Abstract: A kite assembly and method of flying a kite from a wind source such as a fan, generally indoors, incorporating multiple tethers to provide generally stable, controlled and sustainable flight. The kite assembly provides for multiple tethers set to appropriate lengths and tethered to appropriate places on the kite and the wind source. Multiple tethers help balance the kite and prevent the kite from flying out of the lifting zone of the airflow created by the wind source, when the wind source is stationary, rotated, oscillating or being moved around a room. The tethers generally diverge from the kite and as a result the kite flying characteristics or direction of flight can be controlled in ways not possible with traditionally tethered kites, which typically have single or converging tethers. Multiple kites may be flown from one fan, or connected to one another to form unique flying combinations.

Abstract: The disclosed invention consists of several improvements to well known Quad Tilt-Rotor (QTR) aircraft. The first is that during a wing-borne flight, one pair of tilt-rotors, which can be substantially larger than the other pair, is feathered and stopped. This can promote vehicle aerodynamic efficiency and can be utilized to increase vehicle speed. Second is that the wings are not attached to the fuselage at a fixed angle of incidence like on conventional QTR aircraft, but can also be tilted in respect to the fuselage independently of the tilt-rotors. Furthermore, each rotor and each wing can be tilted with respect to fuselage to any tilt-angle without limit, which gives the vehicle unprecedented ability to position the fuselage in any attitude in respect to the vehicle direction of flight.

Abstract: Methods for determining the locations/heights of fractures in a subterranean formation use a post-fracture log obtained with a compensated neutron or pulsed neutron logging tool. Utilizing predetermined relationships between tool count rates and associated near/far count rate ratios, the methods detect the presence of proppant containing high thermal neutron capture cross-section material, substantially eliminating proppant determination uncertainty resulting from changes in formation hydrogen index. In an interval of a well with given borehole and formation conditions, and not containing proppant, a relationship is developed between detector count rate and near/far ratio. This relationship is used to compute count rate from the ratio in intervals of the well possibly containing proppant and which have similar formation and borehole conditions.
