Abstract: Transducer assembly transmits ultrasonic energy towards a zone acoustically coupled to an object or area of interest, and comprises a piezoelectric subassembly matching a curved support layer disposed behind said subassembly. Piezoelectric subassembly comprises piezoelectric elements and metal connections. Piezoelectric elements are disposed along a first azimuth direction to form parallel curved segments of piezoelectric elements extending in a second elevation direction, each being in contact with a corresponding metal connection extending in the elevation direction for transmitting/receiving electric signals to/from each piezoelectric segment.

Abstract: A transducer assembly operable to transmit ultrasonic energy in a desired direction towards a zone adapted to be acoustically coupled to an object or area of interest is provided that has: a transducer layer; a backing layer disposed behind said transducer layer with respect to the desired direction; a back-matching layer disposed between the transducer layer and the backing layer to reflect towards said transducer layer part of the ultrasonic energy directed from the transducer layer to the backing layer; and a heat transfer layer disposed between the back-matching layer and the backing layer to drain heat from the transducer assembly. A process for manufacturing a transducer assembly is also disclosed.

Abstract: A lamp for lighting large, indoor and outdoor environments, comprising a LED light source supported by a LED-holder base interposed between a heat sink and a focusing lens. Said base features such configuration and characteristics as to provide, together with two retaining rings and a deformable core hitch, for a high degree of protection against penetration of solid bodies and liquids and for a high thermal dissipation towards the external environment.
