The ferromagnetic material is within the housing, the ferromagnetic material being continuous in an up-and-down direction of the housing. The power transmission coil is within the housing, the power transmission coil being configured to surround the ferromagnetic material.

An apparatus (1) for changing a power source of a drone, the apparatus (1) comprises an adaptor (2) for securing a power source (3) to a drone and comprising a first energy connection for supplying energy from the power source (3) and a second energy connection for supplying energy to a drone, wherein one of the first and second energy connections comprises a pair of energy links (20, 21) which are movable between a first position (FIG. 5) to facilitate energy supply and secure the power source (3) to the drone and a second position (FIG. 4) to interrupt energy supply and enable the power source (3) to be removed from the drone.

An unmanned aerial vehicle includes a fuselage, a power device connected to the fuselage, and a control device disposed at the fuselage and electrically connected with the power device. The control device is configured to control the power device to switch an operating mode of the power device to cause the unmanned aerial vehicle to fly in air or navigate on a water surface. The control device includes a depth detector and a main controller. The depth detector is configured to detect a water depth. The main controller is configured to control the unmanned aerial vehicle not to land in response to the depth detector determining that the depth falls within a pre-depth range.

An aircraft capable of vertical take-off and landing comprises a fuselage, at least one processor carried by the fuselage and a pair of aerodynamic, lift-generating wings extending from the fuselage. A plurality of vectoring rotors are rotatably carried by the fuselage so as to be rotatable between a substantially vertical configuration relative to the fuselage for vertical take-off and landing and a substantially horizontal configuration relative to the fuselage for horizontal flight. The vectoring rotors are unsupported by the first pair of wings. The wings may be modular and removably connected to the fuselage and configured to be interchangeable with an alternate pair of wings. A cargo container may be secured to the underside of the fuselage, and the cargo container may be modular and interchangeable with an alternate cargo container.

An unmanned aerial vehicle (UAV) assembly includes an UAV and an UAV docking station. The UAV docking station includes a housing, an extension piece, and a door. The housing is provided with an accommodation cavity and a hatch communicating with the accommodation cavity. The extension piece comprises an extension cavity and is connected to the housing. The extension piece is disposed on a side portion of a housing end which is near the hatch, and the extension cavity communicates with the accommodation cavity. The door is connected to the housing and disposed at the hatch, and the door is configured to open or close the hatch. A cross-sectional area where the extension cavity communicates with the accommodation cavity is greater than a cross-sectional area of the accommodation cavity. The UAV can be accommodated in the accommodation cavity of the UAV docking station.

A drone-assisted ballistic system is provided. The ballistic system may include a plurality of mobile devices, a ballistic computer, and a data interface. Each mobile device may be operable to gather wind data along or adjacent to a flight path of a projectile to a target, each mobile device measuring at least wind speed and wind direction. The ballistic system may include at least one static device operable to gather wind data at or near a launch or firing position. The ballistic computer may be in data communication with the plurality of mobile devices to receive the wind data. The ballistic computer may be configured to calculate a wind compensation value for the projectile based on the wind data. The data interface may be in data communication with the ballistic computer to output the wind compensation value to a user in real-time.

The invention relates to an assembly comprising an unmanned transport device for delivering a shipment and a transfer device, said transfer device being designed to lower the shipment from the unmanned transport device to a receiving container, to lift the shipment from the receiving container to the transport device and/or to transfer said shipment between the transport device and the receiving container, the shipment being guided in each case by the transfer device.

Intermodal vehicles may be loaded with items and an aerial vehicle, and directed to travel to areas where demand for the items is known or anticipated. The intermodal vehicles may be coupled to locomotives, container ships, road tractors or other vehicles, and equipped with systems for loading one or more items onto the aerial vehicle, and for launching or retrieving the aerial vehicle while the intermodal vehicles are in motion. The areas where the demand is known or anticipated may be identified on any basis, including but not limited to past histories of purchases or deliveries to such areas, or events that are scheduled to occur in such areas. Additionally, intermodal vehicles may be loaded with replacement parts and/or inspection equipment, and configured to conduct repairs, servicing operations or inspections on aerial vehicles within the intermodal vehicles, while the intermodal vehicles are in motion.

A coupling mechanism for coupling a light vehicle to a surface, the coupling mechanism comprising: a magnetic coupling device arranged such that it may be switched between a first mode and a second mode, wherein in the first mode the device generates an external magnetic field less than a first strength, and in the second mode the device generates an external magnetic field of at least a second strength, the second strength being greater than the first strength; and a surface detection unit, coupled to the magnetic coupling device, and arranged to determine when the light vehicle is within a predetermined distance of a surface, wherein in response to the surface detection unit determining that the light vehicle is within the predetermined distance, switching the magnetic coupling device from the first mode to the second mode, to secure the light vehicle to the surface.
