  • Patent number: 11114060
    Abstract: A cursor image detection comparison and feedback status determination method is disclosed. The method is based on a non-invasive data-extraction system architecture, and uses an image processing unit to perform detection comparison on a cursor image shown on an operation screen outputted from a machine controller. The method includes steps of obtaining cursor foreground and background images set by a user, and selecting an algorithm to process the cursor foreground and background images to generate a cursor mask, and reading a cursor image and applying the cursor mask on the cursor image for pattern comparison, transmitting information of a comparison result and a cursor feedback status to a software control system, so as to provide a correction system to perform a cursor process program and check whether the movement of the cursor meet a position controlled by a feedback and correction system, thereby completing closed-loop control for the cursor.

  • Patent number: 9504357
    Abstract: An insulating pot bottom for stockpots has a connecting base, a flame guiding block, and multiple insulating mounts. The connecting base has a bottom panel, an inlet hole, and multiple abutting ribs. The inlet hole is formed through the bottom panel. The abutting ribs are formed on and protrude from the bottom panel at spaced intervals around the inlet hole, and each one of the abutting ribs has at least one protrusion. The flame guiding block is mounted in the inlet hole of the connecting base and abuts the protrusions of the abutting ribs. The insulating mounts are mounted on the connecting base, and respectively abut the abutting ribs around the flame guiding block.

  • Publication number: 20090225524
    Abstract: A method for forming a via hole in a hollowed PCB, which has a hollow portion and at least one insulating layer, includes the steps of: providing a lining pad on a first surface of the insulating layer that is adjacent to the hollow portion; drilling the via hole in the insulating layer from a second surface of the insulating layer that is opposite to the first surface of the insulating layer. In such a way, when the insulating layer is drilled to form the via hole, the insulating layer is supported by the lining pad, thereby preventing the defects, such as burrs, cracks, or pads, from occurring.
