Abstract: L'invention concerne des dispositifs, des systèmes et des procédés qui facilitent la mise en place d'un dispositif de traitement de l'anneau valvulaire et permettent ainsi d'améliorer le traitement de celui-ci. Les procédés de l'invention consistent généralement à: avancer un dispositif de distribution d'ancrage dans le système vasculaire du patient jusqu'à un endroit précis au niveau du coeur pour traiter l'anneau valvulaire; mettre en contact le dispositif de distribution d'ancrage avec une longueur de l'anneau valvulaire; expulser du dispositif de distribution d'ancrage une pluralité d'ancrages couplés et les fixer à l'anneau valvulaire; et enfin, tirer les ancrages ensemble pour appliquer un resserrage circonférentiel à la valvule annulaire. Quant aux dispositifs de l'invention, ils comportent généralement un cathéter allongé doté d'au moins un élément tendeur et d'au moins un actionneur tendeur qui permettent de déformer une partie distale du cathéter pour qu'elle épouse les contours de l'anneau valvulaire. Ce dispositif cathéter peut servir à naviguer dans un espace sous-annulaire en-dessous de la valvule mitrale pour faciliter la mise en place d'un dispositif de distribution d'ancrage.

Abstract: The invention relates to a debarking mechanism (1) for the decortication or pretreatment of logs (2) for separately performed final debarking and for the discharge of at least some of the bark removed from a wood stream passing through the debarking mechanism, the said debarking mechanism comprising a number of rotatable debarking shafts (3, 3') extending parallel to an advancing direction (A) of the logs (2) to be fed therethrough, which are provided with a number of teeth (4) extending beyond the circumferential surface of the shaft (3, 3'). The debarking shafts (3, 3') are arranged relative to each other in such a way that the logs (2) being processed perform a rotary motion (C) in the debarking mechanism, in which motion the logs (2) are forced in their turn, by the effect of the rotary motion (5) of the debarking shafts (3, 3'), into the upper position, from which they roll down into the lower position on top of the other logs (2) in the debarking machine (1). At least the uppermost debarking shaft (3'), is moved sideways towards the inner part (6) of the debarking mechanism (1) in such a way that the said debarking shaft directs an impact effect on logs (2) colliding with it and moved by the debarking shafts (3) located in a lower position, due to the effect of which the direction of movement of the logs (2) having collided with the said debarking shaft will change in such a way that when dividing the movement into a horizontal and a vertical component, the horizontal component of the movement will point towards the inner part (6) of the debarking mechanism (1). The circumferential speed of the debarking shaft is selected to be the greater the higher the debarking shaft (3, 3') is positioned. A free passage (7) is arranged for the bark passing over the debarking shaft (3').

Abstract: A method and apparatus for measuring drowsiness particularly in vehicle operators measures the amplitude to velocity ratio for eyelids closing and opening during blinking as well as measuring duration of opening and closing.  The average values for the amplitude to velocity ratios for opening and closing are weighted and added to give a drowsiness measure that is compared to a scale of drowsiness based on data collected from alert and drowsy subjects. Other eye movements can be used in the weighted algorithm. The scale of drowsiness predicts the onset of drowsiness levels that render an operator unfit to continue.

Title: Methods of limiting leak off and damage in hydraulic fractures
Inventor: HUTCHINS RICHARD D
IPC: C09K8/80
Filed: 2007-09-06
Granted: 2011-11-29
Abstract: Methods for treating a formation penetrated by a wellbore which improves fluid loss control during treatment. In some aspects, the treatments include preparing an aqueous fluid including one or more water inert polymers and an optional viscosifier, injecting the aqueous fluid into the wellbore at a pressure equal to or greater than the formation's fracture initiation pressure, and thereafter injecting into the wellbore a proppant laden fluid at a pressure equal to or greater than the formation's fracture initiation pressure. The water inert polymer may be a polymer such as an emulsion polymer or a latex polymer. Some methods of the invention use a fluid which may have a normalized leak off coefficient (C w/sqrt(K)) equal to or less than about 0.0022, 0.0014, or 0.0010. A conventional fluid loss additive may or may not be used in conjunction with the treatment fluid and/or the proppant laden fluid. The water inert polymer may or may not substantially enter formation pores. In another aspect, methods for reducing matrix damage to a formation during a treatment operation include preparing an aqueous treatment fluid formed of at least one water inert polymer, and injecting the fluid at a pressure equal or greater than the formation's fracture initiation pressure.

Abstract: The present invention provides a guidance, navigation, and control method and system for an underground mining vehicle that allow said vehicle to be taught a route by a human operator and then have it automatically drive the route with no human intervention. The method works in three steps: teaching, route profiling, and playback. In the teaching step the vehicle is manually driven by a operator (or using tele-operation whereby the operator views a screen displaying live views from vehicle-mounted cameras and using remote controls) along a route which can consist of an arbitrary sequence of maneuvers including tramming forwards, switching directions, tramming backwards, turning, or pausing movement. During this phase raw data from vehicle-mounted sensors including odometric sensors and rangefinders are logged to a file throughout teaching for later processing. During the (offline) route profiling step, the raw data in the log file are processed into a route profile including a vehicle path, a sequence of local metric submaps located along the path, and a profile of desired speed as a function of distance along the path.  During the playback step, the vehicle automatically repeats the route that was taught during the teaching phase, as represented by the route profile. This is accomplished by first determining where the vehicle is on the route using a localization method which uses the odometric and laser rangefinder sensors and the local metric maps to determine the vehicle location. A steering control method adjusts the vehicle's steering to ensure it tracks the intended path. A  drive control method adjusts the vehicle's speed accordingly and safety method ensures the vehicle stops in the event that an obstruction is on the vehicle's intended path.
