Patent number: 10827650Abstract: The systems and methods described herein provide a submarine optical repeater in which a plurality of thermally conductive, electrically insulative, ceramic members form a hollow structure having an interior volume that is maintained at a relatively high first voltage when compared to a relatively low second voltage maintained external to the hollow structure. A conductive element at the first voltage disposed in the interior volume provides power to optical repeaters disposed on the interior surface of the hollow structure. Power flows radially outward from the conductive element to the optical repeaters to the surrounding environment about the submarine optical repeater. The thermally conductive ceramic members electrically isolate the optical repeaters from the second voltage while providing a thermally conductive pathway for the heat generated during the operation of the optical repeaters to dissipate into the surrounding environment.Type: GrantFiled: April 5, 2019Date of Patent: November 3, 2020Assignee: IPG PHOTONICS CORPORATIONInventor: Sergio Walter Grassi

Patent number: 8079215Abstract: System for controlling the motion of an actuator of a hydraulic system that may be embodied as a circuit or device that, interposed between a pump and the actuator, controls the motion of the actuator, causing the actuator to follow the movement of the pump. The present invention relates both to a system and a device providing such result just on the basis of the measures of the fluid circulating within the hydraulic circuit or device. The system according to the present invention is suited both with opposing loads and dragging loads.Type: GrantFiled: April 24, 2006Date of Patent: December 20, 2011Assignee: Inova SRLInventor: Sergio Walter Grassi
