20080200826 | Apparatus and Method of Diagnosing Health Using Cumulative Data Pattern Analysis Via Fast Fourier Transformation of Brain Wave Data Measured From Frontal Lobe - Provided is a health diagnosis apparatus and method in which brain waves are sequentially measured from the frontal lobe of a human body that is to be diagnosed when the eyes are in an eyes-open and eyes-closed state, the measured brain waves are fast Fourier transformed to then be accumulated, and then the health conditions of the respective portions of the human body can be determined according to the patterns with respective frequencies. The health condition diagnosis method includes measuring brain waves; performing a fast-Fourier-transform on the measured brain waves; classifying the frequency-based brain wave data into opened and closed eye state brain waves to thus accumulate the classified result; finding a specific frequency and a pattern thereof which repeats from the accumulated brain wave data; correspondingly connecting the frequency and the respective portions of the human body based on the specific frequency pattern; and determining the health condition of the human body.

20080208072 | Biopotential Waveform Data Fusion Analysis and Classification Method - Biopotential waveforms such as ERPs, EEGs, ECGs, or EMGs are classified accurately by dynamically fusing classification information from multiple electrodes, tests, or other data sources. These different data sources or “channels” are ranked at different time instants according to their respective univariate classification accuracies. Channel rankings are determined during training phase in which classification accuracy of each channel at each time-instant is determined. Classifiers are simple univariate classifiers which only require univariate parameter estimation. Using classification information, a rule is formulated to dynamically select different channels at different time-instants during the testing phase. Independent decisions of selected channels at different time instants are fused into a decision fusion vector. The resulting decision fusion vector is optimally classified using a discrete Bayes classifier. Finally, the dynamic decision fusion system provides high classification accuracies, is quite flexible in operation, and overcomes major limitations of classifiers applied currently in biopotential waveform studies and clinical applications. | 08-28-2008 |
