Abstract: La présente invention concerne le problème général de la détection en sonar ou en radar Elle s'intéresse en particulier à la détection initiale d'un signal d'intérêt dans un flot de données correspondant au signal reçu par un tel équipement. Cette détection initiale est transmise aux équipements chargés d'effectuer le pistage des objets d'intérêt ayant fait l'objet d'une détection. Le procédé selon l'invention considère qu'un signal d'intérêt est caractérisé par un modèle d'état x(t) à valeurs dans un ensemble fini {x1, ..., xN}, auquel correspond un ensemble fini {.omega.1, ..., .omega.N} de N valeurs d'une variable d'observation .omega., caractéristique de ce signal. Pour détecter la présence d'un signal d'intérêt le procédé calcule simultanément de deux façons différentes la valeur d'un critère de détection .LAMBDA.n(t): - comme une fonction du produit de la probabilité Pn de l'état xn, et du rapport des probabilités conditionnelles p1 et p0 de la donnée y(t, .omega.n) contenant le signal, en l'absence et en présence de signal, - comme une fonction du produit d'une des N valeurs du critère calculées à l'instant précédent t - 1, de la probabilité de transition Pn,m entre l'état xm pour lequel cette valeur a été calculée à l'instant t-1 et l'état xn considéré, et du rapport des probabilités conditionnelles p1 et p0 de la donnée y(t, .omega.n) en l'absence et en présence de signal, la plus grande des deux valeurs calculées est attribuée au critère de .LAMBDA.n(t) qui est alors comparé à un seuil de détection.

Title: A network implemented content processing system
Inventor: MOSS NICHOLAS IAN
IPC: H04L29/06
Filed: 2006-11-07
Granted: 2016-08-30
Abstract: In the present invention, a data processing device for processing streams of network borne data includes content inspection logic configurable to perform pattern matching functions on a received content stream and output match data, and a microengine for executing computer coded instructions, the microengine being coupled to the content inspection logic for configuring the pattern matching function of the content inspection unit in respect of a particular processing job for the received content stream and for processing the content stream in dependence on the match data. The microengine is adapted to reconfigure dynamically the content inspection logic in dependence on the match data thereby to modify the pattern matching function performed by the content inspection logic on the content stream during the course of a processing job. The present invention provides a novel architecture and method for processing content as it flows through a network. The processing of content includes parsing, analysing, modifying and controlling the delivery of a content stream using a number of pattern matching techniques. Importantly, the present invention makes it possible to adjust the parameters of the pattern matching search as the search progresses through the content stream.

Abstract: A catheter assembly and method is disclosed which comprises a catheter having a coating on at least a part of its length intended to produce a low- friction surface on the catheter when treated with an activating substance in the form of a vapor. The catheter assembly also includes a catheter package forming an interior space divided by a gas permeable, liquid impermeable barrier into a first cavity and a second cavity. The first cavity of the catheter package accommodates the catheter therein and the second cavity accommodates at least a quantity of liquid in its liquid phase therein. The liquid in the second cavity can change phase into a vapor capable of passing from the second cavity, through the barrier, and into the first cavity where the vapor can activate the coating. As a result, the vapor produced when the liquid changes phase causes the coating on the catheter to be activated to thereby produce the low-friction surface on the catheter so it is ready-to-use when it reaches the end user.

Granted: 2012-04-03
Abstract: An offshore universal riser system. A riser system includes a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device releasably secures the valve module in the flow passage. A method of constructing a riser system includes the steps of installing the valve module in the flow passage, and installing at least one annular seal module in the flow passage. The annular seal module is operative to prevent fluid flow through an annular space between the riser string and a tubular string positioned in the flow passage. Drilling methods include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, is dimensioned for installation through a rotary table.

Abstract: A method of controlling an electric synchronous machine (2) having a stator and a moving part comprises the following steps: operating the machine (2) with a deceleration moment (M p) so that a moving part speed of the machine is reduced, monitoring the moving part movement of the machine, and upon detection of a direction reversal or a speed (v) of the moving part of approximately zero, a transition to a holding mode is effected, adjusting at least one electric supply variable (I; i u, i v, i w) of an electric stator system of the machine such that, at the beginning of the holding mode, an effective internal moment (M B) of the machine is formed that is reduced with respect to the deceleration moment (M p). The electric supply variable (I; i u, i v, i w) is adjusted in this manner until, with movement of the moving part and influence of an external moment (M A) acting on the machine, a stable equilibrium of moments between external moment (M A) and internal moment (M B) of the machine is established.
