  • Publication number: 20240005627
    Abstract: A method of conditional neural ground planes for static-dynamic disentanglement is described. The method includes extracting, using a convolutional neural network (CNN), CNN image features from an image to form a feature tensor. The method also includes resampling unprojected 2D features of the feature tensor to form feature pillars. The method further includes aggregating the feature pillars to form an entangled neural ground plane. The method also includes decomposing the entangled neural ground plane into a static neural ground plane and a dynamic neural ground plane.

  • Patent number: 10242427
    Abstract: Geometries of the structures and objects deviate from their idealized models, while not always visible to the naked eye. Embodiments of the present invention reveal and visualize such subtle geometric deviations, which can contain useful, surprising information. In an embodiment of the present invention, a method can include fitting a model of a geometry to an input image, matting a region of the input image according to the model based on a sampling function, generating a deviation function based on the matted region, extrapolating the deviation function to an image wide warping field, and generating an output image by warping the input image according to the warping. In an embodiment of the present invention, Deviation Magnification inputs takes a still image or frame, fits parametric models to objects of interest, and generates an output image exaggerating departures from ideal geometries.

  • Patent number: 10037609
    Abstract: A method and corresponding device for identifying operational mode shapes of an object in a video stream includes extracting pixel-wise Eulerian motion signals of an object from an undercomplete representation of frames within a video stream. Pixel-wise Eulerian motion signals are downselected to produce a representative set of Eulerian motion signals of the object. Operational mode shapes of the object are identified based on the representative set. Resonant frequencies can also be identified. Embodiments enable vibrational characteristics of objects to be determined using video in near real time.

  • Patent number: 9582925
    Abstract: This processing method provides the ability to process a volume mode with an object intended to be added to or subtracted from said model. The volume model includes points arranged according to a spatial grid in a first reference system, each point being assigned an intensity value. The object has points positioned in a second reference system that is distinct from the first reference system. The method includes the calculation, for each point of the object, of an image point in the first reference system using a transfer function. The method further includes the modification of the intensity of points of the volume model by applying a correction function associated with each image point, the value of the correction function at a point of the volume model being dependent on the position of said point relative to said image point with which said correction function is associated.

  • Publication number: 20160051161
    Abstract: The invention relates to a method for estimating the brain activity, from physiological signals, in particular magnetoencephalographic or electroencephalographic surfaces, which has, in certain predetermined areas of the cortex, considered as areas of interest, an improved accuracy with respect to other areas of the gridding. It enables a more accurate estimation to be obtained in the areas of the brain intended to be subjected to a particular treatment, for example to accommodate cortical electrodes.

  • Publication number: 20160051162
    Abstract: The invention relates to a method for estimating the electrical activity of a tissue using a plurality of sensors, in particular the brain activity related to a motor task performed, imagined, or visualized by a subject, using a plurality of magnetoencephalographic or electroencephalographic sensors, when this subject is submitted to a stimulus. The estimation method is based on an MNE criterion in which the coefficients of the covariance matrix of the physiological signals acquired by the different sensors are weighted using the correlation coefficients of these signals with a signal representative of the stimulus.

  • Publication number: 20050011885
    Abstract: A hand-held microwave system for intra-oral dentistry utilizes microwave energy to cure polymer materials intra-orally so as to produce dental composites having improved physical characteristics, and also utilizes microwave energy to detect the presence of and to preferentially heat caries or cavities, thereby disinfecting and therapeutically treating the caries in a potentially non-invasive manner. The intra-oral polymerization process can be accomplished with less overall energy and with composite-matrices that maximally absorb the microwave energy so as to reduce heating of adjacent tissue. The antenna of a hand-held version of the intra-oral microwave system is also advantageously designed to detect the presence of and to preferentially heat caries or cavities, thereby disinfecting and therapeutically treating the caries in a potentially non-invasive manner. A method and product by process for the system are also disclosed.

  • Patent number: 6737619
    Abstract: A microwave polymerization system for dentistry utilizes specifically controlled microwave energy to cure polymer materials so as to produce dental prosthetics, such as dentures, bridges and crowns, that are made in an extra-oral setting such as a dental laboratory or dental office, and to create dental composites for fillings and veneers that are used in an intra-oral setting directly in the patient's mouth. Unlike the microwave energy delivered by commercial microwave ovens, the system utilizes metered and controlled microwave energy that is preferably continuous and voltage controlled, and regulates the application of this microwave energy by use of various feedback and control mechanisms. The metered and controlled microwave energy enables a higher degree of conversion of monomers into polymer chains in the polymerization process, thereby enhancing the physical and biocompatibility characteristics of both dental prosthetics and dental composites made from polymers.

  • Patent number: 6237396
    Abstract: Integrated analysis process and device for characterization of hydrocarbons in a petroleum product, in distillation fractions, by simulated distillation. The hydrocarbons of a petroleum sample are characterized without fractional distillation by coupling gas chromatography (GC) with liquid chromatography (LC) techniques. GC simulated distillation (SD) is carried out. The separation column is preceded by a precolumn of the same nature but shorter. At the outlet of the main column, retention means (CT, AC) allow to collect and to store one or more light fractions that are sent each to a GC analytical column (6) allowing detailed analysis of the hydrocarbons, and one or more middle fractions. The remaining heavy fraction is collected at the precolumn outlet. The middle and heavy fractions are characterized by a combined LC-GC chromatography unit. Several interfaces allowing GC-GC-LC-GC coupling are described.

  • Patent number: 6093862
    Abstract: A process for slowing the growth and/or agglomeration of hydrates in a fluid comprising water and gases by adding at least one essentially water-soluble polyoxyalkylene glycol macromer or at least one essentially water-soluble polymer containing a single macromer or a plurality of different macromer units of polyoxyalkylene glycol or a mixture of essentially water-soluble macromers and/or polymacromers. It is also possible to both retard the formation of hydrates and to substantially slow their growth and limit their agglomeration during crystallization by combining polyoxyalkylene glycol macromer type structures with kinetic additive type structures which are known to inhibit hydrate formation.

    Abstract: The inhibiting or retarding hydrate formation, growth and/or agglomeration in a fluid comprising water and gases, is accomplished by addition of at least one hydrosoluble homopolymer or copolymer derived from at least one nitrogen-containing monomer selected from cationic monomers, for example those containing at least one quaternary ammonium moiety, amphoteric monomers, for example those containing at least one quaternary ammonium moiety and at least one carboxylate or sulphonate moiety, and various neutral monomers, said hydrosoluble homopolymer or copolymer being neutral or anionic, or consisting of a polyampholyte. The homopolymer, copolymer or mixture of polymers optionally mixed with an alcohol is generally incorporated into the fluid to be treated at a concentration of 0.05% to 5% by weight with respect to the quantity of water in the medium.
