Patent CA-2341182-C (CA)
Inventor: GIANCHANDANI YOGESH B
IPC: G01L9/00
Filed: 1999-08-17
Granted: 2005-01-04
Abstract: A micromachined pressure sensor is formed with a minimum number of masking and processing steps. The structure measures changes in pressure by deflection of structures having capacitive plates external to a sealed cavity so that electrical leads can be readily connected to the plates formed on the structures. The pressure sensor includes a substrate, a base secured to the substrate and a diaphragm secured to the base to define a sealed cavity. A  skirt may extend outwardly from the base above the substrate to form one of the plates of the capacitor with another plate formed on the base. Changes in ambient pressure deflect the skirt toward or away from the electrode on the substrate, changing the effective capacitance between the electrodes.  Electrical connections may be made to the electrode on the skirt and the electrode on the substrate utilizing electrical connectors which are external to the base and thus external to the sealed cavity.

Abstract: L'invention concerne un procédé permettant de fabriquer des paillettes métalliques à rapport de forme élevé d'une manière économique et à un rendement élevé. Ledit procédé consiste à appliquer un sandwich multicouche de métal déposé en phase vapeur et des revêtements antiadhésifs en couches alternées sur un tambour trempé à froid rotatif ou un support approprié dans une chambre d'évaporation sous vide. Les couches métallisées alternées sont appliquées par évaporation sous vide et les couches antiadhésives intermédiaires sont, de préférence, des matériaux solubles dans l'eau ou des solvants appliqués par des sources de revêtement ou de dépôt appropriées contenues dans la chambre d'évaporation. Les matériaux de revêtement antiadhésif peuvent être un polymère thermoplastique soluble dans un solvant, un sel inorganique soluble dans l'eau ou une substance de type cire soluble que l'on peut dissoudre à un point d'ébullition élevé. Le sandwich multicouche, formé dans la chambre sous vide, est retiré du tambour ou du support et traité par un solvant approprié ou par de l'eau afin de dissoudre le revêtement antiadhésif sur le métal selon un procédé de décapage qui laisse les paillettes métalliques essentiellement exemptes de revêtement antiadhésif. Le solvant ou l'eau et le matériau antiadhésif dissous sont ensuite éliminés par centrifugation afin de produire un gâteau de paillettes concentrées que l'on peut broyer à l'air et laisser tomber dans un milieu de suspension préféré, puis dimensionner et homogénéiser pour usage final dans des encres, peintures ou revêtements.

Filed: 2001-06-07
Granted: 2013-07-30
Abstract: A method and apparatus for delivering targeted assets to subscribers using communication media, wherein each subscriber has a set top box, the method comprising the steps of generating a profile of each subscriber at the set top box associated with the respective subscriber, broadcasting an asset to all subscribers along with target information; and delivering the asset only to subscribers whose profiles match the target information. The delivery of the asset, and accumulated information from delivery of the asset to other subscribers, is reported to a user using an asset delivery notification, without identifying the subscriber to the user. A privacy manager is used to strip identification information from the asset delivery notification. The profile, which may include real time information, for example on whether the subscriber set is on and what it is tuned to, is generated by monitoring the viewing habits of the subscriber and storing the information at a set top box.

Abstract: One or more electric and/or data transmitting cables are confined in an elongated strip-shaped body containing a hardenable resin or the like, and the body is placed against a portion of the internal surface of an underground sewage, water or other pipe. An expandable tubular liner is thereupon introduced into the pipe and is expanded to press the body against the pipe. The body is caused to set, by conveying a hot fluid through the liner and/or by electrically heating the cable or cables, and to adhere to the internal surface of the pipe. The liner can remain in the pipe and can be bonded to the strip-shaped body and/or to the remaining portion of the internal surface of the pipe. Alternatively, the liner is caused to collapse and is withdrawn from the pipe once the strip-shaped body is bonded to the internal surface of the pipe.

Abstract: Methods for making a loaded catheter assembly for delivering a sel-expanding stent where the self-expanding stent is carried in a compressed state and the compressed stent has an inside diameter smaller than the outside diameter of the catheter distal tip. The methods can utilize catheter sub-assemblies lacking already attached tips or having partially formed distal tips. A stent can be proximally and co-axially slid over the distal end of the catheter shaft and constrained by a retractable sheath disposed co-axially about the compressed stent. The catheter distal tip can be added or more fully formed after the loading of the stent. Some catheters include a preformed distal conical tip held in position by a heat- shrink film. Other catheters have an elastomeric distal tip waist for slipping over and engaging an outward projection on the catheter shaft distal region. Some catheters are adapted to engage catheter shaft distal threaded regions.
