Patent CA-2530179-A1 (CA)
Title: In-line optical isolator
Inventor: TAKEUCHI YOSHIAKI
IPC: G02F1/09
Filed: 2004-06-23
Abstract: In conventional optical isolators, an optical signal is dispersed by polarization or the characteristics are varied by heat generation in a garnet crystal. According to the invention, the crystal optical axis (3c) of a rutile crystal (3) is oriented so that the separation directions of the ordinary ray O and the extraordinary ray E are perpendicular to the plane including the optical axes of optical fibers (10, 11). Furthermore, the focusing central optical axis (6c) of a focusing rod lens (6) is arranged parallel with optical axes of the optical fibers (10, 11) and at a substantially equal distance from the four rays, i.e. the ordinary ray O and the extraordinary ray E propagating along the optical axis of the optical fiber (10) and the ordinary ray O and the extraordinary ray E propagating along the optical axis of the optical fiber (11). An air gap (7) of about 200 [µm] is provided, as a heat insulating means, between the focusing rod lens (6) and a magnetized garnet crystal (8).

Title: Method and compositions for detection and enumeration of genetic variations
Inventor: DRESSMAN DEVIN
IPC: C12N/
Filed: 2004-06-09
Abstract: Many areas of biomedical research depend on the analysis of uncommon variations in individual genes or transcripts. Here we describe a method that can quantify such variation at a scale and ease heretofore unattainable. Each DNA molecule in a collection of such molecules is converted into a single particle to which thousands of copies of DNA identical in sequence to the original are bound. This population of beads then corresponds to a one-to-one representation of the starting DNA molecules. Variation within the original population of DNA molecules can then be simply assessed by counting fluorescently-labeled particles via flow cytometry. Millions of individual DNA  molecules can be assessed in this fashion with standard laboratory equipment.  Moreover, specific variants can be isolated by flow sorting and employed for further experimentation. This approach can be used for the identification and quantification of rare mutations as well as to study variations in gene sequences or transcripts in specific populations or tissues.

Patent CA-2539481-A1 (CA)
Inventor: TENCH MORGAN D
IPC: H01L21/768
Filed: 2004-09-24
Abstract: Bottom-up filling of fine Damascene trenches and vias in semiconductor chips is attained using a copper pyrophosphate electroplating bath with a single accelerating additive species present at low concentration (< 5 ~M). This bath is much easier to control than the acid copper sulfate bath, which employs a complicated additive system involving a minimum of two organic additives and chloride ion (as well as significant additive breakdown products).  Pyrophosphate copper deposits exhibit stable properties without annealing and are typically twice as hard as acid sulfate copper deposits, which facilitates chemical mechanical planarization. The mechanical properties and texture of the fine-grained pyrophosphate copper deposits are also much less substrate dependent, which minimizes the effects of variations and flaws in the barrier and seed layers. Attack of copper seed layers is minimized for the copper pyrophosphate bath, which operates in the pH 8 to 9 range. The resistivity of pyrophosphate and annealed acid sulfate copper deposits are substantially equivalent.

Patent CA-2542018-A1 (CA)
Inventor: TRAN NATHANIEL TUE
IPC: G01N33/60
Filed: 2004-01-28
Abstract: A novel analytical method involves labeling samples with different radioactive labeling agents, mixing and subjecting the mixture to any separation technique, and then differentially detecting and quantifying subcomponents from each sample for comparison. The novel technique exploits the differences in radiation energy or half-life between isotopes to make differential detection and quantification of labels possible. Detailed methods for differential detection and quantification are also described as well as the construction and application of hardware and software to enable and enhance such a process. This method is useful in applications that involve comparing differentially abundant molecules between two samples such as differential proteomics, phosphor-proteomics, glycomics, metabolomics, transcriptomics, genomics and diagnostic applications.

Title: Straw with leakage prevention
Inventor: STRIBLING ROBERT PATTON
IPC: A47G21/18
Filed: 2005-01-10
Abstract: A flexible check valve is introduced within a fluid path for leakage protection. The flexible check valve (300) can be a duckbill/crossbill valve comprising multiple flexible members (306) that restrict the flow of fluid in a tubular member. The flexible check valve is preferably used in conjunction with drinking straw (100) to prevent liquid from exiting a container such as drink box (200). Preferably, the flexible check valve is crossbill valve (400) that is attached using adapter (900). Liquid is designed to only flow through when an external compressive force (405) (e.g. users fingers or lips) is applied to the valve. When force is no longer applied to the valve section, the valve returns to its normally closed position and fluid is wholly or substantially prevented from exiting.

Title: Audio coding based on block grouping
Inventor: DAVIDSON GRANT ALLEN
IPC: G10L19/02
Filed: 2005-01-19
Abstract: Blocks of audio information are arranged in groups that share encoding control parameters to reduce the amount of side information needed to convey the control parameters in an encoded signal. The configuration of groups that reduces the distortion of the encoded audio information may be determined by any of several techniques that search for an optimal or near optimal solution.  The techniques include an exhaustive search, a fast optimal search and a greed merge, which allow the search technique to tradeoff the reduction in distortion against the bit rate of the encoded signal and/or the computational complexity of the search technique.

Title: System and method for tank pressure compensation
Inventor: VAITSES STEPHEN P
IPC: F02M25/08
Filed: 2005-02-16
Abstract: A supplemental fluid tank (10), preferably having two chambers (16, 18) each partially containing a fluid (22), fluid communicated intermediate a fuel tank (6) and vent (14) to reduce fuel vapor emissions, particularly for a boat.  More specifically, when fuel is used or cooled, pressure or volume, respectively, of the remaining fuel in the fuel tank (6) is reduced in prior art systems. Accordingly, air is drawn into the fuel tank (6) through the vent line (8) and becomes saturated with fuel (i.e., fuel vapor). Conversely, when fuel in the fuel tank (6) is warmed it expands and fuel vapor is forced out of the vent (14) into the environment. An exemplary embodiment reduces entry of air in through the vent (14) and escape of fuel vapor out of the vent (14) using two intermediate chambers (16, 18) in fluid communication with each other, each preferably having a non~-evaporative fluid (22) (e.g., oil), to provide volume/pressure compensation of the fuel in the fuel tank (6).

Title: Additive delivery laminate and packaging article comprising same
Inventor: HERNDON DAVID
IPC: B32B27/30
Filed: 2005-07-22
Abstract: An additive delivery laminate is suitable for packaging a food product which is cooked in the package, with an additive transferring from the laminate to the food product. The additive delivery laminate has a substrate and an additive delivery layer. The additive delivery layer contains a water-insoluble thermoplastic polymer, a polymer toughening agent, and additive granules containing a colorant, flavorant, and/or odorant. The polymer toughening agent is present in a blend with the water~insoluble thermoplastic polymer. Polyisobutylene is a preferred water-insoluble thermoplastic polymer, and hydrogenated wood rosin is a preferred polymer toughening agent. The polymer toughening agent decreases the tendency of the water-insoluble thermoplastic polymer to form legs or transfer to the food product upon stripping the laminate from the food product after cooking and transfer to the additive to the food product.
