    摘要： A luminous signalling device comprises a body made of transparent synthetic material, basically in the form of a plate having two larger faces set opposite one another, at least one of which carries an image. A plurality of LED devices of the SMD type which emit white light is coupled externally to at least one of the walls that define the peripheral edge of the aforesaid plate body. The arrangement is such that the rays of white light coming out of the LED devices undergo multiple total reflections within the plate body, which thus functions as a light guide. In areas corresponding to selected areas of the image, the face of the plate body is made up of diffusing optical elements designed to diffuse outwards the rays of light that are incident on said areas within the body.

    摘要： A method for making three-dimensional structures of nanometric or micrometric dimensions comprises the following steps: obtaining of a photopolymeric or UV mixture including nanoparticles orientable in space; deposition of a layer of the mixture on a respective substrate; exposure of the layer to UV-radiation and control of the polymerization of the mixture by means of variation of its index of refraction; application of a magnetic and/or electrical field for producing a desired positioning of the nanoparticles, in order to induce the growth of surface projections from the layer of mixture; and polymerization of the mixture.

    摘要： An infrared sensor device for motor-vehicles, designed to detect the presence of an overtaking vehicle, comprising at least two cells sensitive to infrared radiation, placed on one side of the reflecting plate on the outside rear view mirror of a motor-vehicle, behind focusing optics. Each cell emits a signal proportional to the infrared radiation it receives. An electronic circuit emits a global signal proportional to the difference between the signals emitted by the two cells, so that said global signal enables the presence of an overtaking vehicle to be distinguished from that of other vehicles travelling in the opposite direction, as well as avoiding false alarms due to electronic and electromagnetic noise.
