Title: Extensible indexing
Inventor: NORI ANIL
IPC: G06F17/30
Filed: 1997-07-01
Granted: 2004-01-20
Abstract: A method and apparatus for processing a query in a database system using index types that are not built into the database system are disclosed. Routines for managing an index structure that is not supported by a database system are generated. Data that identify the routines are submitted to the database system, thereby "registering" the index types with the database system. In response to statements issued to the database system by a client, the database system call the routines, causing the routines to create an index structure using data from a data container in the database, and to generate data that indicates which data in the data container satisfies a query issued by the client. The routines of the registered index type extend the indexing capabilities of the database systems and one or more such index types can be registered with the database system. The index structure managed by the routines may be maintained within segments of the database, and the segments may be accessed as index-only tables. Storing a row of data in a database using index-only tables involves storing in a leaf node an index entry that includes a key value along with all other values in the row of data. If the row of data exceeds a predetermined size, then a portion of the row data is stored in an overflow area. Retrieving a row of data from an index-only table for a user-supplied key involves identifying a leaf node for the key, and reading a row of data from the index entry and any remaining portion from the overflow area when the row exceeds the predetermined size.

Abstract: A complex filter minimizing mismatch error by averaging the mismatch error by integrating the real and imaginary input signals using the same integrator. A  further advantage is that, as compared to known devices, the complex filter uses fewer number of components thereby reducing the consumed power. The complex filter may be used in a complex bandpass sigma-delta modulator, thereby increasing the performance of the sigma-delta modulator. The complex filter used in a sigma-delta modulator analog to digital converter increases performance of the analog to digital conversion since the mismatch noise is minimized. The complex bandpass sigma-delta modulator analog to digital converter include any number of complex filter stages.

Abstract: The present invention relates to a cooled blade of a gas turbine, and in particular an object of the present invention is to reduce thermal stress around air-transpiration holes (4) provided for shower-head cooling of a leading edge portion of a blade.      A number of air-transpiration holes (4) are provided at a leading edge portion (2) of a cooled blade (1). Cooling air flowing through a cooling air passage (15) formed inside of the blade blowout to the blade surface of the leading edge portion (2) of the cooled blade (1) by way of the air-transpiration holes (4), to thereby shower-head cool the surface of the leading edge portion (2). In the conventional blade, the air-transpiration holes (14) are formed obliquely to the leading edge portion (2), whereby acute-angled portions (30) are formed at inlet/outlet ports of the air-transpiration holes (14) in the leading edge portion (2), and thus cracks due to thermal stress develop around the air-transpiration holes (14). In contrast, according to the present invention, the air-transpiration holes (4) are formed so as to extend substantially orthogonal to the leading edge surface of the cooled blade (1) such that the acute-angled portions are eliminated, whereby thermal stress can be reduced and thus the cracks can be prevented.

Title: Conductive polyacetal composition
Inventor: THIELEN ALAIN

Filed: 1997-10-23
Granted: 2004-03-16
Abstract: An electrically conductive polyacetal composition having improved toughness and flexibility, as well as good fluidity and processability. The composition includes an oxymethylene polymer, an elastomeric polyurethane, and an electrically conductive carbon black having a lower structure level (DBP absorption) and larger particle size (lower surface area) than conductive carbon blacks heretofore used in these compositions. The composition includes between about 65 and about 85 percent, by weight, of the oxymethylene polymer, between about 10 and about 20 percent, by weight, of the electrically conductive carbon black, and between about 10 and about 20 percent, by weight, of the elastomeric polyurethane. The electrically conductive carbon black has a surface area BET (N2) of between about 40 and about 100 m2/g, and a pore volume, DBP absorption, of between about 150 and about 350 ml/ 100g. The electrically conductive carbon black used in the present compositions is more easily dispersed in the composition polymers and lessens any increase in melt viscosity during compounding.

Abstract: Conventional syringe pumps have a plunger head retainer and some means for detecting occlusion or other restriction to movement of the plunger. In the present invention, the plunger head retainer has two retainer arms mounted on shafts extending parallel to the syringe axis. Each shaft carries a gear, which is engaged by common gear wheel mounted on a threaded shaft. Initially, the shaft is rotated to displaces the gear and hence the retainer arms axially forwardly, and thereafter swing the retainer arms outwardly to an open position. After the syringe has been loaded in the pump, the plunger head retainer is driven forwards until a pad coupled with a force sensor detects contact with the head. This causes the retainer arms to be swung in across the forward side of the plunger head and to be pulled rearwardly against the plunger head. The pump then reduces the force applied by the retainer arms to ensure that the force sensor can respond to force on the plunger during expulsion of liquid from the syringe.

Abstract: Cette méthode de reconnaissance et de détection des couleurs vise à permettre la reconnaissance et le tri d'objets. On reçoit des pixels d'une image couleur d'un objet à reconnaître, on détermine alors la teinte, l'intensité et/ou la saturation de chacun de ces pixels. Ces valeurs de teinte, d'intensité et/ou de saturation de chaque pixel reçu sont assignées à plusieurs teintes, intensités et/ou bandes de saturation prédéterminées, respectivement, afin d'obtenir des valeurs de distribution de teinte, d'intensité et/ou de saturation, respectivement, pour l'image couleur. On compare ces valeurs de distribution relatives à l'image couleur à des valeurs de distribution provenant d'un ou de plusieurs objets de référence afin de déterminer si l'objet est reconnu comme un objet de référence. Cette méthode de reconnaissance d'objet n'est pas influencée par la complexité de l'image ni par le nombre de couleurs de l'objet à reconnaître. Elle repose sur la comparaison d'une signature de teinte de l'objet à reconnaître avec la signature de teinte d'un objet de référence.
