Abstract: In an embodiment, an RF device comprises: a test RF connector, a device housing, the device housing comprising at least one conductive portion, and a grounding connector configured to electrically connect the at least one conductive portion to a ground of the test RF connector.

Abstract: The present invention describes a nanocomposite and hybride material of functionalized carbon nanotubes and cellulose and associated methods for the fabrication of that nanocomposite or hybride material containing electromagnetically active nanoparticles. The fabrication is fast, environmentally friendly, and economical. These nanocomposites are strong and electrically conducting, and have many materials and electronic applications.

Abstract: A web-forming section of a paper or board machine has a first web-forming unit with a first fiber layer (W1) formed on a first wire (10); a second web-forming unit with a second fiber layer (W2) formed on a second wire (30); and a couch shoe (39) over a curved deck (40) of which the fiber layers (W1, W2) are guided for joining them together. The second fiber layer (W2) is brought to the couch shoe (39) at an angle (?) of less than 20°, advantageously less than 15° in relation to the approach direction of the first fiber layer (W1). The couch shoe (39) is provided with underpressure and the radius of curvature of its deck (40) is usually larger than the radius of curvature of a guide roll (38) preceding it. By the couch shoe, the fiber layers can be joined together wetter than usual.
