Method for determining the points to be supported for an object manufactured by means of an additive manufacturing method; associated information recording medium and support structure

A method for determining a set of points to be supported for an object to be manufactured by means of an additive manufacturing method, characterised in that it comprises a step consisting of subdividing the object into successive layers, each layer corresponding to a thickness of material deposited during the manufacture of the object; and, for each layer, adding, to a set of points to be supported, points to be supported (ps) on the surface of the object that make it possible to ensure the stability of all of the sub-objects (2n), a sub-object being defined as a solid resulting from the manufacture of the i first layers (ci) of the object.. . ...

Support structure for supporting an object during the manufacture of same by means of an additive manufacturing method; method for generating such a structure

A support structure for supporting an object during the manufacture of same by means of an additive manufacturing method; method for generating such a structure. This support structure (10) for supporting an object (2) during the manufacture of same by means of an additive manufacturing method, the support structure and the object being manufactured simultaneously, consists of a plurality of horizontal and straight bridges (12), vertical pillars (14) and inclined connectors (16), a bottom end of a pillar resting on a bridge, on a base plane or on a point of a surface of the object, and a top end of a pillar carrying a connector, and a bottom end of a connector resting on the top end of a pillar and the top end of a connector corresponding to a point on the surface of the object or to a point to be supported of a bridge, each bridge being supported at least at each of the two end points of same, either by a connector or by a point of the object, and the pillars and connectors being capable of having a height of zero.. ...

Image processing device

Device comprising a memory (2) storing sound data, three-dimensional surface data, and a plurality of control data sets which represent control points defined by data of coordinates which are associated with sound data, and a processor (4) which, on the basis of first and second successive sound data, and of first three-dimensional surface data, selects the control data sets associated with the first and second sound data, and defines second three-dimensional surface data by applying a displacement to each point. The displacement of a given point is calculated as the sum of displacement vectors calculated for each control point on the basis of the sum of first and second vectors, weighted by the ratio between the result of a function with two variables exhibiting a zero limit at infinity applied to the given point and to the control point and the sum of the result of this function applied to the point on the one hand and to each of the control points on the other hand. ...

Method for manufacturing a part coated with a protective coating

A method for manufacturing a part coated with a protective coating includes: forming a protective coating across all or part of the surface of a part, wherein the part includes a refractory alloy including a niobium matrix containing metal silicide inclusions, wherein the protective coating is formed by a pack carburization method from a cement including: i. A mixture a of (nbxti1-x)3m3crsi6 and m0.6cr0.4si where m denotes fe, co or ni and x is between 0 and 1, or ii. ... Universite De Lorraine

Method and circuit for detecting an electric arc in a circuit, and switching device using such a circuit

A method and a circuit for detecting an electric arc in an electric circuit supplied with ac current during a supply period includes measuring at least one input signal (s) among a current (i) and an input voltage (u) of the electric circuit, supplying a warning signal (a1) to indicate that an electric arc occurs when the input signal (s) is constant over at least one portion of the supply period, digitally sampling the input signal (s) during the measurement thereof according to predetermined levels and, to identify that the input signal (s) is constant, determining the frequency at which each level is reached by the input signal (s) over a predetermined time window, comparing the frequency of each level with a predetermined warning threshold, and issuing the warning signal if the frequency of at least one of the levels is higher than the warning threshold.. . ...
