  • Patent number: 10644223
    Abstract: A piezoelectric hydrophone with perforations and an array comprising a plurality of hydrophones comprises a stack of layers that are bonded to one another, the layers comprising at least one piezoelectric layer and a plurality of layers referred to as rigid layers, at least two of which are electrode layers, the rigid layers exhibiting a stiffness perpendicularly to the direction of stacking, which stiffness is higher than the stiffness of the piezoelectric layer perpendicularly to the direction of stacking. At least one piezoelectric layer comprises a central zone comprising a set of perforations that pass through the piezoelectric layer solely along the direction of stacking, each perforation being closed tight by closure elements comprising portions of two of the rigid layers, the two rigid layers extending over the entirety of the surface of the central zone.

  • Patent number: 10324769
    Abstract: To control the processing of a multimedia object (OM) by a software application (AppL) implemented within a communication device (DC), a control application (AC) implemented in the communication device intercepts a call from the software application to an execution environment (EE) to carry out a basic operation on the multimedia object, the multimedia object being divided into segments each associated with control data (DonC) comprising at least some data from among semantic data (DonSm), sensitivity data (DonSb), and functionality data (DonF), associates transformation parameters (ParT) comprising at least one functionality parameter (ParF) and at least one semantic parameter (ParSm) and one sensitivity parameter (ParSb) with the call, depending upon the context in which the call is executed.

  • Publication number: 20180343188
    Abstract: A method includes a) in the source domain sending a trusted path computation request to each of the trusted neighboring domains; b) in each trusted downwards neighboring domain, determining whether this latter is the destination domain or not; and if it is not the destination domain, seeking every next trusted downwards neighboring domain and, seeking at least one trusted path segment that can reach a found next trusted downwards neighboring domain, and then forwarding the trusted path computation request to the found next trusted downwards neighboring domain; and re-iterate all the step b. If it is the destination domain, seeking within this destination domain every trusted path segment that can reach the second machine, and, if there is at least one such segment, sending a positive response message; c) when all the trusted downwards neighboring domains have been processed, re-iterate step b for each next trusted downwards neighboring domain.

  • Publication number: 20130190510
    Abstract: Amines and boranes are the archetypical Lewis bases and acids, respectively. The former can readily undergo one-electron oxidation to give radical cations, whereas the latter are easily reduced to afford radical anions. The present invention provides the synthesis of neutral tricoordinate boron derivatives, which act as a Lewis base, and undergoes one-electron oxidation into the corresponding radical cation. The present invention also provides borylene (H—B:) and borinylium (H—B+.) complexes stabilized by two cyclic (alkyl)(amino)carbenes. Ab initio calculations show that the HOMO [Highest Occupied Molecular Orbital] of the borane as well as the SOMO [Singly Occupied Molecular Orbital] of the radical cation are essentially a pair and a single electron in the p(?)-orbital of boron, respectively.
