Abstract: The invention concerns structural integrity assessment apparatus for determining stress concentration zones in a structure, such as a pipeline. The apparatus allows particularly to detect defects in buried pipelines using magnetometric surveying where anomalies in the magnetic field around the pipelines are detected. The apparatus has a plurality of triaxial magnetic field sensors, each sensor being arranged to measure magnetic field components in a plurality of directions. A support is provided to maintain said sensors in a predetermined relative spacing and orientation. The support is moveable relative to a structure under assessment in use and may be portable. Three or more magnetic field sensors are provided which may be arranged in a linear, two-dimensional or three-dimensional array. The apparatus may include position determining means, such as a global positioning system (GPS), so that stress concentration zones can be located on the structure.

Abstract: Whereas traditional fitness systems are based on training for energy (endurance) and its time-derivative, power (strength), using the concept of distance and its time-derivatives (speed, acceleration, etc.), the invention uses time-integrals of energy or distance (or angle, or the like). For example, a chinup or pullup bar hanging from a chain or rope, is used as the steering wheel in a video game, so as to simultaneously require dexterity and fine motor control while performing an exercise such as chinups or pullups.

Abstract: L'invention se rapporte à des procédés et à des systèmes destinés à récupérer des hydrocarbures de l'intérieur de formations dans lesquelles des réservoirs contenant des hydrocarbures sont séparés les uns des autres par une strate naturelle d'obstruction d'écoulement de fluide. Par rapport aux réservoirs, la strate empêche ou bloque l'écoulement de fluide vertical dans la formation. Des trous latéraux dévient de longueurs de puits d'injection et de production le long du point où ils s'étendent dans une direction horizontale. Ces trous traversent, vers le haut, la formation pour couper la strate et créer un ensemble de voies d'écoulement de fluide dans la strate. Dans une direction latérale perpendiculaire à la direction horizontale des puits, les trous latéraux partant du puits d'injection traversent la strate à l'intérieur du point où les trous latéraux partant du puits de production traversent la strate. Une communication fluidique établie par les trous limite l'écoulement à contre-courant par les trous lors de processus qui reposent sur des techniques telles que l'évacuation par gravité.
