A system includes a computer coupled to a data storage device that stores a training data repository and a predictive model repository. A phase measurement device measures an output when an input signal having two input frequency components \u03c910 and \u03c920 is fed to an amplifier. The second movable unit carries the toner container and is configured to drag the first movable unit from the close position to the distant position. As a result, the design of the integrated circuit and part of the fabrication process thereof can be shared by a chip which is mounted in a chip size package and a chip which is mounted in another type of package. The architecture further includes multiple compute engines used to execute various packet-processing functions. The compact zoom lens has a telescopic structure of a grouped-lens sliding frame, a first cam barrel, and a linearly movable barrel underlaying a fixed barrel one over another in this order, with a second cam barrel overlaying the same.
