Abstract: An antenna arrangement that is designed to match, or approach based on a cost function, a specification includes a list of a plurality of predefined frequencies and, possibly a list of predefined bandwidths at a matching level. The antenna arrangement is designed using a plurality of predefined elements comprising a primary conductive element defined as a main trunk and a combination of secondary conductive elements selected from trunks, branches or leaves. The primary conductive element and the secondary conductive elements are defined by design parameters that comprise a susceptance that is a function of a geometry, a form factor, a main dimension, an orientation of the secondary conductive elements relative to the primary conductive element and a position of the secondary conductive elements on the primary conductive element. The antenna arrangement may be further defined to match a predefined form factor.

Abstract: A method for producing an expanded rigid foam with sealed pores includes at least the following steps: a) a mixture is prepared containing at least: an anionic polymer suited for ionotropic gelation; a foaming agent; a source of multivalent cations, said multivalent cations not being released in the mixture a); and a solvent; b) the mixture is stirred so as to obtain a foam; c) a compound capable of releasing protons in a sufficient amount to release said multivalent cations is added to the foam such that the anionic polymer gels ionotropically; d) the foam is dried. A foam is obtained in this manner and an object (for example a package, a heat-insulating or flame-retardant material) is made from this foam.

Abstract: A method of determining a performance metric for a selection of a first user and a second user among a set of candidate users for attribution to a sub-band in a multiple access communications system based on Non-Orthogonal Multiple Access (NOMA), is provided wherein the first user (k1) and the second user (k2) are selected as the pair of candidate users corresponding to an extremum of the ratio between a first term reflecting the total throughput achievable by any pair of the candidate users assigned to the sub-band (s) under consideration, and a second term reflecting the known throughput achieved by that same pair of candidate users over a predetermined preceding period. Implementations include a method of determining a performance metric is presented for attributing users to one or more of a plurality of sub-bands in a multiple access communications system, wherein in an initial assignment phase for a specific sub-band, a first user is selected for that band on the basis of one or more criteria such as user priority. Then a second sub-band user maximizing or minimizing the performance metric.

Abstract: An optical system for detecting and tracking the eye movements of an individual. The system includes a frame, intended to be worn on the face of the individual, that includes a plurality of illumination sources. The system includes at least one contact lens, intended to be worn by an eye of the individual facing the frame, in which are encapsulated: an autonomous integrated circuit, a plurality of photoreceptors and a wireless communication transmitter. Variation in a signal (e.g., voltage or current) delivered by the photoreceptors allows not only the closure of the eyelid but also eye movements to be detected.

Abstract: The present invention relates to a method for learning class descriptors for the detection and the automatic location of objects in a video, each object belonging to a class of objects from among a set of classes, the method using: a learning base, composed from reference videos and containing annotated frames each comprising one or more labels identifying each object detected in the frames, descriptors associated with these labels and learned previously by a preprocessing neural network from the annotated frames of the learning base, an architecture of neural networks defined by parameters centralized on a plurality of parameter servers, and a plurality of computation entities working in parallel, a method in which, for each class of objects, one of the neural networks of the architecture is trained by using as input data the descriptors and the labels to define class descriptors, each computation entity using, for the computation of the class descriptors, a version of the parameters of the parameter server on which the entity depends, and returning to this parameter server the parameters updated at the end of its computation, and the parameter servers exchanging with one another the parameters of each computation entity for the training of the neural networks for each class descriptor.

Abstract: A method for locating at least one receiver within a positioning system, the system including: at least two transmitters, each transmitter emitting a signal including a carrier modulated by a code, and a receiver that is movable and configured to detect the signals, method in which: during the movement of the receiver from an estimated predefined initial position, consecutive measurements are taken of the phase of the carrier of the signal emitted by each transmitter, for various subsequent positions of the receiver, the variations in the phase of the carrier of the signals between each subsequent position of the receiver for which the phase was measured and the estimated initial position of the receiver is calculated for each transmitter, and these phase variations are used to calculate the variation in distance between the receiver and the transmitters, in order to determine the real initial position of the receiver.

Abstract: The invention relates to a mode selection method for a system for MIMO transmission on an optical fiber of multimode type. It comprises a step of measuring the transfer matrix of the transmission channel made up of a set of modes of the optical fiber (110), a step of transforming (120) the transfer matrix into a block diagonal matrix, each block being associated with a mode subset, a step of determining (130) the gain and/or the transmission capacity for each of the mode subsets, and a selection (140) of the mode subset corresponding to the highest gain and/or capacity, the MIMO transmission system then using only the modes of the subset thus selected to transmit on the optical fiber.The invention relates also to a core selection method for a system for MIMO transmission on optical fiber of multicore type.
