  • Patent number: 11658114
    Abstract: A fusible structure includes a metal line with different portions having different thicknesses. Thinner portions of the metal line are designed to be destructively altered at lower voltages while thicker portions of the metal line are designed to be destructively altered at lower voltages. Furthermore, one or more dummy structures are disposed proximal to the thinner portions of the metal line. In some embodiments, dummy structures are placed with sufficient proximity so as to protect against metal sputtering when metal line is destructively altered.

  • Patent number: 10572741
    Abstract: An image-based vehicle classification system includes a camera and an image server connected to the camera. The camera captures images of a road to result in an image stream. The image server includes a processor for receiving the image stream from the camera. For each of the images of the image stream, the processor performs image segmentation, a thinning process, an erosion process and a dilation process, and classifies, by a neural network classifier, a vehicle image part contained in the image into one of a large-size car class, a passenger car class and a motorcycle class when it is determined that the vehicle image is crossing an imaginary line set in advance in the image for counting vehicles.
