Abstract: Les données d'identification origine (empreintes digitales) sont injectées dans la zone d'image active d'un signal vidéo sans interférer avec la visualisation obtenue au moyen du signal vidéo. Les données sont récupérées ensuite par un lecteur de données ou "Lecteur d'Empreintes Digitales". Le procédé d'injection des données ou de "reproduction d'empreintes digitales" consiste à décaler dynamiquement le palier de suppression vidéo de façon à véhiculer l'information qui peut être restituée en lecture depuis n'importe quelle bande vidéo réalisée à partir de la sortie de l'unité d'injection de données. En l'occurrence, l'empreinte digitale comporte le numéro d'identification de l'unité utilisée et la date du jour. Le décalage dure une zone entière et présente une amplitude d'environ 0,5 unités I.R.E., c'est à dire qu'une zone spécifique présentera des caractéristiques constitutives nominales ou des valeurs de caractéristiques constitutives s'écartant de 0,5 unités I.R.E. des valeurs nominales. Les données se répètent toutes les 128 zones de façon à fournir au lecteur un vaste échantillonnage et à afficher les données d'identification origine.

Title: Procede de montage comprenant la separation des pieces d'une chambre de pompage compressible monobloc
Inventor: STAHLEY ROBERT EDWARD
IPC: B05B11/00
Filed: 1995-09-29
Granted: 2000-04-11
Abstract: L'invention concerne une chambre de pompage (60) compressible qui comprend plusieurs éléments fonctionnels d'un dispositif à pompe (20). Par exemple la chambre de pompage (60) compressible peut être un soufflet (60) qui comprend, comme éléments fonctionnels, une soupape de sortie (80), un élément exerçant une sollicitation et une chambre de tourbillonnement. Ainsi des éléments fonctionnels assurant toutes les fonctions à remplir en aval du dispositif sont incorporées au soufflet (60). Cela peut entraîner une réduction importante des coûts étant donné, par exemple, que l'outillage est réduit et que le nombre des opérations de montage est également réduit. Puisqu'il peut être souhaitable de séparer lesdits éléments fonctionnels (par exemple pour obtenir une pulvérisation plus uniforme), il est décrit un procédé permettant de séparer les divers éléments fonctionnels de la chambre de pompage (60) compressible, à éléments fonctionnels multiples, pendant le montage du dispositif à pompe (20). On décrit également un élément servant à réduire le volume défini par la chambre de pompage comprimée.

Abstract: Protéine CD de membrane externe non dénaturée isolée et purifiée qui est isolable à partir d'une souche Moraxella, en particulier M. catarrhalis ou correspond à ladite souche. Ladite protéine CD est isolée d'une souche bactérienne par séparation par centrifugation d'un lysat cellulaire obtenu par éclatement d'une masse cellulaire de la souche bactérienne pour obtenir un culot et un surnageant à éliminer contenant une importante proportion de protéines bactériennes solubles. Le culot est extrait sélectivement pour éliminer les protéines solubles restantes, les protéines de membrane autres que CD et d'autres contaminants tels que le lipopolysaccharide et des phospholipides. Le culot restant contenant la CD est dispersé et solubilisé, puis séparé par centrifugation pour éliminer les débris cellulaires restants. La protéine CD est utile dans des applications diagnostiques et dans des compositions immunogènes, en particulier pour une administration in vivo à un hôte afin de conférer à cet hôte une protection contre des maladies causées par un germe pathogène bactérien qui produit de la protéine CD ou produit une protéine capable d'induire des anticorps chez un hôte réagissant spécifiquement avec ladite protéine CD.

Granted: 1999-11-16
Abstract: METHOD OF OPTIMIZING              ELECTRONIC PRICE LABEL SYSTEMS     A method of optimizing electronic price label (EPL) systems which employs a three-dimensional graph of retry levels in a transaction establishment.  The method includes the steps of determining locations of EPLs within the transaction establishment, determining locations of transmit and receive antennas that are used by a computer to communicate with the EPLs, determining retry levels for the EPLs, mapping the retry levels to locations within the transaction establishment, producing a three-dimensional graph of the retry levels within the area of the transaction establishment, and determining, from the graph, subareas within the area having retry levels above a predetermined maximum retry level.  Once the subareas having higher retry levels are determined, the locations of the transmit and receive antennas may be changed and/or interfering structures may be moved until the retry levels of the subareas are below the predetermined maximum retry level.
