Abstract: An exemplary computer enclosure for detachably coupling an external device to the computer enclosure by a cable includes a receiving cavity, a interface device, and a cable guide member. The receiving cavity is configured for receiving a portion of the cable. The interface device is movably received in the receiving cavity. The interface device defines at least one port for coupling the cable thereto. The cable guide member is located adjacent to the receiving cavity, and the cable guide member supports the cable that extends from the at least one port.

Abstract: An ultrasonic test apparatus includes a container containing de-ionized water, a pressing member, a supporting member, and a fixing member. The limiting member, the loading member, and the cover member are disposed in the de-ionized water. The fixing member tightly fixes the pressing member and the supporting member together for mounting at least part of integrated circuits to be detected between the pressing member and the supporting member.

Abstract: A projector includes a main body emitting light beams from a front end to form an image, a supporting member for supporting the main body, the supporting member is pivotally mounted to a side wall of the main body, so that the main body may tilt with respect to the supporting member to obtain an adjusted position to project the image, and a fastening member fastening the supporting member on the side wall at the adjusted position. A supporting structure thereof is also provided.

Abstract: An exemplary keyboard includes a row-and-column scanning matrix and a lock switch. The row-and-column scanning matrix includes a controller including a plurality of input ports and output ports, a plurality of keys electrically connecting the plurality of input ports to the plurality of output ports of the controller via a plurality of row conductive lines and column conductive lines when actuated. The lock switch connected in series with one or more of the plurality of keys is configured for disabling the one or more of the plurality of keys when opened.
