A system, method and computer-readable medium are disclosed for identifying representative data using sketches. An incoherent fiberoptic bundle maps a line illumination pattern into a dispersible group of separate sources, and then remaps this confocally selected remitted light to the original line. The emitter electrode has a plurality of pins axially arranged about a center. A first sensor is mounted adjacent to the display element. Moreover, because no ICs are required in the whole circuit, the cost is lower. Additionally the new cultivar flowers under long day conditions and produces many lateral branches, without pinching or chemical growth regulators.
