Abstract: A system for landing a mobile platform, such as an Unmanned Aerial Vehicle (“UAV”) and methods for making and using the same. The system can land the UAV by applying a magnetic levitation force upon the UAV and adjusting the applied magnetic levitation force. The system can initiate a landing process to a designated docking station and can guide the UAV to an adjacency of the designated docking station. Once the UAV has entered the adjacency, the magnetic levitation forces can take control of the landing process. During the landing process, certain magnetic sensitive devices installed on the UAV and/or on the designated docking station can be protected by turning them off or by shielding them. The system overcomes disadvantages of currently-available landing systems by restricting a size and weight of the landing arrangements, as well as, avoiding potential damage to the UAV and the designated docking station.

Abstract: A remote controlled flying toy figure has a thrust-powered, weight shifting rudder head. The flying toy figure comprises a head, a body, a propulsion system, and a control system. The head is attached to the body by a flexible support member, making the head securely fixed in flexible relation to the body, thus permitting a yawing motion of the head relative to the body. The propulsion system comprises two independently operable motorized propellers, each of which is attached to opposite ends of a steering bar. The steering bar and head form an integral steering unit. Increasing the thrust from one of the propellers causes the figure to turn in the opposite direction. This increased thrust causes the steering bar to yaw, which moves the center of gravity of the head to the opposite side of the center line of the body, which causes the figure to bank towards the turn.

Abstract: The present invention provides an unconventional and proprietary radio control (RC) or infrared remote control (IR) toy model/airplane which can intentionally shift or change its center of gravity (COG) to different positions along the longitudinal centerline of the aircraft or fuselage. The incremental shifting or moving of the COG from front to rear or vice versa incrementally changes the “angle of attack” of the wing, thereby producing a variable range of viable flight attitudes and resultant terminal velocities (top speeds). Therefore, users can easily select an appropriate speed for the airplane to fly in limited indoor spaces or in larger outdoor areas. Additionally, the COG shifting of the present invention can be applied not only to RC and IR controlled toy models/aircrafts but may also be implemented into real aircrafts including manned and unmanned aircraft for civilian and/or military applications.

Abstract: The invention described here offers a low-cost method of remote flight control suitable for use in toy airplanes and ornithopters (flapping-wing aircraft). To accomplish this, the aircraft is powered by a reversible electric motor. The propeller or flapping wing produces a torque force, which is dependent upon the direction of motor rotation. This torque force is used to bank the aircraft and cause a turn. In the case of an airplane, a reversible-pitch propeller enables the propeller to produce thrust in either rotational direction. In the case of an ornithopter, the torque force results from an asymmetrical motion of the wings. By reversing the motor direction, the asymmetry is reversed and the ornithopter turns in the opposite direction. This control method reduces costs, because unlike other toy aircraft control systems, it provides full directional control of the aircraft without the need for any servo or actuator in addition to the drive motor.
