A system and method for releasing and retrieving an Autonomous Underwater Vehicle AUV (3) using an Unmanned Aerial Vehicle UAV (2) where the AUV (3) has a frame structure (6) attached to its outside and the UAV (2) has a latching mechanism (5) attached to a wire (4) for latching on to the frame structure (6) on the AUV (3).

A baler includes a body, and a wrap system that is attached to the body. The wrap system is operable to support a roll of wrap material in an installed position. A cover is attached to the body, and is moveable between an open position and a closed position. When in open position, the cover provides access to the wrap system from an exterior location. When in the closed position, the cover encloses the wrap system from the exterior location. The baler includes a lift system attached to the body. The lift system is concealed between the body and the cover when the cover is disposed in the closed position. The lift system is positioned below the cover when the cover is disposed in the open position. The lift system raises the roll of wrap material into the installed position.

Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly is coupled around and in face-sharing contact with a portion of an outer surface of the motor. Additionally, the contactor assembly may include two or more coils spaced apart from one another within the contactor assembly.

A balancer for tools includes a rotating winding and unwinding drum for a cable, configured with a free end for supporting a tool. The balancer also includes a spring, wound around the main axis of rotation of the drum and integral with a terminal portion with the drum, in order to generate an elastic reaction, as a consequence of the unwinding of the cable and of the consequent rotation of the drum, adapted to facilitate the rewinding of the cable. The balancer further includes an element for braking the drum, which is adapted to generate a resisting moment which acts even indirectly on the drum to contrast the rewinding stroke of the cable; a respective electronic unit is furthermore associated with the element and is provided with a module for the control and adjustment of the intensity of the resisting moment generated by the element.
