Latest Patents

Li is associated with 1 patent: “Pipeline Leakage Monitoring Method and System Based on Optical Fiber Sensing.” The invention describes a method for processing sensor signals to monitor pipeline leakage. It uses a dichotomy-based search to locate positions in sorted moving-window data, helping reduce signal-baseline jumps and drift while speeding up processing. It also adjusts the integration starting point in real time to limit cumulative effects while retaining the sensor’s low-frequency response. By mapping original data to leakage parameters, the method reduces redundant data after preprocessing.
