Abstract: The communications interface enables a processor unit to dialog with an IC card having an elementary time unit (ETU) for transmitting one bit that is equal to (K/Fs). The IC card includes a microprocessor, a clock pin for application of an external clock signal enabling the microprocessor of the IC card to be clocked, and an I/O pin. The microprocessor receives external data or transmits data via the I/O pin. The communications interface includes a serial communications line for interchanging data with the IC card via the I/O pin. The communications interface also includes a transmitting module, which is written-addressable by the processor unit and includes a serialization module for serializing and transmitting, over the serial communications line, data received from the processor unit. The communications interface also includes a receiving module, which is read-addressable by the processor unit and includes a serialization module for serializing data received over the serial communications line.

Abstract: The present invention relates to ionically conductive polymeric materials, to their preparation and to their use as a solid electrolyte. The materials comprise a solid solution of one or more salts in a polymer and are characterized in that the transport and the mobility of a metal cation M.sup.n+ which has the valency n, 1.ltoreq.n.ltoreq.5, are provided by at least one complex anion, corresponding to the general formula [MZ.sub.n Y.sub.p ].sup.p- formed between an anionic ligand Z.sup.-, an anionic ligand Y.sup.- and the cation M.sup.n+, with 1.ltoreq.p.ltoreq.3. Application to the formation of electrochemical generators and of electrochemical systems which make it possible to affect the transmission of light.
