摘要:
A flexible support apparatus, such as a tripod, supporting an electronic device, such as a personal video player. The flexible tripod may include ball and socket joint connectors which, when interconnected, form a flexible assembly. The flexible support apparatus allows the user to view the device in a variety of locations with enhanced ease, comfort, and allows for a variety of viewing angles.

摘要:
An aerial vehicle adapted for vertical takeoff and landing using the same set of engines for takeoff and landing as well as for forward flight. An aerial vehicle which uses a rotating platform of engines in fixed relationship to each other and which rotates relative to the main body of the vehicle for takeoff and landing. An aerial vehicle which is adapted to takeoff with the wings in a vertical as opposed to horizontal flight attitude which takes off in this vertical attitude and then transitions to a horizontal flight path. An aerial vehicle which controls the attitude of the vehicle during takeoff and landing by alternating the thrust of engines, which are separated in at least two dimensions relative to the horizontal during takeoff, and which may also control regular flight in some aspects by the use of differential thrust of the engines.
摘要:
An airborne centrifugally stiffened and cyclically controlled system which uses airfoils which rotate around a central hub, similar to the mechanics of an autogyro. The airfoils may achieve speeds significantly above the wind speed feeding the system. The airfoils may be linked to the central hub by flexible radial tethers which stiffen considerably as the speed of the airfoil increases, or may be linked to the central hub by rigid radial links. The central hub may be linked to the ground with an extendible main tether. Power generation turbines may reside on the airfoils and utilize the high apparent wind speed for power generation. The generated power may travel down the radial tethers and across a rotating power conduit to the main tether and to the ground. The system may use autorotation, similar to the mechanics of an autogyro. Power generation turbines may reside on the blades and utilize the high apparent wind speed for power generation with little or no need for gearing between the generator blades and the generator.
