Patent CA-2427228-A1 (CA)
Inventor: FINLAY IAN R
IPC: G06F9/44
Filed: 2003-04-30
Abstract: In an information retrieval system, a query optimization method for transforming maximum or minimum function aggregation predicates on a non-indexed column into a singl e sort function. The method first evaluates the query to identify a table and a predicate equating a column of the table to a sub-query that applies a maximum or minimum aggregation function to the column to return an aggregate value for the column. The aggregate value is used for selecting rows from the table to produce a query result. A determination is then made as to whether an index has not been created using the column of the table. And, in response to these steps of evaluating and determining, the method reforms the query as a sort function on the column. The sort function scans the table once to provide the query result.

Abstract: An interactive doll (1) containing a game unit (3), integral antennas (5a-5c), and a plurality of non-powered playing objects (8). Each playing object (8) contains an RFID (Radio Frequency Identification) tag IC that contains data of different ID information for each playing object (8). When the doll (1) and a play object (8) are position so as to allow RF communication between their antenna, the game unit (3) of the doll (1) sends power to energized the tag IC  of the play object (8). This causes the RFID tag IC to transmit the ID  information data back to the game unit (3) of the doll (1). The doll (1) recognizes the transmitted data and makes a presentation to the user caused by the transmitted data.

Title: Latch apparatus and method
Inventor: EDGAR JAMES R
IPC: E05B65/32
Filed: 2002-01-09
Abstract: In some embodiments of the present invention, a lever is actuatable to unlatch a pawl when the lever is in an unlocked position. When the lever is in a locked position, lever actuation cannot unlatch the pawl. An over-center device coupled to the lever can be used to position the lever in its locked and unlocked positions. In these and other embodiments, the lever is moved away from the pawl when the lever is in a locked position and is moved closer to the pawl when the lever is in an unlocked position. In some embodiments, the lever is pivotable about a pivot point that remains in the same location with respect to the lever in the unlocked and locked positions thereof.  Although not required, the pawl is preferably movable by the lever to its unlatched state after the partially or fully-actuated lever has been moved to its unlocked state.

Abstract: Dispositif et procédé pour la distribution répétée, précise, de faibles volumes de liquide par un orifice de distribution d'un dispositif de distribution de liquide sans contact. Un passage de communication allongé du dispositif de distribution est défini par des parois intérieures présentant une extrémité en communication fluidique avec le réservoir de fluide système, et une extrémité opposée se terminant à l'orifice de distribution. Un fluide système est mis en place dans le passage de communication s'étendant de manière sensiblement continue, du réservoir de fluide système vers l'orifice de distribution. Un volume relativement faible de fluide gazeux est aspiré par l'orifice de distribution dans le passage de communication, de sorte que le fluide gazeux s'étend de manière sensiblement continue dans la dimension transversale du passage. Un liquide de distribution est ensuite aspiré par l'orifice de distribution et dans le passage de communication de sorte que le volume relativement faible de fluide gazeux forme un espace d'air unitaire minuscule, complètement enfermé entre les parois intérieures du passage de communication, et une interface liquide entre le fluide système et le liquide de distribution contenu dans le passage. Cet espace d'air minuscule permet d'empêcher toute dispersion et dilution à l'interface liquide. Pour mettre en oeuvre la distribution, on applique une impulsion rapide de pression présentant une largeur d'impulsion prédéterminée sur le fluide système en amont de l'espace d'air minuscule, l'impulsion de pression traversant cet espace en direction du liquide de distribution sans comprimer sensiblement le fluide de l'espace d'air. Ce système permet de mettre en oeuvre une distribution sensiblement précise et sans contact de volumes relativement faibles de liquide de distribution par l'orifice de distribution.
