A dc electrical machine with a large number of phases. The method including: dividing a datapage into a plurality of regions; modulating the data into codewords having different on-pixel rates; and arranging the codewords in the plurality of regions, based on the different on-pixel rates. After the metal rerouting interconnect has been added to the die on the wafer, the wafer is optionally thinned and each die or multiple die segment is singulated from the wafer by cutting or other appropriate singulation method. For each team master stream, the task notifies the operating system that the team is ready to be swapped out when each other thread of the team has saved its state and has quit its stream. A method of calibrating a thickness measurement gauge and a calibration stand are also provided. The first roller and the second roller are connected with each other by a connector member, which rotatably supports the first shaft and the second shaft and maintains positional relation of the first shaft and the second shaft with respect to each other.
