Abstract: Circuit de détection de capture pour un stimulateur cardiaque implantable. Un signal détecté par une électrode dans le coeur à la suite de l'application d'une impulsion de stimulation est amplifié, filtré par filtrage passe-bande et passe-haut, rectifié, intégré sur la durée d'une fenêtre choisie de temps qui commence au bout d'un laps de temps choisi après l'application de l'impulsion de stimulation, et appliqué à deux comparateurs ayant des valeurs de référence différentes. Si le signal intégré dépasse la première valeur de référence, la sortie du premier comparateur va vers le haut. Si le signal intégré dépasse la seconde valeur de référence, le second comparateur va vers le haut. Si les deux comparateurs restent vers le bas, ils indiquent alors la non capture. Si le premier comparateur va vers le haut et que le second comparateur reste vers le bas, cela indique la capture. Si le second comparateur va vers le haut, cela indique une contraction intrinsèque. Il est possible d'élargir la fenêtre d'intégration pour distinguerla capture de la contraction intrinsèque.

IPC: H04B1/707
Filed: 1996-12-12
Granted: 2008-04-01
Abstract: L'invention concerne les récepteurs de positionnement par satellite. Pour réduire l'effet néfaste des trajets réfléchis sur la mesure de position GPS qui ne devrait prendre en compte que le trajet des signaux radiofréquence en ligne directe, on propose selon l'invention un procédé permettant par simple calcul d'extrapolation d'éliminer l'influence des multitrajets. On effectue des mesures par corrélation avec quatre codes pseudo-aléaoires E1, E2, L1, L2 répliques d'un code reçu d'n satellite. On effectue un premier ensemble de mesures d'énergies de corrélation et de temps reçu avec les codes E1, L1 correspondant à une avance et un retard d par rapport à un code ponctuel, et un deuxième ensemble de mesures avec les codes E2, L2 correspondant à une avance et un retard k*d (k différent de 1 et de 0). Par extrapolation linéaire, on en déduit les mesures pour k = 0, qui correspond au cas où les multitrajets n'ont pas d'effet. L'invention peut être mise en oeuvre avec une seule boucle d'asservissement de code pseudo-aléatoire ou deux boucles indépendantes.

Abstract: A gastro-laryngeal mask (10) features softly compliant construction of the distal half of the mask (13), wherein the mask (13) is of generally elliptical configuration, with an inflatable peripheral cuff (18) to seal and support the mask (13) around the laryngeal inlet (17). A back cushion (25) is inflatable to engage the back wall of the pharynx and thus to forwardly load the peripheral cuff seal (18) to the laryngeal inlet (17). An evacuation tube (23) for external removal of a possible gastric discharge completes an evacuation or discharge passage (26) contained within the mask (13) and opening through the distal end of the peripheral cuff (18). Special provision is made for assuring integrity of the discharge passage (26) within the flexible distal half of the mask (13), i.e., assuring against collapse of the distal-end half of the softly compliant evacuation tube (26) in the distal region of the mask (13), such that inflation of the mask (13) does not compromise viability of the evacuation tube (23) by compressing softly compliant material of the evacua- tion tube (23) during periods of mask (13) inflation. The special provision also favors such collapse of the mask (13) when deflated as to provide a leading flexible edge for piloting a safe and correct advancing insertional advance of the deflated mask (13) in the pa- tient's throat (15), in avoidance of epiglottis (16) interference and to the point of locating engagement in the upper sphincter of the oesophagus (24).
