  • Publication number: 20120019586
    Abstract: Disclosed are an automatic printing output inspection device for optic disc and a printer and a disc writer incorporating the device. The automatic inspection device includes an image taking unit that takes an image of printing output of an optic disc, which is then processed by an image processing unit and compared by a comparison and identification unit with an original source of patterns to determine printing quality of the image. When it is determined that the printing quality does not match the original source, an alarm and feed-back unit is actuated to issue alarm notification for facilitating subsequent handling. Through the automatic inspection, printing quality of an optic disc can be efficiently inspected and products with poor printing can be identified for timely notification that helps saving waste of material, improving efficiency of printing output of optic disc, and saving human labor and time for inspection.

  • Publication number: 20110225654
    Abstract: The present invention is a write-proof protection method of a storage device. The storage device includes a buffer to store data temporarily, with a capacity of the buffer being adjustable; and a write-proof control unit. The write-proof protection method includes transmitting a write-in protection signal to the write-proof control unit from an operating unit; the write-proof control unit writing a file that is written into a computer into the buffer of the storage device, rather than a file system. When a stand-alone write-proof condition has been set by a user, an unknown program that has been written in can be a virus pattern, and the unknown program in the buffer can be analyzed to discover a new virus early, so as to achieve an antivirus effect.

  • Patent number: 6836406
    Abstract: Disclosed is an automated disk-ejection apparatus for use in a disk system. The disk system includes a disk box for housing a disk drive, and the auto-ejection apparatus comprises: a handle for pulling out or pushing back the disk box; a pushing mechanism for pushing the handle; and a control circuit for controlling the pushing mechanism. The featured disk apparatus is designed such that while the disk box needs to be pulled out in order for loading or replacing the disk drive, the pushing mechanism is activated to push the handle. The handle can thus be rotated along the pivot into an inoperative state, for subsequently to be pulled for withdrawing the disk box. Moreover, another embodiment of the present invention relates to using a pushing mechanism to push a rotatable panel of a disk box.
