Launch and recovery of an aerial vehicle by a forwardly moving surface vehicle relies on a winch module having a winch to selectively reel out and reel in a towline and a sensor capable of sensing tension in the towline. A lifting body assembly having a pair of lifting bodies and a snagging wire is connected to the towline. The lifting bodies lift and laterally extend the snagging wire between the lifting bodies. An aerial vehicle flying through the air engages the snagging wire by a hook. A first signal representative of tension of the towline causes the winch to reel in the towline and to bring the aerial vehicle to the surface vehicle, and a second sensor associated with the hook generates a second signal representative of tension in the hook and causes the aerial vehicle to cut its motor.

A weight-activated tying shoe wherein user who, upon sliding his foot inside the shoe, will depress a movable inner sole. This activates a side mechanism composed of a winch with a cable system used to close the tongue of the shoe towards the user's foot, thus lacing the shoe. The user simply uses his weight to activate the mechanism. Using his other foot, the user can move a pedal to release the mechanism's tension. Most of the mechanical components are located on both sides of the shoe body.

An optical communication system using a high altitude tethered balloon 10 that operates above most clouds and atmospheric turbulence. An optical communication system includes a balloon 10 with an optical communication payload 30, a fiber optic cable attached to the tether 12, an automated winch system 14, and a ground station 28.

An improved mast arrangement for a mobile multi-function rig has a winch line extending from an upper end of the mast and a traveling block supported thereon. A trolley mountable on the mast is adapted for coupling to the traveling block. The trolley works primarily as a guide for a given load, and therefore is of a lightweight design since loads mounted to the trolley are transferred directly to the traveling block and the supporting winch line. The trolley provides the capability to readily switch between various rig operations, including manipulating coiled tubing with an injector, setting surface casing using a top drive, operating the winch and traveling block for joined pipe operations, and interchanging between top drive and joined pipe operations without removing the top drive from the mast or rig. The rig can run deeper joined pipe applications than previous mobile rigs by providing means for employing the top drive, namely the trolley is adapted to counteract the torsion exerted by the top drive during operation. The trolley is able to work the entire length of the mast after quickly parking the injector near the bottom of the mast. The winch and traveling block have unobstructed travel along the entire length of the mast without disengaging the trolley from the mast and with the injector parked near the bottom end.

An electronic winch monitoring system for a winch having a fixed-ratio gearbox with input and output shafts, a winch drum connected to the output shaft, and an auxiliary brake connected to the output shaft activated by reducing the pressure in a brake release hydraulic circuit. The system comprises an input shaft speed sensor, an output shaft speed sensor, and an electronic control unit having a monitoring section and a brake control section. The monitoring section receives the speed signals, processes them to produce a calculated ratio of actual input to output shaft speeds, and produces a fault indication signal when the value of the difference between the calculated speed ratio and the fixed ratio exceeds a predetermined value. The brake control section, upon receiving the fault signal, reduces the hydraulic pressure in the brake circuit using a nonlinear pressure-time profile to engage the auxiliary brake and stop the winch drum.

At its unloading position the vessel has winches (11) with at least three flexible lines (10) that can be connected with horizontally distanced lifting points (23) on the wind turbine base.

A single-tilt-rotor VTOL airplanes have a tiltable rotor attached to an elongated power pod containing the collective and cyclical pitch mechanism, and transmission. The power pod is pivotably attached to a base that is slidably mounted on a pair of slotted guide beams attached on top of the roof of the fuselage. The guide beams run longitudinally from the front of the aircraft to past the center of gravity (CG) of the aircraft in order to transport the power pod from the front section to the center section when converting from the horizontal cruising mode to the VTOL mode. In the horizontal cruising mode, the power pod perched horizontally on top of the fuselage front section with sufficient clearance for the rotor to rotate in front of the aircraft. Upon transitioning to the VTOL mode, a telescopic actuator is used to pivot the power pod vertically while a cable-winch system is used to move the entire power pod and base assembly rearwardly to stop at the center of gravity of the aircraft, and vice versa, thus allowing the power pod to travel significantly rearward and forward as required for proper balancing of vertical lift as the power pod pivots 90 degrees during transition from VTOL mode to the cruising mode. A single piston engine, or a single or pair of turbofan engines, mounted slightly to the rear of the CG, have drive shafts that can be clutched and mated onto respective receiving shaft from the transmission within the power pod in order to power the tiltable rotor. The engine is also attached to a propeller for horizontal propulsion, or if turbofan engines are used, jet thrust is generated for horizontal cruise. A small anti-torque rotor or ducted fan toward the tail of the aircraft is mechanically coupled to the engine via a drive shaft to provide the necessary side-way thrust to overcome the main rotor's torque. In the horizontal cruising mode, the tiltable rotor is allowed to windmill slowly at a minimum rotational speed necessary to maintain the integrity of the rotor blades. The same propulsion principle can be applied to VTOL airplanes having more than one tiltable rotor, thereby can potentially increase the speed, range and reliability of current twin-wing-mounted-tilt-rotor aircraft. A pair of high-aspect-ratio wings on both sides of the fuselage provide highly efficient lift during cruising flight with very little induced drag. Conventional horizontal and vertical tail planes are used for directional stability in the cruising mode.

A stabilized UAV recovery system is disclosed. In the illustrative embodiment for UAV recovery over water, the system includes ship-based elements and UAV-based elements. The ship-based elements include a robot arm that holds a capture mechanism over the side of the ship while compensating for wave-induced ship motion. The UAV-based elements include a hook mounted to the top of the UAV fuselage. With the capture mechanism held stable from the perspective of a UAV approaching from behind or in front of the mechanism, the UAV is flown under it, snagging an arresting line with the hook. With continued forward motion of the UAV, the arresting line pulls out of a winch drum that is coupled to a brake, bringing the UAV to rest.

Device, system and method for sampling of soft sediments with retention of sample material and profile. A barge is anchored and stabilized in position; sampling tubes are driven through underlying sediments using continuous and controllable translational pneumatic force; a torpedo-shaped end piece leads the sampling tubes into the sediments. Once at desired depth, a rotational force is applied to sampling tubes. Fins located around torpedo prevent the torpedo from rotating and connection between leading sampling tube and torpedo is tightened. O-ring located between torpedo and leading sampling tube is squeezed as a result of such tightening and bulges inward pinching the core inside sampling tube. During retrieval, core is more likely to break at the location of the pinch which has introduced structural discontinuity; core above the pinch is capped by compacted material at the pinch. O-ring does not disturb sample integrity during descent. Winch and pulley mechanism may assist.
