Title: Image tessellation for region-specific coefficient access
Inventor: WHEELER FREDERICK WILSON
IPC: H04N7/30
Filed: 2002-11-07
Abstract: The present technique addressably handles image data (402), which is decomposed and tessellated into a plurality of tessellated sub-band blocks (430, 474, 516).  The tessellated sub-band blocks (430, 474, 516) may be addressed by an array of indices, which identify specific data blocks of the image data (402) by decomposition level and spatial coordinates of the tessellated sub-band blocks (430, 474, 516). Accordingly, a desired region (604, 672, 700) of the image data (402) at multiple resolutions can be identified and individually handled for storage, transmission, retrieval, and display. The desired region (604, 672, 700) also can be reference marked based on the array of indices.
Patent CA-2413029-A1 (CA)
Inventor: HICKS PETER N
IPC: H04L12/56
Filed: 2001-06-13
Abstract: A method and system for managing the routing of traffic within a network develops a topological address space map of the network to enable a "best route" selection process. The network is comprised of a backbone connected to a plurality of peering partners. Points on the network monitor traffic flows.  A central facility analyzes the traffic and routes within the network and performs intelligent routing management. Intelligent routing management ensures that traffic is properly routed through preferred routes on the network and avoids inefficient routing. Intelligent routing management also selects new routes to be injected into the network in order to further improve the accuracy of the address space map of the network. Intelligent routing management ensures that bandwidth is requested and delivered topologically closely to peering partner networks, and that traffic is carried by the backbone for long haul data distribution in both directions.

IPC: E03B5/02
Filed: 2001-08-17
Abstract: A pressure maintenance assembly for a domestic water well system. The assembly comprises a pressure maintenance valve having an inlet side and an outlet side, a pressure tank in fluidic communication with the outlet side, and a calibrated bypass. When the valve is closed, the calibrated bypass provides fluidic communication between the inlet side and the outlet side. The size of the calibrated bypass and the pressure tank are adapted and constructed to permit a flow rate between the inlet side and the outlet side that will fill the pressure tank in an time interval less than twice the time required to pump a volume of water that will dissipate heat generated by the pump when it is turned on.

Patent CA-2429920-A1 (CA)
Inventor: CASTELLUZZO RENEE
IPC: G06Q20/34
Filed: 2003-05-28
Abstract: A store or other entity distributes checks that designate a value for a consumer discount to be received toward the purchase of goods and/or services. The document or instrument within which the discount is indicated is actually a check that may be processed in accordance with the normal processing and routing of any other check that a business may receive in exchange for goods and/or services.        Advantageously, separate processing above and beyond that which is normally provided for normal check processing is not required. The check is drawn for a nominal amount and is usually substantially less than the value of the discount that is received by the consumer. Banks will still process the check for the nominal check value notwithstanding the fact that the actual processing fees incurred may be equivalent to the value of the check. The check may be made payable to the business entity and the bank statement may be useful in determining consumer feedback information.

Inventor: DEPELTEAU ROBERT
IPC: B60R1/08
Filed: 2003-09-26
Abstract: The invention provides an increased field of vision. By having a flat surface, and a curved edge, this type of mirror allows the driver to see into what would normally be the blind spot, thus effectively eliminating the blind spot. The flat surface allows the driver to see a non distorted view of the side of the truck, where it is important to have a clear view, especially when backing up. And the curved edge allows the driver to see the wider picture where a blind spot would normally be without having to look at another mirror.

Title: Anaerobic digester
Inventor: BAUMGARTNER JOHN W
IPC: C02F3/28
Filed: 2004-02-27
Abstract: An anaerobic digester and a method for treating organic waste and recovering a usable quality methane gas. A first cover of gas permeable material conducive to bacterial colonization covers the surface of a slurry of organic waste material in a containment vessel. The permeable cover acts as a media to support and encourage the growth of methanogenic bacteria. Gas collection apparatus is installed on the first cover. A second cover of gas impermeable material is installed over the gas collection apparatus. A gas collection space is formed between the two covers. Edges of the first and second covers are closed to inhibit the escape of gas from the gas collection space. Biogas produced as a result of anaerobic digestion activity permeates the gas permeable cover and enters the collection space. From the collection space the gas is drawn into the gas collection apparatus which can, for example, be comprised of a network of perforated ducts connected to a blower that draws gas out of the ducts for delivery to a storage or usage location.

Filed: 2003-01-22
Abstract: L'invention concerne un antigène de surface par voie des muqueuses servant à favoriser une augmentation de la réponse immunitaire contre les antigènes co-administrés dans les formulations décrites dans cette invention. Ces nouvelles formulations sont obtenues à partir de la double utilisation de l'antigène de surface comme agent immunostimulateur et à la fois comme agent antigène vaccinal. Ainsi, il est possible d'obtenir des formulations multiples de l'antigène de surface de l'hépatite B et des antigène hétérologues, avec des niveaux d'immunogénicité semblables à ceux obtenus après administration parentérale et avec une économie de composants capable de rendre inutile l'utilisation d'adjuvants nasaux, ce qui fait des antigènes des éléments capables de favoriser la croissance de la réponse immunitaire face à d'autres antigènes co-administrés. Cette nouvelle utilisation de l'antigène de surface du virus de l'hépatite B et les formulations antigéniques obtenues trouvent une application dans l'industrie pharmaceutique sous forme de formulations vaccinales préventives ou thérapeutiques.
