摘要:
The polychromatic or monochromatic radiation beam emitted by a light source strikes an array of micro-filters which partially or totally transmit the light beam towards an array of micro-mirrors. The partially reflected beam comes back towards the first array of micro-filters and passes again through it until it reaches a viewer or a recording system or a screen. A relative movement between the two arrays of micro-filters and micro-mirrors enables static or animated images or colour strips selectable according to the needs to be generated.

Described herein is a fuel-cell stack, which comprises a plurality of direct-alcohol fuel cells electrically connected together. Each cell 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 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 capable of being wound up in a roll.

Described herein is a microgenerator of electrical energy with a high power density, which uses an internal-combustion micromotor with two combustion chambers set opposite to one another, within which a piston is displaced with reciprocating motion. The piston is at least in part made of magnetic material and is wound with a coil, within which is generated an electric current by induction. The fuel, the oxidant, and preferably a catalyst, are injected into each of the two combustion chambers by means of injectors that are substantially of the same type as those used in ink-jet printer heads. The dimensions of the device are comparable to those of a 1.5-V NiCd battery of a traditional standard type.

VTOL aircraft comprising a first and a second ducted rotor positioned at the ends of a vertical fuselage and whose propellers are driven to rotate in mutually opposite directions. Control flaps for orientation and transverse flight are operatively associated at least to the lower ducted rotor.
摘要:
VTOL micro-aircraft comprising a first and a second ducted rotor mutually aligned and distanced according to a common axis and whose propellers are driven in rotation in mutually opposite directions. Between the two ducted rotors are positioned a fuselage and a wing system formed by wing profiles forming an X or an H configuration and provided with control flaps.
摘要:
An electric generator device comprising a panel bearing one or more electric generating machines each including a stator and a rotor concentric and substantially co-planar. The rotor is supported in rotation by the stator and presents a central part bearing one or more blades of a fan. A flow of fluid causes the fan and in consequence the rotor (R) to rotate. The rotor bears along its periphery a plurality of magnetic poles whose magnetic fields link with windings borne by the stator, for the induction of an electric current in the windings. The rotor is supported in rotation within the stator through magnetic means of support.

An antireflection surface having a predetermined roughness so as to keep the reflectivity of incident radiation low. A profile with projections having a height 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.

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.
