Abstract
Abstract An apparatus for measuring a physiological age of a subject, including a sampling device for sampling a waveform of pulse wave produced from an arterial vessel of a subject, a storing device for storing a plurality of reference waveform models corresponding to a plurality of physiological age groups, respectively, and a determining device for selecting one of the plurality of reference waveform models which is most similar to the sampled waveform of the subject, and determining a physiological age of the subject based on the age group corresponding to the selected reference waveform model.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
An apparatus for measuring a physiological age of a subject, comprising: sampling means for sampling a waveform of a pulse wave produced from an arterial vessel of a subject; storing means for storing a plurality of reference waveform models indexed to a plurality of physiological age groups, respectively; and determining means for selecting one of said plurality of reference waveform models which is most similar to the sampled waveform of the subject, and determining a physiological age of the subject based on the age group corresponding to the selected reference waveform model.
Claim 2
Independent Claim
92 words
An apparatus for measuring a physiological age of a subject, comprising: sampling means for sampling a waveform of a pulse wave produced from an arterial vessel of a subject; storing means for storing a plurality of reference waveform models indexed to a plurality of physiological age groups, respectively; and determining means for selecting one of said plurality of reference waveform models which is most similar to the sampled waveform of the subject, and determining a physiological age of the subject based on the age group corresponding to the selected reference waveform model.
Claim 3
Dependent Claim
40 words
The apparatus as set forth in claim 1, wherein said sampling means comprises a pulse wave sensor which is pressed against said arterial vessel adapted to be so as to detect the pulse wave transmitted thereto from the arterial vessel.
Claim 4
Dependent Claim
24 words
The apparatus as set forth in claim 1, wherein said plurality of physiological age groups consist of infant, young, middle and old age groups.
Claim 5
Dependent Claim
20 words
The apparatus as set forth in claim 1, wherein said plurality of physiological age groups consist of ten age groups.
Claim 6
Dependent Claim
18 words
The apparatus as set forth in claim 1, further comprising display means for displaying the determined physiological age.
Claim 7
Dependent Claim
36 words
The apparatus as set forth in claim 1, wherein said determining means selects one of said plurality of reference waveform models which has a greatest correlation coefficient with respect to the sampled waveform of the subject.
