TL;DR: An apparatus for measuring a bio signal including an apparatus that is insertable into an ear to be in close contact with an internal surface of the ear, the bio signal measurement unit having a photo plethysmography (PPG) measurement module, and an output unit for displaying the bio information generated from the control unit as mentioned in this paper.

TL;DR: A diagnosis method and apparatus for measuring blood hemoglobin concentration, oxygen saturation, pulse rate, respiration rate, or degree of aging of blood vessels using light includes an input/output unit for receiving a command for measurement from a user and for providing information on the result of a measurement to the user as mentioned in this paper.

TL;DR: In this paper, a method of removing abnormal data in a blood component analysis system using spectroscopy to estimate a concentration of a particular blood component by analyzing a photo-plethysmographic (PPG) signal obtained by radiating light of first and second wavelengths reacting to the blood component on a subject and detecting light corresponding to the first-and second wavelengths output from the subject, is presented.

TL;DR: An apparatus for diagnosing sleep apnea, which detects a temporary cessation of breathing during sleep by applying light to a part of a subject's body and processing light output therefrom, includes a light source unit for sequentially generating light of at least two different wavelengths according to a control signal, a photodetecting unit for detecting the light, and for converting the detected light signals into electric signals as mentioned in this paper.

TL;DR: In this article, a non-invasive body component measuring apparatus for measuring a concentration of a body component in a measuring portion of a living body, and a method of noninvasively measuring the concentration of the body component, is presented.
