Abstract: A voltage measuring apparatus electrically connected to buck circuits includes the same number of RC circuits as there are buck circuits, an analog/digital (A/D) convertor, a controller, and a display unit. Each RC circuit is configured to be electrically connected in parallel with an inductor of one corresponding buck circuit. The A/D convertor selectively obtains an analog voltage of one of the buck circuits, and converts the analog voltage signal into a digital voltage signal. The controller controls the A/D convertor and receives the digital voltage signal from the A/D convertor. The display unit displays a decimal voltage value based on the digital voltage signal.

Abstract: A control circuit includes a power controller, a comparator, and first to fifth electronic switches. When an electronic device is operating with light load, a voltage received by the inverting terminal of the comparator is less than a voltage received by the non-inverting terminal of the comparator, such that the first and fourth electronic switches are turned on, and the second, third, and fifth electronic switches are turned off. A first power supply is output to the switching power supply. When the electronic device is operating with heavy load, the voltage received by the inverting terminal of the comparator is greater than the voltage received by the non-inverting terminal of the comparator, such that the first and fourth electronic switches are turned off, and the second, third, and fifth electronic switches are turned on. A second power supply is output to the switching power supply.

The driving mechanism is manipulated to operate the first latch mechanism to engage with a first edge of the chassis, and drive the second latch mechanism to engage with a second edge of the chassis.

Abstract: A fixing device includes a frame, a positioning member, and a fixing member. A first side end of a expansion card is fixed to a first side of the frame. The positioning member is mounted to a second side of the frame opposite to the first side and capable of sliding toward the first side of the frame. A number of cutouts are longitudinally defined in the second side of the frame. A receiving space is defined in a side of the positioning member for fixing a second end of the expansion card. The fixing member is mounted to the positioning member and selectively fixed to a corresponding cutout of the frame.

Abstract: An exemplary holder for a hard disk drive includes a mounting frame and a handle. The mounting frame includes a first mounting arm, a second mounting arm, a connecting arm, and a clipping assembly. One end of the handle is pivotally connected with one end of the connecting arm. The clipping assembly is attached at another end of the connecting arm. The clipping assembly includes a base, a button, a elastic member and a sliding member.
