An electrically variable transmission includes a power source, three differential gear sets, first and second motorgenerators each connected to at least one of the gear sets, and torque-transmitting mechanisms. The computer calculates a deflection of the ink fountain on the basis of an ink fountain model which contains forces that act on the ink fountain, and takes the calculated deflection of the ink fountain into consideration during the adjustment of the ink zone openings. The method and mechanism uses Corner Robust Current Reference in order to keep the design simple and diminish variation between Process Voltage Temperature corners. Concealed weapons are detected by measuring various parameters of the reflected signals and then calculating various selected differences between them. The ultra hard material sheet is placed over the intermediate material sheet so that the complementary faces are adjacent to each other.
