    Abstract: The present invention discloses a device for evaluating the technical condition of the tread of moving railway vehicles, especially for automated inspection of the loss of roundness of each wheel of circulating railway vehicles, in which a point of measurement is used which generates a signal proportional to rail deformation when a wheel arch passes over said point. Then the comparator system compares the measured signal with a wheel pattern without any roundness defects, which is then transmitted over a data network that associates the wheel identification information, with the wheel defect data generated by the comparator system each time the wheel passes over said measurement area.

    Abstract: This invention relates to a device with function for measuring volumetric changes in a substance. In particular, the device with function for measuring volumetric changes in a substance comprises a sensor that detects the amount of light intensity produced by a light source aligned with said sensor when passing through a column of two liquids which are immiscible among each other contained in a transparent tube, wherein the sensor and the aligned light source are mounted on an arm that travels on a vertically arranged rail, wherein the arm is attached to a strap which acts by means of a first and a second pulley causing the movement of said arm, wherein the movement of said pulleys comes from a motor and a gearbox and the entire mobility system is mounted on a frame. The device further comprises data acquisition means which record the change of light intensity and control the arm movement.

    Abstract: The present invention relates to a covering with optoelectronic elements, which uses a cover to optimize light distribution to absorb or emit optical radiation. The cover diverts optical radiation originating from external optical sources or optoelectronic elements contained in the covering, to maximize the absorption or dispersion of the optical radiation. The optoelectronic elements absorb or emit optical radiation, which is used to generate photovoltaic energy by using photovoltaic cells or to measure radiation by means of sensors of ultraviolet, infrared or visible radiation, inter alia, or to emit optical radiation by means of light-emitting elements such as LEDs, lasers, incandescent bulbs, and fluorescent lamps, inter alia. The cover and the optoelectronic elements are supported by a base that contains securing elements.
