Abstract: Une méthode permet d'estimer les besoins en matière de stockage pour une configuration de groupement de données à plusieurs dimensions. Le stockage requis pour les données groupées à plusieurs dimensions est estimé en modélisant l'espace inutilisé. La quantité d'espace inutilisé peut être modélisée en calculant la cardinalité de la valeur unique de la clé de groupement de la configuration proposée. La cardinalité peut être déterminée à l'aide de techniques d'estimation. Des valeurs spécifiques d'espace inutilisé et d'espace total peuvent être déterminées par rapport à la cardinalité déterminée. La comparaison des estimations de différentes configurations de groupements proposées peut faciliter la sélection parmi les propositions.

Abstract: Selon l'invention, une surface comportant un matériau infecté par les prions peut être nettoyée au moyen d'une solution de nettoyage alcaline, de sorte à éliminer autant de matériau protéinique que possible de cette surface. Cet agent de nettoyage est un agent de nettoyage alcalin qui attaque les prions se trouvant sur la surface, ainsi que les prions retirés de cette surface pendant l'étape de nettoyage. Après drainage de ladite solution de nettoyage, une solution de tensioactifs, de tampons et d'inhibiteurs de corrosion exempts de métaux lourds est acheminée sur la surface, à une température comprise entre 50 et 60 ·C. Les tensioactifs dispersent et séparent le matériau contaminé par les prions. Un oxydant fort, de préférence de l'acide péracétique, est ajouté à la solution pour amener la concentration d'acide péracétique entre 1000 et 2500 ppm. L'acide péracétique ou un autre oxydant fort attaque les prions, en particulier les souches de prions séparées, ce qui désactive les prions. Après rinçage et séchage, la surface peut être enveloppée dans une barrière imperméable aux microbes et soumise à une stérilisation finale, telle qu'une stérilisation en autoclave à la vapeur.

Granted: 2012-07-17
Abstract: The invention relates to a method for coupling proteins to a starch-derived modified polysaccharide. The binding interaction between the modified polysaccharide and the protein is based on a covalent bond which is the result of a coupling reaction between the terminal aldehyde group or a functional group of the modified polysaccharide molecule resulting from the chemical reaction of this aldehyde group and a functional group of the protein which reacts with the aldehyde group or with the resulting functional group of the polysaccharide molecule. The bond directly resulting from the coupling reaction can be optionally modified by a further reaction to the aforementioned covalent bond. The invention further relates to pharmaceutical compositions that comprise conjugates formed in this coupling process and to the use of said conjugates and compositions for the prophylaxis or therapy of the human or animal body.

Title: A method for controlling the quality of industrial processes and system therefor
Inventor: D ANGELO GIUSEPPE
IPC: G06F19/00
Filed: 2005-02-16
Granted: 2012-07-17
Abstract: There is provided a method for monitoring and controlling the quality of an industrial process. One or more reference signals relating to the industrial process are compared to one or more real signals that are indicative of the quality of the industrial process. Transformed signals are obtained from the reference signal and real signal and the energies of the transformed signals are then calculated. The comparison involves comparing the energies of the transformed signals to extract corresponding time frequency distributions for selected frequency values. The energies of the time frequency distributions are calculated and compared with threshold values to identify energy values associated with defects, which latter energy values are then provided to a defects classifier. The classifier identifies and evaluates the quality of the industrial process.

Patent CA-2513472-C (CA)
Inventor: SHELTON FREDERICK E IV
IPC: A61B17/068
Filed: 2005-07-26
Granted: 2015-02-10
Abstract: A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A spring-biased side pawl firing mechanism is enabled by activation of an Electroactive Polymer (EAP) block actuator that overcomes a disengagement spring bias and moves a linked rack into proximity with a side pawl firing mechanism. Thereby, various sensed or commanded inputs may be incorporated to prevent inadvertent firing.

Title: Hand held appliances
Inventor: HAWES CHRISTOPHER MARTIN
IPC: B26B21/40
Filed: 2004-02-19
Granted: 2012-11-06
Abstract: A hand held electrical appliance having a handle and a head part to be brought into contact with the body of the user, such as a toothbrush with a brush head, and especially a safety razor with a head part in the form of a blade unit (2), wherein an electrically operable vibration generating device, for example an electric motor (24) and eccentric weight (26), and a control device (16) for controlling operation of the vibration generating device are provided. The control device is proximity or touch sensitive and includes a sensor element, such as an electrode formed by a blade (4) of the blade unit (2), so that the vibration generating device is actuated in response to a person using the appliance moving the blade unit (or other head part) into close proximity to or into contact with the body area to be treated. Due to the vibration generating device being operated only when the head part is applied or about to be applied to the body, the discomfort of holding a vibrating appliance in the hand, as perceived by a user, is greatly diminished.

Abstract: A method and apparatus for manufacturing a catalytic converter (2) is described where the catalytic converter (2) is comprised of an outer tube member (4) having a monolith substrate (6) internally compressed therein with a wrapped mat material (8) surrounding the monolith substrate (6) and intermediate the outer tube (4). One or more monolith members (4, 6) can be applied within the outer tube (4) and heat shields (12, 20) may also be applied internal to the outer tube (4) and adjacent to the monolith substrate (6). The assembly of the catalytic converter (2) includes measuring the sequence of compression of the mat material (8) to the monolith substrate (6) in order to understand the possible force characteristics that can be applied during the assembly thereof. The mat material (8) is therefore compressed within the outer tube (4) by way of compression jaws (194), by compression rollers (94), spinning, and/or by via a shrinker mechanism (400, 500, 600).  The compression of the mat material (8) can be in single or multiple steps.
