buffers upon failure to identify an "unknown" cell before encountering buffer overflow or upon being blocked by another unresolved error.

Abstract: A blade is locked into groove in the periphery of a turbo-machine rotor by forming mating notches in opposing faces of the blade root and groove so as to form a blind hole. At assembly, a slotted radial pin is installed into the blind hole so as to prevent axial motion of the blade root. The pin is rotated so as to align its slot with a slot formed along the length of the rotor groove. A retaining strip is slid into the rotor groove slot so that it extends through the slot in the radial pin, with a pre--bent end of the strip resting against one face of the rotor. A tab formed on the other end of the strip is bent against another face of the rotor so as to lock the retaining strip in place. At dis-assembly, one of the retaining strip tabs is unbent and the retaining strip slid out. The pin is then extracted, thereby allowing the blade to be removed.

Abstract: In order to manufacture microstructures by the LIGA process, plastic layers are deeply irradiated across the image-area with X-ray radiation.  The areas of the plastic layers that have been rendered soluble or have remained soluble are removed selectively by  means of a developer.  Known plastics require a considerable outlay for irradiation.            In the process according to the present invention, photo-hardened epoxy lacquers are used; these require considerably shorter irradiation time compared to known plastics.  The microstructures can have a larger aspect ratio and can be developed without any faults even at greater structure depths.  The structure precision that is achieved is in the sub-micrometer range.            The process makes it possible to manufacture deep microstructures of very good quality, and to do so economically and with reduced irradiation outlay.
