Ear type apparatus for measuring a bio signal and measuring method therefor
TLDR
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.Abstract:
An apparatus for measuring a bio signal including a bio signal measurement unit, which 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 for radiating light of different wavelengths onto the internal surface of the ear, detecting light transmitted through the ear, and outputting a PPG signal including bio information, a control unit having a PPG signal processor for generating the bio information using the PPG signal measured by the PPG measurement module, and an output unit for displaying the bio information generated from the control unit.read more

Patent
Medical sensor and technique for using the same
TL;DR: In this article, a medical sensor is adapted to account for factors that cause irregularities in pulse oximetry measurements or other spectrophotemetric measurements using surface features that reduce the amount of outside light or shunted light that impinge the detecting elements of the sensor.
Patent
Body-worn vital sign monitor
TL;DR: In this paper, a body-worn vital sign monitor that measures a patient's vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (i.e. resting, walking, convulsing, falling) and posture (upright, supine).
Patent
Motion compatible sensor for non-invasive optical blood analysis
TL;DR: In this paper, it has been determined that a sensor placed on a nail, in particular a thumbnail, exhibits the characteristics of having the red and infrared signals correlated when used for pulse oximetry, and the resulting signals correlate to arterial oxygen saturation.
Patent
Body-worn monitor for measuring respiration rate
TL;DR: In this paper, an impedance pneumography (IP) sensor is connected to at least two electrodes, and a processing system that receives and processes signals from the electrodes to measure an IP signal.
Patent
Body-worn pulse oximeter
TL;DR: In this article, a body-worn system that continuously measures pulse oximetry and blood pressure, along with motion, posture, and activity level, from an ambulatory patient is presented.

Physiological signal monitoring system
TL;DR: In this article, a photoplethysmography (PPG) sensor, a processing device, and a Web site server are used for determining, displaying and analyzing various cardiovascular parameters.
Patent
Plethysmograph pulse recognition processor
TL;DR: In this article, an intelligent rule-based processor was used to recognize individual pulses in a pulse oximeter-derived photo-plethysmograph waveform, including the characteristic dicrotic notch.
Patent
Single site, multi-variable patient monitor
TL;DR: In this article, an apparatus for monitoring multiple physiological variables of a patient at a single site on the patient can be used to facilitate assessment of the patient's well being during medical surgery as well as during ambulatory monitoring, home monitoring, procedure monitoring and similar situations.
Patent
Pulse oximeter and method of operation
TL;DR: In this article, a sensor for use in an optical measurement device and a method for non-invasive measurement of a blood parameter is presented, which includes sensor housing, a source of radiation coupled to the housing, and a detector assembly coupled with the housing.
