Granted: 2003-07-22
Abstract: Détection dun terminal sans fil emporté depuis un site. Dans un premier mode de réalisation, une station de base est attribuée à chaque sortie du site. La station de base utilise une antenne directionnelle qui communique uniquement avec des terminaux sans fil au sein de la zone de sortie. Lorsquun terminal sans fil entre dans la zone de sortie et senregistre auprès de la station de base, la station de base transmet les informations denregistrement à un système de commutation sans fil qui amorce immédiatement un appel téléphonique à lutilisateur du terminal sans fil pour linformer que son terminal sans fil na pas été rendu. En variante, dans un troisième mode de réalisation, après enregistrement du terminal sans fil, la station de base plutôt que le système de commutation sans fil amorce un appel téléphonique à lutilisateur du terminal sans fil pour linformer que son terminal sans fil na pas été rendu. Dans un deuxième mode de réalisation de linvention, un signal de transmission séparé des fréquences utilisées pour une communication voix et données par le système de commutation sans fil est utilisé pour alerter le terminal sans fil du fait que le terminal sans fil se trouve dans une zone de sortie. Le terminal sans fil est réactif à cette alerte pour initier un appel au système de commutation sans fil afin dinformer le système de commutation sans fil de ce fait. Le système de commutation sans fil alerte alors lutilisateur via le terminal sans fil.

Abstract: The invention is directed to an air spring system wherein an adequate carrying off of heat is ensured for a shock absorber (18) which is completely within an air spring (16) which includes a flexible member (4) and a roll-off piston (6). The interior spaces (12, 14) of the flexible member (4) and the roll-off piston (6) communicate with each other. In lieu of a conventional clamping plate, a funnel-shaped insert (22) is disposed between the flexible member (4) and the roll-off piston (6). The insert (22) surrounds the shock absorber (18) in such a manner that an annular nozzle-shaped narrow (23) results between the walls of the shock absorber (18) and the inner surface of the funnel-shaped insert (22). Openings (26) are disposed on the outer region of the insert (22). These openings (26) as well as the nozzle-shaped narrow (23) define a connection between the volume (12) of the flexible member (4) and the volume (14) of the roll-off piston (6). An air circulation (30) with an air flow along the wall of the shock absorber (18) results during spring compression and spring expansion.

Abstract: L'invention concerne des procédés pour mesurer la vitesse de prolifération et de destruction des cellules en mesurant la synthèse et/ou la destruction de l'acide désoxyribonucléique (ADN). Dans ces procédés, on utilise en particulier des marqueurs isotopes stables non radioactifs pour marquer de manière endogène l'ADN synthétisé par l'intermédiaire la voie de synthèse des nucléotides de novo dans une cellule. La mesure de la quantité de marqueur incorporé dans l'ADN donne une indication sur la prolifération cellulaire. La mesure de la diminution d'ADN marqué dans le temps donne une indication sur la destruction cellulaire. Dans ces procédés on n'utilise pas de radioactivité ou de métabolites potentiellement toxiques, et on peut les appliquer in vitro et in vivo. L'invention est par conséquent utile pour mesurer la vitesse de prolifération ou de destruction cellulaire chez l'homme, pour le diagnostic, la prévention ou le traitement de diverses pathologies dans lesquelles la prolifération et la destruction cellulaire interviennent. L'invention concerne en outre des procédés pour mesurer la prolifération ou la destruction de lymphocytes T chez un sujet infecté par le virus de l'immunodéficience humaine (VIH) et des procédés pour analyser la capacité d'un agent d'induire ou d'inhiber la prolifération ou la destruction cellulaires. L'invention porte encore sur des procédés pour mesurer la prolifération cellulaire dans une population proliférative, à la fois au moyen de marqueurs isotopes radioactifs et d'isotopes stables pour marquer l'ADN de manière endogène par l'intermédiaire de la voie de synthèse de novo des nucléotides.

Abstract: An expansible core shaft assembly adapted to retain a set of web spool cores in axially fixed positions while permitting rotational slippage of the web spool cores. The assembly may comprise a shaft defining at least one channel. An expansible bladder is retained in the channel and a set of first lugs and a set of second lugs are retained in the channel radially outwardly of the expansible bladder with first and second lugs mutually interspersed. Each lug has a bladder facing surface defining an indentation. The first lugs define a first indentation in a first position and the second lugs define a second indentation that is sufficiently distinct from said first position to reduce the effect that the radial position of each core stop has on the radial positions of its neighbors. In a separate embodiment the assembly may comprise a channel accommodating a first expansible bladder and a bracket positioned radially outwardly from the first bladder and defining a second channel, which accommodates a second bladder. Core stops are set into the second channel radially outwardly of the second bladder. The first and second bladders are independently expansible so that the core stops may be released for rearrangement independently of being retracted.

Granted: 2012-10-09
Abstract: A structure is chosen a priori, with one physical dimension (k) estimated from the exploration data and a second ( sigma ) estimated from the fluid production data. The model is optimized by iterative application of an inversion of at least one of the physical dimensions, which are related by a combination function. The final model at least satisfies the combination of the two dimensions. The iterative optimization involves a simultaneous iteration of the first and second physical dimensions with optimization of a global cost function J(K,  sigma ) of the two dimensions. The global cost function is the sum of terms measuring the spacing between the points of each model and the data obtained by measurement or observation or the corresponding dimension and the spacing taking into account the combination of the two dimensions. Each model is optimized by minimizing the objective function by determining its exact gradient using the adjoining state method. The production data are measured in the shaft through the underground area and the exploration data are the seismic data captured by seismic receivers in response to waves transmitted through the formation. The first physical dimension is the permeability of the medium and the second is the impedance of the medium relative to the waves.

Abstract: Printing plates for all-over printing of large areas by the intaglio printin g proc- ess, a method for producing the printing plates and data carriers, in particular bank notes, with large-area printed images produced by the intaglio printing process are proposed. Flawless inking is ensured by providing partitions in the engravin g of the printing plate which rise up vertically from the base of the engraved area a nd have at least a height of 50% of the engraving depth. The partitions largely prevent ink from being wiped out of the engraved areas when ink is wiped off the printing pla te sur- face. This permits a large printed area to be covered all over with ink laye rs on a data carrier. By special arrangement and design of the partitions one can al so pro- duce fine structures in the printing area which are recognizable only with magnifying aids depending on the selected distances between the partitions.
