Patent CA-2363796-A1 (CA)
Title: A system, method and article of manufacture for an electronic commerce interface to the government
Inventor: BOX RICHARD T
IPC: G06Q20/14
Filed: 2000-02-25
Abstract: A system is disclosed that provides access to the Internet, particularly by businesses, to transact business electronically to comply with various statutory requirements to report taxable revenues, new hires and taxes withheld on behalf of their employees regularly to the government. Today, businesses fulfill these requirements by physically submitting forms by mail  or in person to a government agency, a time consuming process that, accordin g to analysts, costs them over $600 billion annually. There is a business need  and a market opportunity for an electronic conduit for business to governmen t transactions. The new system is Internet based and provides a suite of transactional and information based services to businesses. The service is offered as a subscription service in selected states where the number of businesses is sufficient to ensure profitable revenues at the anticipated levels of market penetration.

Patent CA-2369396-A1 (CA)
Inventor: LAM CEDRIC F
IPC: H04Q11/00
Filed: 2002-01-25
Abstract: A four-port wavelength-selective crossbar switch generates an add/drop wavelength signal from a wave division multiplexed (WDM) signal using a plurality of double-sided reflectors that selectively reflects a selected wavelength channel signal of the WDM signal through optical circulators to provide low crosstalk between the dropped and added wavelength signals. The switch also reduces the number of WDM MUX-DEMUX required to one half that compared to a traditional approach. Furthermore, the switch can be designed to be wavelength cyclic with individual free spectral ranges that can be independently set to either through or add/drop states.
Patent CA-2372344-A1 (CA)
Title: Planar lightwave wavelength blocker
Inventor: DOERR CHRISTOPHER
IPC: H04B10/291
Filed: 2002-02-18
Abstract: A method and apparatus are disclosed for filtering an input wavelength division multiplexed (WDM) signal comprised of N wavelength channels. The disclosed wavelength blocker includes a demultiplexer for producing a plurality of demultiplexed output signals from the input WDM signal and a multiplexer for producing an output WDM signal. In addition, a shutter array selectively passes each of the N  wavelength channels using a plurality of shutters. The demultiplexer is coupled to the multiplexer using a plurality of waveguides having approximately equal length, in order to reduce multipath interference. The shutters may be embodied, for example, as Mach-Zehnder switches, electro-absorption modulators or Y-branch switches. Each of the N wavelength channels in the incoming signal are selectively passed or blocked using a thermo-optic or electro-optic control signal to control the state of the corresponding shutter. Crosstalk among the various N channels can be reduced using dilation techniques that position two shutters in series, especially where the shutters are thermo-optic Mach-Zehnder switches. Wavelength-selective cross connects and wavelength add-drop multiplexers are also disclosed that employ the novel wavelength blockers.

Title: Method and apparatus for recording an optical grating in a photosensitive medium
Inventor: CHOTARD HELENE
IPC: G02B6/02
Filed: 2002-03-18
Abstract: A method and an apparatus for recording optical gratings in a photosensitive medium are provided. The invention uses a phase mask in combination with a scanning of the recording light beam. The phase mask, or alternatively the photosensitive medium, is translated along a direction parallel to the scanning of the light beam, so that the period of the recorded grating may be focally adjusted. To ensure a proper recording efficiency over a large range, an appropriately selected wavefront curvature is provided in the light beam. The method of the invention is particularly advantageous for the recording of superimposed grating components in a photosensitive medium.

Title: Gel potting method for producing filtering hollow fibre membranes
Inventor: PEDERSEN STEVEN KRISTIAN
IPC: B01D63/02
Filed: 2001-05-02
Abstract: To pot membranes in a header, a dense, viscous liquid, suspension or, preferably, a thixotropic, water soluble gel (30), is placed in a header pan in space reserved for a permeate channel. A plurality of hollow fibre membranes (10) are collected together and their open ends are inserted into the gel. A fixing liquid, typically a resin (14), is placed over the gel (30).  The fixing liquid (14) surrounds each membrane (10) and then solidifies, simultaneously sealing the outer surfaces of the membranes and forming a plug in the opening of the header to complete the permeate channel. After the fixing liquid has solidified, the gel (30) is removed by various means. The space initially occupied by the gel becomes part of the permeate channel after the gel is removed. In one embodiment, membranes are grouped by a cushioning adhesive which later surrounds the membranes where they exit the completed header.

Abstract: Selon l'invention, des transferts de fonds, dirigés par des clients et effectués sur l'Internet, comprennent une combinaison de systèmes et de réseaux, notamment l'Internet, le courrier électronique et le système de chambres de compensation automatisées. Un système hôte constitué par un service de transferts de fonds gère des demandes de transferts de fonds, faites par des expéditeurs, et gère en outre les réponses de réclamations de fonds, faites par les destinataires. Ce système hôte permet qu'un expéditeur démarre un transfert de fonds en spécifiant le montant du transfert et les informations permettant d'entrer en contact avec le destinataire, sans avoir à préciser le numéro de compte du destinataire qui doit recevoir les fonds, car, c'est le système hôte qui va entrer en contact avec le destinataire et informer celui-ci de la disponibilité des fonds, le destinataire pouvant alors fournir les informations nécessaires relatives au compte cible, aux fins d'achèvement du transfert de fonds. La chambre de compensation automatisée est utilisée pour exécuter le transfert de fonds, le système hôte fournissant les instructions permettant à la chambre de compensation d'entrer dans son institution financière à l'aide des informations relatives aux comptes, reçues séparément de l'expéditeur et du destinataire. Le risque de crédit, associé aux entrées de la chambre de compensation d'origine, est réduit par l'utilisation du système de point de vente, lequel permet de vérifier si le compte de l'expéditeur dispose de fonds suffisants, par comparaison entre le solde de clôture établi le jour où le transfert de fonds est demandé, et le montant du transfert. Toute fraude du fait de l'expéditeur est pratiquement supprimée par comparaison entre un solde fourni par l'expéditeur (ou numéro/montants du chèque) et un solde de compte, acquis par des moyens automatiques, tels que le système de point de vente ou le réseau MTA.

Abstract: A suction brush assembly of a vacuum cleaner has a housing having a suction duct to provide a suction passage for dust, a rotation roller having a plurality of ribs formed at an outer circumference, a wheel disposed at the housing, and a power transmission unit to rotate the rotation member by exerting a rotation force of the wheel to the rotation member when the wheel is rotated. The wheel and the rotation member are rotated in directions opposite to each other by the power transmission unit. When a user wants to clean fabrics such as bedclothes or a carpet, the effect of hitting of the ribs can be firmly secured due to the rotation of the rotation rollers. Therefore, the effect of removing dust remarkably increases.

Title: School bus door/service brake interlock retrofit system
Inventor: EBERLING CHARLES E
IPC: B60T17/18
Filed: 2001-07-19
Abstract: A bus door/service brake interlock system having a warning system is provided to inform a driver that the service brake pressure is insufficient or not being applied at all, as well as indicating if a system malfunction occurs, precluding a service brake application. The system is based on a sequential operation of the driver activating the caution lights and opening the door.  Once these events have occurred, the autobrake system (70) including an alarm (90) is activated. On the other hand, applying the park brake (56) deactivates the autobrake system. The autobrake assembly energizes a solenoid (76) that receives regulated pressure from a pressure reducing valve (72). This pressure is supplied to one side of a double check valve (78), while the other side receives a delivery from the foot valve (24) to assure delivery for normal service braking.
