Abstract

A ballistocardiogram (BCG) analysis apparatus, method, and system is provided for utilizing the BCG for a vehicle. A basic pattern is selected when measurement of a BCG is initiated. Data about BCG is measured for a predetermined period of time. Whether the basic pattern is suitable for the measured data is determined by comparing the measured data with the basic pattern. If the basic pattern is suitable for the measured BCG data, continuous data about the BCG is collected. Signal processing is performed based on pattern matching using the continuous data. A biological condition of the examinee is recognized using results of the signal processing. A posture of the examinee is measured, and if the posture of the examinee has changed, a pattern DB is searched, the basic pattern is changed to a suitable pattern, and then signal processing is performed.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0135569 filed on December 15, 2011, the entire contents of which are incorporated herein by reference for all purposes. technical field [0003] The present invention relates to the technique of measuring and analyzing a passenger's ballistocardiogram, and then using the ballistocardiogram to perform subsequent actions, such as performing ventilation or massaging a passenger. Background technique [0004] Ballistocardiography (BCG) involves measuring the body's reaction to the heart's ejection, which then enables the state of the heart to be estimated. The principle of measurement is to obtain the BCG signal by measuring small changes in blood acceleration or changes in body weight according to the counterforce of cardiac ejection. [0005] figure 1 The principle of conventional BCG measurement is shown. That is, a sensor capable of measurin...
