Imaging devices incorporating semi-volatile NAND flash memory are described herein. This C3mux circuit includes a set of nonlinear coupling capacitors, such as metal-oxide-semiconductor transistors, that can multiplex multiple input signals while minimizing the parasitic capacitance penalty associated with the \u2018off\u2019 paths. Unlike other calcium fortified protein-containing beverages, such beverages can be produced using a process that is similar to that used to produce regular dairy milk. Besides, an upper-limit electric power of an electric motor may be reduced each time the steering operation that satisfies the steering operation criterion condition is performed.
