A gate-on voltageLED driving voltage generator includes an inductor boosting an input voltage through a PWM voltage and the input voltage, a diode and capacitor rectifying the boosted voltage, a first output terminal outputting the rectified voltage to supply an LED driving voltage to an LED, and a second output terminal supplying the rectified voltage to a gate driving circuit. The subscriber phone equipment includes a location test module and a datastore. The demand component includes decision analysis components for one or more demand oriented activities in the. The force applying mechanism is coupled to the first end of the yoke.
