A fan housing includes a first frame and a second frame. The first frame includes a clip member protruding toward the second frame, and a limit member connected with the clip member. The limit member has a slot along the outer wall of the first frame so that a wire can pass through the slot. The second frame includes an engaging member corresponding to the clip member and having a recess to be engaged with the clip member. When the first and second frames are combined, the wire will be securely fastened in the slot.
Abstract:
A ventilation apparatus with a two-section feedback compensation control and a method for operating the same are disclosed. The ventilation apparatus includes a power conversion unit, a driven circuit, a DC motor, a current-sensing unit, a voltage compensation unit, and a control unit. The power conversion unit receives and converts an AC power voltage into a DC power voltage. The driven circuit receives the DC power voltage and outputs a driven voltage. The DC motor is driven through the driven voltage. The current-sensing unit senses an output current of the DC motor. The control unit receives the output current to compare to a threshold current value, thus controlling the voltage compensation unit. Accordingly, the DC power voltage is adjusted to adjust the speed of the DC motor.
Abstract:
An electronic device and a method enable capturing a 360° panoramic image by a digital camera having a fixed angle lens. A number of frames is set for capturing the 360° panoramic image of the digital camera unit. The electronic device receives an initial azimuth of the digital camera unit from an electronic compass and determines rotation points of the digital camera unit. A current azimuth from an electronic compass of the electronic device is received and the rotated angle of the digital camera unit is calculated. The electronic device captures at least one image if the digital camera unit rotates to one of the rotation points.
Abstract:
