Abstract:
Method for conditioning of an electronic microcircuit designed for the production of an electronic module which can be glued by means of a simple glue or by soldering. For this purpose the microchip has a geometric shape compatible with a recess in a card provided to accommodate it and has a means serving as a mask compatible with the card. Ultimately this mask also serves to prevent an outflow of a resin coating used to protect a chip included in this type of module. The mask is glued to a support having, on a first face, the contact area, and on a second face the mask and the chip. The mask includes a window determining the placement of the chip.
Abstract:
The invention concerns a method for making a capacitive antenna (4) by performing a gravure process on the antenna comprising a single turn (9) connected to a capacitor (10), the turn and the capacitor being printed by a gravure process with a conductive ink. The use of a dielectric ink for the gravure process also enables a dielectric thickness (16) to be obtained between two conductive electrodes (14, 17) printed by gravure process. The capacitance of the capacitor is determined on the basis of the antenna inductance, the frequency of communication and the law of resonance whereto a chip (3) connected to said antenna (4) is subjected.
Abstract:
A method ensuring continuity of management of communications sessions operated from a fourth-generation mobile terminal communicating on an IP network including at least one radio network with a plurality of base stations with which said terminal is capable of communicating, said radio network connected via access gateways to an interconnection network with communications session management application servers, the sessions of a mobile terminal being managed by one of said servers, the method including: in the event of a movement of the mobile terminal resulting in a change of access gateway, the new gateway transmits an alert message to a new management server; the new management server transmits an interrogation request to the other servers in order to recover the call context of the mobile terminal; and the new server transmits an invitation to the mobile terminal accompanied by connection parameters, such that said terminal can connect to the new server.
Abstract:
In a method for the manufacture of a printed circuit on a dielectric carrier (2), in a first step a circuit pattern (1) is applied with an electrically conductive ink and, in a second step, the circuit model is plated, the electrically conductive ink being applied by means of a method of gravure printing and the plating being done by electrolytic or chemical means.
Abstract:
A coupling antenna which includes a plurality of turns in series located on a planar support (14) formed by an insulating dielectric substrate. The antenna includes one or several sets of at least one turn (16) located on the planar support, mounted in series, at least one of the sets consisting of at least two spires (16,22) in series superposed along an axis perpendicular to the plane of the support and separated by an insulating strip (20) of dielectric ink, thereby resulting in a high inductance value. The invention also concerns the method for making such an antenna and the use of the antenna in a contactless smart card.
