The present invention generally relates to a digital scanner for scanning images. The intercooler comprises an elongated body having a longitudinal axis. A third inverter couples a second input to the common output using a second voltage controlled pass gate. The method also comprises maintaining the second transmission mode for a predetermined time period regardless of a second change command from the first network to increase at least one of transmission power level and data rate of the user equipment. Staged systems may employ a first stage bypass to achieve a target quality with increased yield.
