  • Electrode arrangement for generating a non-thermal plasma
    Patent number: 9889218
    Abstract: The invention relates to an electrode arrangement (1) for generating a non-thermal plasma, comprising: a layer-shaped first electrode (2) made of an electrically conductive material, a layer-shaped second electrode (4) made of an electrically conductive material, wherein the second electrode (4) is electrically insulated from the first electrode (2), and a dielectric barrier (3) being arranged between the first electrode (2) and the second electrode (4), so that the non-thermal plasma is generated by a dielectric barrier discharge. The inventive electrode arrangement is characterized in that at least one of the first electrode (2) and the second electrode (4) comprises several perforations which are distributed over the electrode.

  • Plasma source
    Patent number: 8926920
    Abstract: The invention relates to a plasma source (1) comprising: a conduit (3, 4) carrying a gas flow and an ionization chamber (10) in which a plasma is generated, wherein the ionization chamber (10) is connected to the conduit (3, 4), so that the gas flow in the conduit (3, 4) carries away gas particles out of the ionization chamber (10) thereby reducing the pressure in the ionization chamber (10).

  • Method and means of spatial filtering
    Patent number: 5822466
    Abstract: The invention relates to a method of spatial filtering a point distribution representing a structure buried in noise and each of the points of which are defined by n coordinate values of an n-dimensional space, wherein for each point the function representing the number of the points in an area around the point concerned as a function of a dimension of the area is established, and a scaling coefficient equal to the exponent (a) of a simple power function is determined which approximates as near as possible the function determined in step a) in a certain area having the dimension (d), furthermore the scaling coefficients of the points of a n-dimensional stochastic point distribution of a type equivalent to the point distribution to be filtered are determined, the difference between the scaling coefficients of the point distribution to be filtered and the scaling coefficients of the stochastic point distribution are determined, and the points, the scaling coefficients of which are contained in the difference an
