Abstract
Official abstract text for this publication.
A pulse detector ( 100 ) includes a pulse wave sensor ( 10 ); a pulse wave signal filtering section ( 200 ) having a first adaptive filter ( 202 a ) and second adaptive filter ( 202 b ), and an adaptive filter switching section ( 17 ); and a pulse wave frequency analyzer ( 400 ), wherein the adaptive filter switching section ( 17 ) starts an adaptive processing of the second adaptive filter ( 202 b ) at a first time point partway through a second interval in which the first adaptive filter ( 202 a ) is continuously carrying out adaptive processing, where the second interval occurs in the first interval, and switches from the first adaptive filter ( 202 a ) to the second adaptive filter ( 202 b ) at a second time point, which is a time point after the first time point and which is the end point of the second interval.
First claim
Opening claim text (preview).
What is claimed is: 1. A pulse detector that detects a pulse signal that originates from a pulse of a subject, the pulse detector, comprising: a pulse wave sensor that outputs a pulse wave signal in which are intermixed the pulse signal and a noise signal including a body movement noise signal originating in the body movement of the subject; a pulse wave signal filtering section having a first adaptive filter and a second adaptive filter that self-adaptively adjust a frequency r…
