摘要： A system is described for rapidly and accurately determining the topography of land masses as well as individual x,y,z coordinates of discrete targets. The system incorporates a laser altimeter, a laser scanning/steering system with sensor for receiving reflected laser beams, a global positioning system or other non-ground-based reference means, a video camera, computers, and processing software. The system, mounted to an aircraft, selectively scans or steers a pulsed laser altimeter over a swath or point on earth. A Global Positioning System (GPS) or other non-ground-based reference means records the aircraft's position, altitude, and time of position. Concurrently, a computer system records and time tags the laser's range, scanner angles, and airborne platform's roll, pitch, and heading. The processing software correlates all events and measurements using time to determine precise x,y,z coordinates of the ground/targets. Finally, the system post processes the combined data to produce significant terrain, vegetation, and cultural data.

摘要： An apparatus and method for determining, in real time, the key parameters of a three phase system electrical generator's output. A pair of reference vectors in quadrature (orthogonal) is phase-locked to a selected input open delta line to line voltage vector. Preferably, the cosine reference vector is locked 45° out of phase from the selected input vector whereby a best projection of the input vector onto the quadrature pair is provided and increases accuracy in subsequent magnitude and phase calculations. The phase-locked reference vectors provide a basis for computing the magnitude and phase angle for the remaining open delta line to line voltage vectors and three line to neutral current vectors. Instantaneous measurement of magnitude and phase angle for the three line to line voltages and three line to neutral currents, the generator's real power (watts), volt-amperes reactive (VARS), apparent power (VA), power factor (PF) and, as a result of the phase locking, the precise frequency of the generator are possible.
