Abstract: A unitary computing device includes a rotary member and a support for supporting the rotary member and allowing a rotation of the rotary member. The unitary computing device also includes an optical disk drive and at least one orientation adjusting mechanism. The orientation adjusting mechanism includes a first linkage bar rotatably connected to the support, a second linkage bar rotatably connected to the first linkage bar and the optical disk drive, and a third linkage bar rotatably connected to the rotary member and the optical disk drive, which constitutes a linkage bar mechanism to adjust an orientation of the optical disk drive.

Abstract: A touch input device, includes a touch panel, a number of slave touch detection circuits, and a master touch detection circuit. The touch panel is divided to a number of sub-panels and each sub-panel has a reference position. Each of the slave touch detection circuits is connected to one of the sub-panels and is configured for detecting user touch of one of the sub-panels, and producing a touch signal including the touch position of the one of the sub-panels in response to the users touch. The master touch detection circuit is connected to the number of slave touch detection circuits, and is configured for receiving the touch signals from the slave touch detection circuits and determining a touch position of the touch panel according to the touch signals and the reference position of the sub-panel connected to the slave touch detection circuit producing the touch signal.

Abstract: A method for audio test of an audio test device is provided. The audio test device includes audio ports, decoders, a storage unit, and an encoder. Each of the decoders includes an identification corresponding to one of the audio ports. The storage unit stores audio files. The method includes displaying a test interface, which includes a plurality of recording the audio ports and a plurality of recording preset test items being corresponding to the audio files; obtain the IDs of the decoders and the audio files; controlling the encoders to encode the audio files and to embed the corresponding ID, and identifying the IDs of the encoded audio files and transmits the encoded audio files to the corresponding decoders according to the identified IDs. A related audio test device is also provided.
