Abstract: The invention concerns an electrochemical cell with emission controlled by electrodeposition under the action of a control voltage. The cell comprises the following flexible elements, superimposed and respectively in intimate contact: a first electrode (11) intended to be connected to a first potential of the control voltage, a first porous layer (12), formed of a mixture of PVDF-HFP, PEO and an activated carbon powder, a porous separator (13), formed of a mixture of PVDF-HFP and PEO, a second electrode (14) formed of a grid and connected to a second potential of the control voltage, a second porous layer (15), formed of a mixture of PVDF-HFP, PEO and carbon powder, an aqueous electrolytic solution containing a copper salt being contained in the first flexible layer (12), in the separator (13) and in the second flexible layer (15).

Abstract: The invention concerns an electrochemical cell in thin films and aqueous electrolyte, with an emissivity that varies as a function of an applied control voltage.

Abstract: The system for stretch-forming composite material bands (3) includes, in addition to an unrolling head (20), an original assembly composed of a light source (4) for heating the band (3) and hardening the composite and a pair of rollers (6a and 6b) applying the desired pressure to assemble the band to a laminated composite (2) already deposited or applying it to the support (1). As the application of heat is concentrated at a distance from the rollers (6a and 6b) and with a perpendicular incidence, the rollers can be conveniently made of an elastic material, which enables them to adapt to the transverse curvature of the support equipment (1) and to apply a uniform pressure.

Abstract: A method and apparatus for testing integrated circuits by subjecting the circuits to an electromagnetic disturbance. A probe is provided, equipped with a horn cover designed to be applied to a printed circuit on which an integrated circuit is mounted. Within this horn cover, a core shield channels the electrical field that is deployed in a zone in which connections from the integrated circuit to the printed circuit that it carries are situated. The effectiveness of the electromagnetic interference injected in the integrated circuit is increased to the point that a true measurement of the resistance of this integrated circuit to the electromagnetic interferences may be carried out.
