  • Publication number: 20240151743
    Abstract: The present disclosure is directed to a method of manufacturing one or more needles of a probe card by refining and processing a conductive body that extends from the probe card to form a respective tip at the end of the respective conductive body. Forming the respective tip of a respective needle includes removing respective portions from the end of the conductive body by flowing an electrolytic fluid between a conductive pattern structure and an end of the respective conductive body. Removing the respective portions with the flow of the electrons may be performed in multiple successive steps to form various needles with various sizes, shapes, and profiles (e.g., cylindrical, rectangular, triangular, trapezoidal, etc.).

  • Patent number: 11966628
    Abstract: A memory device, includes a memory array for storing a plurality of vector data each of which has an MSB vector and a LSB vector. The memory array includes a plurality of memory units each of which has a first bit and a second bit. The first bit is used to store the MSB vector of each vector data, the second bit is used to store the LSB vector of each vector data. A bit line corresponding to each vector data executes one time of bit-line-setup, and reads the MSB vector and the LSB vector of each vector data according to the bit line. The threshold voltage distribution of each memory unit is divided into N states, where N is a positive integer and N is less than 2 to the power of 2, and the effective bit number stored by each memory unit is less than 2.

  • Patent number: 11798292
    Abstract: A driving assistant method applied to a first moving vehicle is provided. The method includes capturing an image of a license plate of a second moving vehicle when the first moving vehicle is moving, and identifying a first area of the license plate in the captured image. Basic information of the second moving vehicle are obtained according to a size of the first area. Once a safe distance is determined according to driving information of the first moving vehicle and the basic information of the second moving vehicle, a warning message is transmitted when the distance between the first moving vehicle and the second moving vehicle is less than the safe distance.
