Abstract: A process for manufacturing a blade made of composite material for a turbomachine. The blade includes an airfoil having a pressure side and a suction side which extend from a leading edge to a trailing edge of the airfoil. The blade further includes a metal sheath that extends along the leading edge of the airfoil. The process includes the steps of: placing a preform, produced by three-dimensionally weaving fibers, in a mold, the sheath being positioned on an edge of the preform intended to form the leading edge of the airfoil; and injecting polymerizable resin into the mold to impregnate the preform so as to form the airfoil after solidifying. At least one double-sided adhesive film may be inserted between the sheath and the edge of the preform prior to injection of the resin.

Abstract: A method for manufacturing a vane from a composite material with a fitted metal leading edge includes the successive draping, on a template of the leading edge of the vane to be manufactured, of a first layer of a base material and of a second layer of an adhesive material, the transfer of the first and second draped layers in the recess of a metal foil, the positioning of the foil including the first and second draped layers alongside the leading edge of a vane preform including a fiber reinforcement impregnated with a precursor of a matrix, the co-curing of the vane preform and of the first and second draped layers so as to obtain a vane made of composite material including on its leading edge a bonded metal foil.

Abstract: The invention relates to a method of inputting confidential data on a terminal including an input interface, at least one processor for running a trusted program and a display screen, the method including the following steps applied before the input: taking exclusive control of the input interface by the trusted program; displaying on the screen a trusted image known to the user of the terminal to indicate that exclusive control of the input interface has been taken by the trusted program; after control has been taken and before displaying the trusted image, selecting the trusted image as part of a reference image predetermined by the user, wherein the selected trusted image varies from one input to another. The invention also relates to a terminal for use of said method.

Abstract: A method is proposed for communicating an electronic transaction between a point of sale (1) and a transaction server (3) by way of a mobile terminal (2) being capable of connecting via an access network (R) for accessing the transaction server (3) via a main communication channel (C2), comprising the steps of: establishment of a near field communication channel (C1) with the point of sale (1), production of transaction data intended for the transaction server (3) on the basis of data transmitted by said channel (C1), verification of the availability of the main channel (C2), if said main channel (C2) is unavailable, sending of the produced transaction data along a secondary channel (C3) established with the point of sale so that the point of sale (1) can transmit the data to the access network (R).
