    Abstract: There is described an antireflection surface having a predetermined roughness so as to keep the reflectivity of incident radiation low. A profile with projections having a height (h) which is an integer multiple of the radiation wavelength can trap the radiation irrespective from its polarization and also at large angles of incident light.

    Abstract: The radiation beam emitted by a polychromatic source of finite dimension is incident onto an array of microlenses which have the function of converging and dividing the beam into a plurality of microbeams directed towards a matrix containing coloured microfilters. Once the microfilters have been passed, the radiation reaches a matrix of microchoppers which can be selected independently from each other by a controller, for generating images.

    Abstract: Described herein is a fuel-cell stack (20), which comprises a plurality of direct-alcohol fuel cells (FC) electrically connected together. Each cell (FC) has a miniaturized structure comprising a first electrode, a second electrode, an electrolyte set between the first electrode and the second electrode, means for conducting electrical current to the first electrode, and means for conducting electrical current to the second electrode. The miniaturized structure of each cell (FC) is made up of a plurality of layers set on top of one another, and the various miniaturized structures are associated in an unremovable way to a flexible substrate (21) capable of being wound up in a roll.

    Abstract: A flat panel lighting device 1 comprises: a plate of transparent material 2, on which is applied an array of electroluminescent point sources 3 (such as LEDs, quantum wells or laser diodes); a second plate 7 which collimates light from the sources 3; an electrically and thermally conductive layer 4 (which may be transparent) connecting first electrodes of sources 3; and a second conductive layer (6, fig. 2) connecting second electrodes of sources 3. The collimating means 7 may be an array of microprojections with a reflective layer (8, fig.3), refractive microlenses, or a diffraction grating.
