Patent CA-2328469-A1 (CA)
Inventor: FREDRIK OVESJO
IPC: H04J13/18
Filed: 1999-05-07
Abstract: Des ensembles de codes multiples sont introduits dans la liaison descendante d'un système CDMA pour augmenter le nombre de connexions dans chaque cellule. Les codes sont ensuite affectés à différents utilisateurs avec prise en compte de l'interférence entre eux. L'interférence dépend des gains d'antenne, des puissances de transmission utilisées et des codes entre les corrélations croisées. L'estimation de ces paramètres permet de réduire l'interférence dans le procédé d'affectation de code. L'affectation de codes et d'ensembles de codes à des zones géographiques à l'intérieur d'une cellule pouvant changer dans le temps, le transfert de code est assuré.
Patent CA-2330759-A1 (CA)
Inventor: BOWER RANDY KRISTOPHER
IPC: G01N33/48
Filed: 2001-01-11
Abstract: The invention is a method for detecting failures in an analyzer for conducting clinical assays. Potential errors that can result in assay failures in an analyzer are identified, as are their potential sources. The probability that an error source so identified will result in a clinically significant error is also determined. Available potential detection measures corresponding to the source of potential errors are identified with a combination of such measures selected and implemented based on their probability of detecting such errors within an acceptable limit with a concomitant low probability of the false detection of an assay failure. Each of the measures selected are functionally independent of others chosen to address the source of the error and are not subject to the same inherent means of failed detection. Applications of the method in a clinical analyzer are also presented.

Title: Slave clock generation system and method for synchronous telecommunications networks
Inventor: LAMB JONATHAN
IPC: G06F1/10
Filed: 2000-04-17
Abstract: A slave clock generation system and method suitable for use with synchronous telecommunications networks generates one or more slave clocks (16) from a selected reference clock (Ts) using a direct digital synthesis technique. A  multiplexer (20) selects a reference clock from a number of available sources (12), each of which can be at its own spot frequency, based on a predetermined selection order. Toggle detectors (42) monitor each of the available clock sources, and block the selection of any that are not within a specified frequency range. A local oscillator (24) establishes short-term and long-term measurement periods; the cycles of the selected reference clock are counted over consecutive short-term measurement periods to determine the relative frequency of the selected clock with respect to the frequency of the local oscillator. The cycle counts are fed to a phase-to-clock converter (80), which produces a slave clock output having a frequency that varies with the relative frequency measured for the selected clock. Rounding errors are countered by monitoring both the generated slave clock and the selected reference clock over a long-term measurement period, with the difference (B-C) between these two cycle counts used in a feedback path to correct the output frequency. The invention's mostly-digital implementation improves its noise-rejection and suppression characteristics, and enables the system to be integrated on a common substrate.

Title: Method for purifying hemoglobin
Inventor: HOUTCHENS ROBERT A
IPC: A61J1/05
Filed: 1999-06-21
Abstract: A method for producing a purified hemoglobin product includes loading a hemoglobin solution onto an anion exchange chromatography column. At least one tris(hydroxymethyl) aminomethane acetate buffer solution is injected into the column. The buffer solution has a pH  lower than that of the column, whereby a purified hemoglobin product elutes from the column. In one embodiment, the hemoglobin solution initially can be equilibrated at a pH of greater than about 8.7. In another embodiment, contaminants can be removed by equilibrating the column with at least about eleven column void volumes of buffer solution at an intermediate pH of between about 8.2 and about 8.6, to thereby form a stepped pH gradient. In still another embodiment, all buffer solutions employed are tris(hydroxymethyl) aminomethane acetate.

Title: Stretch release adhesive article with secondary release member
Inventor: HAMERSKI MICHAEL D
IPC: C09J7/40
Filed: 1999-02-22
Abstract: A stretch releasing adhesive article for removably adhesively bonding an object to a surface includes a stretch release adhesive strip and a secondary release member. The stretch release adhesive strip includes a first adhesive end portion having oppositely facing major surfaces arranged to adhesively bond with the object and the surface and includes a non-adhesive tab portion.  The secondary release member includes oppositely facing adhesive major surfaces having temporary or repositionable adhesive which allows the adhesive article to be repositioned on the surface and object prior to adhesively bonding the stretch release adhesive strip to the surface and object. The adhesive strength of the secondary release member is sufficient to maintain the secondary release member in adhesive contact with the object and surface when the stretch release adhesive strip is stretched during the removal process. After the stretch release adhesive strip is removed from the object and surface, the secondary release member can be removed from the surface by gently peeling or twisting the secondary release member from the surface.

Title: Shift control system for belt-type continuously variable transmission
Inventor: KOYAMA HIDEO
IPC: F16H61/662
Filed: 2001-07-13
Abstract: A shift control system comprises belt-speed calculation means, contact-circle enlarging pulley determination means, diameter-change calculation means, slip prevention thrust calculation means, speed ratio maintaining thrust calculation means and additional thrust calculation means. The diameter- change calculation means calculates the difference between the diameters of the contact circles at present and after a shift to a target speed change ratio, and the slip prevention thrust calculation means calculates a slip prevention thrust necessary for transmitting the power through a V belt without slip between the  V belt and the drive and driven pulleys. The speed ratio maintaining thrust calculation means calculates a speed ratio maintaining thrust that is an addition to the slip prevention thrust for maintaining the current speed change ratio in constant condition and for transmitting the power without any slip of the belt, and the additional thrust calculation means calculates a shifting additional thrust that is added for the contact-circle enlarging pulley to achieve a shift to the target speed change ratio.  The shifting additional thrust is inversely proportional to the running speed of the V belt, which is determined by the belt-speed calculation means, but is proportional to the difference between the diameters of the contact circles.

Title: Method for amplification of molecular bio-assay signals
Inventor: YE FENGCHUN
IPC: C12Q1/68
Filed: 2001-11-23
Abstract: Disclosed are reagents and a method for effective in vitro amplification of bio-assay signals. The method makes use of a pair of "end-to-end" complementary oligonucleotide primers to continuously form a double-stranded and highly repetitive hybrid molecule. Since this hybrid molecule is covalently linked and added to the probing molecule in the bioassays, and is also compatibly labeled, it can amplify the detection signals hundreds of times within a short period. The method can have very broad applications in bioassays using nucleic acid hybridization, immunochemical detection, and other specific interactions between two molecules or between molecules and cells.
