  • Patent number: 11948820
    Abstract: The present invention provides a latching guide structure arranged inside a door of semiconductor carrier. The latching guide structure comprises an upper latching part, a lower latching part, at least one elastic unit and a driver. Moreover, a first guiding portion of the upper latching part is matched with a second guiding portion of the lower latching part, therefore to define the installation space for the at least one elastic unit. On the other hand, the driver simultaneously actuates an upper actuating unit of the first guiding portion and a lower actuating unit of the second guiding portion to linearly move in reverse direction therebetween. The range of the linear motion of the upper actuating unit and the lower actuating unit represents the compression or extension of the at least one elastic unit, determining to control the open/close status of the upper latching part and the lower latching part.

  • Patent number: 11922044
    Abstract: A solution for deteriorated non-volatile memory is shown. When a controller determines that raw data read from the non-volatile memory is undesirable data, the controller performs safety moving of valid data of an erasure unit that contains the raw data to safely move the valid data of the erasure unit, wherein the erasure unit is a high-risk block, and the raw data in the non-volatile memory is regarded as being in a deteriorated physical address. Prior to being moved in the safety moving, the raw data is changed so that it is different from the undesirable data. In an exemplary embodiment, the undesirable data is all-1's data or all-0's data.

  • Publication number: 20230168208
    Abstract: A surface inspection system for foil article is disclosed. The surface inspection system comprises a box having a top long narrow opening and a bottom long narrow opening, a bridge interface, a first light source, a second light source, a first modular camera device having a first camera, and a second modular camera device having a second camera. In which, the first light source, the second light source, the first modular camera device, and the second modular camera device all accommodated in the box, and are coupled to a control box through the bridge interface. Particularly, this surface inspection system is allowed to be integrated in an automatic production line of a foil article like electro-forming aluminum foil (also called electronic aluminum foil), so as to achieve an in-line inspection of the surface morphology of the electro-forming aluminum foil.

  • Publication number: 20230117656
    Abstract: A defect inspection system is disclosed, and comprises a linear light source, N number of cameras, a display device, a tag reader, and a modular electronic device, in which the linear light source, the cameras and the modular electronic device are used for conducting a defect inspection of an article. On the other hand, the display device, the tag reader and the modular electronic device are adopted for conducting in production of at least one labeled example. Therefore, the modular electronic device is allowed to apply a machine learning process to an image classifier under using a training dataset containing the labeled examples, thereby producing at least one new defect recognition model or updating the existing defect recognition model.

  • Publication number: 20230061439
    Abstract: A motor controlling system is disclosed. The motor controlling system is integrated in an apparatus having roll-to-roll mechanism, and comprises a linear light source, N number of cameras and a modular electronic device. When a roll of continuous web material is discharged by an unwinding unit of the roll-to-roll mechanism so as to be further transferred to an inspection unit, the cameras are controlled by the modular electronic device to capture a plurality of time-consecutive material image frames. Subsequently, the modular electronic device conducts a defection inspection for a segment of the continuous web material by applying an image process to the material image frames. As a result, in case of there being at least one defect found, the modular electronic device stops a plurality of motors of the apparatus from running, thereby making the segment of the continuous web material be positioned on an inspection platform.
