Abstract: 바이탈측정들을획득하기위한방법들, 시스템들, 컴퓨터-판독가능한매체들및 장치들이제시된다. 바이탈측정들은 PPG(photoplethysmography) 측정및 ECG(electrocardiogram) 측정의함수로써 PTT(pulse-transit time)를결정함으로써획득될수 있는혈압값을포함할수 있다. 모바일디바이스는, 사용자가휴대가능한사이즈의아우터바디, 아우터바디내에포함된프로세서, 광가이드에커플링된디스플레이, 및광 가이드에커플링된적어도하나의제1 센서를포함한다. 디스플레이는사용자내의혈관들을향해광을지향하는조명패턴을디스플레이하도록구성된다. 적어도하나의제1 센서는조명패턴으로부터사용자내의혈관들에서반사되는반사된광을측정하도록구성되고, 프로세서는측정된반사된광에적어도부분적으로기반하여혈액량의변화들을표시하는제1 측정을획득하도록구성된다.

Abstract: Methods, systems, computer-readable media, and apparatuses for obtaining vital measurements are presented. The vital measurements may include a blood pressure value that can be obtained by determining a pulse-transit time (PTT) as a function of a photoplethysmography (PPG) measurement and electrocardiogram (ECG) measurement. A mobile device includes an outer body sized to be portable for a user, a processor contained within the outer body, a display coupled to a light guide, and at least one first sensor coupled to the light guide. The display is configured to display an illumination pattern directing light toward blood vessels within the user. The at least one first sensor is configured to measure reflected light from the illumination pattern reflected off of the blood vessels within the user, wherein the processor is configured to obtain a first measurement indicative of changes in blood volume based at least in part on the measured reflected light.
