<p><P>PROBLEM TO BE SOLVED: To provide a device for determining the depth of chest compression. <P>SOLUTION: The device includes: an accelerometer capable of producing an acceleration signal of chest compressions; a processor for producing an estimated actual acceleration signal from the acceleration signal; and a means for integrating the acceleration signal, the means for integrating capable of producing an estimated actual depth signal corresponding to the estimated actual depth of chest compressions. The processor includes: a system identifier capable of producing an estimated noise signal corresponding to the noise component of the acceleration signal, wherein the system identifier produces the estimated noise signal by processing the measured acceleration and at least one error source reference; and a means for combining signals capable of combining the acceleration signal and the estimated noise signal to produce the estimated actual acceleration signal. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
