A control system for a rescue hoist attached to an aircraft is disclosed. In various embodiments, the control system includes a first bus extending between a control module of the rescue hoist and a control input device; and a second bus extending between the control module of the rescue hoist and the control input device. The first bus is configured to transmit a first signal from the control input device to the control module and the second bus is configured to transmit a second signal from the control input device to the control module, both the first signal and the second signal being generated by the control input device in response to a manipulation of the control input device.

A method for passive aerial cord release mechanisms and an aerial cord release mechanism for an aerial vehicle (AV). A method includes determining a retracting force to be applied to a winch of an aerial vehicle (AV), wherein the determined retracting force is a force required to retract a cord to be coiled around the winch within the AV, and the cord is temporarily coupled to the winch, such that an external force exceeding a predetermined threshold causes decoupling between the cord and the winch.

A system for controlling a winch assembly includes a rotatable winch drum with an attached cable. A winch motor is configured to rotate the winch drum. A sensor is configured to generate signals indicative of the number of layers of the winch cable on the winch drum. A winch controller is configured to receive a control input requesting a selected rotation of the winch drum, receive the signals from the sensor, determine a number of layers of the winch cable disposed on the winch drum, and generate control commands to control the winch motor to rotate the winch drum based on the control input and the number of layers of the winch cable. The control command rotates the winch drum to produce a substantially constant line speed based on the selected control input independent of the number of layers determined to be disposed on the winch drum.

An apparatus and a method for controlling a vehicle winch, and a storage medium. The apparatus includes an instant control component and a delay control component. The instant control component is configured to start the winch and control a rotation direction of the winch. The delay control component is configured to acquire a running parameter of the winch and shut off the winch according to the running parameter.

An unmanned aerial vehicle according to certain embodiments generally includes a chassis, a power supply mounted to the chassis, a control system operable to receive power from the power supply, at least one rotor operable to generate lift under control of the control system, a line having one end coupled to the chassis and an opposite free end, wherein the free end is positioned below the chassis, and a severing mechanism operable to sever the line under control of the control system.

A hoisting mechanism of a crane comprising at least one rope drum for a hoist rope, at least one hoist motor for driving the rope drum, a gearing coupled between the rope drum and the hoist motor, and having an input gear on the hoist motor side and an output gear on the rope drum side, and a brake for braking the input gear. The gearing has a differential to which a first input gear and a second input gear are arranged, wherein the first input gear and the second input gear are coupled to each other and further coupled to the output gear, wherein a first hoist motor connected to the first input gear, and a second hoist motor connected to the second input gear are arranged, and wherein the first input gear and the second input gear have unequal total gear ratios relative to an output shaft. The invention also relates to a method for operating this hoisting mechanism.

In an integrated structure of a power source of a power winch and an electric control box, the electric control box of the power winch is integrally combined with the top of the power source by a support frame, and an outer cover is provided for axially covering the electric control box and the power source and locked and connected to a front shell wall, so that the electric control box and the power source are completely hidden in the outer cover without any exposure. In other words, the electric control box is combined with the power source by a hidden assembly mode, so that the electric control box can be securely assembled without any risk of being shaken or falling off. In the meantime, the electric control box is hidden in the outer cover, and thus it will not be affected by weather at all.

A system has a hoist system to lift a payload to a position adjacent to a ceiling of a room Image sensor systems collect visual data and payload depth data within the payload and ambient depth data within the room. A controller is connected to the hoist system and the image sensor systems. The controller is configured to control the motion of the hoist system. The motion of the hoist system is controlled in part by the ambient depth data from the room.
