IPC: C12Q1/14
Filed: 1999-05-11
Abstract: The invention relates to a dehydrated culture medium for detecting Streptococcus agalactiae by their pigment, wherein only water is adde d and the medium is then shaken prior to utilization. Once rehydrated, a semisolid gel is produced which enables growth of S. agalactiae insid e the medium as pigmented colonies thereby facilitating easy detection. The ne w instant reconstruction medium consists of a dehydrated culture medium and a gel-forming agent. When the user adds ambient temperature water and shakes t he medium, a gel is immediately formed and the medium is then ready for utilization. Streptococcus agalactiae grows in the medium as pigmente d colonies thereby enabling easy detection thereof. Once rehydrated, the mediu m has sufficient consistency for the bacterial growth not to form sediments an d solidifies rapidly enough so that air bubbles are trapped when the medium is  shaken. Said air bubbles remain inside the medium during the incubation peri od and create interphases activating the production of S. agalactiae pigment producing heavily pigmented colonies.

Filed: 1999-08-10
Abstract: The capsular polysaccharide of Escherichia coli K92 contains alternating (-8-NeuAc.alpha.2-) and (-9-NeuAc.alpha.2-) linkages. The enzyme catalyzing this polymerizing reaction has been cloned from the genomic DNA of E. coli K92. The 1.2 kb PCR1 fragment was subcloned in pRSET vector and the protein was expressed in the BL21(DE3) strain of E. coli with a hexameric histidine at its N-terminal end. The enzyme was isolated in the supernatant after lysis of the cells and fractionated by ultracentrifugation. Western blotting using anti-histidine antibody showed the presence of a band that migrated at about 47.5 kD on both reducing and non-reducing SDS-PAGE, indicating a monomeric enzyme.  Among the carbohydrate acceptors tested, N-acetylneuraminic acid and the gangliosides GD3 and GQ1b were preferred substrates. The cell-free enzyme reaction products obtained were characterized by NMR and mass spectrometry, which indicated the presence of both .alpha.2,9- and .alpha.2,8-linked polysialyl structure. The K92 neuS gene was used to transform the K1 strain of E. coli, the capsule of which contains only (-8-NeuAc.alpha.2-) linkages.  Analysis of the polysaccharides isolated from these transformed cells is consistent with the presence of both (-8-NeuAc.alpha.2-) and (-9-NeuAc.alpha.2-) linkages. It is disclosed that the neuS gene product of E. coli K92 catalyzes the synthesis of polysialic acid with .alpha.2,9- and .alpha.2,8-linkages in vitro and in vivo.

Filed: 2001-03-07
Abstract: Apparatus is provided herein for receiving crank case emissions from an internal combustion engine and chemically altering the vapor portions of the emissions back into usable volatile gasses to be used as fuel. The apparatus includes housing, an inlet which is connected to a crank case vent to take in crank case emissions, and outlet which is connected to intake manifold which is connected to combustion chamber of an internal combustion engine. Catalyst materials are positioned in housing between inlet and outlet in such a way as to create a catalyst reaction. These crankcase gases, essentially made up of long chain hydrocarbons, are chemically altered by passing through this catalyst and emerged as a completely changed hydrocarbon, This new hydrocarbon compound once re-introduced into the combustion chamber of engine has the ability to stabilize combustion of the fuel allowing a more complete stable explosion, enhancing engine performance and creating cleaner emissions.

Abstract: The present invention relates to a method for downlink power control in the base station of a code division multiple access (CDMA) communication system.  The total assigned downlink power from the base station is adjusted to a maximum downlink power level by means of individually adjusting the assigned bit rates of an appropriately selected subset of downlink channels to those users having a data communication connection. Said subset is retrieved by applying suitable selection criterions for the downlink channel, e.g., the momentarily assigned bit rate, the reported pathloss, or the user subscription type.

Title: Verification de conformite pour la detection d'anomalies
Inventor: GOLDSCHMIDT PETER SOLLY
IPC: G06N5/04
Filed: 2000-04-07
Abstract: L'invention concerne un procédé et un système servant à aider le vérificateur de conformité à réaliser une vérification de conformité pour la détection d'anomalies (CMAD). Ce procédé et ce système font appel à un système de vérification primaire qui compare un certain nombre de conditions d'acceptations prédéterminées avec des données ou des événements actuels. Si un quelconque écart est détecté (une anomalie) par le système de vérification primaire, un rapport d'anomalies ou une alerte est produit(e), lequel ou laquelle identifie l'écart. Dans un environnement simple, cette identification d'écart remplit les conditions de preuves et détermine ainsi une instance de non-conformité. Toutefois, dans un environnement plus complexe, elle peut simplement servir d'indicateur d'un événement supposé non conforme (SNCE). Dans ce cas, le vérificateur de conformité utilise les résultats de la vérification initiale et des informations importantes relatives à l'événement et nécessitant des compétences appréciatives pour obtenir d'autres preuves de non conformité. Les vérificateurs de conformité développent des propositions et des convictions, sur la base de leurs hypothèses. Pour chaque noeud de proposition dans le système, le système de maintien vérifonctionnel fondé sur des hypothèses tient une liste d'ensembles minimum d'hypothèses (signaux booléens) appropriée au type SNCE. Au niveau de la macro-analyse, le concept fait appel à un trinôme conviction-incrédulité-inconnue. Cependant, l'analyse est affinée par l'application d'une mesure d'importance à des éléments individuels de preuves empiriques.

Abstract: A differential SAW filter having a cascaded structure includes an input SAW  stage and an output SAW stage. The two SAW stages are configured so that the distance of travel of the surface acoustic waves from a single unbalanced input of the input stage to the dual balanced outputs of the output stage is electrically equidistant, thus resulting in a balanced differential output. The input stage includes a single unbalanced input coupled to a pair of outer IDTs, which both launch a surface acoustic wave to a single input stage inner IDT. The input stage inner IDT connects to the input IDT of the output SAW stage, which launches a surface acoustic wave to a pair of identical but inverted output IDTs that form the differential, balanced output signals.
