Abstract: An entity of the smart card (CP) type, having an application layer (AP) linked to a communication protocol layer (PR), comprises a time manager (GD) containing a timer (CD) interfacing with the protocol layer (PR) for substantially periodically constructing waiting time extension (WTX) requests transmitted to a terminal (TE) through the protocol layer as long as data are in the process of being processed in the application layer. The application layer is thus freed from any time constraint.

Abstract: A device for smoothing current and voltage transients and for preventing an electric arc being formed during a connection operation whereby a power supply battery is put into circuit with high-power electrical equipment that it is to power, and/or during the opposite, disconnection operation during which the circuit via which the battery powers the equipment is interrupted. It provides for inserting a circuit for smoothing current/voltage transients to compensate for any voltage unbalance that might appear between the two terminals between which the connection between the battery and the equipment is alternately made and broken, one of the terminals belonging to the battery and the other to the equipment.
