Disclosed is a compound represented by Formula or a pharmaceutically acceptable salt, enantiomer or diastereomer thereof. The method includes, generating a control signal according to a regulating signal inversely proportional to the output voltage of the voltage converting circuit. Embodiments of the method may include determining whether device drivers for an operating system image source need to be updated, such as by crawling a vendor website. When the CPU receive the compare signal, if the compare signal is greater than a predetermined value, the CPU generate a first control signal to the driving device to bid the driving device lower the rate of the carry device. When the latch circuitry is disabled, the latch circuitry acts as a passive data path. A wave piercing cowling is rotatively attached to the lower section.
