Abstract: A car having: two front wheels; two rear wheels; an opposed-piston internal combustion engine and having: a crankcase, a number of cylinders obtained in the crankcase, a number of pistons twice the number of the cylinders as two opposed pistons slide in each cylinder, and two crankshafts, which are longitudinally oriented and are each connected to a respective half of the pistons arranged on a same side of the crankcase; and a gearbox, which is connected to the crankshafts of the internal combustion engine and is arranged behind the internal combustion engine. The gearbox has two clutches, each separate and far from the other clutch and connected to a corresponding crankshaft, and two input shafts, each connected to a respective clutch.

Abstract: A car having: two front wheels; two rear drive wheels; an internal combustion engine which is provided with a plurality of cylinders inside which respective pistons slide and with a drive shaft connected to the pistons, and arranged longitudinally in a central or rear position; and a transmission system which connects the drive shaft of the internal combustion engine to the rear drive wheels. The internal combustion engine is oriented vertically with the drive shaft arranged higher than the cylinders.

Abstract: Described herein is a container for video or photographic image-taking apparatuses comprising a casing that includes a housing for housing an image-taking apparatus, said casing comprising a transparent window, an inner surface of which faces a lens of said image-taking apparatus, said casing comprising a sheet wound on itself in a spiral, in particular about a main axis thereof, so as to define between its own facing surfaces a spiral-shaped path, said housing being comprised in the innermost turn of said spiral-shaped path, said container comprising a delivery duct coupled to said housing, in particular to said image-taking apparatus, and configured to convey a temperature-regulating gas, in particular air, at a given temperature into said housing and into said spiral-shaped path.

Abstract: The present invention concerns an active electronically scanned array antenna comprising: an active array, configured for radiating/receiving radiofrequency signals through first radiating openings that lie on a ground plane; and a dielectric cover arranged at a given distance from the ground plane so that between said dielectric cover and said ground plane an air gap is present. Said active electronically scanned array antenna is characterized in that it further comprises one or more calibration devices operable for calibrating said active electronically scanned array antenna, each calibration device comprising a respective radiating portion arranged between the dielectric cover and the ground plane and configured for receiving radiofrequency signals radiated through corresponding first radiating openings and for radiating radiofrequency signals in the air gap towards said corresponding first radiating openings.
