  • Method and apparatus for electronic detection and determination
    Patent number: 11002750
    Abstract: Method and apparatus for electronic detection and determination includes detecting a signal T0 in a detection zone and a signal R0 in a reference zone before a sample is added; adding a sample and detecting the signals in each of the detection zone and the reference zone at an interval of a second preset period; calculating a judgement value based on 2k immediately previous signals in each of the detection zone and the reference zone, the signal T0 in the detection zone before the sample is added, and the signal R0 in the reference zone before the sample is added, each time when k successive signals are detected in each of the detection zone and the reference zone; and determining a judgement result based on m successive judgement values and a preset result threshold corresponding to a current detection time.
