The present invention relates to a device 1 for allowing the use in a aircraft A of at least one radio communication apparatus (R), such as mobile telephones. According to the invention, the radio communication apparatus (R) includes a first connection switch (MC1) between an information processing unit (2) and a transmit unit (3), and a connection switch (MC2) between the processing unit (2) and a receiving unit (5), and the device (1) includes a transmitter (8) transmitting waves (OE) out of the aircraft (A), a receiver (10) detecting waves outside the aircraft (A), and paths L1 and L2 respectively linked to the transmitter (8) and to the first connection switch (MC1) and to the receiver (10) and to the second connection switch (MC2).

Device for allowing the use in an aircraft of radio communication means

The invention relates to a process and system for obtaining the maximum power from an assembly of photovoltaic cells. According to the invention, the D.C. power furnished by said assembly is converted, with the aid of a converter controlled by a modulated signal, into an A.C. power, and the value of the rate of modulation corresponding constantly to the maximum power, is determined for example with the aid of a microprocessor. The invention is applicable to the generation of solar energy with coupling on the network of a converter.
