  • Patent number: 11323299
    Abstract: A communication signal demodulation apparatus demodulates a communication signal to generate an output signal. The communication signal demodulation apparatus includes: plural sensor circuits which sense different electrical characteristics of one same communication signal and generate corresponding sensing modulation signals respectively; plural processing filters which filter the corresponding sensing modulation signals respectively and generate corresponding filtered modulation signals respectively; plural demodulators which demodulate the plural filtered modulation signals and generate corresponding demodulation signals respectively, wherein each of the filtered modulation signals corresponds to at least one of the demodulators; and a determination circuit which receive the plural demodulation signals, determine whether each unit signal of each of the demodulation signals is correct or not according to a determination mechanism, and combine one or more correct unit signals to generate the output signal.

  • Patent number: 8341446
    Abstract: By classifying an electro-phoretic display integrated circuit (EPD IC) into a digital routine module, a digital non-routine module, and an analog routine module, and by switching off the digital non-routine module and the analog routine module, power consumption of the EPD IC may be effectively reduced, and an available time of an integrated circuit card utilizing the EPD IC may also be lengthened.
