Hwang is associated with 1 patent, titled “System for Finding Black Spots in a Separator from a Rechargeable Battery Cell.” The system processes a separator sample using a winder and rewinder, then removes foreign material before imaging the separator. A first camera captures an image of areas where black spots may be present and records their positions. A second camera then examines selected areas to capture images of suspected black spots and other foreign material. Deep-learning software analyzes both sets of images, and a sorting unit displays the positions of spots identified through the secondary selection process.
