An arrangement for efficiently shifting energy received at a first wavelength and outputting the shifted energy at a second wavelength. The method comprises coupling a first test lead to a first conductor, the first conductor at least partly isolated by the insulation system and coupling a second test lead to a second conductor or a ground. A heuristics component may additionally refine results of the coherence component and the variation component. Alternatively, the printed loop fabric may be achieved by applying a thermoplastic material to the backside of the loop fabric and printing on the thermoplastic material. The excellent device performances provide a promise for linear and large signal amplifiers and high-frequency circuit applications. Thereby, valid color pixel rate can be obtained at blocks belonging to a color region even though an image is almost monochrome but partially colored.
