Abstract:
A measuring system for determining 3D coordinates of measurement points on an object surface which has a scanning apparatus for measuring the measurement points on the object surface and for determining inner measurement point coordinates in an inner scanning coordinate system. Furthermore, a referencing arrangement for producing referencing information for referencing the inner measurement point coordinates in the outer object coordinate system and an evaluation unit for determining the 3D coordinates of the measurement points in the outer object coordinate system on the basis of the inner measurement point coordinates and the referencing information are provided such that the inner measurement point coordinates are in the form of 3D coordinates in the outer object coordinate system. The scanning apparatus is in this case carried in an unmanned, controllable, automotive air vehicle.
Abstract:
An aerially deployed illumination system is provided which may be remotely operated or preprogrammed to illuminate a designated target, such as a geographic area, vehicle, or personnel. In particular, a remotely controlled UAV having an illumination system disposed thereon is provided, the illumination system comprised of a concentrated light source and light movement apparatus operable to rapidly scan the target with the light source, thereby providing an illusion of a large area of illumination. Preferably, a line is created from the light source, the line being rapidly moved over the target in specific patterns and at specific frequencies. The system may further include a plurality of UAV's capable of ad hoc networking, so as to illuminate both large areas, as well as stationary and moving targets. In addition, the UAV's having an illumination system disposed thereon may be disposed within a projectile, the projectile tube or gun launched, and the UAV ejected from the projectile over a designated target, thereby enabling quick delivery of the UAV to an area of interest.

Abstract:
Turret assemblies for small aerial platforms, including unmanned aircraft, and associated methods are disclosed herein. In one embodiment, an aircraft system can include a turret assembly having a payload with a line of sight to a target and a gimbal system carrying the payload. The gimbal system can include (a) a first support coupled to a first actuator to rotate about a first axis, and (b) a second support carried by the first support and coupled to a second actuator to rotate about a second axis generally transverse to the first axis. The payload can be carried by the second support. A housing at least partially surrounds the payload and the gimbal system. The turret assembly can also include a controller configured to direct movement of at least one of the first actuator and the second actuator such that the line of sight is pointed away from a point of impact before the turret assembly contacts the ground or another external structure during landing or capture operations.
Abstract:
Methods and apparatuses for launching unmanned aircraft and other flight devices or projectiles are described. In one embodiment, the aircraft can be launched from an apparatus that includes a launch carriage that moves along a launch guide. The carriage can accelerate when portions of the carriage and/or the launch guide move relative to each other. A gripper carried by the launch carriage can have at least one grip portion in contact with the aircraft while the launch carriage accelerates along the launch axis. The at least one grip portion can move out of contact with the aircraft as the launch carriage decelerates, releasing the aircraft for takeoff. A brake can arrest the motion of the gripper after launch.
Abstract:
A wireless-controlled airplane includes a flying unit and an on-ground controller which is connected to the flying unit through a communication section and flies the flying unit. The flying unit includes a body, a drive section installed on the body, a propulsion apparatus which generates a propulsive force when driven by the drive section, a main wing including a plurality of wing elements which are installed so as to be able to move with respect to each other, an opening and closing mechanism which changes the relative positions of the wing elements to change the effective area of the main wing, and a dropping apparatus which selectively holds and drops a load. By changing the effective area of the main wing, the flight speed can be changed, so the capacity and size of the drive section for rotating the propulsion apparatus can be decreased.

Abstract:
A micro air vehicle having a bendable wing enabling the micro air vehicle to fly. The bendable wing may be bent downwards so that the wingspan may be reduced for storing the micro air vehicle. The bendable wing may be formed from one or more layers of material, and the wing may have a camber such that a concave surface of the wing faces downward. The wing may substantially resist flexing upwards and may transfer uplift forces to a central body of the micro air vehicle. In addition, the wing may be bent severely downwards by applying a force to tips of the wing. The micro air vehicle is capable of being stored in a small cylindrical tube and may be deployed from the tube by simply releasing the micro air vehicle from the tube.
Abstract:
A rotary aircraft (rotorcraft) in which the entire aircraft rotates about its center of mass as it flies, and in which the center of mass is located external to the aircraft in the generally triangular region formed by the aircraft's single wing and two propellers. As the aircraft flies, the two propellers provide torque about the center of mass and rotate the wing, which provides lift for the aircraft. The aircraft is controllable via a stationary radio transmitter that sends commands for pitch, roll, yaw and altitude. A receiver in the aircraft uses the transmitted signal to establish the aircraft's instantaneous orientation in combination with the sent commands to generate control signals that drive the propeller motors that affect the aircraft's attitude. Pitch and roll are controlled by pulse width modulation of the propeller motor voltages in order to affect the thrust at specific portions of the aircraft's rotation cycle.
