Abstract: A circuit and method are provided for recuperating energy and decreasing driver power consumption in a switching converter. An inductor is directly connected between a gate driver and a gate electrode of a switch. A first burst pulse signal is generated, wherein energy from a power source is stored in the inductor and transferred to a parasitic capacitance of the switch. A driving pulse signal is subsequently generated to the gate electrode of the switch, wherein the gate voltage is equal to the supply voltage and no balancing current flows through the inductor. After the driving pulse signal is terminated a second burst pulse signal is generated, wherein energy is accumulated in the inductive element and returned to the power source. The energy provided from the power source during the first burst pulse signal is equal to the energy returned to the power source during the second burst pulse signal.

Abstract: A method of configuring a ring-back tone server associated with a machine capable of communicating via a telecommunication network, comprising: reception by said ring-back tone server, from said machine, of an information signal including an identifier representative of a state of said machine at the moment said information signal was emitted, configuring the ring-back tone server in such a way that a piece of equipment requesting the establishment of a communication link with said machine via said network receives in return in a ring-back tone a sound signal representative of the state indicated by means of said information signal.

Abstract: A packet transmission method, in which first packets are sent by source stations (5, 6, 7) to target stations (8, 9), the source and target stations being connected via a packet mode data network (1), in which first packets (P1, P2, P3), chosen according to at least the size and the target station of each first packet from a set of first packets sent by source stations, are aggregated to form respective second packets (Pu) of the same protocol level as the first packets; when a second packet satisfies a determined transmission criterion, the second packet is sent to an address determined as a function of the target stations intended to receive first packets aggregated in the said second packet.
