Patent CA-2373144-A1 (CA)
Title: High frequency measuring circuit with inherent noise reduction for resonating chemical sensors
Inventor: DILGER JOHN P
IPC: G01N27/00
Filed: 2000-04-26
Abstract: The concentration of an analyte in a fluid is measured by a quartz crystal microbalance sensor device (10) in the fluid containing a concentration of the analyte. The sensor device exhibits a resonant frequency representative of the concentration of the analyte in the fluid.  A quartz crystal microbalance reference device (16) has a resonant frequency lower, by a predetermined amount, than the initial resonant frequency of the sensor device before the sensor device is exposed to the analyte. A signal is derived based on the difference of the resonant frequencies of the sensor and the reference device, and a first counter (20) counts a predetermined number of cycles of the difference signal frequency to derive a sample time period. A second counter (24) counts cycles of a clock signal frequency during the sample time period to derive a count representative of the difference signal frequency.

Inventor: HOLLINGSWORTH DAVID E
IPC: G06F17/21
Filed: 2000-07-20
Abstract: To process the layout of graphical objects, elastic data structures are established for the graphical objects to define minimum and preferred sizes, stretch properties and compression properties.  One application of elastics is with respect to text blocks where preferred width and compressibility of each text block is a function of the amount of text in the text block. Composite graph-ical objects include elastic properties computed from their components through add and max operations which are dependent on relative elasticities of the components. The positions of origins within graphical objects are defined by pairs of elastics in each of two dimensions. The default width or height preference of a graphic object can be overridden. Overriding elastics is an effective mechanism for altering the display characteristics of graphical objects while preserving certain display relationships. The elastics and dimensions of graphical objects are processed in a three pass layout negotiation. In the first pass, preferred sizes and elasticities of the graphical objects are computed along a first dimension. In a second pass, size values of the graphical objects along the first dimension are computed from the preferred sizes and elasticities, and preferred sizes and elasticities of the graphical objects along a second dimension are computed based on the size values of the graphical objects along the first dimension. In a final pass, size values of the graphical objects along the second dimension are computed from the preferred sizes and elasticities.

Abstract: A microcapsule composition comprising a core material in a matrix of polymorphic shell material, releases said core material in an aqueous environment in accordance with zero order linear release profile. A preferred composition comprises a core material having a degree of water solubility entrapped in a beta crystalline matrix of water insoluble shell material which matrix may, optionally, be surrounded by a contiguous core material-free layer of water insoluble shell material. Also disclosed is a process for the preparation of microcapsules comprising subjecting a flowable mixture of core material and a first amount of water insoluble shell material to a pressure force to form a pressure-treated mixture, and passing said pressure-treated mixture through a spray nozzle into a chilling zone to form a solidified composition. A special embodiment of the method providing for the long term moisture stability of the resulting microcapsules subjects the microcapsules prepared in the first step to a second coating with a second amount of water insoluble shell material.

Abstract: L'invention concerne un dispositif d'administration de médicament, par exemple une forme posologique orale avec un noyau toxique ou actif enrobé d'une zone non toxique. Cette zone peut comporter plusieurs couches, revêtements, enveloppes ainsi que des combinaisons de ceux-ci, ce qui permet de protéger et d'isoler le noyau actif ou toxique. Le médicament contenu dans ledit noyau est incorporé dans la forme posologique par le biais, par exemple, d'impression tridimensionnelle, comme solution, solubilisation ou suspension de particules solides dans un liquide, plutôt que par le traitement et la compression plus classiques de poudre sèche. On minimise la probabilité de créer des particules aériennes du médicament toxique lors de la fabrication. Ainsi, on contrôle et on minimise l'exposition du personnel de fabrication à la matière dangereuse. La distribution humide du médicament toxique ou actif offre en outre au patient une plus grande biodisponibilité du médicament.

Title: Method and system for measuring one-way delay variation
Inventor: BROWN MICHAEL
IPC: H04L12/26
Filed: 2001-05-15
Abstract: A method and a system for measuring one-way delay variation in a network transmits probe packets with a transmission time indication and a sequence number. The network receives a first probe packet and a second probe packet and notes their arrival times. If the two probe packets are sequential, the one-way delay variation is calculated between the two probe packets. The delay variation is equal to the difference in arrival time between the first and second probe packets minus the difference in the transmission time between the first and second probe packets.

Title: Methods for high-temperature hydrolysis of galactose-containing oligosaccharides in complex mixtures
Inventor: KELLY ROBERT M
IPC: A23K1/165
Filed: 2001-07-20
Abstract: .alpha.-Galactosidases from hyperthermophilic sources are useful in treating  animal feed by hydrolyzing the galactose oligosaccharides present in animal feeds. .alpha.-galactosidases from Thermotoga maritima are useful in hydrolyzing raffinose, stachyose and verbascose, indigestible oligosaccharid es commonly found in animal feed compositions. The ability to use these enzymes  at high temperatures, namely those that would normally be encountered in industrial processes typically associated with animal feed formulation or processing, is advantageous for adding nutritive value to animal feed and flexibility in processing. Hyperthermophilic .alpha.-galactosidases are also  useful as food additives for human food.
