Title: Geodesic device comprising a laser source
Inventor: BRAUNECKER BERNHARD
IPC: H01S5/14
Filed: 2004-09-17
Abstract: A laser source (2) is used in a geodesic device (1) to improve the emission of laser light, in which the laser diodes (2b) emitting multimodal radiation are influenced by a mode-selective component (2d) such that the laser radiation emitted by the laser source (2) has monomodal character. An edge emitter (2b) or a vertical semiconductor emitter with an external cavity, is hence used, in which a mode selective component (2d) is arranged, for example, a monomode fibre or resonator mirror, which has the effect of a mode-selective resonator construction. Components with negative dispersion can be used for pulse compression to compensate for the greater pulse duration generated by the lengthened cavity.

Patent CA-2541951-A1 (CA)
Inventor: RORATO REMY
IPC: G06T19/20
Filed: 2006-04-05
Abstract: The invention is directed to a method of computer-aided design of a modeled object (10) having several faces. The method comprises a step of identifying, for each of said faces of the object (10), at least another of said faces related to said face according to geometrical criteria. Faces are thereby marked as connected. This is part of the "topology preprocessing" needed for implementing subsequent steps of the method. The method also comprises a step of computing a plurality of points forming a tessellated representation of each of said faces. Based on this tessellation, the method characterizes critical regions by determining and storing data representative of an intersection between a three-dimensional geometrical figure (touching a given face) and a face related to said face, according to the identifying step above. The step of determining whether intersections occur is carried out for each point of the tessellated representation of a face and for each face of the object. Then, as part of a "frontier extraction" general step, the method computes frontiers (delimiting zones where surface recomputation would occur) between points according to their respectively stored data and determines zones according to the determined frontiers.    Preferably, a progressive zone determination method is implemented; notably comprising detection of zones comprising fillet or round-like, step-like and wall-like sections, by calling a suitable coupling routine. Finally, surfaces (12, 14, 140, 142, 145, 148, 150) are recomputed according to the determined zones.

Abstract: An organic (or organo-halogenic) product is mixed with sufficient water to at least satisfy the stoichiometric ratio of carbon to oxygen atoms (and of hydrogen to halogen atoms). The mixture is mixed with plasmagenous gas in an inductive plasma torch coil (6) to decompose it to atoms (7). The gases are mixed with air and/or oxygen (8) for a second thermal destruction without energy input. At least part of the gases from the mixing device are recombined by cooling (10) and the destroyed gases are ejected (20). The mixture of at least one organic or organo-halogenic product with water is introduced at the level of the coil of the inductive plasma torch in droplet form if the product is liquid or powder and in gaseous form if the product is gaseous. The mixing device (8) is a venturi. An additional cooling stage (17) allows the recombined gases from the first cooling stage to exchange heat with the surrounding environment. There is an analysis stage (12) for the gases leaving the recombination stage and a stage of regulating the pressure of the gas using a vacuum pump. At least one chemical treatment stage, selected from dehalogenisation (14), de-oxidation of nitrous oxides (16) and desulfurisation, is included. A spray (13) of water on the gases is carried out before the chemical treatment stage. An independent claim is included for a device to carry out this process, comprising an inductive plasma torch; means of introducing plasmageous gas into the torch; means of introducing a mixture of water and at least one organic or organo-halogenic product into the torch; a reaction chamber which allows thermal destruction of the gases leaving the inductive plasma torch; a device for mixing the gases leaving the reaction chamber; means of introducing air and/or oxygen into the mixing device and means of allowing recombination by cooling of at least part of the gases from the mixing device. The inductive torch is connected to the reaction chamber, which is connected to the mixing device, which is connected to the recombination device. The device includes common means (11) of cooling the inductive plasma torch, the reaction chamber, the mixing device and the recombination device. The reaction chamber is double-walled, with the cooling water circulating in the double wall and the internal surface of the double wall is covered with a refractory material. The plasmagenous gas is introduced into the torch by pressurisation. The mixture of water and waste is introduced by a spraying probe if the mixture is liquid and an injection probe if it is gaseous. The mixing device is a venturi with a double wall cooled by water, with an upper convergent part, a lower divergent part, a neck connecting the convergent and divergent parts and air inlet orifices. The recombination device is a double-walled chamber cooled by water.

Title: Interference-free ultrasound imaging during hifu therapy, using software tools
Inventor: ZDERIC VESNA
IPC: A61B8/00
Filed: 2005-09-16
Abstract: Disclosed herein is a method for obtaining a composite interference-free ultrasound image when non-imaging ultrasound waves would otherwise interfere with ultrasound imaging. A conventional ultrasound imaging system is used to collect frames of ultrasound image data in the presence of non-imaging ultrasound waves, such as high-intensity focused ultrasound (HIFU). The frames are directed to a processor that analyzes the frames to identify portions of the frame that are interference-free. Interference-free portions of a plurality of different ultrasound image frames are combined to generate a single composite interference-free ultrasound image that is displayed to a user. In this approach, a frequency of the non-imaging ultrasound waves is offset relative to a frequency of the ultrasound imaging waves, such that the interference introduced by the non-imaging ultrasound waves appears in a different portion of the frames.
