  • System for controlling noxious emissions in exhaust gases of an internal-combustion engine of a motor vehicle by means of an IR spectrophotometer on board the motor vehicle
    Publication number: 20050120707
    Abstract: Noxious emissions present in the exhaust gases of an internal-combustion engine of a motor vehicle are controlled by making use of an IR spectrophotometer provided on board the motor vehicle, for the purpose of obtaining an analysis of all the main components of the exhaust gases of the engine. The IR spectrophotometer is of the type with electrostatic micro-shutters so as to present overall dimensions designed to enable its use on board the motor vehicle.

  • Micromirror with electrostatically controlled microshutter, matrix of micromirrors and infrared spectrophotometer comprising said matrix
    Patent number: 6888142
    Abstract: An optic device with a variable operating mode comprises a micromirror which can be obscured by means of an electrostatically controlled microshutter. In the operating condition of the microshutter, the petal of this adheres over a substrate to allow a beam of light to reach the mirror. In the condition at rest, the petal is curled up and one of its surfaces receives the beam of light and reflects it in all directions, at the same time preventing this from reaching the mirror.

  • Optical biosensor
    Publication number: 20050019799
    Abstract: The present invention relates to an optical biosensor comprising a porous matrix. In the specific case, reference is made to anodized porous alumina, on the surface of which the biological component specific for the analyte in question is immobilized, and to an optical-signal detector connected to said matrix. The present patent further relates to a biosensor having the porous matrix and the optical detector integrated in a single structure, in particular to biosensors with porous matrix other than porous alumina, for example porous silicon.

  • Method and device for ejecting micro-drops of liquid
    Publication number: 20040257408
    Abstract: Method for ejecting micro-drops of liquid, including the steps of providing a body (18) equipped with at least one passage (30) communicating with a tank (12) of liquid (14), and producing in the passage (30) a choke or a widening that is moveable along a direction of ejection (46), in such a way as to produce the ejection of controlled quantities of liquid (48) from one end (34) of said passage (30).

  • Shape memory thin micro-actuator, and method for producing the same
    Publication number: 20040227427
    Abstract: A micro-actuator includes a shape memory thin film having one end fixed to a substrate and one remaining part which, at room temperature, is in the martensitic phase and assumes a curly-configuration, whereas at a higher temperature than a threshold value it changes to the austenitic condition, wherein the film is completely stretched upon the substrate.
