Upon forming a mosaic image by combining a plurality of material images, an original image of the mosaic image is segmented into MN areas. The power converter can receive power from the power source and provide a regulated power to the light source. The broadcasting data includes tuning information that enables receivers to tune in one or more terrestrial broadcasts transmitted by the one or more broadcasting stations. A second individual microcode controlled state machine applies a second rule to the input data to determine second instructions associated with a second subset of the input data based on second sampling information associated with the second rule. The magnet is configured at least as a segment of an annular magnet that is arranged at a second end of the lever and integrated therein. Accordingly, both communication apparatuses can differentiate the first multi-carrier signal SS from the second multi-carrier signal RS without performing relatively cumbersome modulation and other processes.
