SENSOR OF INDICATORS OF VITAL IMPORTANT FUNCTIONS AND METHOD OF MEASUREMENT OF INDICATORS OF VITAL LIFE IMPORTANT FUNCTIONS OF USER Russian patent published in 2019 - IPC A61B5/24 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment. FPG sensor emits light with at least three wavelengths (Y₁–Y₃) and registers the reflected light. FPG sensor contains a motion correction unit to correct motion artifacts for the detected light signals by subtracting the output signal of the detected light with a second wavelength (Y₂) from the average for the output signals of the recorded light with the first and third wavelength (Y₁, Y₃). Three wavelengths (Y₁–Y₃) have a value of approximately 550 nm. Second wavelength (Y₂) equidistant from the first and third wavelengths.

EFFECT: proposed FPG sensor.
