  • Publication number: 20150090524
    Abstract: The present disclosure is related to a method for producing a cellular panel which includes a cellular structure sandwiched between first and second stiff skins. The method includes the following steps: preparing at least two blocks of cellular material; disposing the two blocks on a base ply of dry fabric, while maintaining a space between the two blocks; folding the base ply around the two blocks so as to envelop the two blocks; filling in the space with a reinforcing ply; covering the base ply with a covering ply, on a side where the reinforcing ply has been introduced; injecting resin to an assembly obtained in the previous step; and curing the assembly.

  • Patent number: 7058368
    Abstract: A method and apparatus for noise cancellation in communications systems. The method is applicable in situations where an interfering signal or noise must be cancelled within a specified bandwidth. A sample of the interfering signal is used to synthesize a cancellation signal which is of equal amplitude but opposite phase to the original interference signal. Introduction of the cancellation signal into the interference signal path results in substantially complete suppression of the interference signal through vector subtraction of the superposed signal fields. Adaptive cancellation is also provided in that the frequency and bandwidth of the cancellation signal can be controlled. The adaptive nature of the cancellation loop also tracks out imbalances between the interference and cancellation signals caused by temperature variation and component tolerances. The adaptive nature of the cancellation system also allows the system to lock onto and track an interfering signal.
