A composition, apparatus and method of use of the composition and apparatus are described. A first FET and a power supply are connected to a primary winding of the flyback transformer. The receiving unit and the reflecting unit face each other. The adjusting mechanism includes a plurality of rotatable cam portions that engage with respective portions on the runway and landing so that each of the runway and landing may be oppositely pivoted around an end to maintain the parallel relationship. The method includes the steps of imaging a first side of the wafer, imaging a second side of the wafer, establishing correspondence between a portion of first side image and a portion of a second side image, and superimposing image data from the first and second sides to determine at least the position of a mark relative to an article. The image rendering system processes the received data in a manner that allows for rendering the original layered data without rendering each original layer separately by reordering the original layered digital image data into fewer layers.
