  • Heat dissipation module
    Patent number: 11379021
    Abstract: A heat dissipation module suitable for an electronic device is provided. The electronic device has a heat source. The heat dissipation module includes an evaporator and a pipe assembly. An internal space of the evaporator is divided into a first space and a second space, and the heat source is thermally contacted with the second space. The pipe assembly is connected to the evaporator to form a loop. A working fluid is filled in the loop.

    Abstract: A target image of a target circuit board and a gold image of a gold circuit board are taken by an image acquisition system. Fiducial points are located on the target image and on the gold image. Perspective transformation is performed on the target image using the fiducial points on the target image for reference and on the gold image using the fiducial points on the gold image for reference. After perspective transformation, an anomalous section of the target image is identified by identifying pixels that have different intensities between the target image and the gold image, the anomalous section being indicative of an unauthorized modification to the target circuit board.
