Abstract: A data control circuit includes an output stage circuit, a switch circuit, and an impedance module. The output stage circuit outputs a data signal. An input terminal of the switch circuit is coupled to an output terminal of the output stage circuit, and an output terminal of the switch circuit is coupled to a post-stage circuit. According to a control of a control signal, the switch circuit determines whether to transmit the data signal of the output stage circuit to the post-stage circuit. The impedance module is configured in the output stage circuit, configured between the output stage circuit and the switch circuit, or configured in the switch circuit. Here, the impedance module reduces noise flowing from the switch circuit to the output stage circuit.

Abstract: An interface circuit includes a receiver, a first terminal resistor, a second terminal resistor, a common mode capacitor, a first switch, a second switch, and a common mode potential adjustment circuit. The receiver includes a first channel for receiving a first channel voltage, and a second channel for receiving a second channel voltage. The common mode capacitor provides a common mode potential. The first switch electrically connects the first terminal resistor to the common mode capacitor, and the second switch electrically connects the second terminal resistor to the common mode capacitor. The common mode potential adjustment circuit is coupled to the first switch, the second switch and the common mode capacitor, and adjusts the common mode potential according to the first channel voltage and the second channel voltage.

Abstract: A portable storage device includes a storage module whereon a hole is formed, and at least one lateral plate disposed on a lateral side of the storage module. A slot is formed on the lateral plate. The portable storage device further includes a fixture disposed on a front side of the storage module. The fixture includes at least one wedging component for wedging in the slot of the lateral plate, and at least one groove is formed on the fixture. The portable storage device further includes a lock mechanism disposed on a side of the fixture. The lock mechanism includes at least one lock including a protrusion for protruding into the groove on the fixture, and an elastic component connected to the lock for providing an elastic force to the lock so that the protrusion wedges in the groove on the fixture.

Abstract: A disc drive holder includes a frame connected to a first side of a casing in a rotatable manner. A containing space is formed inside the frame for containing a disc drive. The disc drive holder further includes a supporting component pivoted to the frame. The supporting component includes a flexible section pivoted to the frame in a flexible manner, and a base section for supporting the frame on a second side of the casing when the flexible section is rotated out of the frame.
