Patent CA-2330890-A1 (CA)
Inventor: COUPAL ANDRE
IPC: F16K51/00
Filed: 2001-01-11
Abstract: A substantially sputtering-free low-profile low-restriction drain valve is used with a fluid reservoir having a drain opening. The drain valve comprises a valve body, a cap and at least one perforation-sealing member.      The valve body has a tubular shank installed in the drain opening and defining a fluid ingress, and a tubular head portion generally coaxial with the tubular shank and defining a chamber in communication with the fluid ingress and having a cross sectional area larger than a cross sectional area of the fluid ingress. The tubular head portion comprises an inner transverse wall extending across the chamber and comprising at least one fluid flow perforation, and a distal end opposite to the shank. The cap is movably assembled to the distal end of the tubular head portion between open and closed positions. This cap defines a fluid egress which, in the open position of the cap, is in communication with the perforation to permit draining of fluid from the reservoir. The perforation-sealing member is interposed between the cap and the tubular head portion and, in the closed position of the cap, seals the perforation to prevent draining of fluid from the reservoir. When the cap is in open position, fluid from the reservoir is drained through the ingress, chamber, perforation and egress. The perforation has a cross sectional area equal to or larger than a cross sectional area of the fluid ingress, while the egress has a cross sectional area equal to or larger than the cross sectional area of the perforation; this avoids leakage and a low restriction operation of the drain valve.

Title: Low complexity decision feedback sequence estimation
Inventor: JAVERBRING STEFAN
IPC: H03M13/41
Filed: 1999-08-17
Abstract: A Decision Feedback Sequence Estimator (DFSE) metric is determined by storing one or more tables of Decision Feedback Estimation (DFE) hypotheses in a memory, and then using values of the DFE hypotheses that are retrieved from storage to determine the DFSE metric. The DFE hypotheses may be precalculated and stored into the memory prior to performance of any retrieval operation. Alternatively, the table may start out empty, and the DFE hypotheses may be determined as needed for a particular DFSE  metric computation. The determined DFE metric may then be stored into a table for later retrieval if the metric is needed again. The DFE hypotheses may be stored into a single table or, to reduce memory requirements and computational complexity, may be stored into corresponding ones of plural tables. MLSE hypotheses, which are also used in the DFSE metric determination, may similarly be stored into one or more tables for later retrieval as needed.

Title: Sol-stop
Inventor: LAMARRE YVAN
IPC: A63C17/14
Filed: 2001-03-14
Abstract: Dans la pratique du sport du patin à roues alignées, on sait que la façon usuelle de freiner est de pousser contre le sol un sabot de freinage installé à l'arrière d'un des patins. Le patineur y parvient en levant le devant de son pied, pour ensuite pousser son talon vers l'avant sur le sol. Il est cependant très difficile pour celui-ci de garder le devant de son pied en position levée lorsqu'il exerce cette poussée. Son équilibre est également difficile à garder. Le freinage s'en trouve donc réduit. La présente invention consiste en un frein d'appoint, portable sur lequel un patineur peut s'y accouder et s'arrêter sans effort. L'appareil, conçu de telle sorte qu'il ne puisse être utilisé qu'en position « accroupie », jambes bien écartées, permet d'effectuer un freinage rapide et puissant sans grands risques de tomber.

Title: Immersed membrane module
Inventor: PEDERSEN STEVEN KRISTIAN
IPC: C02F1/44
Filed: 2001-05-18
Abstract: Elements of immersed, suction driven, ultrafiltration or microfiltration hollow fibre membranes have an upper header and a lower header with the membranes suspended between them. The elements do not include means for holding the headers in position relative to each other. A cassette is made by sliding a plurality of the elements into a frame to place them side by side. The frame restrains the elements in place but the restraint may be released to allow a selected element to be removed in a direction substantially parallel to its headers without disassembling the remainder of the module. The vertical location of cross bars which hold headers may be changed from time to time to maintain the membranes in a slightly slackened condition. The elements are narrow and spaced to promote penetration of the bubbles and tank water into the elements. Cassettes are placed back to back in pairs separated by permeate pipes. The connections between the permeate pipes and the cassettes release when an element is pulled out of the cassette and reseal when the element is replaced in the cassette.      The headers are made of an extrusion which may be cut to any desired length. Cassettes may be produce to a variety of desired sizes.

The system includes a method which begins when a request is received at the first gateway controller to establish a secure communication channel between the first user and the second user. Next, a secret key (408) is generated at the first gateway controller. A copy of the secret key is distributed to the first and second telephony adapters over previously established secure connections.  Finally, the secure communication channel is established (422) between the first user and the second user by encrypting and decrypting information using the secret key.

Title: Design of a soft contact lens based upon novel methods of corneal topographic analysis
Inventor: DAVIS BRETT A
IPC: G02C7/04
Filed: 2000-08-08
Abstract: A method is provided which is used to design soft contact lens via corneal topographic analysis. The topography of the cornea is matched to a corresponding topography of a soft contact lens. A  geometrical transformation which maps the corneal elevation onto the back surface of an unflexed soft contact lens is used to minimize errors induced by flexure of the lens. The mapping transformation takes into account the effects of flexure. As a result, the contact lens has a back surface with a curvature which matches the specific elevations of the cornea, while the front surface can be spherical or any desired symmetrical or asymmetrical shape.
