  • Publication number: 20150193376
    Abstract: This invention discloses a multi-scales intrinsic entropy analysis method that can quantify the entropies on difference time scales for a complex time series. The implementation of the method decomposes a complex time series into a plurality of intrinsic mode functions by a nonlinear signal processing algorithm, such as the method of empirical mode decomposition. Then, the entropy increments can be calculated on multiple coarse-graining scales when an intrinsic mode functions is added into the reconstructed time series analyzed by the method of multi-scale entropy. The entropy increment is significant on a specific coarse-graining scale, which corresponds to the averaged period of the intrinsic mode functions. The entropy increment on the specific coarse-graining scale is defined as the intrinsic entropy for an intrinsic mode functions. Multiple intrinsic entropies represent the entropy properties for a complex time series on their corresponding time scales.

  • Publication number: 20150162009
    Abstract: The present invention provides an analysis system adapted for processing a signal with a time period. The analysis system comprises a segmenting unit, an analyzing unit, processing unit and an outputting unit. The segmenting unit divides the signal into a plurality of scale windows according to one of interval scales. The analyzing unit processes the scale windows via HHT algorithm to make each scale window generate a plurality of quantized windows according to different components. The processing unit reorganizes the quantized windows make each scale window generate a plurality of quantized windows according to different components. The outputting unit accumulates a plurality of specific frequency values in difference interval scales and combines the specific frequency values to form a three-dimensional variation visual diagram.

  • Patent number: 8403848
    Abstract: An assessment of sleep quality and sleep disordered breathing is determined from the cardiopulmonary coupling between two physiological data series. In an embodiment, an R-R interval series is derived from an electrocardiogram (ECG) signal. The normal beats from the R-R interval series are extracted to produce a normal-to-normal (NN) interval series. The amplitude variations in the QRS complex are used to extract to a surrogate respiration signal (i.e., ECG-derived respiration (EDR)) that is associated with the NN interval series. The two series are corrected to remove outliers, and resampled. The cross-spectral power and coherence of the two resampled signals are calculated over a plurality of coherence windows. For each coherence window, the product of the coherence and cross-spectral power is used to calculate coherent cross power. Using the appropriate thresholds for the coherent cross power, the proportion of sleep spent in CAP, non-CAP, and wake and/or REM are determined.

  • Patent number: 7882167
    Abstract: In a subject undergoing therapeutic intervention, efficacy of the therapeutic intervention is assessed based on a series of physiologic data associated with the subject. The series of physiologic data is analyzed to produce a measure of complexity. The complexity measure is then compared to a control. The efficacy of the therapeutic intervention is assessed based on the comparison of the complexity measure to the control. The control may be, for example, a complexity measure taken prior to initiation of the therapeutic intervention, a complexity measure taken from a different subject, or a predetermined threshold value. The measure of complexity is generated using, for example, a multiscale entropy measurement (MSE), a time asymmetry measurement, and/or an information-based similarity measurement. An increase in complexity indicates a positive effect of the therapeutic intervention, while a decrease in complexity indicates a negative effect of the therapeutic intervention.

  • Publication number: 20090316976
    Abstract: Provided herein are methods and systems for assessing cellular flickering. The methods include using a phase contrast microscope to obtain a plurality of images of a cell, digitizing and/or pixilating the plurality of images such that the plurality of images are segmented into an array of pixels, each pixel representing a portion of the cell, and measuring the fluctuations in the pixel intensities. The methods further include calculating a complexity measure for the individual pixels based on the measured fluctuations of the portions of the cell represented by the individual pixels. Such complexity measures can then be mapped and/or plotted in order to assess cellular flickering, and thereby assess biological function and other characteristics of the cell.
