Abstract: A method for electric discharge machining (EDM) with a ductile carbonaceous electrode, to automate the roughing, finishing and polishing operation on electrically conductive material. This EDM machining technique consists in using a ductile electrically conductive electrode made of carbon-polymer composite material. Prior to electric discharge machining, the electrode is made by heating uniformly a prescribed volume of said ductile electrode material, at a temperature close to the melting point temperature of the polymer matrix. The composite material is then molded into the desired electrode shape by pressing the soft material against a template, a mold model, a replicate of the workpiece or part of the workpiece. The formed electrode is then used to machine the desired shape and surface finish on the said workpiece using proper electric discharge machining techniques. When the dimensions and surface of the electrode are altered by wear, the same electrode can be rectified quickly and repetitively, by following the initial procedure of softening and pressing until the workpiece is completed.

Abstract: A Fiber-to-the-Home (FTTH) multi-media access system and method are provided in which voice, video and data signals are transported over a passive optical network (PON) between a central office location and a plurality of subscriber home network units (HNUs). Optical video distribution circuitry and telephony/data distribution circuitry at the central office location are included in the system and operate to send and receive CATV video, PBS video television, telephony and Packet data signals to and from the HNUs via the PON. Optical multiplexing/demultiplexing circuitry operating at the central office combines the video signals, which are operating at one optical wavelength, with the telephony/data signals, which are operating at a second, distinct optical wavelength. These combined optical signals are then transported over the PON  to the HNUs. The PON includes a plurality of distribution fibers coupled to a plurality of passive optical splitters, which are each coupled to a plurality of drop fibers that connect to the HNUs. The HNUs receive the combined optical signals, demultiplex and convert the optical signals into corresponding electrical signals, which are in turn coupled through the HNU to the video, data and telephony networks within the home. The HNUs also receive upstream electrical signals from devices within the home, multiplex and convert these electrical signals into upstream optical signals, and transmit these upstream optical signals to the central office.

Patent CA-2381125-A1 (CA)
Inventor: JACQUEMIN MARC G
IPC: C12N15/13
Filed: 2000-07-13
Abstract: The present invention comprises ligands and methods of manufacture thereof as well as pharmaceutical preparations including the ligands. The ligands may be human or humanized monoclonal antibodies and fragments, derivatives and homologs thereof. These may exhibit an unforeseen "plateau effect", i.e. the achievement of only a partial inactivation of a factor involved in hemostasis, in particular in the coagulation cascade, either individually or in combination even in molar excess. The ligands may bind to a factor or a complex of factors resulting in only partially impairing the function of a physiologically functional site of the said factor or factor complex even in molar excess. This makes the ligands particularly suitable for treating coagulation disorders and resulting thrombotic pathologic conditions while minimizing the risk of bleeding. Particularly useful is a property of ligands in accordance with the present invention to allow some physiological function of the affected site even when the ligand is in molar excess. The ligands may be anti-factor VIII antibodies or antibodies against a factor VIII complex, in particular human or human hybrid monoclonal antibodies which bind to factor VIII or a factor VIII complex and at least partially inhibit the activity of factor VIII.

Title: Method and apparatus for a four-way hash table
Inventor: BROWN DAVID A
IPC: H04L12/56
Filed: 2000-09-18
Abstract: A number of hash tables are accessed concurrently with a different computed index for each hash table. Each index identifies a location in one of the hash tables at which a forwarding entry may be stored. To search for a forwarding entry, the locations identified by the indices computed by performing a hash function on a search key are searched to a match for the search key. To insert a forwarding entry if single cycle inserting is not required and all the locations identified by the indices computed by performing a hash function on an insert key are used then the data base is reordered so that the forwarding entry can be inserted at one of the locations identified by one of the computed indices for the inset key. If single cycle insertion is required and all the locations identified by the computed indices are used, one of the locations identified by one of the computed indices for the insert key is randomly overwritten by the forwarding entry.
