PULSE DETECTOR AND PULSE DETECTION METHOD
First Claim
Patent Images
1. A pulse detector that detects a pulse signal originating from the pulse of a human body, comprising:
- a pulse wave sensor that detects and outputs a first pulse wave signal in which the pulse signal and a noise signal are mixed; and
a first filtering unit that generates an adaptive spectral line enhancer based on the first pulse wave signal, divides the first pulse wave signal into a first signal and a second signal, and outputs a second pulse wave signal including at least the first signal.

8. A pulse detector that detects a pulse signal originating from the pulse of a human body, comprising:
-
a pulse wave sensor that detects and outputs a first pulse wave signal in which the pulse signal and a noise signal are mixed; a motion sensor that detects and outputs a motion signal in response to a motion of the human body; a first filtering unit that generates an adaptive filter based on a third pulse wave signal, divides the first pulse wave signal into a first signal and a second signal, and outputs a second pulse wave signal including at least the first signal; and a second filtering unit that generates an adaptive filter based on the motion signal to extract the noise signal in the second pulse wave signal and outputs the third pulse wave signal in which the noise signal is removed from the second pulse wave signal, wherein the third pulse wave signal is detected as the pulse signal. - View Dependent Claims (9)
