Abstract: A laser 3D printer is provided with: at least two processing stations, each having a respective tubular compartment and a respective lifting platform, which is slidably engaged in the tubular compartment; at least one feed assembly for feeding a powdered material onto the lifting platforms; and at least one laser printing head mobile between the processing stations for sintering the powdered material laid on the corresponding lifting platforms.

Abstract: System and Method to adjust the orientation of a mobile video camera suited to film a pair of athletes moving on a field of play, wherein the position of the athletes is determined relative to a coordinate system integral to the field of play by using radio transmitters, which are applied to the bodies of the athletes, and radio receivers arranged around the field of play, and fixed relative to the field of play and interfaced with a processing and control unit, the processing and control unit determines an intermediate position between the two athletes as a function of the current positions of two athletes, and a motor-driven moving device moves the mobile video camera so as to center the respective camera framing on the intermediate position.
