Title: Encapsulated active materials
Inventor: BITLER STEVEN P
IPC: B01J35/02
Filed: 1999-04-27
Abstract: The invention is an encapsulated active agent comprising an active agent encapsulated in a crystallizable or thermoplastic polymer wherein the particle size of the encapsulated active agent is 3,000 microns or less wherein the active agent is not significantly extractable from the particles under ambient conditions. In another embodiment the invention is a process for preparing an encapsulated agent which comprises: a) contacting an active agent with a crystallizable or thermoplastic polymer wherein the polymer is molten and the active agent is not volatile under the contacting conditions; b) forming particles of 3000 microns or less; and c) exposing the particles to conditions such that the portion of the particle at and near the surface undergoes rapid solidification. The encapsulated active agents of the invention do not require washing in order for them to be stable in curable compositions.  These encapsulated active agents can be designed to release the active agent at a desired temperature. The encapsulated agents of the invention demonstrate excellent stability at ambient temperatures and exhibit relatively rapid reactivity upon release of the active agent.  Furthermore, the presence of the encapsulating agent does not result in deterioration of adhesive or elastomer properties of a cured composition after preparation.

Patent CA-2345780-A1 (CA)
Inventor: WATSON KRISTIN L
IPC: A61H23/04
Filed: 1999-10-04
Abstract: A method for augmenting blood circulation in the limb of a patient is provided by customizing the compression cycle based upon patient venous characteristics. The method measures the venous refill time of the patient for use with an intermittent pneumatic compression device. A limb such as a leg is wrapped with a compression sleeve having at least one pressurizable chamber. The chamber is pressurized for a predetermined period of time to compress the limb and cause blood to flow out of the limb. The chamber is depressurized until the pressure in the chamber reaches a lower value, and the chamber is closed. The pressure in the chamber is sensed and the venous refill time, the time for the limb to refill with blood, is determined by sensing when the pressure reaches or will reach a plateau. The venous refill time is used as the basis for the time between subsequent compression pulses of the compression device.

Abstract: Un ballast DHI comprend un circuit de commande qui minimise l'instabilité d'arc associée à la résonance acoustique d'une lampe excitée par le ballast. Dans un mode de réalisation, le ballast comprend un circuit inverseur possédant des premier et deuxième éléments de commutation couplés selon une configuration de demi-pont. Un premier circuit de commande commande l'état de conduction du premier élément de commutation et un deuxième circuit de commande commande l'état de conduction du deuxième élément de commutation. Le deuxième circuit de commande comprend un circuit limiteur qui limite les niveaux d'énergie pré et post-allumage de la lampe. Ledit circuit se caractérise, entre autres, en ce que l'amplitude du courant de la lampe est limité, de sorte que cette dernière puisse être excitée lorsqu'elle est en résonance acoustique. Dans un autre mode de réalisation, le circuit inverseur comporte un élément inductif résonant et un élément capacitif résonant couplé en parallèle à la lampe. L'élément capacitif résonant présente une caractéristique d'impédance dépendant de la température, de sorte que la fréquence de résonance du circuit inverseur soit modifiée à mesure que le circuit chauffe avant l'allumage de la lampe. A mesure que l'élément capacitif chauffe, la fréquence de résonance de l'inverseur augmente, ce qui augmente la tension appliquée sur la lampe jusqu'à ce qu'un arc soit amorcé. Le circuit se caractérise également en ce que la tension moyenne appliquée sur la lampe avant et après l'allumage est limitée ainsi que la tension appliquée sur la lampe, cycle par cycle.

Title: Multi-player gaming platform allowing independent play on common visual display
Inventor: CANTERBURY STEPHEN A
IPC: A63F3/00
Filed: 2001-08-31
Abstract: A multi-player gaming platform includes a large visual display and a plurality of player terminals coupled to the visual display. The visual display indicates a game of chance including a single play field and a plurality of movable game pieces. The game pieces are associated with the respective player terminals. In response to a wager placed at one of the player terminals, the game piece associated with that terminal moves along or near the play field and generates a game outcome. The game outcome may be defined by the game piece itself or where the game piece lands on the play field. The game awards a payoff if the game outcome meets winning criteria. The wager placed at the one of the player terminals is independent of any other wagers placed at the other player terminals and is independent of when the other wagers are placed. Similarly, the game piece associated with the one of the player terminals operates independent of the game pieces associated with the other player terminals. There is no actual player-to-player interaction--the players merely make use of the same play field. Therefore, the gaming platform allows players to join the game of chance at any time and to place wagers, make any necessary selections, and play the game at their own pace.

Title: Placement guide for ablation devices
Inventor: MIKUS PAUL W
IPC: A61M25/08
Filed: 2000-03-08
Abstract: A placement guide for positioning ablation devices within a human body is disclosed. The placement guide comprises an outer catheter (10), and an inne r tubular member (15) disposed within a lumen of the outer catheter. When a st op (30) on the inner tubular member engages a seat (35) on the outer catheter, a distal projection (40) of the inner tubular member extends from the distal e nd of the outer catheter. While monitoring the position of the inner tubular member through an endoscope inserted in its lumen, a clinician positions the  distal projection within a human body for optimal ablation. After securing t he outer catheter in position, the inner tubular member is withdrawn, and replaced with an ablation device (55) which is inserted distally within the outer catheter lumen until a stop on the ablation device engages the seat on  the outer catheter wherein a distal projection (60) of the ablation device extends from the distal end of the outer catheter. Because the distal projection of the inner tubular member has a length substantially identical to that of the inner tubular member, the ablation device may be positioned for optimal ablation.

Abstract: Disclosed is a method of manufacturing a mechanically and chemically embossed surface covering having selectively textured surfaces. The method includes forming a web coated with a wear layer. The coated web is heated to a temperature at which the wear layer is cured; the foam layer expands, and the pattern is chemically embossed to form a surface covering having foamed regions and nonfoamed regions. The temperature gradient of the surface covering is adjusted such that there is a temperature gradient difference between the foamed and nonfoamed regions. A surface texture is then mechanically embossed into the wear layer and selectively set onto the wear layer substantially overlying the non-foamed regions.

Abstract: The invention includes a heating apparatus for biological samples. The heating apparatus of the present invention includes a cover, a sample block having a plurality of openings in a top portion thereof for receiving a sample well tray having a plurality of sample wells, and an urging mechanism. The urging mechanism is positionable between the sample block and the sample well tray to urge the sample well tray away from the sample block when the cover is moved from a closed position toward an open position. The cover imparts a downward force on the top of the sample well tray to press the sample wells into the openings of the sample block when the heated cover is moved toward a closed position.   The urging mechanism imparts an upward force on the sample well tray.      The downward force imparted by the heated cover is sufficient to retain the sample well tray against the sample block when the cover is in the closed position.
