  • Current measuring device and processing unit comprising one such device
    Patent number: 8160829
    Abstract: The current measuring device comprises a first measuring resistor to receive a measurement current, and a first signal amplifier having an input connected to said first measuring resistor and an output to provide a first measurement signal. A second measuring resistor is connected in series with said first measuring resistor, and first voltage limiting means are connected in parallel on the first measuring resistor to branch a first shunt current off when a first limiting voltage is reached on said first measuring resistor. The value of the first measuring resistor is greater than the value of the second measuring resistor A processing unit comprises one such current measuring device.
    Type: Grant

  • 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.
