Filed: 2002-06-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a pulsation times calculating method for obtaining correct pulsation times from biological information even in the existence of noise due to external cause.  <P>SOLUTION: This method includes: a first process for expressing pulsation signals through the use of frequency distributions indicating a signal strength with respect to a frequency when the pulsation signals for a time unit including periodically generated pulsation are obtained, and converting each frequency distribution into a first relation expressed by elapsed time; a second process for taking out from the first relation a second relation wherein the signal strength corresponding to an intrinsic frequency F intrinsic to the pulsation is expressed through the use of the elapsed time; and a third process for comparing the signal strength of the second relation with a set threshold, and measuring the number of the pulsation. Consequently, the correct pulsation times are obtained in spite of the existence of the external cause noise, since only the intrinsic frequency F is used when the second relation is taken out from the first relation.  <P>COPYRIGHT: (C)2004,JPO
