A test device includes a power compensation module and a test module. The power compensation module receives AC power generated by a device under test to generate DC power to the device under test. The test module provides a plurality of test signals and a test mode to the device under test for testing the device under test.

Test device

A connector assembly for connecting an upper circuit board to a lower circuit board is disclosed. The upper circuit board includes a series of fastener holes for a fastening device allowing attachment to the lower circuit board. The connector assembly has a support bracket with access holes aligned with the holes of the upper circuit board. The support bracket is configurable to be positioned over the upper circuit board. The connector assembly has a moveable cover bracket having a series of access holes. The cover bracket is suspended between the support bracket and the cover bracket. The cover bracket is moveable between an open position aligning the access holes with the access holes of the support bracket, and a closed position. In the closed position, the cover bracket blocks access between the access holes of the support bracket and the holes of the upper circuit board.

A power supply includes a transformer winding, a switching circuit, a controller and a filter circuit. The transformer winding is configured to provide a first voltage. The switching circuit is coupled to the transformer winding and includes a first and a second switching unit. On the condition that the power supply is operated under a standby mode, the controller controls the first and the second switching units to provide a discharging path between two terminals of the transformer winding. On the condition that the power supply is operated under an operating mode, the controller controls the switching circuit such that the switching circuit provides a second voltage according to the first voltage. The filter circuit is coupled to the switching circuit and configured to filter the second voltage to provide an output voltage.

Power supply and residual voltage discharging method

A retention apparatus is provided for securing a cable into a receptacle of an electronic device. The retention apparatus includes a body with two distal ends. A buckle is located at one distal end while a housing is located at the opposite distal end. The buckle includes at least one tooth. The housing includes a receiver configured to secure the buckle and a handle portion. The receiver includes a securing element and guide. The securing element includes at least one notch to interconnect with the at least one tooth of the buckle.

Power cord retention device

A hot swappable fan module includes an outer frame, a cooling fan, a fixing element, and a light guide assembly. The cooling fan is located on one side of the outer frame. The fixing element is operable to fix the outer frame and the cooling fan. The light guide assembly includes a light guide post, a first stopping portion, and a second stopping portion. The light guide post penetrates through the cooling fan and the outer frame. The first stopping portion is located on the light guide post, and abuts against one surface of the cooling fan opposite to the outer frame. The second stopping portion is arranged opposite to the first stopping portion, is light-transmittable, and is optically coupled to the light guide post, and abuts against one surface of the outer frame opposite to the cooling fan.

Computer device and hot swappable fan module thereof

A power supply device includes a voltage converting circuit and a mode switching circuit. The voltage converting circuit is configured to receive a first voltage and convert the first voltage to a second voltage. The mode switching circuit is configured to provide an output voltage and an output current to a load according to the second voltage. The mode switching circuit includes a switch configured to maintain on or off on the condition that the power supply device is operated under a constant voltage output mode such that the value of the output voltage corresponds to the second voltage, and the switch is configured to switch between on and off on the condition that the power supply device is operated under a constant current output mode such that the output current of the mode switching circuit is a constant value.
