  • Patent number: 12244740
    Abstract: An IC for adaptive PUF stabilization process includes a PUF stabilizer and a non-volatile memory. The PUF stabilizer has PUF units, a statistic processor, a majority voting generator, and a dark-bit masker. The statistic processor is connected to the PUF units, and performs measurements on the PUF units to output results. The majority voting generator is connected to the statistic processor to accumulate the results into a statistic result, which is output as a PUF bit. The dark-bit masker is connected to the PUF units, and marks unstable PUF units bit as dark-bit and create dark-bit masks. The non-volatile memory is connected to the PUF stabilizer to store the dark-bit masks, and the dark-bits are replaced by specific bit sequences provided by the PUF stabilizer. This decreases bit error rates of the PUF measurement results, and allows customization of the quantity of dark bits per dark-bit mask used.

  • Patent number: 12149641
    Abstract: A triggerable circuitry for a Physically Unclonable Function (PUF) source and true random number generator comprises an array of metastable latches PUF cells units that produce output states in racing configuration dependent on manufacturing variations and noise fed into a counting circuit. The technology as a single circuit extracts detected random bits' states for true random numbers generation, different each time when requested, and is able to feed a PUF recovery system that will use the fairly static bits' patterns of the measured circuit although each time different.

  • Publication number: 20240206370
    Abstract: An automatic precise pneumatic plug tray seedling device comprises a body, a plug tray platform, a seed groove, an air pressure source, a control device, a conveyor device, a soil punching device, and a seed device. To become an automatic control of a closed loop of a pneumatic cylinder, it adjusts the input control signals through the track positioning control in the control device and the feedback signal conveyed by the conveyor device.
