  • Keyboard based in polymer, copolymer or composites with piezo- and/or pyroelectric properties and respective use
    Patent number: 8314722
    Abstract: The invention refers to a new keyboard based in a polymeric, copolymeric or composite film (11) with piezo- and pyroelectric properties capable of receiving a tactile signal and giving a respond in the form of an electrical signal. The system described in this invention includes one or more keys (10), being each one of them made by a piezoelectric film (11) with electric conductive contacts, transparent or not, above and below the piezoelectric film and with the inferior layer of grounded electrodes (13).
    Type: Grant

  • X-RAY IMAGING MATRIX WITH LIGHT GUIDES AND INTELLIGENT PIXEL SENSORS, RADIATION OR HIGH ENERGY PARTICLE DETECTOR DEVICES THAT CONTAIN IT, ITS FABRICATION PROCESS AND ITS USE
    Publication number: 20090146070
    Abstract: The present invention refers to a radiation or high energy particles detector, which can be used in obtaining digital radiographic images. The detector is composed of two parts: a scintillator matrix (30) embedded in walls manufactured from a reflector material (10), and a matrix of image elements (pixels), where each element is constituted by a photodetector (21) and an analog to digital converter. The walls manufactured from the reflector material (10) form light guides that prevent the dispersion of the visible light produced by the scintillators (30) and the consequent interference between each pixel and its neighbors.

  • Non-Porous Polyvinylidene Fluoride (Pvdf) Films in the Beta Phase and Processing Method Thereof
    Publication number: 20080203619
    Abstract: The invention reports a new film of the beta phase of polyvinylidene fluoride (PVDF) and its processing for the elimination of porosity, using a compression force along the thickness direction of the sample at a high temperature. The join action of the compression force and the temperature eliminates the porosity of the PVDF beta phase, improving its mechanical (Young's modulus, yielding and breaking stress, yielding and breaking strain), electrical (dielectric constant, electric rupture) and electromechanical properties (electromechanical coupling, piezoelectric coefficients) and, therefore, the use of the material in technological applications.
