A trigger assembly for an electric power tool includes a switch for electrical connection to the power tool for controlling operation of the power tool, and a trigger coupled with the switch for operating the switch. The light source module is disposed at a first side of a rotary wheel of the color wheel module. Water in the misted wastewater is evaporated, thereby concentrating minerals in the wastewater. The remote agent transmits, to the local machine, window attribute data associated with the modified window and graphical data representing the window displaying the plurality of icons. Consequently, movements to and vibrations from the chassis are less likely to be transmitted to the rotary actuator assembly and, ultimately, to the HDD readwrite head. In one aspect, a method for regulating an output voltage includes receiving data indicative of a power setting associated with an identified state of an electrical circuit, the power setting based on a load current demand of the electrical circuit in the identified state, enabling one or more parallel driver segments based on the received data indicative of the power setting.
