Patent CA-2286018-C (CA)
Inventor: CARSTENSEN KENNETH J
IPC: E21B47/18
Filed: 1998-04-07
Granted: 2008-02-12
Abstract: Cette invention se rapporte à un système et à un procédé qui permettent de communiquer à distance avec des outils fond de trou télécommandés dans un puits d'une installation de forage. A cet effet, on produit à la surface des impulsions de pression de forte énergie, qui sont dirigées dans le tubage et/ou dans l'espace annulaire, à un niveau tel qu'elles se propagent à travers une interface entre des zones à impédances très différentes, telles qu'une zone de gaz de niveau supérieur et un milieu fluide mobile de niveau inférieur descendant dans la région fond de trou désirée. Ces impulsions de pression, que l'on produit en orientant le long du trajet de confinement longitudinal une impulsion de pression ayant initialement des bords d'attaque et de fuite à angle aigu, atteignent la région fond de trou sous la forme de perturbations physiques, lesquelles forment un modèle discernable qui peut être détecté par un ou plusieurs transducteurs réagissant à l'énergie. Grâce à des combinaisons de ces signaux, un ou plusieurs dispositifs de commande séparés peuvent être actionnés à distance. Ce système évite la nécessité de recourir à des connexions physiques ou électriques, et en même temps, réduit considérablement les risques d'actionnement accidentel.

Abstract: An apparatus for controlling a hybrid vehicle having an internal combustion engine and an electric motor as driving sources for the vehicle, in which when it is detected that an air-fuel ratio of a supply air-fuel mixture to the engine changed to the lean side value (S44 - S46), the electric motor (2) is made operative as a motor in order to assist an output of the engine just after the detection (S47, S48). When it is detected that the air-fuel ratio of the supply air-fuel mixture changed to the rich side value (S44, S52, S53), the electric motor (2) is made operative as a generator for the purpose of the regeneration braking just after the detection (S54, S55). An output torque difference of the engine, therefore, when the air-fuel ratio of the supply air-fuel mixture changes can be sufficiently compensated without a time delay.

Abstract: A method and apparatus for radiography, and especially for planar beam radiography, and also a detector for detecting incident radiation. In the method and apparatus, wherein X-rays (9) are emitted from an X-ray source (60), the X-rays are formed into a planar beam and are transmitted through an object to be imaged (62), and the X-rays transmitted through said object (62) are detected in a detector (64). The detector (64), which detects incident radiation is a gaseous parallel plate avalanche chamber, including electrode arrangements between which a voltage is applied for creating an electrical field, which causes electron-ion avalanches of primary and secondary ionization electrons released by incident radiation. The detector (64) is oriented, in relation to the incident radiation (9), so that the radiation enters sideways between a first and a second parallel plate, between which the electrical field is created. Electrical signals induced by said electron-ion avalanches are detected in at least one detector electrode arrangement, including a plurality of detector electrode elements arranged adjacent to each other, each along a direction being essentially parallel to the incident radiation. Pulses from each detector electrode element are processed in processing electronics, for obtainingvalues for each pixel corresponding to the respective detector electrode element.
