Some embodiments of the invention provide a computer-based application that allows its users to insert their pictures in a variety of different photo books. The protection switch is controlled by means of a shutter switch, which is powered from the output of the converter and gated from the half bridge node of the converter. A refrigerant introducing passage formed in the movable scroll for introducing a refrigerant from the compression chamber to a driving mechanism. Lastly, the power management controller determines a power savings sleep voltage for a runsleep mode power management condition and controls the sleep power voltage output of the sleep regulator according to the power savings sleep voltage.
