In one embodiment, a two- or dual-sided thermal print switch is provided to direct printing of received print data on one or both sides of thermal media such as a receipt, document, or label. In certain example embodiments, the vehicle grille includes adjustable louvers. The body section 2 and the movable section 3 are connected to be relatively pivoted at least between a posture in which the capsule insertion hole 6 is exposed, and a posture in which the capsule insertion hole 6 is hid by the body section 2. The system also can include a selective power management module coupled to the computer and configured to selectively apply power management to only one of the displays in which a period of inactivity is detected, while not applying power management to remaining ones of the displays. The pole includes a bottom half having a downwardly facing axial recess. In this case, the operating speed characteristic can be secured even under the low power supply environment without decreasing the threshold voltage of the transistor.
