Abstract: The invention relates to a method for processing the surface of polymer substrates, during which the substrate is subjected to a dielectric-barrier electric discharge of the filament type in a gaseous processing mixture containing at least a carrier gas and an active gas and under a pressure substantially equal to the atmospheric pressure, characterized in that the active gas is selected from the group including a mono-unsaturated or poly-unsaturated linear or branched hydrocarbon preferably containing 2 to 10 carbon atoms, more preferably 2 to 5 carbon atoms and even more preferably 2 or 3 carbon atoms, the residual oxygen content of the processing mixture being lower than 250 ppm, preferably lower than 100 ppm, and more preferably lower than 50 ppm.

Abstract: The invention relates to a method for controlling data transmission in a communication system transmitting data in packet format between a first (142, 162) and a second (170) transceiver on at least one physical channel. To transmit data blocks between the first and the second transceiver, at least one logical connection is established, each logical connection using ARQ error correction and a related transmission window. The number of logical connections is selected on the basis of the number of data blocks per unit of time, which can be transmitted between the first and the second transceiver.

Abstract: Even with techniques increasing a basic transmission rate, i.e. a modulation method of the EDGE and usage of several basic traffic channels to form a high-speed traffic channel, the theoretical maximum data rate of a logical link, and thus of a radio bearer, is 473.8 kbits/s. That is, however, not sufficient for satisfying new requirements of up to 2 Mbits/s. The new requirements, and even higher data rates, can be achieved by having several simultaneous single carrier logical links (TBFs), and thus logical channels, for one radio bearer between a mobile station and a network. The number of supported carriers, and preferably also the maximum multicarrier allocation bandwidth, is indicated in a multicarrier class of a mobile station.

Abstract: A device for accurately positioning the vertex of a secondary mirror (5) off-centered with respect to that of a primary mirror (3) of a telescope (1). The secondary mirror (5) is connected to a support (8). The connection (9) includes two radial and crossed elongate connecting members (10) which extend on either side of the support (8) (along a first direction X--X and a second direction Y--Y) passing through the center (0) of the support, corresponding to the vertex (5A) of the secondary mirror (5). Each of the connecting members (10) is longitudinally rigid and transversely flexible. Each of the connecting members is capable of being controlled, in order to move along its longitudinal extent by an actuation device (11).
