  • Patent number: 9905332
    Abstract: The present invention relates to a multilayer conductive transparent electrode comprising: a substrate layer (1), a conductive layer (2) comprising at least one optionally substituted polythiophene conductive polymer, and the conductive layer (2) being in direct contact with the substrate layer (1) and the conductive layer (2) also comprising at least one hydrophobic adhesive polymer which has chemical compatibility with the optionally substituted polythiophene conductive polymer, such that said multilayer conductive transparent electrode has a coefficient of haze of less than or equal to 3%. The invention also relates to the process for manufacturing such a multilayer conductive transparent electrode.

  • Publication number: 20170298746
    Abstract: The present invention relates to a turbine engine guide (23) vane (25), with a height (H) extending between a vane root (26) and a vane tip (27) along a radial direction (Z), said vane (25) comprising a succession of five bulge portions along a tangential direction (Y) perpendicular to the radial direction (Z), this succession of bulge portions extending over the whole height (H) of the vane (25), and the convexity of the successive bulge portions being alternately in one direction and in the other. The vane (25) has the advantage of having an eigenfrequency for the first striped vibration mode which is different from the urging frequencies of said vane (25), during the operation of the turbine engine.

  • Patent number: 9245058
    Abstract: A method of metadata management is provided. Metadata associated with information objects is important in the management and classification of electronic information referred to as information objects. A metadata schema structure definition is defined enabling a metadata schema to be applied to the information objects to ensure consistent creation and management of hierarchical metadata across and organization and interoperability between different metadata schemas.

  • Patent number: 8869299
    Abstract: A method and system for generating trusted security labels in electronic documents is disclosed. The method comprises determining parts of the document to be cryptographically bound to the security label and hashing them; hashing the security label; specifying any necessary policies as signable signature properties; and digitally signing the collection of these items. The resulting security label is trusted, because it is digitally signed and its digital signature also covers the parts of the document to be protected, thus allowing any tampering of the security label or the covered parts of the document to be detectable. A corresponding system for generating trusted security labels is also provided.
