The invention relates to the design of a 3D capacitor comprising inter-digitated nanowires. The nanowires are electrodeposited in a conventional membrane. The electrodeposition is carried out using a mask that is also a membrane. The superposition of the two membranes allows nanowires to be grown in each channel formed by linking a pore of the object membrane with a pore of the mask membrane. By chance, only some of the pores of the object membrane form channels with pores of the mask membrane. The electrodeposition is stopped before the nanowires fill the object membrane. The mask is then removed. A gold film is then sputtered onto the face, which was free, of the object membrane. A second electrodeposition is carried out in the pores that were blocked beforehand by the mask. Once again, deposition is stopped before the nanowires fill the pores. Lastly, a gold film is sputtered onto the side that made contact with the mask.

A method for characterizing a dynamic occupancy of a space by two opposing teams of a game, including a movable sporting accessory, such as a ball, a puck or a shuttlecock, each team including at least one player. The method makes it possible to determine, for each player and for all or some of the points on the pitch, a value representative of how far in advance the player is to the point of the pitch, the representative value being computed by a comparison between the duration of movement of the player to the point of the pitch and the duration of movement of a distinct player and/or of the sporting accessory to the same point. A system is also provided for characterizing a dynamic occupancy of a space by two opposing teams of a game, implementing the method.

A computer-implemented method for training a deep-learning generative model configured to output 3D modeled objects each representing a mechanical part or an assembly of mechanical parts. The method comprises obtaining a dataset of 3D modeled objects and training the deep-learning generative model based on the dataset. The training includes minimization of a loss. The loss includes a term that penalizes, for each output respective 3D modeled object, one or more functional scores of the respective 3D modeled object. Each functional score measures an extent of non-respect of a respective functional descriptor among one or more functional descriptors, by the mechanical part or the assembly of mechanical parts. This forms an improved solution with respect to outputting 3D modeled objects each representing a mechanical part or an assembly of mechanical parts.

The goal of the current invention is a polarimetric microscope working in reflection for the measurement of the refractive index of materials, including both isotropic and uniaxial anisotropic materials, in liquid and solid phases, and in the latter case, measuring both planar and non-planar surfaces. The polarimetric microscope allows measuring the refractive index of optical elements already integrated into devices (as lenses integrated into cameras), and thus, elements that can not be measured in transmission. The associated optical method is also subject of the current invention. It permits, thorough a comparison of experimental data with a theoretical optical model developed by the inventors, the characterization of the optical characteristics of those elements, as their refractive index, the ordinary and extraordinary refractive indices of uniaxial anisotropic materials, or its optical axis orientation. For the accurate and precise measure of the refraction index, the microscope includes confocal measurements.
