A voltage regulator and a control method thereof are provided to dynamically adjust an output voltage. The voltage regulator comprises a plurality of switching transistors and a control circuit. The first end of each switching transistor receives a driving voltage, and the second end of each switching transistor is electrically connected to the end which outputs the output voltage. The input end and the feedback end of the control circuit respectively receive a reference voltage and the output voltage. A plurality of output ends of the control circuit are electrically connected to the control ends of the switching transistors respectively. Switching transistors adjust the output voltage. The control circuit compares the output voltage with the reference voltage, and selectively turns the switching transistors on or off according to the comparison between the output voltage and the reference voltage, to control the output voltage to approach the reference voltage.

The disclosure provides a cleaning apparatus and detecting method thereof. The cleaning apparatus includes a fan, a motor, a detecting device and a control unit. The motor drives the fan to create an air flow through the cleaning apparatus. The detecting device is electrically connected to the motor, and is utilized detected an impedance of the motor. The control unit is electrically connected to the motor and the detecting device respectively, for comparing the impedance of the motor with a predetermined value and outputting a signal indicative of a comparison result.

Cleaning apparatus and detecting method thereof

A method for controlling a cleaning device is presented, which includes the following steps. A cleaning device includes a control unit, a fan module, an optical emitter, and an optical sensor. The optical emitter and the optical sensor are located in an air inlet of the fan module. The control unit is preset with a first impedance value (Z1), a second impedance value (Z2), and a threshold, where 0&#x3c;Z1&#x3c;Z2. Then, the control unit reads an impedance value (Z) of the fan module. If Z1&#x3c;Z&#x3c;Z2, the control unit drives the fan module. If Z2&#x3c;Z, the control unit reads a detected value of the optical sensor. If the detected value exceeds the threshold, the control unit drives the fan module, so as to increase a suction force of the fan module. If the detected value is smaller than the threshold, the control unit turns off the fan module.

Method for controlling cleaning device

An intelligent air-condition system that detects the signals of the temperature distribution among the environment by using the infrared radiation, especially detects the location of the human-body temperature signals. Hence, according to the detected signals, the gas(es) for air-conditions can be firstly transmitted into the location where the human-body temperature signals exist, or be firstly transmitted into where the local temperature is urgent to be adjusted. Besides, the transitions of the gas(es) can be paused or stopped while there is no human-body temperature.
