Abstract: A method for teletransmitting to a processing site a captured video stream of a remote intervention scene comprises modifying the captured video stream so as to erase defined zones, then transmitting this stream thus modified to the processing site. The teletransmitting method is employed to remotely assist a field operator with an intervention on a site that is sensitive in terms of confidentiality. The video stream may be captured directly by the operator or from a drone, for example.

Abstract: An embodiment of the invention involves increasing the penalty stiffness within a finite element simulation increment, which is more accurate because it avoids following a solution path with significant non-physical penetrations. An embodiment of the present invention begins by determining a first value of a parameter used by a finite element simulation of a load increment. Next, a first solution of the finite element simulation is determined by performing Newton iterations using the first value of the parameter until a first convergence check is satisfied. Then, a second value the parameter is determined wherein the second value of the parameter is unequal to the first value of the parameter. Finally, a second solution of the finite element simulation is determined by continuing the Newton iterations using the second value of the parameter until a second convergence check is satisfied, the first convergence check being different than the second convergence check.

Abstract: An embodiment may include, for a real world moving object moving along a real world path, modeling trajectory of the moving object along a polygon. The polygon may have a plurality of line segments and vertices and may represent the real world path for the moving object. A turn radius may be calculated at each vertex of the polygon. For a given vertex, the calculated turn radius may be associated with line segments of the polygon that originate from the given vertex. Using the calculated turn radii, a single-dimensional model may be formed of the real world path, where a respective calculated turn radius of the given vertex may serve as a measure of curvature of that portion of the real world path represented by the given vertex. The calculated turn radius of the respective given vertex may be defined by lane width of the real world path.

Abstract: In the proposed approach cluster elements (bins) are made available as a keypad in the form of a cluster map. The user directly selects the cluster element (bin) with a mouse, touch or actual keypad. For each of the associated attributes, a cluster map is available that orders the attributes from high-to-low by color or shade intensity. When a cluster element is selected in one cluster map, that same cluster element is also highlighted in other cluster maps. For each of the cluster maps, a value axis is available which shows the value of the parameter for the selected cluster element. In the case of numerical values, the high/low attribute pattern across the cluster maps is easily visible. The selected data objects in the cluster map are displayed in a separate widget.

Abstract: The present invention provides a computer implemented method for editing a product. The product comprises three-dimensional modeled objects. The method comprises the step of displaying a three-dimensional representation of a hierarchy of the three-dimensional modeled objects. The three-dimensional modeled objects are displayed three-dimensionally in the representation. The method further comprises the step of selecting at least one of the displayed three-dimensional modeled objects. The method further comprises the step of performing an action on the selected object. The hierarchy is edited upon the performing of the action.

Abstract: A computer-implemented method for partitioning a computer-aided design 3D model of a mechanical part. The method including obtaining a volumetric B-Rep of the CAD 3D model, detecting one or more ribbons of the volumetric B-Rep, ranking the one or more detected ribbons based on one or more geometrical criteria that are associated with each of the one or more detected ribbons, and selecting successively following the ranking each of the ranked one or more detected ribbons. The method further comprises, for each selected ribbons partitioning the volumetric B-Rep of CAD 3D model using a splitting method associated with the geometrical criteria of the selected ribbon, thereby obtaining two or more partitions, and for each obtained partition, determining whether the partition represents a sweepable volume.

Abstract: A computer-implemented method and system determine an initial or starting position of a manikin for use in simulation. The method automatically analyzes environment data to determine a highest ranking type of data from among the environment data. In response, a guiding vector and a sweep mode are determined based upon the determined highest ranking type of data. The determined guiding vector and sweep mode are used to automatically analyze free space between a manikin and a target object in a simulated real-world environment to determine an initial position for and pre-position of the manikin in a simulation of the real-world environment.

Abstract: Embodiments simulate electrostatic painting on a real-world object. An embodiment begins by receiving an indication of paint deposition rate and an indication of maximum paint accumulation for a given real-world robotically controlled electrostatic paint gun. Next, paint deposition of the given real-world robotically controlled electrostatic paint gun in a virtual environment is represented which includes, for a subject time period, computing total paint accumulation (electrostatic and direct) on a given surface element of a model representing the real-world object. In turn, a parameter file is generated that includes parameters accounting for the determined total paint accumulation for the given surface element, where the generated parameter file enables precision operation of the given real-world robotically controlled electrostatic paint gun to paint the real-world object.
