Additionally, a following motor torque is calculated for following the target vehicle speed based on the calculated speed difference and then is added to the distributed motor torque. No emulation of down link information frames occurs. The second photoresist-coated wafer is placed on the temperature-regulated mass and thermally equilibrated to the same temperature that the first photoresist-coated wafer had been equilibrated to.
