  • Microprocessor-based monitoring or protection device comprising an analog data acquisition system
    Patent number: 5315599
    Abstract: A certain number of high bits of each sample (12 bits) supplied by an analog-to-digital converter is used as the address of a comparison zone of a RAM associated with the microprocessor of the device. In this comparison zone the result of comparison of this sample with a predetermined number of thresholds has previously been recorded. The sample (12 bits) and associated comparison result (4 bits) are stored in a storage zone of the RAM for subsequent processing by the microprocessor. This simultaneous acquisition of a sample and of the prerecorded result of comparison of this sample with the thresholds minimizes the time devoted by the microprocessor to data acquisition.
