    Abstract: The integrated device comprises an epitaxial layer (22) forming a first and a second region (23, 45) separated by at least one air gap (24). The first region (23) forms, for example, a suspended mass of an accelerometer. A bridge element (26) extends on the air gap (24) and has a suspended electrical connection line (28) electrically connecting the first and the second region (23, 45) and a protective structure (29) of etch-resistant material, which surrounds the electrical connection line (28) on all sides. The protective structure (29) is formed by a lower portion (31a) of silicon nitride and an upper portion (32a) of silicon carbide, the silicon carbide surrounding the electrical connection line (28) at the upper and lateral sides.

    Abstract: A photovoltaic device comprising a plurality of photovoltaic cells of different spectral sensitivity, disposed on respective areas of inner surfaces of a hermetically sealed box-like body provided with a transparent pupil with antireflection treatment of its surface, is proposed. Through the pupil, a concentrated beam of collected radiation enters the device and a plurality of dichroic filters arranged in cascade on the optical axis of the transparent input pupil split the concentrated beam in distinct beams of different spectrum. As many mirrors, each having multiple reflecting surfaces, intercept respective beams of spectral subdivision, and the multiple reflecting surfaces redirect the radiation in form of a plurality of reflected beams each directed to illuminate the active area of a photovoltaic cells of a respective array.
