  • Towed low-frequency underwater detection system
    Patent number: 6901029
    Abstract: The invention relates to low-frequency underwater detection systems comprising a towed linear antenna (12, 13). It consists in producing the transducers of the transmission antenna (12) in the form of flextensional arrays of cylindrical type (20) and in forming directional transmission channels covering all of space. It makes it possible to lighten the assembly and to facilitate implementation at sea, which becomes able to be automated.

  • Power amplifier arrangement automatically matched to service conditions
    Patent number: 4131860
    Abstract: A power amplifier arrangement comprising a first control circuit for keeping the power dissipated by its transistors below or equal, for any excitation level, to a limit fixed in dependence upon the required reliability level and a second control circuit for completely exploring the zone of available linear characteristics of the transistors in dependence upon the load conditions, the ambient temperature and parameters specific to the transistors.
