Portable device having biosignal-measuring instrument
First Claim
1. A portable device having a biosignal measuring instrument, comprising:
- a first sensor portion including a first pulse waveform sensor connected to the portable device via a predetermined terminal configured to make contact with a neck of a user, thereby converting a carotid pulse waveform of the user into an electric signal, and a first electrocardiogram signal sensor detecting a first electrocardiogram signal of the user;
a second sensor portion including a second pulse waveform sensor on a surface of the portable device configured to make contact with a wrist of the user, thereby converting a radial arterial pulse waveform of the user into an electric signal, and a second electrocardiogram signal sensor measuring a second electrocardiogram signal of the user;
a waveform controller generating an electrocardiogram waveform of the user from the measured first electrocardiogram signal and second electrocardiogram signal, generating a pulse waveform of the user from the electric signals of the converted carotid pulse waveform and radial arterial pulse waveform, and detecting at least one characteristic point of the pulse waveform by referring to the electrocardiogram waveform; and
an output portion providing a result of the pulse waveform analysis based on the at least one detected characteristic point of the pulse waveform to the user.

Abstract
A portable device having a biosignal measuring instrument includes: at least one first electrocardiogram signal sensor portion on a first surface of the portable device that contacts a first hand of a user, to measure a first electrocardiogram signal of the user; at least one second electrocardiogram signal sensor portion on a second surface of the portable device that contacts a wrist of a second hand of the user, to measure a second electrocardiogram signal from the wrist; a pulse waveform sensor on the second surface and in parallel with the second electrocardiogram signal sensor portion, to sense a pulse waveform from the wrist; a waveform controller generating an electrocardiogram waveform of the user from the measured first electrocardiogram signal and second electrocardiogram signal, generating a pulse waveform of the user from the sensed pulse waveform, and detecting at least one characteristic point of the pulse waveform by referring to the electrocardiogram waveform; and an output portion providing a result of the pulse wave analysis based on the at least one detected characteristic point of the user.
