Patent CA-2370122-C (CA)
Title: Rapid and efficient capture of dna from sample without using cell lysing reagent
Inventor: BELLY ROBERT T
IPC: C12Q1/6886
Filed: 2000-05-01
Granted: 2011-04-26
Abstract: Nucleic acids can be made available for amplification or other treatment after admixture of a sample with specific weakly basic polymers to form a precipitate with the nucleic acids at acidic pH. After removing non-precipitated materials, the pH is then made basic, thereby releasing the nucleic acids from the polymer. This method for preparing specimen samples is simple and quite rapid, and the released nucleic acids can be further treated in hybridization assays or amplification procedures. No surfactant or other cell lysing reagents are employed. The weakly basic polymers are water-soluble and cationic at acidic pH, but neutral in charge at basic pH.

Title: Sample extraction system for boreholes
Inventor: BELSHAW DOUGLAS JAMES
IPC: E21B33/10
Filed: 2002-03-20
Granted: 2009-11-24
Abstract: The use of extruded plastic continuous-multi-channel (CMC) tubing for conveying water samples from different depths up out of boreholes is enhanced by the compressed- grommet sealing system as described. The rubber grommet is placed inside one of the many conduits of the tubing, and squeezed lengthwise, whereby the grommet expands laterally and seals and plugs the conduit. When forming a port in the conduit, an aperture is cut in the wall of the conduit, and plug-assemblies having the grommets are placed above and below the port. Ledges on the plug--assemblies engage the ends of the aperture, and operate in ocnjunction with spacer bars in the aperture to prevent the plug-assemblies being moved along the conduit by pressure in the conduit. Some of the conduits in the CMC tubing are left unplugged, for admitting probes, sensors, etc.

Abstract: The present invention provides the use of nucleic acid sequences and/or amino acid sequences in the preparation of a vaccine for the protection of fish against infectious salmon anaemia virus.  Specifically, such vaccines contain at least one nucleic acid sequence which is derived from ISAV or synthetically prepared analogues thereof, or substantially homologous sequences. These nucleic acid sequences are transcripted and translated into peptide sequences which are incorporated into a vaccination strategy to induce an immune response to the surface antigens of ISAV and therefore ISAV  itself. Therefore both the use of a vaccine against ISAV, and the incorporation of peptide sequences is herein described.

Filed: 2001-01-23
Granted: 2011-02-15
Abstract: The present invention relates to a method and a system for calibration of a sound field to be used during fine-tuning of an auditory prosthesis. An auditory prosthesis is provided for compensation of hearing loss and for sound pressure determination. During calibration of the sound field to be used during fine tuning of the auditory prosthesis, the auditory prosthesis is positioned at an observation point in the sound field, and the sound pressure at the auditory prosthesis is adjusted based on determinations of sound pressures performed with the auditory prosthesis.  Thus, the need for dedicated calibrated sound pressure determining equipment is eliminated.

Abstract: des données d'image numérisées sont entrées dans un processeur dans lequel un élément de détection identifie les régions (objets) qui présentent un intérêt particulier dans l'image et, par segmentation, isole ces objets de l'arrière-plan. Un élément d'extraction de caractéristiques formule des valeurs numériques adaptées au travail de classification à partir des objets segmentés. Les résultats issus des opérations d'analyse précédentes sont entrés dans un classificateur de machine d'apprentissage programmée qui génère une sortie pouvant se présenter sous la forme d'un index qui permet de distinguer entre deux diagnostics possibles, ou tout autre forme de sortie dans le format requis. Selon un mode de réalisation, les données d'image numérisées sont entrées dans une pluralité de sous-systèmes comportant chacun une ou plusieurs machines à vecteur de soutien. Le prétraitement fait intervenir des transformations connues qui facilitent l'extraction des données utiles. Chaque sous-système analyse les données qui se rapportent à une caractéristique différente détectée dans l'image. Lorsque chacun des sous-systèmes a terminé son analyse et son classement, le résultat de l'ensemble des sous-systèmes est entré dans un analyseur pour machine de vecteur de soutien global qui combine les données pour formuler un diagnostic, prendre une décision ou lancer une action qui utilise les connaissances tirées de l'image.
