A device for capturing rendered text is described. The metal matrix composite is composed of a matrix of a light metal alloy and reinforcements formed of metallic fibers mixed in the matrix. The external surface of the component and the external surface of the finishing plate do not protrude from the frontal edges of the collar. The junction has a functional dimension in nanometers, and includes a switching capability provided by both one or more connector species and the pair of crossed wires and a configurable nano-scale wire transistor having a first state that functions as a transistor and a second state that functions as a conducting semiconductor wire. An air outlet cover, attached to the combination of the duct and perforated tray, is adapted to cover the portion of the air outlet opening that does not interface with the duct.
