Abstract: The MOS cell with adjustable threshold voltage is a cell of the memory type, which can be programmed and erased electrically through charge accumulation by the tunnel effect under a floating gate. To obtain a circuit with adjustable threshold voltage, the cell is firstly "programmed" to zero in such a way that all the charges which may have accumulated are cleared, and then "erased" with source earthed, drain taken to the high potential and control gate taken to the potential desired for the threshold voltage VT of the circuit. At the end of this phase the threshold voltage is adjusted. Application in particular to circuits requiring, in MOS technology, precise voltage references, circuit of the detector or analogue-digital convertor type. <IMAGE>

Abstract: The invention relates to a circuit for controlling the variation in power applied to an electric motor. To control the motor, use is made of a field-effect transistor Q in series with the motor M, and a regulating potentiometer POT. However, to prevent the current in the motor, for a given position of the potentiometer slider, from depending overly on the characteristics of the transistor Q, use is made of a control through a current mirror setup (transistors T1, T2, resistors R13 to R16) such that the drain-source voltage of the field-effect transistor duplicates the voltage delivered by the potentiometer slider. <IMAGE>

Abstract: L'invention concerne un système implantable et un procédé de défibrillation/rétablissement du rythme sinusal, comprenant une électrode dotée de segments électroconducteurs discrets (92), (94), et (96). Lesdits segments conducteurs sont isolés électriquement les uns des autres et sont connectés électriquement à une unité de défibrillation/rétablissement du rythme sinusal (25). Un bloc d'impulsions électriques est créé et haché en une pluralité de segments d'impulsions discrètes par ladite unité de défibrillation/rétablissement du rythme sinusal (25), puis il est appliqué à l'électrode de sorte que chaque segment conducteur reçoit une impulsion électrique particulière affectée à partir de la série d'impulsions. On réduit ainsi la concentration de gaz émise par le courant ionique produit par une impulsion de défibrillation de haute énergie, et plus d'énergie est acheminée au coeur, réduisant ainsi l'entrée d'énergie nécessaire dans l'électrode. Ladite électrode peut être plane ou se trouver dans une configuration d'électrode de cathéter (90).

Abstract: Sont présentés un appareil et une méthode pour effectuer la détermination photométrique du contenu d'un échantillon, comme les caractéristiques d'absorption d'un échantillon de sérum sanguin. Les améliorations des techniques permettent de prendre des mesures après une période de chauffe réduite et compensent les variations de l'intensité de la lampe pendant la période de prise de mesures. Un circuit de retour existe entre un photodétecteur de référence et la source lumineuse et permet à l'intensité de la source lumineuse de s'approcher de manière asymptotique d'une valeur finale stable dans une courbe exponentielle légère. Un système de traitement du signal traite les sorties des photodétecteurs de référence et d'échantillonnage prises à différents moments afin de compenser les variations de l'intensité de la source pendant toute la période où il y a des données de sortie. De plus, le photomètre permet le mélange de la fréquence résonnante du contenu de la cuvette, lorsqu'elle se trouve dans le photomètre, en faisant vibrer à sa fréquence vibratoire tout l'assemblage optique dans lequel est placé la cuvette. Un microprocesseur de commande de la routine de recherche est utilisé pour déterminer la fréquence résonnante de l'assemblage optique qui est facilement recalculable chaque fois qu'il se produit un changement des dimensions ou de la masse de l'assemblage optique, ou du contenu de la cuvette.
