An AC voltage regulator able to provide a desired voltage to any type of a given load within a predetermined range without any output power interruptions during any transition time, without distortion of the AC sine wave and without high current circulating through the circuit components during the voltage switching. The wireless terminal can provide identifying indicia which can be relayed to a AAA server by way of a base station. A handle is pivotally attached to the rear end of the housing body, pressing down the handle stores energy in a power spring by bending the middle section of the power spring, and further pressing down the handle unlocks the front end of the power spring which forces a driving blade to move downward and expels a staple out of the bottom of the housing body. The manifest file is generated at one computer in the replica set. At least one of the outer wall portion and the base wall portion has a plurality of elongated bumps protruding into the channel.
