Abstract: A simple, compact, and low-cost analog-to-digital converter utilizes low-resolution and high-resolution conversion paths for precision voltage measurements. A first conversion made using a comparatively low resolution ADC is used to predict the reference voltage to one input of a null detector that receives the input voltage on another input, and effectively magnifies the voltage difference between its inputs. In a preferred embodiment, the duty cycle of a pulse-width modulator is adjusted to precisely adjust the reference voltage to provide a nulled (or near null) reading from the null detector. A low resolution ADC then converts the voltage from the null detector, which when added to the reference voltage, yields a final reading with 18-bit to 22-bit accuracy. The preferred embodiment is implemented to read the output from a pressure transducer and employs a binary search technique to rapidly adjust the duty cycle of the pulse-width modulator. The system utilizes a single ADC which is multiplexed between the low-resolution, high-speed reading and high-resolution, low-speed reading of the fully settled output of the null detector.

Abstract: Semiconductor layers (1) define a PIN superstructure, the intrinsic part (I) of which comprises a series of layers (SL) forming quantum wells; it is capable, within a spectral range, of optical absorption dependent on the electric field. Working light, lying within the said spectral range, is admitted into the series of quantum-well layers, this light photocreating, in the said series of layers, electron-hole pairs by photon absorption. The number, types and geometries of the layers of the said series of layers (SL) are chosen so that the said series of layers produces a superlattice capable, on the one hand, of the Wannier-Stark effect and, on the other hand, of generating, at rest, a self-established electric field because of the potential difference naturally set up at its terminals by the PIN superstructure. The combined effect, on the photocreated electron-hole pairs, of the said Wannier-Stark effect and of the said electric field self-established at rest generates a self-amplifying effect of the absorption variations of the said series of layers (SL). This provides an "all optical" bistable effect without requiring recourse to an external electrical circuit. <IMAGE>

Abstract: Un système de communications à fibres optiques génère des signaux optiques de différentes longueurs d'ondes sur une fibre optique (1, 2) possédant une longueur d'onde de dispersion nulle. Des éléments électriques (36-39) de compensation de dispersion compensent indépendamment des signaux optiques possédant des longueurs d'ondes qui diffèrent de la longueur d'onde de dispersion nulle pour la dispersion dans la fibre optique. La limitation des signaux radio-électriques, destinés à moduler un dispositif émettant de la lumière ou un laser (21-24) générant des signaux à une longueur d'onde qui diffère de la longueur d'onde de dispersion nulle inférieure à une octave de fréquence, permet une distorsion d'harmoniques du second ordre résultant de la dispersion dans la fibre à filtrer au niveau d'une station réceptrice. Ce système de communications à fibres optiques peut compter une voie de transmission inverse.

Abstract: Procédé et appareil de commande d'un système amplificateur de puissance à précompensation au moyen d'une technique d'étalement de spectre afin de couvrir un ou plusieurs signaux de commande, et de l'injection d'un signal composite en un point approprié dans le système amplificateur à précompensation afin de réduire la distorsion. L'importance de l'étalement de la largeur de bande est déterminée par l'importance du gain de traitement nécessaire au processus de remappage et de la réponse temporelle nécessaire au système. Après le remappage du spectre étalé à la sortie du système, les signaux de commande subissent une corrélation dans un filtre corrélateur adapté et le résultat sert à commander, à l'aide de coordonnées polaires ou cartésiennes, l'injection, en opposition de phase, de la distorsion extraite dans le signal de sortie de l'amplificateur à précompensation.
