Abstract:
L'invention concerne le domaine des techniques de détection d'une anomalie dans un signal de mesure issu d'un nœud observé Y d'un réseau. Le réseau peut plus particulièrement comprendre une structure arborescente comprenant, outre le nœud observé Y, une pluralité de nœuds non-observés Z 1 , Z 2 ,... Z p connecté au nœud observé. L'anomalie à détecter est plus particulièrement susceptible de survenir au niveau des nœuds non-observés. L'invention consiste à exprimer le signal de mesure comme une somme de fonctions adaptatives de variables explicatives, chaque fonction déterminant un comportement attendu du signal de mesure en fonction d'une des variables explicatives et pouvant être adaptée aux observations successives du signal de mesure, pour détecter toute anomalie comme une adaptation d'au moins une des fonctions allant au-delà d'une limite acceptable.

Abstract:
In one embodiment, a system and a method involve receiving a raw signal collected by a sensor that pertains to a temporal trend, creating a reference signal of a known amplitude and frequency, adding the reference signal to the raw signal to form a modulated signal, decomposing the modulated signal to obtain a decomposed signal, and conducting time-frequency analysis on the decomposed signal to detect abnormal patterns.
Abstract:
L'invention concerne un procédé de correction de la mesure d'une tension aux bornes de sortie d'un capteur (2), le capteur étant assimilable à un ensemble comprenant un générateur (10) et une résistance série (8), chacune des bornes de sortie (B1, B2) étant respectivement reliée à une résistance de tirage (12, 14). Le procédé comprend: une étape préliminaire d'évaluation de la résistance série (Rcapt) du capteur, cette étape comprenant la mesure d'une première (respectivement deuxième) tension aux bornes de sortie lorsqu'une première (respectivement deuxième) tension de polarisation est appliquée sur chaque résistance de tirage, et l'évaluation de la résistance série à partir des première et deuxième tensions; et une étape de correction, à partir de la résistance série, d'une tension mesurée aux bornes de sortie du capteur afin d'en déduire une tension correspondante générée par le générateur.

Abstract:
A cognitive and/or motor skill Jesting system and method may include a processor that records respective time information for each of multiple positions of a display device that are traced during administration of a test, that determines speed and/or velocity values based on the recorded time information, and that outputs test result information based on the determined values. The test result information may be based on a comparison between a graphed curve of such values to an ideal curve. The positions may correspond to a path between displayed targets whose size and/or distance therebetween depend on past test performance. The system and/or method may output a change expected with a change to therapy parameters for a patient, where the expected change is determined based on changes which occurred in other patients having similar test results and therapy parameters as those of the patient.
