Abstract

The present invention relates to a method of compressed sensing of a spectrally-sparse signal within a given spectral band, the received signal being mixed (820) over a sensing frame with a pulse train scrolling with a repetition frequency linearly modulated over time within this frame. The result of mixing is filtered (830) by means of a low-pass filtering and sampled (840) at a non-uniform rate equal to the repetition frequency, to result in complex samples representative of the received signal. The spectrum of the received signal can be estimated by weighting by means of the complex samples the spectral values of a pulse into a plurality of frequency equidistributed in the band, and by summing up these weighted values for each of these frequencies. An estimate of the received signal is thereby deduced by inverse Fourier transform. The spectral band can be scanned based on the spectrum thus estimated.

Abstract

The present invention concerns a method for programming a Bayesian neural network (BNN) in a RRAM memory. After the BNN has been trained on a dataset D, the joint posterior probability distribution of the synaptic coefficients, p(w|D) is decomposed into a mixture of multivariate mean-field Gaussian components by GMM. The weighting coefficients and the parameters of these multivariate Gaussian components are estimated by MDEM (Multi-Dimensional Expectation Maximization) with two constraints. According to the first constraint, the off-diagonal terms of the covariance matrix of each component are forced to zero. According to the second constraint, the couples of mean values and diagonal terms of the covariance matrix of each component are constrained to belong to a hardware compliance domain determined by a relationship between the conductance mean value and conductance standard deviation of a memristor programmed by a SET or RESET operation. The weighting factors and mean values of these components are then transferred to the chip implementing the BNN, and the memristors of the RRAM are programmed accordingly.

Abstract

A membrane for collecting airborne particles, the membrane taking the form of a strip composed of a matrix formed from a mixture of a polymer and of a filler that is made of an electrical conductor, a hydrophilic layer for collecting particles, on which layer is deposited said matrix so as to form at least one composite layer, the membrane including at least one region obtained via a surface treatment of the hydrophilic layer.

IPC Classes  ?

• B03C 3/64 - Use of special materials other than liquids synthetic resins

• B03C 3/16 - Plant or installations having external electricity supply wet type
• B03C 3/08 - Plant or installations having external electricity supply dry type characterised by presence of stationary flat electrodes arranged with their flat surfaces parallel to the gas stream

Abstract

A fluidic component including a fluidic circuit having at least one fluidic access through which a fluid is intended to pass, an actuator capable of expanding, a deformable membrane that can be actuated by the expansion of the actuator, sealing device for sealing off the fluidic access and including at least a body made of a meltable compound configured to adopt two states: a solid first state, a molten second state obtained under the effect of an increase in temperature, the body of meltable compound being designed to be moved in the molten state, by the expansion of the actuator, between a standby position and a distinct sealing-off position for sealing off the fluidic access.

Abstract

A fluidic component intended to be associated with a heating module and in which there is formed a fluidic circuit including a fluidic channel intended for the circulation of a fluid, the fluidic channel including at least one passage for the fluid and a widened portion forming a location produced at the periphery of the passage, the component including a fluidic valve mechanism including at least an actuating element capable of expanding, trapped by at least one body made of a meltable compound in the location.

• F16K 99/00 - Subject matter not provided for in other groups of this subclass

Abstract

Photovoltaic cell comprising: an assembly comprising a substrate, first and second passivation layers covering opposite faces of the substrate and also lateral faces of the substrate, and first and second charge-collecting layers; a first layer of TCO disposed against the first main face of the assembly and such that edges of the first main face of the assembly are not covered by the first layer of TCO; a second layer of TCO covering the whole of the second main face of the assembly; a non-reflective coating partly covering the first and/or second charge-collecting layers on the lateral faces of the substrate and not covered by the second layer of TCO, and also covering the edges of the first main face.
