Patent CA-2231530-C (CA)
Title: Grating-assisted fused fiber filter
Inventor: LAUZON JOCELYN
IPC: G02B6/34
Filed: 1998-04-14
Granted: 2001-08-07
Abstract: A fused fiber filter coupler is disclosed characterized in that a long period grating is written in at least a portion of the waist of the coupler. The two fibers which make up the coupler have respective propagation constants .beta.fiber1 and .beta.fiber2 which are different and both fibers are singlemode at the wavelength of operation. In order for an efficient grating to be written in the waist of the coupler, the coupler must be photosensitive in at least a region of the waist. Since the propagation constant is a function of the wavelength and the period of the grating is given by the expression ~ = 2.pi.(.beta.fiber1 -.beta.fiber2), the filter may be tuned to a particular wavelength by adjusting the period of the grating. The filter so constructed acts in transmission and can discriminate wavelengths of the order of 1 nm. The filter is particularly useful in wavelength-rich optical communications networks to extract a particular wavelength from a signal or to add a particular wavelength to a signal (i.e. multiplexing and demultiplexing).

Abstract: A method for lining a clutch plate is described.      Arcuate segments are formed from a sheet of friction material.      These segments are applied at spaced, adjacent positions from different radial directions upon a side of an annular clutch plate. This forms lubrication channels. The segments are then bonded to the plate. The method limits waste of friction material and enables the lubrication channels to be formed without preforming or otherwise shaping the applied friction material.

Title: Technique for limiting network congestion
Inventor: ODLYZKO ANDREW M
IPC: H04L12/24
Filed: 1998-08-07
Granted: 2004-04-06
Abstract: A technique for regulation of packet switched network traffic through usage-sensitive pricing is disclosed. The network is partitioned into logical channels and a user incurs a cost for use of each of the logical channels.  The logical channels differ primarily with respect to the cost to the user. Each user will select a channel that provides the subjectively optimal balance of cost and perceived quality of service, with the lowest cost channels presumably carrying the most traffic (and hence being more congested) and the highest cost channel accordingly carrying the least traffic (and hence being the least congested). Network traffic will accordingly be distributed between channels and each user will incur predictable charges without being precluded from seeking a higher quality of service when desired.

Granted: 2007-03-06
Abstract: A method for enhancing the expression of a selected gene in an organism whil e avoiding or reducing co-suppression involves the synthesis of a DNA which is altered in nucleotide sequence and is capable of expression of a protein, ideally identical to that of a protein already expressed by a DNA already present in the organism. This method ensures that sequence similarity between the two genes is reduced enough to eliminate the phenomenon of co-suppression, allowing th e over-expression of a specific protein. The method is particularly suitable in plants.

Title: Flexible integrated circuit package
Inventor: HARRIS MARK ROY
IPC: H05K3/30
Filed: 1998-11-03
Granted: 2004-06-29
Abstract: A flexible integrated circuit package for mounting on a substrate is disclosed. The package consists of a tape film having layers of dielectric and conductive material, a semiconductor die and an array of conductive leads. A molded body covers the die, and absorbs the majority of the pressure applied when compressing the package between a heatsink and a printed-circuit board (PCB). Rigid removable support material surrounds the molded body to keep the package flat while it is being mounted to the PCB. The support material is removed after soldering of the package to the PCB. The invention permits the package to be tightly compressed between a heatsink and a substrate without causing degradation of the conductive connections. Reliability of the connections is further increased since the tape film is flexible enough to accommodate bending of the substrate to which the package is connected.

Abstract: Calls may be distributed and load balancing maintained for a distributed automatic call distributor (ACD) system by simulating a central FIFO queue at the central routing point of the system. The simulated FIFO queue either requires that the number of calls in queue and the oldest call waiting time of calls at each automatic call distributor be periodically provided to the central routing point or event-based data be provided on each call answered in the system or not routed by the central routing point. Deviations from FIFO  order of service recorded at the simulated FIFO queue may signal the need for requeuing a call at another automatic call distributor. With additional information on agents available, the call removal rate may be estimated. Also, delay estimates may be updated based on comparing actual and estimated delays over time. The routing point may be updated with traffic data through, for example, a known telemarketing operations performance management system (TOPMS) or directly from the automatic call distributors via the toll telecommunications network.

Abstract: A method for evaluating the coherence of environmental measurements of a given geological medium or field using well logging data is disclosed. A  series of N geological parameters are each measured at a series of reference points found in reference wells within this medium. Each reference point is at a different depth and has known lithological characteristics, and the N measurements form a reference observation (X i) corresponding to that point. The same N parameters are measured at application points found in one or more application wells, at depths identical to those of the reference points, forming an application observation (x) for each application point. A neighbouring domain (D i) and acceptance class are defined for each reference observation (X i). Each application observation (x) is then compared with all of reference observations (X i) using a nearest-neighbour algorithm to determine the degree of membership of the application observation in each reference observation's acceptance class. This degree of membership is then used to predict or estimate the lithological characteristics for each application point.

Title: Success-to-the top class of service routing
Inventor: ASH GERALD RICHARD
IPC: H04L12/56
Filed: 2000-02-24
Granted: 2004-09-28
Abstract: An originating switch (110) in a packet-based telecommunications network (100) routes calls to a terminating switch using the combination of Success-to-the Top (STT) and Class-of Service criteria. In routing a call to the terminating switch, the originating switch 110 checks for available bandwidth for the class of service of the call on the direct path (116) between switches. If the path has available bandwidth, the originating switch routes on the direct path. Otherwise , the originating switch searches for the most recently successful one of a plurality the via switches (1181-118") linking the originating and terminating switches to determine whether that via switch can successfully route the call to the terminating switch. If the most recently successful one of the via switches possesses available bandwidth to route the call in accordance with its class of service, the originating switch 110 selects that via switch to route the call. Otherwise, if the most-recently successful via switch can not route the call, the originating switch 110 searches for a next successful via switch. If none of the via switches 118 1-118n can successfully route the call in accordance with its class of service, the originating switch will either attempt a route advance or crank back the call.
