Quantum key distribution technologies are described that use optical homodyne detectors.
The proposed variable gap technique modifies the paralleled plate by allowing for in-situ variation of a thin specimen gap (<0.3 mm) located in a fully sealed containment inside a furnace. The gap variation is measured by a precision variance indicator.
A method of operating dual-inverter systems includes space vector selection; switching time calculation;
switching pulse placement; and deadtime compensation.
The disclosed shield includes DD coils with a different pattern and distribution of the flux density in the X, Y and Z directions: The XY-planar components are much more dominant than the Z-component.
A magnetic shield is described, the magnetic shield including patterned layers of ferrite or similar high- permeability material placed around the transmitter and receiver pad.
A flange includes a sealing hub; a mating flange; a backer ring; an inner seal; an outer seal; annular space; leak detection tubing that penetrates the mating flange between the inner and outer seals into the annular space.
A detector includes two off-the-shelf cameras that will take short stereo video clips of a building facade. The video will be analyzed using optical fluid flow detection techniques to identify the air leaking through cracks in the building.
Technologies for determining the angular position of a rotor used in a molten salt nuclear reactor are described
A method is described for suppressing voltage ringing in power converters
