  • Patent number: 11919808
    Abstract: A method for manufacturing cement may include: supplying at least one etching effluent of a substrate based on silicon including a silicate of an alkali metal, M, having formula SiO2:M2O, and having a molar ratio SiO2/M2O greater than or equal to 0.8; supplying an aluminosilicate raw material, and mixing the aluminosilicate raw material with the etching effluent having a molar ratio SiO2/M2O greater than or equal to 0.8. The silicate solution of alkali metal may be recovered with an existing silicon industrial process, implementing a silicon etching. The environmental impact of the method of manufacturing cement may therefore be reduced.

  • Patent number: 11919083
    Abstract: A method for interconnecting components of an electronic system includes depositing a sintering solution onto a first component to form an interconnection layer, the sintering solution having metal nanoparticles dispersed in a solvent, and a stabilizing agent adsorbed onto the nanoparticles. The nanoparticles have for more than 95.0% of their mass a metal selected from silver, gold, copper and alloys thereof and have a polyhedral shape with an aspect ratio of more than 0.8. The method also includes eliminating, at least partially, solvent from the layer to form an agglomerate in which the stabilizing agent binds nanoparticles together and maintains at least a portion of the nanoparticles at a distance from each other; debinding and sintering the layer by bringing the agglomerate into contact with a destabilizing agent to aggregate and coalesce the nanoparticles and depositing a second component in contact with the layer before or during debinding or sintering.

  • Patent number: 11923576
    Abstract: Fuel cell batteries are provided, and in particular hydrogen fuel cell batteries composed of at least one stack of cells. The battery is divided into at least two groups of cells able to be supplied with hydrogen separately. In a first phase, only the first group of cells and not the second is supplied; unconsumed hydrogen may however flow between the two groups via at least one evacuation manifold connected to the cells of the two groups. In a second phase, the supply to the two groups is reversed, unconsumed hydrogen still being able to flow between the two groups via the evacuation manifold. In a third phase, after a series of alternations of the two first phases, the two groups are first simultaneously supplied, then a purge valve of the evacuation manifold is opened then closed.

  • Patent number: 11917046
    Abstract: The present invention relates to a method for synchronising a node in a deterministic mesh network, in particular a network of sensors using a channel hopping (TSCH) transmission medium access mode. Each node measures the successive synchronisation offsets of its local clock in relation to those of neighbour nodes with which it enters into communication, the measurement being carried out by detecting a reception event of a packet transmitted by the neighbour node or an acknowledgement of a packet transmitted by said node to the neighbour node. The node estimates from these synchronisation offsets, a synchronisation offset for the timeslot and corrects its local clock by a fraction of the synchronisation offset thus estimated. Said fraction may be determined by means of multi-agent reinforcement learning (MARL), each agent being associated with a node of the network.
