Title: Procede et appareil d'analyse spectrale
Inventor: JIN DONGXING
IPC: G01R23/16
Filed: 2002-06-10
Abstract: Cette invention concerne un détecteur de signaux et un procédé d'analyse spectrale, lequel détecteur de signaux est chargé de mesurer la puissance d'un ou plusieurs canaux d'un signal électrique ou optique. Chacun des canaux peut comporter une seule tonalité de modulation. Un processeur de signal numérique (DSP) effectue des transformées de Fourier discrètes (TFD) sur le signal. Les bandes de fréquence d'intérêt qui contiennent une tonalité nécessitant une détection sont traitées. Des couches supérieures d'intégrations cohérentes sont formées sur des bandes qui n'ont pas détecté une tonalité comportant une résolution appropriée à une mesure de puissance. Les couches supérieures d'intégrations cohérentes sont formées selon un procédé consistant à recueillir des données supplémentaires et à effectuer une intégration cohérente. D'autres intégrations cohérentes à couches supérieures sont effectuées jusqu'à ce que toutes les tonalités de modulation aient été détectées avec une résolution appropriée ou jusqu'à ce qu'on obtienne une latence de détection maximale. Le fait de traiter uniquement les bandes d'intérêt et d'effectuer des intégrations cohérentes à couches supérieures uniquement sur les bandes d'intérêt qui nécessitent une résolution plus haute offre une latence de détection variable, une utilisation efficace de la mémoire et des calculs et des mesures de puissance en temps réel.

Title: Passive heat removal from containment
Inventor: GOU PERNG-FEI
IPC: G21C9/004
Filed: 1990-03-15
Abstract: ABSTRACT OF THE DISCLOSURE   A suppression chamber in a nuclear reactor containment includes a heat exchanger disposed in a gas space above water in the suppression chamber.  A gravity-driven pool contains a supply of make-up water that is gravity fed to the heat exchanger through a conventional level-maintaining valve such as a float valve.  A top header in the heat exchanger includes a free surface area for permitting separation of steam from water, thereby permitting venting of vapor only, while retaining the liquid coolant in the heat exchanger.  A downcomer tube permits return of excess water to a lower location for further use in the heat exchanger.  The heat exchanger is normally sealed, whereby internal surfaces in the heat exchanger require only a small amount of low-volatility corrosion inhibitors to prevent corrosion on internal surfaces thereof. Locating the heat exchanger in the gas space in the suppression chamber reduces the amount of corrosion on its external surfaces.  Condensate drips from the heat exchanger into the water below to disturb the water and thus enhance mixing and promote heat removal.

Patent CA-2021514-A1 (CA)
Title: Constrained-stochastic-excitation coding
Inventor: SHOHAM YAIR
IPC: G10L25/93
Filed: 1990-07-19
Abstract: In CELP coding, stochastic (noise-like) excitation is used in exciting a cascade of long-term and short-term all-pole linear synthesis filters. This approach is based on the observation that the ideal excitation, obtained by inverse-filtering the speech signal, can be modeled for simplicity as Gaussian white noise. Although such stochastic excitation resembles the ideal excitation in its global statistical properties, it contains a noisy component that is irrelevant to the synthesis process. This component introduces some roughness and noisiness in the synthesized speech. The present invention reduces this effect by adaptively controlling the level of the stochastic excitation. The proposed control mechanism links the stochastic excitation to the long-term predictor in such a way that the excitation level isinversely related to the efficiency of the predictor. As a result, during voiced sounds, the excitation level is considerably attenuated and the synthesis is mainly accomplished by exciting the short-term filter with the periodic output of the long-term filter. This reduces the noisiness, enhances the pitch structure of the synthesized speech and its perceptual quality.
