Abstract: The invention concerns a method using an image guide consisting of several thousands of optical fibers, an excitation signal being emitted by a source, deflected and injected by turns into the optical fibers of said guide, each excitation point of the tissue in the fiber output emitting in return a fluorescence signal collected by said fiber, then detected and digitized to form an image element. According to a first aspect of the invention, the method provides for the focussing of the beam in the fiber output to excite a subsurface plane to produce a confocal image. According to a second aspect, the method provides for the production of a divergent beam in the fiber output capable of exciting a micro-volume of the tissue from the surface. The invention is characterized in that the method consists in deflecting the excitation signal at a speed corresponding to acquisition of a number of images per second sufficient for real time use and in detecting the fluorescence signal at a detecting frequency corresponding to a minimum frequency for sampling the fibers one by one. The invention enables in vivo, in situ and real time imaging.

Abstract: L'invention concerne des méthodes pour évaluer les propriétés d'un matériau. Dans une première méthode, on calcule la vitesse d'une onde de contrainte ou d'une onde sonore en mesurant le temps de vol de l'onde de contrainte ou de l'onde sonore induite dans le matériau. La résonance du matériau est également mesurée après un contact avec le produit de bois. On calcule une vitesse distincte de l'onde sonore dans le matériau au moyen de mesures de résonance. Une comparaison des vitesses fournit une indication de l'homogénéité des propriétés du matériau. Les propriétés peuvent concerner, par exemple, la rigidité, la force, les divers gradients ou autres propriétés analogues. Dans une deuxième méthode de la présente invention, la vitesse calculée selon la méthode du temps de vol peut être utilisée comme guide pour déterminer une fréquence fondamentale pour l'onde de contrainte dans un matériau et la vitesse résultante. Le matériau peut être, par exemple, un bois, un métal, une matière plastique ou analogue.

Title: Mechanical flotation device for reduction of oil, alkalinity and undesirable gases
Inventor: CHEN JAMES C T
IPC: C02F1/40
Filed: 2006-03-02
Granted: 2012-10-23
Abstract: A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water. The vessel raises the pH of the water and reduces the lime requirement for subsequent lime softening. The vessel receives the water containing the first gas and passes the water through a series of gasification chambers. Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.
