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: The databases and methods disclosed herein reduce costly dictionary access (writes and reads) by storing data directly in an index (e.g., storing literal values or taking advantage of Universally Unique Identifiers (UUIDs)), thereby saving time and memory. One example embodiment is a database that includes a dictionary and an index. The dictionary stores associations between keys and data. Each entry in the index includes a plurality of values corresponding to data. A value of the index includes either (i) a direct representation of corresponding data for certain data types, or (ii) a hash of the corresponding data for other data types. The hash is used in the dictionary as a key associated with the corresponding data.

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 disclosure is directed to a method and corresponding system that improves accuracy of a computer simulation of an original posture of a digital human model (DHM) relative to a target object. The method and system may obtain information associated with the original DHM posture. The obtained DHM posture information may include a position of a head of the DHM. The method and system may obtain information associated with the target object. The obtained target object information may include a size of the target object and an orientation of the target object. The method and system method may obtain a distance from the head of the DHM to the target object. In some embodiments, the system and method may generate a measure of vision (i.e., vision measure) of the DHM of the target object that the DHM is visually targeting. The system and method may generate the measure of vision based on one or more parameters which may include any of the obtained DHM posture information, the obtained target object information, and the obtained head-target (HT) distance. Based on the measure of vision, the system and method may generate a constraint of vision (i.e., vision constraint) of the DHM to the target object. Based on the vision constraint, the system and method may generate an updated DHM posture.

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.

Abstract: Modal dynamic analysis for finite element models (FEMs) that include Lagrange multipliers may generate incorrect stress and reaction forces. Computer systems and computer-implemented methods are provided for modifying the modal analysis to correctly generate stress and reaction forces. The systems and methods perform the modal analysis by employing a FEM and modeling stress and reaction forces of the FEM using Lagrange multipliers. The systems and methods calculate a correction term that comprises corrected values of the Lagrange multipliers. The methods and systems modify (and improve) the modal analysis by using the correction term to correct the Lagrange multipliers of the FEM, which enables the modal analysis to generate correct stress and reaction forces.
