The present invention relates to a method of controlling a driver assistance system which can identify a danger situation with reference to a comparison of measured data with predetermined limit values and which can output a warning signal when it has identified a danger situation of this type. Failure of one of the processing nodes is detected, followed by receipt of a request to access a first resource of the set of shared resources. The object of the invention is to complete the optical devices necessary to control the instability of lasers by specific optical devices enabling elimination of the dead zone and of population inversion gratings exiting in the amplifying medium. A first mask with an edge over the desired electrical contact location is formed on the substrate. A wideband amplification apparatus in accordance with the present invention may comprise: a high-band amplifier; a low-band amplifier; a quadrature hybrid; and a plurality of antennas. The transmitter power may be adjusted for increasing throughput or robustness of the system.
