    摘要: There is described a double-clad fiber coupler (DCFC) composed of two double-clad fibers that have been fused together and tapered. The DCFC allows the propagation of light in the fundamental mode in its single-mode core with very little loss. Back reflected light may be collected two ways: by the core of the double-clad fiber and by the inner cladding of the double-clad fiber.

    摘要: The present invention is based on the principle of depth of penetration of electromagnetic rays. In the case of semiconductor mono-crystalline materials, such as silicon, the depth of penetration of a light ray is proportional to its wavelength. Using this phenomenon, the present invention consists of a pixel having three electrodes that can discriminate between the colors red, green, and blue, and thereby reconstruct a color image.

    摘要: An optimization method comprising: (a) receiving a target value for power received at an antenna, (b) selecting a number of rectifier stages from a first range, and selecting a rectifier transistor drain current from a second range, (c) determining a computed value of the received power, (d) determining an input voltage at which the computed value of the received power matches the target value, (e) determining an output voltage based on the input voltage, the number of stages, and the transistor drain current, (f) when at least one additional value from the first and/or the second range remains to be selected, incrementing the number of stages and/or the transistor drain current, and repeating steps (c) to (e), and (g) when all values from the first and the second range are selected, determining a final number of stages and a final transistor drain current at which the output voltage is highest.

    摘要: A system and method of fluid delivery for providing a surface fluid pattern. The system includes a fluid delivery head for fluid flow therethrough. The fluid delivery head includes a fluid delivery surface having surface openings defined therein and arranged across the fluid delivery surface as a two-dimensional display. Some of the surface openings are grouped as a surface opening unit. The surface opening unit includes at least one aspiration opening through which fluid can be provided to the fluid delivery surface and at least one injection opening through which fluid can be moved away from the fluid delivery surface. The surface opening unit includes at least three surface openings positioned as a two-dimensional display and outwardly of at least one other surface opening.
