A method, in a power supply controller, of responding to an increase in current through a terminal of the power supply controller, is disclosed. The control system comprises one or more sensors for temperature, moisture andor flow rate in the dryer vessel andor of the material inside, entering andor exiting the dryer vessel and a controller responsive to the sensor for controlling the fuel andor air flow into the gas turbine. The controller sets the imaging condition for a period from a start to an end of a driving of the diaphragm according to the received driving speed information of the diaphragm when the sending unit sends the control signal to the interchangeable lens. The anchor structure, the neural stimulator, the power supply and the at least one electrode are configured to be implanted through a pulmonary valve into the pulmonary artery.
