Title: Method and system for allocating and controlling labels in multi-protocol label switched networks
Inventor: MARK BARRY DING KEN
IPC: H04Q11/00
Filed: 2002-05-13
Abstract: A method and system for allocating and controlling a hierarchy of labels in an MPLS network is provided. The hierarchy of labels, inserted into MPLS packets, is introduced so as to correspond to the hierarchy of sub-flows within a data flow. The labels have the established dependency so that positions of labels in the hierarchy identify a sequence of processing the labels and functions associated with the labels.      The system for allocating and controlling the hierarchy of MPLS labels includes a first control plane mapper for releasing available labels, a first controller for assigning the released labels according to the hierarchy, means for transmitting the labels in the network, a second controller for detecting the labels, and a second control plane mapper for maintaining current label dependency within the hierarchy. If required, re-addressing of the hierarchy of labels may be performed to maintain flow-sub-flow association throughout two adjacent networks. In the preferred embodiments on the invention the method of allocating and controlling hierarchy of labels is applied to sub-flows within FA-LSP flows, and to multi-cast services in the network associated with a function of flooding and filtering data within a network node.

Title: Method for producing peroxydicarbonates and their use in the radical polymerization of monomers
Inventor: COZENS ROSS JAMES
IPC: C08K5/14
Filed: 2000-11-03
Abstract: A process for producing peroxydicarbonates comprising first reacting at least one inorganic peroxide with at least one alkali metal hydroxide to form at least one alkali metal peroxide. The at lest one alkali metal peroxide is added to a mixture of at least one haloformate, at least one dispersant and water. The mixture is homogenize during the entire reaction to form a peroxydicarbonate. The peroxydicarbonate is dispersed as small droplets of from 1 to 10 microns in size in the aqueous mixture.  The entire mixture is added to a polymerization reactor containing an ethylenically unsaturated monomer. The peroxydicarbonate functions as the free radical initiator to polymerize the monomer. The peroxydicarbonate is substantially free of organic solvents and plasticizers. The resulting polymers are of high quality.

Title: Monitoring and control of a froth flotation plant
Inventor: VAN OLST MARC
IPC: B03D1/02
Filed: 2000-11-23
Abstract: The invention uses machine-vision to improve the performance of a flotation operation to provide a substitute for conventional human vision and problem- solving abilities. The invention redirects the conventional approach of "characterising the froth" to "measuring the froth characteristics". The invention provides a method of monitoring and controlling a mineral mixture flow in a froth flotation cell of a flotation plant which includes the steps  of obtaining a series of digital images extracted of froth characteristics from a flotation cell. The digital images are transmitted to a computer for processing thereof into parameter signals of digital parameter froth characteristics. Control signals are produced in response to parameter signa ls received for causing required variations in froth characteristics in a flotation cell; and the froth characteristics in the flotation cell are controlled in response to the control signals so as to cause required variations in the froth characteristics in the cell.
Patent CA-2397390-A1 (CA)
Inventor: ROH MARK
IPC: H04B1/712
Filed: 2001-01-26
Abstract: A novel and improved method and apparatus for frequency tracking is described.  Two main sources of error that contribute to the frequency difference between locally generated carriers and those used to modulate received signals include frequency offset between the two timing sources and doppler effects due to relative movement between the sources. The present invention provides a tracking mechanism for removing the effects of error due to frequency offset as well as compensation for frequency error due to doppler in a plurality of multipath signals. Each finger (700a..700n) of a RAKE receiver utilizing the present invention will compute a frequency error for that finger. The weighted average of all of these frequency errors is calculated (710) and filtered (720) to provide a control signal for varying the frequency of IF and RF  frequency synthesizers, accounting for the common frequency offset seen at each finger. Additionally, each finger is equipped with a rotator (706a...706n) for providing frequency adjustment specific to that finger. The frequency of each finger is adjusted through feedback of the frequency error finger.

Title: Frequency divider
Inventor: HOLZLE JOSEF
IPC: H03K23/66
Filed: 2001-01-17
Abstract: The present invention relates to a frequency divider with an adjustable divider ratio (TV). Such circuits are subject to demands for ever higher clock frequencies. The present invention achieves this object by virtue of the fact that the circuit generates the output signal (OUT) in a blockwise manner and converts it into a sequential signal in a parallel-serial converter (MUX) on the output side and outputs it in a bitwise manner. As a result, the essential part of the frequency divider circuit can be operated with a slower frequency (C4) than the input frequency (C), which in turn enables higher input frequencies (C).

Abstract: A recirculating optical delay line (30) has a laser (32) controlled by wavelength control (33) so as to vary the wavelength of radiation over time to provide a first input (34) to an optical modulator (35). The modulator (35) modulates the intensity of the first input (34) with a pulsed electromagneti c frequency signal (36) to produce a pulsed modulated optical signal (39). The  signal (39) passes through an optical coupler (40) into a delay loop (41) having a delay fibre (44) arranged to delay the signal (39) for a predetermined duration. The wavelength control (33) is arranged to vary the first input (35) so as to ensure that overlapping pulses of the signal (39) in the delay loop (41) are at different wavelengths, thereby inhibiting optical  mixing effects between the overlapping pulses.

Title: Elastically retained hat and band
Inventor: NGAN JACKY
IPC: A42B1/22
Filed: 2003-04-11
Abstract: A hat includes an elasticized band that extends around the periphery of the hat's crown to retain the hat on the head of a wearer. The elasticity of the band in a longitudinal direction is not uniform across its width. Instead the elasticity is greater in one region proximate one edge of the band than it is in a second region proximate the opposite edge of the band. The band is comfortable for the wearer because it grips the wearer's head less tightly in the second region than in the first region. At the same time, the entire width of the band contributes to retaining the hat on wearer's head. The band can also be used to retain other garments on a wearer.

Patent CA-2429068-A1 (CA)
Inventor: ORENSTEIN MEIR
IPC: G02B26/08
Filed: 2001-11-14
Abstract: The invention is a waveguide structure (10) that includes two waveguides (90, 94) flanking a coupling region (92) whose effective refractive index is less than those of the waveguides. Outboard of the waveguides are bounding regions (88, 96) whose effective refractive indices decrease inwards adiabatically at the proximal and distal ends of the bounding regions. The waveguides are coupled optically by periodic perturbations of the waveguide geometry, or by reversible uniform or periodic perturbations of the effective refractive indices. In an optical switch matrix based on the waveguide structure, all the waveguides are straight and parallel. A second aspect of the invention is a directional coupler comprising mechanisms for reversibly and quasiperiodically perturbing the effective refractive indices of the waveguides. The respective envelope functions vary monotonically in opposite senses. Light propagating in one waveguide, in the direction in which that waveguide's envelope function increases, is coupled into the other waveguide.
