Abstract: A portable integrated universal ground control system is disclosed that operates, pilots, and manages unmanned vehicles via integrated HOTAS flight controls, computer, wireless video receiving technology and a set of display screens. The portable integrated universal ground control system eliminates deep learning curves necessary to operate or pilot complex, commercial unmanned systems by offering streamlined hardware. The portable integrated universal ground control system also eliminates countless connectors, wires and work flows needed to pilot and operate unmanned systems.

Abstract: The present disclosure describes flight training systems and methods for radio-controlled (RC) airplanes that rely on inertial attitude estimates. Preferred embodiments include an RC airplane with one or more control processors configured to (i) estimate an inertial attitude of the RC airplane based on one or more measurements from an attitude sensor array and (ii) control the inertial attitude of the RC airplane based the inertial attitude estimate. In operation, controlling the attitude of the RC airplane may include both controlling the RC airplane to a specific inertial attitude and/or keeping the inertial attitude of the RC airplane within a predefined flight envelope.

Abstract: A new tray configuration for a distillation column that utilizes the entire column cross section area as active tray area for vapor/liquid contact. The new tray configuration has no downcomers and utilizes a liquid/vapor seal pan(s) located in the vapor space of the adjoining tray to collect liquid from the tray, provide entrained vapor disengaging, distribute liquid from one active tray to another and provide a liquid and vapor seal between contact trays.
