The present invention relates to a protective foldable cage (100) adapted to flying drones. It comprises several ribs linked at their extremities by a ring and comprising on their length several connexion points allowing strings to join each of the adjacent ribs. The length of the string corresponds to the maximal angular shift between the first and the last ribs. The protective cage further comprises easily removable locking means adapted to maintain the ribs at predetermined relative angular position once deployed. The resent invention further relates to a system comprising such a protective cage and a drone support, as well as a method of protection of flying drones.

Aerial vehicles may be selectively transitioned between a fixed wing flight configuration and a vertical takeoff and landing (VTOL) configuration. In the fixed wing flight configuration, a forward propeller may rotate in a first forward plane, whereas in the VTOL configuration, the forward propeller may be tilted to rotate in a second forward plane. A forward landing arm may extend downward in the VTOL configuration and be configured to be tilted to a stowed position when the aerial vehicle is in the fixed wing flight configuration. The forward landing arm may be coupled to the forward propeller such that tilting of the forward propeller causes corresponding tilting of the forward landing arm. In some examples, a plurality of such landing arms and propellers are tilted during transitioning of the aerial vehicle, such as one or more forward propellers and landing arms and/or one or more aft propellers and landing arms.

A patient transfer device. According to one embodiment, there is provided a patient transfer device: a support part including a patient seating surface on which a patient is supported; a plurality of propeller parts, connected to the support part, for moving the support part; a power supply unit to be transported while being borne by the user, the power supply unit serving to supply power to the plurality of propeller parts; and a connection member connecting the power supply unit and the support part, wherein the support part is configured to move to follow the power supply unit.

An unmanned aerial vehicle capable of vertical takeoff and landing carries a remote sensing platform to a high altitude cruising altitude and flies over a target area, collecting remote sensing imagery before returning to earth. Instead of being piloted remotely, the vehicle employs an autonomous flight control system.

A propeller apparatus of an air mobility includes a housing having an inner space, where multiple slits are formed along a circumferential surface of the housing to extend in a vertical direction; a driving unit having connection portions formed to match respective ones of the slits in the housing; multiple link units configured to match the respective ones of the slits in the housing, where the link units are rotatably connected to the connection portions, respectively, of the driving unit; and multiple wing units configured to be rotated in a manner of being linked with the link units, which rotate when the driving unit moves up and down, thereby being folded to or deployed from the housing. The propeller apparatus is configured to prevent an accident due to scattering of a propeller when the air mobility falls, and to improve space utilization during storage of the air mobility.

An unmanned aerial vehicle including a housing, a first front arm, a first back arm, a second front arm, and a second back arm. The first front arm has an end at a first elevational plane when in a closed position. The first back arm has an end at a second elevational plane when in the closed position, the second elevational plane higher than the first elevational plane to provide an offset. The second front arm has an end at the first elevational plane when in the closed position. The second back arm has an end at the second elevational plane when in the closed position, the second elevational plane higher than the first elevational plane to provide the offset.

An unmanned system maneuver controller (USMC) includes an inertial navigation system (INS) for state estimation of the USMC in three-dimensional (3D) space, a communications device configured to communicate with an unmanned system, and a processor configured to receive, via the communications device, flight, maneuver, or dive data from the unmanned system, and generate flight, maneuver, or dive control instructions based at least on the flight, maneuver, or dive data and data received from the INS. The flight, maneuver, or dive control instructions are configured to pilot the unmanned system based on movement of the USMC in 3D space. A remote may selectively control an operation of the USMC. The USMC may be mounted to a weapon or observation device, such that movement of the weapon or observation device in 3D space controls a movement of the unmanned system. Additional systems and associated methods are also provided.
