Latest Patents

Stefan Johansson holds a patent for a "System and method for electric current leakage detection in a land seismic system." This invention involves generating at least one test signal using digital to analog converter (DAC) circuitry, which is connected to earth ground. The method alternates grounding a positive path to an analog to digital converter (ADC) during a first time window and a negative path during a second time window while measuring an ADC signal. By determining the average amplitude of both time windows, the system can effectively assess leakage resistance.
