  • Publication number: 20120162884
    Abstract: A mounting apparatus for an expansion card includes a shaft fixed to the expansion card, and a rotary member rotatably mounted to the shaft. The rotary member includes a cam, an operation portion opposite to the cam, and a latching portion formed between the cam and the operation portion. When fitting the expansion card to an expansion socket, the operation portion is operated to rotate the rotary member about the shaft, and the latching portion is latched to the expansion socket. When disassembling the expansion card from the expansion socket, the cam is levered against a top of the expansion socket to lift out the expansion card, thereby disassembling the expansion card from the expansion socket.

  • Publication number: 20110181890
    Abstract: The present invention provides an imaging and measuring apparatus for the surface and the internal interface of an object, which comprises a broadband wave source, a wave-splitting structure, a wave-delaying device, a reflecting component, and a sensor. The broadband wave source transmits a broadband incident wave. The wave-splitting structure splits the broadband incident wave into a first incident beam, a second incident beam, and a third incident beam. The first incident beam is illuminated on an object under test, which reflects a measuring beam. The wave-delaying device receives the second incident beam and reflects a reference beam. The reflecting component receives the third incident beam and reflects a calibration beam. The sensor receives a first interference signal of the measuring beam and the reference beam, and a second interference signal of the reference beam and the calibration beam.

  • Publication number: 20110157779
    Abstract: An electronic device includes a chassis, a cover on the chassis, a fixing member fixed on the cover and a handling member. A pair of latches are arranged on the chassis and each define a latching hole. The fixing member includes a substrate and a pair of side plates each defining a locking groove. A pair of catches extend upwards from the substrate and each define a locking groove. Cooperatively the locking groove and the latching groove forms a closed groove. The handling member includes a pivot received in the closed groove, and a pair of shafts in the guiding grooves. Firstly, the handling member rotates around the shafts to cause the pivot to engage with the latch, and then rotates into the aperture around the pivot to cause the shafts to move upwards to make the cover moving relative to the chassis to lock with the chassis.

  • Publication number: 20110139952
    Abstract: A bracket for mounting a data storage device thereon includes a holding frame and an operating structure. The holding frame includes a substrate and first and second sidewalls extending from two opposite sides of the substrate. A receiving space is defined in the holding frame for receiving the data storage device therein. The operating structure is mounted to the first sidewall and includes an active member and a passive member connected with the active member. The active member defines a receiving groove for receiving one side of the data storage device therein. The passive member defines a sliding groove for receiving one end of the active member therein. The active member is slideable in the sliding groove of the passive member. The passive member is slideable along the first sidewall.
