A computer readable storage medium has a sequence of instructions stored thereon, which, when executed by a processor, causes the processor to acquire a plurality of actual train speed measurements from at least one sensor during a journey and acquire a train power parameter corresponding to each of the plurality of actual train speed measurements. In this method, a dielectric layer is spun over a substrate, and then an electron-beam exposure process is performed on the dielectric layer to define an exposed area and an unexposed area thereon. In one arrangement, the releasable material is disposed behind the tissue cleanser. The data drive IC including the dynamic circuit has reduced chip area and reduced power consumption.
