45results about How to "Promote equalization" patented technology

In one aspect of the invention, a gain equalizer comprises a wavelength division demultiplexer operable to separate one or more communication bands into a plurality of wavelengths and an array of phase shifter stages. Each phase shifter stage comprises a micro-electro-optic system (MEMS) device comprising a moveable mirror layer operable to receive a first copy of an input signal from a beam splitter and to reflect the first copy of the input signal for combination with a second copy of the input signal at an output to form an output signal. The moveable mirror layer is displaceable in a substantially piston-like motion to introduce a phase shift between the first and second signal copies at the output, the amplitude of the output signal varying depending on the displacement of the moveable mirror layer. The gain equalizer further comprises a wavelength division multiplexer operable to receive a plurality of phase shifted wavelengths from the second beam splitter and to multiplex at least some of the phase shifted wavelengths into an optical output signal.

While powerful in diffusion at one resolution to print photos at a finer resolution, the invention is not thus limited. It defines superpixels (“spels”) for each desired colorimetric level, generates/receives image data, renders by finding levels for image positions, and prints an image using selected spels. One invention aspect finds a randomized value at each found level and uses the value to select the spel from plural ones for each level. Another aspect derives/maintains a randomized-value matrix; and maps a matrix location to an image position, to select a random value at that location and spel for that position. Another uses the value in common for all planes to select a spel for each plane at the found level—compatible spels for different planes, to coordinate color placement in planes. Another controls defining/selecting for a blue-noise property of spels in aggregate. In another, spels defined for a level vary in value to yield nonintegral color quanta. Preferences: Rendering is 1D per color, plus a dummy dimension holding the value (a least-significant bit from rendering, in a color dimension but decorrelated from levels)—and derives/maintains the matrix, derived/corrected for blue noise and including small interleaved 1D matrices tiled across and wrapped around the larger. Mapping uses values as pointers into dimensions of a spel table, and color-plane identification as a pointer into a third table dimension; it uses a common value in all planes to avoid drop-on-drop. Spels are Fourier-screened.

A method of estimating a state of an electric power distribution system that includes a plurality of nodes and at least one electrical monitoring sensor includes measuring electric current flow (I), real power flow (P), and reactive power flow (Q). The method also includes determining estimated real power load values (P_Lis) and reactive power load values (Q_Lis) and determining a plurality of estimated load current values (I_Lis) based on the P_Lis and the Q_Lis. The method further includes measuring a value of voltage (V_M) for at least one node and determining a voltage estimate (V_i) for the node. The method also includes comparing the V_i with the V_M, thereby determining a difference value between the V_i and the V_M. The method further includes determining that the difference value exceeds a threshold and adjusting the P_Lis and the Q_Lis to match the V_i and the V_M.

A large diameter conduit extends from a subsea location surrounding a wellhead to an area above the water surface. The conduit is designed to channel escaped oil and gas from the underwater well to a floating collection facility. The conduit has a portion formed from polyvinyl chloride to reduce paraffin solidification and methane gas icing.
