The present invention provides a computer-implemented method, system, tool, and program product for sending a customized reply to an instant message. If the net total power is a net supply power, the EMS causes regenerative power to be provided to a power source and energy source in a controlled manner to initially charge the power source to a desired state-of-charge and then subsequently charge the energy source. A lower IMP film is formed at a high AC bias power followed by the formation of an upper IMP film at a lower AC bias power. When the input voltage is normal but the front-stage power circuit is disabled, the auxiliary switching circuit is turned off under control of the controlling unit, so that electric energy of the input voltage is transmitted to an input terminal of the standby power circuit through the protecting circuit. Conversion of the pixel values is then performed by reference to the lower and upper limit values. A preferred salt is 1-4-butyl-4–piperazine hydrochloride.
