An unmanned aerial vehicle according to the present disclosure is an unmanned aerial vehicle that can fly in midair and includes a propulsion unit configured to generate a propulsion force for fly in midair, a laser light source configured to illuminate laser light, an imaging unit configured to generate a captured image by capturing vertically below the unmanned aerial vehicle during flight in midair, and a controller configured to control an operation of the propulsion unit. The controller analyzes a captured image, extracts a light spot formed by laser light, measures a positional relationship with another unmanned aerial vehicle based on the extracted light spot, and executes a collision avoidance operation with respect to another unmanned aerial vehicle based on the measured positional relationship.

A drawing apparatus draws an illumination image by illuminating visible light onto a landing point on which a flight vehicle is to land. The drawing apparatus includes a focusing mechanism that executes focusing of the illumination image according to an altitude of the flight vehicle, and an illumination angle adjustment mechanism that adjusts an illumination angle of the visible light toward the landing point.

An exterior aircraft navigation light for an aircraft having a nominal forward flight direction and being able to fly into the nominal forward flight direction as well as into a plurality of further flight directions, such as sideways or backwards, has at least one light emission unit and control circuitry coupled to the at least one light emission unit, wherein the exterior aircraft navigation light is configured such that each of the at least one light emission unit has a unit-specific light emission direction that has a predefined horizontal angle with respect to the nominal forward flight direction, and wherein each of the at least one light emission unit includes a multi-color light source configured to emit red light, white light and green light, and an optical system for conditioning the red light, the white light and the green light emitted by the multi-color light source.

A capture drone is an unmanned flying object that flies in the air. The capture drone includes a capture net that captures other object in the air, a weight capture determining unit that detects that the capture net has captured the object, and an autonomous flight controller that controls a flight state of the capture drone to be an autonomous flight state not dependent on an operation signal from the outside if the weight capture determining unit detects the capture of the object.

Falling drone warning apparatuses and methods are disclosed. The apparatus may be attached to a drone and may measure acceleration during the drone's operation in order to ascertain whether the drone is free falling. If the apparatus detects that the drone is free falling, the apparatus may activate an audible alarm to warn people on the ground of the potential danger and to afford them the opportunity to take action to avoid the drone's impact or minimize its effect.

An aircraft includes a fuselage with one or more wings coupled thereto. One or more wheels are also coupled to the fuselage and are configured to allow the aircraft to taxi, take off, and land. A propulsor is used to provide thrust to the fuselage and airflow over the wings. The wings may be fixed in position or may be configured to fold along a line via a hinged system or pivot along an axis. The folding allows the wings to store in a smaller footprint. The fuselage may include one or more safety features. These may include indicator lights configured to illuminate or reflect an amount of light. Additionally, the aircraft may include an occupant safety system with the likes of an airbag and even an anti-lock brake system coupled to the one or more wheels.

An illuminated vehicular sign is provided including a vehicle and luminescent planar sheet. The luminescent planar sheet is constructed to provide illuminated alpha-numeric characters which are mounted to the horizontal planar surfaces of a vehicle. The alpha-numeric characters are mounted substantially horizontally so as to be seen from the air such as by helicopters or planes. The illuminated vehicle sign includes a switching system electrically connected to the luminescent planar panels for selectively controlling the transfer of power from said power source to the luminescent planar panels. The switching system including one or more adjustable variable resistors electrically connected to the luminescent planar panels for allowing one to selectively adjust the wattage provided to them.
