摘要:
An electrical energy generator device comprising an array of micro-fans each associated to a respective dynamo-electric generator by means of a respective connecting shaft, further comprises, for at least some of the micro-fans (3), a lug element (6) associated to the respective connecting shaft (4) which mechanically co-operates at each revolution with a piezoelectric element (7), for the production of additional electrical energy. In addition or instead of the aforesaid arrangement, it is possible to provide plates (10) made of piezoelectric material which vibrate in the flow of air that invests them, thereby producing electrical energy.
摘要:
A motor vehicle air conditioning system including a Coanda effect air distributor device and mixing means which allow to vary the temperature of the air available to the different outlet conduits of the distributor device for the same setting of the means for regulating the temperature of the system. In this way, for a same setting of the temperature regulating means, the air conveyed to the outlets situated at the base of the windshield is at a higher temperature than the air conveyed to the other outlets and in particular to those adjacent to the floor of the motor vehicle passenger compartment. Preferably, a third, still lower temperature level is available to the outlets situated in the front part of the dashboard of the motor vehicle in the direction of the motor vehicle occupants.

摘要:
A shape memory bistable actuator includes an element movable mounted on a fixed support structure, having an intermediate position of dead center and two end positions. Spring means tend to return the movable element towards either end positions, depending on that it is on either part with respect to the dead center position. Shape memory means are provided for causing a displacement of the movable element from either end positions, against the action of the spring means, at least until the dead center position is exceeded. After this exceeding, the activation of the shape memory means can be stopped, as the spring means provide to proceed the movable element toward the new desired working position, and to hold it in such a position, despite the shape memory means are deactivated.

A motor-vehicle dashboard incorporating an air distribution system that includes suitable means for controlling the deviation of airflow in the various ducts (3) associated with the outlet vents (2) on the dashboard, using the Coanda effect.
摘要:
A system for the distribution of air to a row of seats in a passenger compartment of a means of transport, such as for example an aeroplane, train or bus, or in the room of a building, comprises a main duct and a series of outlets. The outlets are without valves for opening and closing, and the flow of the air through the outlets is controlled by control means associated to each outlet that exploit the Coanda effect.
