Web19. nov 2015 · This paper is based on the Photoplethysmography technology to measure the arterial blood oxygen saturation (SpO2) and Heart rate which are people's vital sign. In the system we design a non-invasive continuous and portable wearable watch to measure human SpO2 and Heart rate. The wearable watch uses the micro-optoelectronic sensors … WebWe refer to definition of +/- signs as describing the symmetry with respect to reflection in plane that contains both atoms, let's use an arbitrary choice of xz-plane. Wavefunctions symmetric when reflected in this plane are "+" terms, anti-symmetric are "-" terms. However, imagining reflections is not practical.
