The present invention relates to the field of air vehicle technologies and provides an unmanned aerial vehicle (UAV), including a vehicle body and arms connected to the vehicle body. The arm is hinged to the vehicle body by using a spherical hinge portion and may be folded or unfolded relative to the vehicle body. Through the forgoing manner, the arm is connected to the vehicle body of the UAV by using the spherical hinge. The arm can be folded and unfolded smoothly without interference, which conforms to known operation habits of users, so that after the entire UAV is folded, the structure becomes more compact and easier to carry. In addition, it can be effectively avoided that the UAV is damaged due to impact in the carrying process.

Equipment and methods that combine the use of wave powered vehicles and unmanned aerial vehicles (UAVs or drones). A UAV can be launched from a wave-powered vehicle, observe another vessel, and report the results of its observation to the wave-powered vehicle, and the wave-powered vehicle can report the results of the observation to a remote location. The UAV can land on water and can then be recovered by the wave-powered vehicle.

A method of fire-fighting is provided based on unmanned aerial vehicles UAV(s) launched from transporter aircrafts to deliver water or fire-retardants or any other fire-fighting materials to a location selected by the fire-fighting personnel. A capability of putting-off high intensity forest fires is provided that stems from the precision and the quantity of material that can be delivered per unit surface per unit time. After releasing the fire-fighting material(s), the UAV reaches a safe altitude from which it flies on autopilot to intercept and then proceed on a pre-programmed route to land per pre-programmed instructions on an airfield from which fire-fighting transporter(s) operate, allowing a high efficiency along the line, from loading the transporter airplanes to maximizing the quantity of material that reach the target, to minimizing the remote-pilot time and up to the recovery system that minimizes the recovery cost and it maximizes UAVs' utilization by a quick turnaround.

An aerial vehicle includes a deformable frame. The deformable frame includes a center frame and two arm assemblies. The two arm assemblies are disposed at two sides of the center frame respectively, and are rotatably connected to the center frame, to enable the deformable frame to switch between an unfolded state and a folded state. Each arm assembly includes a deformable rod and a cross rod. The deformable rod includes a first end rotatably connected to the center frame, and a second end rotatably connected to the cross rod and having a height larger than the first end. In the unfolded state, second ends of the deformable rods in the two arm assemblies are away from the center frame. In the folded state, the deformable rods in the two arm assemblies are stacked above the center frame. The aerial vehicle further includes a loading mounted on the center frame.

A system for launching an Unmanned Aerial Vehicle (UAV), comprising: a capsule comprising at least two parts; a UAV configured to be encapsulated inside the capsule in a folded configuration; and an aerial carrier comprising a release mechanism, the carrier configured to carry the capsule; the carrier further configured to be launched and eject the capsule upon arrival at a desired aerial location, using the release mechanism; wherein prior to the ejection, the carrier is further configured to execute vertical maneuvers in order to reduce the carrier's speed and change the carrier's angle thereby creating suitable conditions for the capsule's ejection; the capsule configured to split and release the UAV upon being ejected; and the ejected UAV further configured to unfold upon release from the capsule.

A system for neutralizing target aerial vehicles comprises a projectile launching mechanism that launches a projectile that supports a counter-attack unmanned aerial vehicle (UAV) having an aerial vehicle countermeasure. The counter-attack UAV can be folded in the projectile, and operable to unfold when separated from the projectile. The system comprises an aerial vehicle detection system comprising a detection sensor that detects a target aerial vehicle. Upon detection, the projectile launching mechanisms launches the projectile, and the counter-attack UAV is thereafter separated from the projectile to operate in flight to neutralize the detected target aerial vehicle with the aerial vehicle countermeasure. The projectile launching mechanism can comprise a movable platform comprising a plurality of projectiles and counter-attack UAVs, and can comprise a detection sensor to detect target aerial vehicles.

Disclosed is a drone configured for multiple uses. The drone may include a body and a sensor configured to be attached to the body. Further, the drone may include a plurality of arms configured to be attached to the body. Further, a first end of an arm of the plurality of arms may be attached to the body at a first movable joint. Further, the arm may include a first part connected to the first movable joint. Further, the arm may include a second part attached to the first part at a second movable joint. Further, the arm may include a powered rotor including a shaft configured to provide rotatory motion. Further, the powered rotor may be attached to one or more of the first part and the second part. Further, the drone may include a plurality of propeller blades attached to the shaft.

A shock resistant fuselage system includes first and second fuselage side walls, each of the first and second fuselage side walls having a plurality of guide posts, and a printed circuit board (PCB) rigidly attached to at least one of the first and second fuselage side walls, the PCB having a plurality of guide slots, each of the plurality of guide posts slideably seated in a respective one of the plurality of guide slots so that elastic deformation of the PCB is guided by the guide slots between the first and second fuselage side walls.

An unmanned aerial vehicle (UAV) includes a central body, a plurality of arms extending out from the central body and in fluid communication with the central body, and a plurality of propulsion units. The plurality of arms are configured to route fluid away from the central body of the UAV. Each propulsion unit attached to a corresponding arm of the plurality of arms.

A fact checking system utilizes social networking information and analyzes and determines the factual accuracy of information and/or characterizes the information by comparing the information with source information. The social networking fact checking system automatically monitors information, processes the information, fact checks the information and/or provides a status of the information, including automatically modifying a web page to include the fact check results. The fact checking system is able to be implemented utilizing a drone device. The drone device is able to be implemented in conjunction with a security system.
