Abstract: Reflective optics for transporting, transforming or correcting a light beam in particular of the laser type, including a mirror receiving the light beam, a primary cooling circuit formed by an intermediate chamber of thermally conductive fluid arranged against the mirror at the rear thereof, and a secondary cooling circuit formed by a thermal heat sink arranged against the intermediate chamber of thermally conductive fluid, the heat sink being either in the form of a cold mass cooled by convection or conduction, or in the form of a plate made from a material with good thermal conductivity, the heat sink having a size and a shape equivalent to those of the reflective optics.

Abstract: The invention relates to a pretreatment process for a brazing composition that comprises metallic particles with a granulometry in the order of the micrometer or nanometer, one or several binders and one or several solvents, said process comprising: a desolvation step of the brazing composition, so as to obtain a desolvated brazing composition, then a compacting step of the desolvated brazing composition so as to obtain a preform of metallic particles, said preform being able to be used for the sintering of an electronic, photonic, thermal or mechanical component onto a substrate, the brazing composition being represented either by a brazing paste, or by a suspension of metallic or metallic oxalate grains in suspension in a solvent.

Abstract: A medical imaging apparatus and a device to detect the position of a moving part of the body of a patient. The detection device includes a management module including electronic and electric components including a differential pressure sensor linked to a measuring device that generates a differential pressure representative of the respiration flow rate of the patient, the management module being organized so as to perform at least: one acquisition and processing of the data produced by the differential pressure sensor for the generation of data representative of the respiratory volume and for the generation of an outgoing digital synchronization signal; the reception of an incoming digital synchronization signal; the generation of an outgoing digital signal of data representative of the respiratory volume in line with one of the two synchronization signals.

Abstract: The invention relates to a measuring device to generate a differential pressure representative of the flow rate of gaseous flow for medical imaging, including: a central body provided with longitudinal channels communicating with an inlet and outlet for the gaseous flow, a casing surrounding the central body, and seals delimiting a first space for measuring an upstream pressure and a second space for measuring a downstream pressure, each of which communicates with at least one of the longitudinal channels, and a third space for warming the central body. The invention also relates to a device to detect the position of a moving area, analysed by medical imaging, of the body of a patient, as well as medical imaging apparatus incorporating such a detection device.

Abstract: A correction and focusing device for a beam, through the deformation of a mirror, wherein it incorporates a frame supporting the mirror, at least one curve generator applying at least one torque to at least one extremity of the mirror, and correction actuators spaced along the mirror so as to apply stresses to the different zones of the mirror.
