Latest Patents

Liu's latest patents include innovative technologies aimed at quantitatively characterizing slow wave activities and states in sleep. One of his notable inventions is a method for quantitative sleep characterization that involves acquiring a surface electroencephalogram (surf-EEG) signal from an individual. This method decomposes the surf-EEG signal into multiple intrinsic mode functions (IMFs) and calculates a ratio to identify periods of slow wave sleep (SWS) based on predetermined thresholds.

Another significant patent addresses dynamic cerebral autoregulation (CA) assessment. This method involves acquiring blood pressure and blood flow velocity signals, decomposing them into IMFs, and determining dominant oscillatory frequencies. By calculating the instantaneous phase difference between characteristic IMFs, Liu's invention can identify pathological conditions in individuals, thereby contributing to better health monitoring.
