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

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.
