Abstract: An interchangeable instrument panel overlay system for a flight simulator interchangeable with another simulating a different aircraft. Each instrument panel simulating a particular type of aircraft and containing switches, knobs, and/or buttons of approximately the same type and approximately the same location as in the simulated aircraft. The instrument panels capable of simulating a variety of avionics suites, gauges, and/or other equipment. The instrument panels capable of being affixed over a visual display displaying avionics suites, gauges, and/or other equipment.

Abstract: An interchangeable instrument panel, throttle quadrant, and control device (stick and/or yoke) for a flight simulation system each independently interchangeable with another simulating a different aircraft. Each instrument panel simulating a particular type of aircraft and containing switches, knobs, and/or buttons of approximately the same type and approximately the same location as in the simulated aircraft. The instrument panels capable of simulating a variety of avionics suites, gauges, and other equipment. Each throttle quadrant simulating a particular type of aircraft (e.g. single engine; multi-engine; knob/pull style; lever style).

Abstract: A motion platform providing motion for roll, pitch, heave, surge, yaw, and sway from only three electric motors. Each motor moving one of three frames in a particular direction (roll, pitch, or yaw) via either a pulley style system or a direct system. The motion platform having a control system to precisely move the motion platform in response to received commands. The motion platform capable of operating in a room with at least eight foot ceilings and one standard power outlet. The motion platform utilizing pneumatic cylinders and infrared beams as safety devices.

Abstract: A flight simulation system capable of simulating multiple aircraft through interchangeable instrument panels, throttle quadrants, and control devices (stick and/or yoke). The system has multiple visual displays capable of displaying simulated outside views and instrument displays (e.g. multiple aircraft, avionics suites, gauges, etc.). The instrument panels simulating a particular type of aircraft and containing switches, knobs, and/or buttons of approximately the same type and approximately the same location as in the simulated aircraft. The system containing a communications system compatible with standard pilot headsets and a pilot key for logging, storage, and permissions.

Abstract: A remote sensor and associated data processor, performs concurrent analysis of backscattered signals from a multi-beam (6-10) acoustic Doppler emitter/receiver (1) positioned against the inside wall of a conveying pipe (2) or channel. Range-gating of the return signals allows independent analysis of discrete volumes of backscattered signal data corresponding to the distribution, concentration and travel velocity of small individual volumes or bins of water and suspended solids (4). Velocity is derived from the measured Doppler frequency shift for each bin. Relative solids concentration is estimated as a function of the measured intensity of the backscattered signals.
