Abstract: A method of scanning a light beam is disclosed. The method comprises scanning the light beam along a first axis and scanning the light beam along a second axis, such that a functional dependence of the scanning along the first axis is substantially a step-wave, and a functional dependence of the scanning along the second axis is other than a step-wave.

Abstract: An in-flight hose-and-drogue refueling system has the capability of steering the drogue using four thrusters which are energized by pressurized air. The system measures the drogue's 3-dimensional position relative to either the refueling aircraft or the probe on the receiver aircraft. A control system utilizes the measurements of the drogue's 3-dimensional position to activate the thrusters so as to either minimize the excursions of the drogue due to turbulence, thus enabling easier hook-up, or alternatively, to track the receiver's probe and automatically guide and contact the drogue to the probe.
