ORGANISM CONDITION ANALYZER, COMPUTER PROGRAM, AND RECORDING MEDIUM

WIPO Patent Application WO/2010/021227

A1

A significant biometric signal can be detected without giving a feeling of strangeness, and the condition of a person can be correctly analyzed. An organism condition analyzer includes a second-order differentiating means (61) for twice differentiating time-series signal data about an air pressure variation detected by an air cushion.  The second-order differentiation waveform obtained by the second-order differentiating means (61) is processed to analyze the condition of a person.  The time series signal data represents the pulse of an aorta in the back of the person, and the second-order differentiation emphasizes the variation of the waveform of the time-series signal data.  Information representing the organism condition included in the waveform obtained by the second-order differentiation is more significant than that representing the organism condition included in the waveform before the second-order differentiation.  Therefore, analysis of the time-series waveform obtained by the second-order differentiation bring about more accurate result of the analysis than that by conventional means for analyzing the organism condition by using the pulse of the aorta.
