  • Process and apparatus for producing hydrogen
    Patent number: 9090984
    Abstract: A process for producing hydrogen for use in a subsequent methanation process includes electrochemically converting water into hydrogen and oxygen. The hydrogen is depleted with electrolyte aerosols. Then, the electrolyte aerosols are separated from the depleted hydrogen in a wet electrostatic precipitator in a hydrogen atmosphere.
    Type: Grant

  • Co-channel interference detector for cellular communications systems
    Publication number: 20050107039
    Abstract: The invention offers a method of estimating the channel parameters of a co-channel interferer. Initial, rough estimates of the desired channel and of the desired data symbols are made, and a fraction of the estimated desired signal is subtracted from the received signal. The fraction depends on the uncertainty of the desired signal. The synchronisation position of the co-channel interferer is determined, which is used to reject the co-channel interference. In a pre-processing stage only rough estimates of the desired transmission channel and of the desired data symbols are needed. Consequently, a much faster convergence of the algorithm used for detecting the co-channel interference results. When the co-channel interference signal has been detected, it can be eliminated by any suitable method.
