  • Patent number: 12194676
    Abstract: The invention discloses a multi-cell digital light processing printer and method controlled by “light field-magnetic field” coupling. The invention couples a magnetic field generating device and a light curing device, and uses the magnetic field to control the material changing of microspheres carrying different cells and different magnetic contents in the vat, so that the material changing process and the printing process are in parallel, and the printing efficiency is improved; at the same time, a single vat is used for non-contact material changing, which reduces cross-contamination and can produce multi-cell biological structures with “high accuracy, high efficiency, and high cell activity”.

  • Publication number: 20230091469
    Abstract: Disclosed is an ML attack resisting method for a strong PUF. Response signals generated by applying multiple sets of different challenge signals to a strong PUF are used as information to be encrypted, and are put in order to form a plaintext matrix. Then a matrix multiplication operation is performed on two plaintext matrixes to generate a ciphertext matrix. Next, elements in a transform matrix obtained by performing binary transformation on the ciphertext matrix are used as final responses, which are in one-to-one correspondence with original challenge signals and are used as final CRPs of the matrix-encrypted strong PUF.
