Abstract: A method of manufacturing an impregnated fibrous material including a fibrous material made of continuous fibers and at least one thermoplastic polymer matrix, the method including pre-impregnating the fibrous material while it is in the form of a roving or several parallel rovings with the thermoplastic material and heating the thermoplastic matrix for melting, or maintaining in the molten state, the thermoplastic polymer after pre-impregnation, the at least one heating step being carried out by means of at least one heat-conducting spreading part (E) and at least one heating system, with the exception of a heated calendar, the roving or the rovings being in contact with part or all of the surface of the at least one spreading part (E) and partially or wholly passing over the surface of the at least one spreading part (E) at the level of the heating system.

Abstract: Procedural model digital content editing techniques are described that overcome the limitations of conventional techniques to make procedural models available for interaction by a wide range of users without requiring specialized knowledge and do so without “breaking” the underlying model. In the techniques described herein, an inverse procedural model system receives a user input that specifies an edit to digital content generated by a procedural model. Input parameters from these candidate input parameters are selected by the system which cause the digital content generated by the procedural model to incorporate the edit.

Abstract: Certain aspects and features of this disclosure relate to modeling shapes using differentiable, signed distance functions. 3D modeling software can edit a 3D model represented using the differentiable, signed distance functions while displaying the model in a manner that is computing resource efficient and fast. Further, such 3D modeling software can automatically create such an editable 3D model from a reference representation that can be obtained in various ways and stored in a variety of formats. For example, a real-world object can be scanned using LiDAR and a reference representation can be produced from the LiDAR data. Candidate procedural models from a library of curated procedural models are optimized to obtain the best procedural model for editing. A selected procedural model provides an editable, reconstructed shape based on the reference representation of the object.

Abstract: A method for determining fluorescence values {?ispe}i?{1, 2, . . . , I} of a set of I fluorescent microparticles {?Pi}i?{1, 2, . . . , I} of a multiplexed analysis, the microparticles being in a monolayer arrangement, includes acquiring a digital fluorescence image of the set of fluorescent microparticles {?Pi}i?{1, 2, . . . , I}; and computing, for each fluorescent microparticle ?Pi in the set of fluorescent microparticles {?Pi}i?{1, 2, . . . , I}, a fluorescence value ?imeas based only on pixels of the acquired image corresponding to said fluorescent microparticle ?Pi. The method includes computing the fluorescence value ?ispe of the fluorescent microparticle ?Pi by correcting its first fluorescence ?imeas by a cross-talk fluorescence contribution ?icross in the first fluorescence ?imeas from other fluorescent microparticles {?Pj}j?i in the set of fluorescent microparticles {?Pi}i?{1, 2, . . . , I}.

Abstract: The invention relates to a laser diode structure, specifically for use in gas detection, with a hermetically sealed housing with electrical connections having a bottom and a window. A laser diode chip and a temperature control system for the laser diode chip are provided in the housing. A thermo element in the form of a Peltier element forms the temperature control system, and is connected via a lower flat surface to the bottom of the housing and via an upper flat surface to the laser diode chip, with a temperature-controlled beam shaping element as collimator provided between the laser diode chip and the window of the housing that acts on a laser beam emerging from a laser aperture of the laser diode chip before it passes through the window. The beam shaping element is in contact with the laser diode chip and is preferably connected via a boundary surface to the laser aperture with surface-to-surface contact or adhesively, or is made in one piece together with the laser aperture.

Abstract: A laser diode structure for generating a collimated or divergent laser beam, preferably for application in gas detection, with a laser diode arranged in a closed housing, with the housing comprising a housing bottom, an exit window, electrical connections, a temperature control device for the laser diode, and an optical element for influencing the laser beam. The temperature control device carrying the laser diode is arranged on the housing bottom and the optical element is positioned at a distance from the laser diode. The invention proposes an electrically controllable power device for the cyclic alteration of the position and/or alignment of the optical element in relation to the laser diode so that the optical path length for the laser beam in the housing changes periodically.
