Abstract: A sample may be generated for each point of a plurality of point clouds that represent a scene. A visibility ray may be created between each point of the plurality of point clouds and the one or more sources that generated the point. One or more sample, if any, that intersect a visibility ray may be identified. Each point corresponding to an intersecting sample may be determined to represent or likely represent an unwanted object if the visibility ray is from a different source that did not generate the point and the point is not coherent with any points generated by the different source. A visibility score for each point determined to represent or likely represent an unwanted object may be adjusted. A model may be generated, wherein the model does not include the unwanted object in the scene but includes the permanent object with see-through characteristics in the scene.

Abstract: In various example embodiments, a variational technique is provided for texturing a polygon mesh based on source images of a scene. The technique combines information from multiple source images to generate a texture map with patches that are the most similar to corresponding patches of the source images. The texture map may be the direct result of an optimization that jointly searches for the texture map and patch correspondence, which is initially unknown. The optimization may use a variational formulation that scores every possible texture map using an energy function that includes a matching term that quantifies how similar patches of the texture map are to the corresponding patches of the source images, and a regularization term that quantifies how complex the patch correspondence is.

Abstract: In an example embodiment, techniques are provided for locking a region of fully-connected large-scale multi-dimensional spatial data (e.g., a large-scale 3-D mesh) defined by a bounding box. A region is associated with a lock state (e.g., exclusive or sharable). Clients may access the fully-connected large-scale multi-dimensional spatial data based on a comparison of the bounding box of the requested spatial data to the bounding boxes of other client's locks and their lock state.

Abstract: In an example embodiment, techniques are provided for concurrently editing fully-connected large-scale multi-dimensional spatial data (e.g., a large-scale 3-D mesh) by ensuring that edits performed by multiple clients are non-conflicting edits that are “trivially” mergeable (e.g. mergeable simply via cut-and-paste operations). Conflicting edits may be prevented by locks (e.g., region-based locks). Non-conflicting edits that require “non-trivial” merging may be prevented through the use of marked read-only boundaries.

Abstract: An electronics structure includes at least one barrier impermeable to fine particles, interposed between at least one Electrical and/or Electronics (“E & E”) system and the frame of the structure. The barrier delimits, with the frame and the E & E system, a first area isolated from the outside of the electronics structure. The structure makes it possible to isolate sensitive electrical and electronic components from fine particles such as dust dispersed outside the electronics structure.

Abstract: A cold plate for cooling heat-generating components, includes two plates extending parallel to each other. A core is sandwiched between the two plates to form a sandwich structure, the core including a set of passages for passing a cooling fluid from a first edge to an opposite second edge of the sandwich structure. First and second fluid-tight joining members are disposed respectively on the first and second opposite edges of the sandwich structure, the first fluid-tight joining member including at least one inlet connector and the second fluid-tight joining member including at least one outlet connector for the passage of the cooling fluid. A method for use of the cold plate in particular as a structural part of an avionics equipment item is also provided.

Abstract: The invention concerns a method and devices for analyzing the feasibility of a computer system composed of subsystems, each having functions. After having determined the functional architecture of the computer system comprising at least one subsystem and at least one function, the characteristics of the functions implemented are imported from a database. The user determines the number of subsystems and the number of connectors per subsystem. He then distributes the functions to the subsystems and enters the characteristics of the connectors and the characteristics of the subsystems. The computer system is analyzed in light of the information provided by the user and the characteristics of the functions implemented in order to determine the feasibility of the computer system.
