A circuit is provided that includes a first transistor having a first drain terminal, first gate terminal, and a first source terminal. An asymmetric MZI is, therefore, provided which comprises two asymmetric MIs optically connected back-to-back. A high frequency AC signal is modulated onto a positive power rail between the electrical device and the power supply. An inner wall of the nut has a plurality of tubers protruding in the axial direction to match into the opening. Thus, for participating print shops, the embodiments provide a means for increasing equipment utilization percentages during downtimes and, thereby a means to subsidize the cost of ownership.
