IPC: H04R3/00
Filed: 2001-09-07
Abstract: A method for equalizing output signals from a plurality of signal paths is disclosed. The method comprises steps of identifying a transfer function for each of signal paths, determining a filtering function for each signal path such that a product of the transfer function, and the filtering function is a selected function and applying the filtering function to the corresponding signal path, thereby correcting the transfer function of the signal path to the selected function to equalize the output signals from the signal paths. The step of applying the filtering function comprises steps of providing an equalization filter to the signal path and applying the filtering function to the equalization filter of its corresponding signal path, thereby equalizing output signals from the filter of the signal paths.

Patent CA-2359168-A1 (CA)
Inventor: GROVER WAYNE D
IPC: H04L69/40
Filed: 2001-10-16
Abstract: A method to increase the capacity efficiency of span-restorable mesh networking on sparse facility graphs. The new approach views the network as a "meta-mesh of chain sub-networks". This makes the prospect of WDM mesh networking more economically viable than with previous mesh-based design where the average nodal degree is low. The meta-mesh graph is a homeomorphism of the complete network in which edges are either direct spans or chains of degree-2 nodes. The main advantage is that loop-back type spare capacity is provided only for the working demands that originate or terminate in a chain, not for the entire flow that crosses chains. The latter "express" flows are entirely mesh-protected within the meta-mesh graph which is of higher average degree and hence efficiency for mesh restoration, than the network as a whole. Nodal equipment savings also arise from the grooming of express lightpaths onto the logical chain-bypass span. Only the meta-mesh nodes need optical cross-connect functionality. Other sites use OADMs and/or glassthroughs. The resultant designs comprise a special class of restorable network that is intermediate between pure span restoration and path restoration. Most of the efficiency of path restoration is achieved, but with a span restoration mechanism which is more localized and potentially faster and simpler than path restoration. The concept lends itself to implementation with OADMs having a passive waveband pass-through feature to support the logical chain bypass spans for express lightpaths.

Title: Parallel correlator architecture
Inventor: CARLSON BRENT R
IPC: G06F17/15
Filed: 2001-01-17
Abstract: The present invention relates to real time spectral analysis of wide-band sampled signals, in particular to a method and system for real time digital spectral analysis of wide-band sampled signals using parallel processing techniques. The center frequency of each received wide-band signal is shifted by a small fraction e of its bandwidth. After sampling and digitizing, the wide-band signals are de-multiplexed into N parallel sample streams for parallel processing. The sample streams are digitally FIR  filtered and sub-band signals are determined by decimating the sample streams by a factor of 2k.N;k = 0,1,..., wherein only every 2k.N th;k = 0,1,... sample is retained and the others are discarded. These sub-band signals may then be processed using various methods of spectral analysis such as cross-correlation, auto-correlation or phased array applications. Any finite-length FIR filter has a finite transition band. After decimation, the transition band outside sub-band boundaries will suffer aliasing, which causes signals to falsely appear as aliased signals within the sub-band. Shifting all spectral features in the wide-band spectrum with a frequency shift .epsilon. prevents false correlation of the aliased signals.

Filed: 2000-04-13
Abstract: An apparatus and method, utilized by a receiving node in a multicast for authenticating a message received from a transmitting node, uses tags to determine if the transmitting node is in the multicast. More particularly, a first tag received with the message is located and utilized to determine if the tranmsitting node is in the mulicast. The first tag includes data associated with at least one of the receiving node and the transmitting node.  A second tag then is generated if the transmitting node is determined to be in the multicast. Once generated, the second tag is transmitted with the message to a third node in the multicast. Among other things, the second tag includes data indicating that the receiving node is in the multicast.

Title: Method and apparatus for producing bulk quantities of nano-sized materials by electrothermal gun synthesis
Inventor: PETERSON DENNIS ROGER
IPC: C01F7/424
Filed: 2000-09-14
Abstract: A process for synthesizing nanosized powders utilizes a hybrid exploding wir e device containing a solid metal wire fuse in the bore of a tube that is open  at each end. The ends of the fuse are connected to electrodes on the ends of  the tube. The electrodes are designed to erode to maintain a heavy metal plasma. The bore may comprise a corresponding ceramic to be produced, and a microcrystalline powder of a corresponding ceramic may be retained within th e bore. An electrical discharge vaporizes and ionizes the fuse. The tube confines the radial expansion of the plasma such that the plasma exits from both ends of the tube where it reacts with a suitable gas to form nanoscale particles. In addition, the plasma gas ablates and vaporizes a portion of th e bore wall to contribute to the nanoceramic synthesis. Other alternatives include replacing the fuse with a thin conductive sheath or a consumable met al insert.
