Patent CA-2390525-C (CA)
Title: Launderable, leak-proof, breathable fabric and articles made therefrom
Inventor: SHAO YUN
IPC: A41D31/00
Filed: 2000-11-10
Granted: 2003-11-04
Abstract: A launderable and reusable, leak-proof, breathable fabric and, more specifically, a composite fabric comprised of a liquid absorptive layer and a liquid impervious but vapour permeable layer. Such fabric is useful in drawi ng fluids, such as bodily fluids, away from a source, such as the body, and retaining them within the absorptive layer while evaporation thereof takes place though the vapour permeable layer. This material consists of two juxtaposed layers. The inner layer has the characteristic of being liquid permeable so as to allow the body fluids to flow into it and be absorbed. Th e outer layer has the characteristic of being liquid impermeable but air or vapour permeable, so that the liquid absorbed in the inner layer does not strike through the outer layer. Because the body fluids can flow into the inner layer, the wearer does not experience a clammy feeling from the materi al next to the skin. The breathability of the outer layer also reduces wet feeling and will in fact allow some evaporation of liquid collected in the inner layer. The material provides the functions of absorbing or drawing min or quantities of bodily fluids away from the wearer yet is sufficiently thin an d comfortable to be inconspicuous. In addition, the resulting fabric material is capable of being laundered, isstain resistant, and substantially retains its other properties after numerous cycles of use and washing. In general, the material comprises a fabric made from absorbent acetate fibers and possibly one or more other fibers such as polyester or nylon, to which is laminated o r adhered a liquid imperviousness but vapour permeable microporous polyurethan e film, to result in an substantially integral fabric material from which articles can be manufactured which can take advantage of the material's absorbent, launderable/reusable, leak-proof and breathable nature.
Patent CA-2391507-C (CA)
Title: Immunomodulatory compositions containing an immunostimulatory sequence linked to antigen and methods of use thereof
Inventor: TUCK STEPHEN
IPC: A61P37/00
Filed: 2000-11-15
Granted: 2010-08-10
Abstract: The invention provides classes of immunomodulatory compositions which comprise an average of one or more immunostimulatory sequence (ISS) containing polynucleotide conjugated, or attached, to antigen. The extent of conjugation affects immunomodulatory properties, such as extent of antigen-specific antibody formation, including Th1-associated antibody formation, and thus these various conjugate classes are useful for modulating the type and extent of immune response. The invention also includes methods of modulating an immune response using these compositions.

Patent CA-2403293-C (CA)
Inventor: CARTER THURMAN B
IPC: E21B33/1295
Filed: 2001-04-05
Granted: 2006-07-25
Abstract: The invention provides an apparatus (300, 400) for actuating a downhole tool (700) by utilizing a pressure differential created by fluid flowing through a restriction in a conduit (315). The conduit is in communication with a pressure sensing line (400) that is selectively exposable to areas of near the restriction in the conduit (316, 317) having different pressures. By exposing the pressure sensing line to a portion of the conduit having a predetermined pressure therein, the pressure sensing line causes actuation of a hydraulic tool therebelow. The apparatus is of particular use for a single trip sidetrack system in combination with an MWD-tool, a whipstock, and an anchor packer without a bypass valve.

Granted: 2006-06-06
Abstract: A method and apparatus for improved cutting of an object is provided. The object can take the form of many different structures including thin formations that require cutting precision, support, and dimensional control. In accordance with one example embodiment of the present invention, the method of cutting a member uses a laser and begins with the step of providing a template removably adhered to the member. The laser then projects through the template, without intersecting with the template, to cut the member and manufacture the desired formation. The laser does not intersect with, and therefore does not cut, the template structure and cause excess laser cutting dust.

Title: Credit report retrieval system including voice-based interface
Inventor: DANAHER JOHN THOMAS
IPC: H04M3/493
Filed: 2003-04-01
Granted: 2011-09-13
Abstract: Methods, apparatuses and systems providing a voice-based interface to credit report retrieval systems allowing users to order credit report data using a telephone or similar device. The present invention provides novel functionality and process flows directed to handling a request from a caller for a credit report, while providing a secure and easy-to-use voice interface. In one embodiment, the functionality associated with the present invention allows a customer to access his/her credit score via a telephone or other suitable voice-based device, and have a credit report mailed to his/her address. The use of a voice interface, instead of a traditional graphical user interface associated with web-based services accessible over a client computer, marks a departure from traditional credit reporting product channels and provides an opportunity to access a large market of consumers who do not regularly access the Internet. In one embodiment, the present invention further provides a novel authentication methodology, especially adapted to telephone network devices and other interfaces having limited text entry capabilities, that minimizes the opportunity for malicious users to glean authenticating information; i.e, personal information presumably known to an individual that may be used to authenticate identity.
