Patent CA-2426111-A1 (CA)
Inventor: JOO PAN-YUH
IPC: H04J3/06
Filed: 2003-04-17
Abstract: Disclosed herein is a ranging method for a mobile communication system based on an OFDMA (Orthogonal Frequency Division Multiple Access) scheme. In the communication system for classifying a ranging procedure between a transmission side and reception sides into an initial ranging process, a bandwidth request ranging process, and a periodic ranging process, the ranging method includes the steps of determining the number of initial RCs(ranging codes) for the initial ranging process, the number of bandwidth request RCs for the bandwidth request ranging process, and. the number of periodic RCs for the periodic ranging process, determining a backoff value of the periodic RCs according to the number of the periodic RCs, and sending the initial RCs, the bandwidth request RCs, the periodic RCs, and the backoff value of the periodic RCs to the reception sides.
Patent CA-2428393-A1 (CA)
Inventor: COCKBURN BRUCE F
IPC: G06F17/14
Filed: 2003-05-09
Abstract: Compact and efficient hardware architectures for implementing lifting-based DWTs, including 1-D and 2-D versions of recursive and dual scan architectures. The 1-D recursive architecture exploits interdependencies among the wavelet coefficients by interleaving, on alternate clock cycles using the same data path hardware, the calculation of higher order coefficients along with that of the first-stage coefficients. The resulting hardware utilization exceeds 90% in the typical case of a 5-stage 1-D DWT operating on 1024 samples. The 1-D dual scan architecture achieves 100% datapath hardware utilization by processing two independent data streams together using shared functional blocks. The 2-D  recursive architecture is roughly 25% faster than conventional implementations, and it requires a buffer that stores only a few rows of the data array instead of a fixed fraction (typically 25% or more) of the entire array. The 2-D dual scan architecture processes the column and row transforms simultaneously, and the memory buffer size is comparable to existing architectures. The recursive and dual scan architectures can be readily extended to the N-D case.

Title: Purified active hcv ns2/3 protease
Inventor: LAMARRE DANIEL
IPC: C12N7/01
Filed: 2001-12-13
Abstract: A method for producing a refolded, inactive form of recombinantly produced NS2/3 protease which comprises the steps of: a) purifying the protease from inclusion bodies in the presence of a chaotropic agent; and b) refolding the purified protease by contacting it with a reducing agent and lauryldiethylamine oxide (LDAO) in the presence of reduced concentration of chaotropic agent or polar additive. The invention further comprises a method for activating this refolded inactive NS2/3 protease by adding an activation detergent. This method produces large amounts of the active NS2/3 protease to allow small molecules and ligands to be screened as potential inhibitors of NS2/3 protease, which may be useful as therapeutic agents against HCV.

Title: Wand assembly for a domestic appliance
Inventor: EVANS NICHOLAS ALEXANDER
IPC: F16L21/00
Filed: 2002-02-27
Abstract: A wand for a domestic appliance (e.g. vacuum cleaner) comprises a plurality of tubes (10, 20, 30, 40) which are dimensioned to telescope inside one another.  Each tube (10, 20, 30, 40) is associated with a securing mechanism (15, 25, 35) for securing the tube in an extended position with respect to another of the tubes. Adjacent securing mechanisms (15, 25, 35) are positioned on their respective tubes such that, when the tubes are retracted, one securing mechanism presses against another to release the other securing mechanism.  Thus, a user does not need to separately operate each securing mechanism (15, 25, 35) when extending the wand. Also, the tubes automatically secure themselves in an extended position with respect to one another. A hook (550) on the widest tube (10') cooperates with a collar (610) on the narrowest tube (40') to retain the tubes in a stored position.

Patent CA-2448600-A1 (CA)
Title: Insulated casing and tubing hangers
Inventor: DEMNY ALBERT
IPC: E21B33/04
Filed: 2003-11-07
Abstract: The present invention provides a hanger for either casing or tubing strings that electrically insulates the internal suspension system of the hanger from the hanger's external seal. Electrical power is typically transferred through a hanger via the internal suspension system. If electrical umbilicals are used, connecting devices may be located within the internal suspension system for connecting an upper and lower umbilical and transferring power through the hanger. If a rigid tubular conductor is used, the suspension system may be ported to allow the passage of electrical feedthroughs or, in the case of tubing hangers, the tubing itself may be charged with electrical power. By insulating the suspension system from the external seal, potential electrical hazards are eliminated.

Abstract: A membrane electrolysis cell comprising an anodic compartment and a cathodic compartment is described, wherein at least one of the two compartments contains an electrode fed with gas and a porous planar element is interposed between the membrane and the gas-fed electrode. A flow of chemically aggressive electrolyte crosses the porous planar element downwards under the effect of the gravity force. The planar element consists in a plastic elemen t withstanding the aggressive operative conditions: The use of perfluorinated plastics such as ECTFE, PTEFE, FEP, PFA is preferred, even though they are strongly hydrophobic. When the gas-fed electrode is a cathode and the gas contains oxygen, the gas crosses the cathodic compartment upwardly so as to minimise the risk of hydrogen build up. The cell equipped with the oxygen cathode is particularly advantageous for the sodium chloride electrolysis.</ SDOAB>
