Abstract: The invention relates to a head (2) for a tank (1) used to store pressurised gas, comprising, in an integrated manner: at least two components (131, 132) for treating, distributing and/or shutting off the gas; an upstream connector (20) suitable for being removably attached in a boss (4) of the tank (1); and downstream outlet pipes (211, 212) suitable for connecting the head (2) to any system using said gas by means of the aforementioned components (131, 132). According to the invention, each component (131, 132) comprises at least two sealing devices (141, 142) defining an intermediate space therebetween, and at least one pipe (12), called tapping pipe, connects each of the intermediate spaces and a common space (8) into which ail the tapping pipes (12) emerge, with an orifice (15) providing a connection between the common space (8) and a gas-detection device (16).

Abstract: A method is provided for managing the spatial reuse of slots in a mobile network comprising several nodes Ni, said network comprising one or more Potentially Disruptive Nodes (PDN), said nodes Ni and PDN comprising a local table, a global table, and a summary of the global table comprising the interleaving of two sub-cycles: a first sub-cycle, the normal S-cycle, where S-SLOTs are all assigned statically and where each node has one or only one S-SLOT allocation, a second sub-cycle, the improved S-cycle, where each node has one S-SLOT assigned statically, and where for all nodes except PDN nodes, one or more additional S-SLOTs is assigned dynamically when topology makes it possible, dynamic S-SLOT allocation being equitably shared in a 2-hop neighborhood, and determined by performing S-SLOT spatial reuse.

Abstract: A method for managing node communications in a mobile ad-hoc network is provided where at least a node in the said network performs the following steps: identifying if it is a Potentially Disruptive Node (PDN) or a non-PDN node, a PDN node being a node that has a number of connected 1-hop neighbor nodes greater than a predetermined value K; when the node is identified as a PDN node, selecting a subset of its 1-hop neighbor nodes, the selected nodes being the only 1-hop neighbor nodes that are allowed to communicate directly with the PDN node, the selected nodes being called Bridge Nodes (BN), non-BN nodes being called Regular Nodes (RN), the said RN nodes being able to communicate with PDN nodes via the selected BN nodes.
