Patent ID: 8092393

Claim:
A device for monitoring a real-time vital sign of a user, the device comprising: an article attached to the user; an optical sensor connected to the article, the optical sensor generating a real-time digitized signal corresponding to a flow of blood through an artery of the user; an accelerometer connected to the article, the accelerometer generating a real-time accelerometer data comprising a X-axis signal, a Y-axis signal and a Z-axis signal based on a movement of the user; a processor connected to the article, the processor connected to the optical sensor and the accelerometer, the processor configured to receive the real-time digitized signal from the optical sensor and configured to receive the real-time accelerometer data from the accelerometer, the processor configured to calculate the period of motion related harmonics from the real-time accelerometer data utilizing a repetitive motion pattern analyzer, the processor configured to modify the real-time digitized optical signal by suppressing the period of motion related harmonics calculated by the motion pattern analyzer to generate a modified optical signal, the processor configured to generate a real-time heart rate for the user from the modified optical signal; and a display for displaying the real-time heart rate value for the user received from the processor.
