Title: Procede et appareil de traitement de donnees sismiques
Inventor: MUIJS REMCO
IPC: G01V1/36
Filed: 2001-12-07
Abstract: L'invention concerne un procédé de traitement de données sismiques présentant plusieurs composantes acquises à un récepteur. Ce procédé détermine un schéma de décomposition adapté à utiliser. Ce procédé utilise l'existence de paires de composantes de champ d'ondes qui ne sont pas couplées l'une à l'autre. S'il n'existe pas de couplage physique entre la première et la seconde composante de champ d'ondes, celles-ci ne devraient pas arriver au lieu où se trouve le récepteur en même temps. Ce procédé consiste à décomposer une première partie, par exemple, une partie à l'essai, des données sismiques en diverses composantes de champ d'ondes, au moyen d'un schéma de décomposition initial. La première et la seconde composantes de champ d'ondes des données décomposées qui ne devraient pas être couplées l'une à l'autre sont ensuite sélectionnées et leur produit est déterminé. Puisque la première et la seconde composante champ d'ondes des données décomposées ne devraient pas être couplées l'une à l'autre, leur produit devrait être égal à zéro ou proche de zéro. Donc un produit très différent de zéro indique que le schéma de décomposition est imprécis.

IPC: G01R21/133
Filed: 2002-06-28
Abstract: An electro-optical, automatic reader (104) for enabling a consumer to view and manage power consumption through a browser (602). A sensor (210) attached to a bracket (202) is mounted to the outside cover (306) of a utility meter without modification of the meter (102) or removal of its housing. A data-collector (106) stores data obtained from the sensor (210) via a serial port which may also provide power for the sensor (210), thus avoiding use of a dedicated power supply. The data-collector (106) connects to a computer (110) which provides a centralized object through which to view and manage power consumption. The real-time and combined historic data can be used to forecast whether usage will fall above or below a predetermined usage level at the end of a given period of time. In response to a forecast exceeding the level, the computer (110) displays the appropriate graph in a red colored bar within a quantity vs. time chart. The computer (110) may control power consuming devices. A communication system (804) may be established to the system for remote management by the consumer or by the utility company (806) for its own billing and management purposes.

Abstract: Dans des dispositifs utilisés pour la conversion directe de chaleur en électricité, ou vice versa, connus en tant que générateurs de puissance thermoélectriques, réfrigérateurs thermoélectriques et pompes de chaleur thermoélectriques, l'efficacité de la conversion d'énergie et/ou le coefficient de performance sont considérablement inférieurs à ceux de systèmes conventionnels à moteurs thermiques et/ou à compression de vapeur, à va-et-vient ou rotatifs, mettant en oeuvre certains fluides de refroidissement. L'efficacité de la conversion d'énergie de dispositifs générant de la puissance, par exemple, outre des températures de jonction froide et de jonction chaude, dépend également d'un paramètre connu en tant que facteur thermoélectrique de qualité Z=S?2¿.sigma./k, où S représente la puissance thermoélectrique, .sigma. représente la conductivité électrique et k représente la conductivité thermique du matériau qui constitue les thermocouples, ou branches, de type p et/ou de type n de ces dispositifs. Afin d'obtenir une augmentation considérable de l'efficacité de la conversion d'énergie, il est nécessaire d'avoir un facteur thermoélectrique de qualité de l'ordre de 10?-2¿K?-1.¿ou plus. On peut raisonnablement espérer qu'un tel ordre de grandeur, pour le facteur de qualité, puisse être obtenu avec une composition de matière comprenant du magnésium, du silicium, du plomb et du baryum, et éventuellement comprenant un ou plusieurs matériaux de dopage supplémentaires.
