  • Patent number: 11722131
    Abstract: An adaptive anti-aging sensor based on a cuckoo algorithm, comprising a control module, a reference voltage-controlled oscillator, two shaping circuits, a frequency difference circuit, a resolution adjustment circuit, a 16-bit counter, a parallel-to-serial circuit, an adaptive module, and a digital-to-analog converter. A lookup table is prestored in the adaptive module; when aging monitoring is performed on a voltage-controlled oscillator in an integrated circuit, the adaptive module uses the cuckoo algorithm to determines the optimal working voltage of the currently monitored voltage-controlled oscillator, and the control module accordingly changes the input voltage of the voltage-controlled oscillator of the integrated circuit.

  • Patent number: 7109891
    Abstract: A method for arranging 37 Mandarin Phonetic Symbols (MPS) on a keypad includes arranging the 37 symbols onto 12 keys of the keypad. With this particular arrangement, a maximum number of combinations of MPS generated by pressing three keys on the keypad is reduced from 48 to 16, making input of Chinese characters considerably faster and more convenient.
