1. A method of determining a fused sensor measurement, the method comprising:
a. obtaining, by a processor, a number of sensor measurements from each of a plurality of sensors detecting a same type of physiological measurement;
b. determining, by the processor, a signal quality index of each sensor, wherein the signal quality index comprises determining an extent to which a sensor measurement differs from others among the number of sensor measurements obtained from each sensor;
c. determining, by the processor, a weightage of each sensor based on the signal quality index of each sensor and a difference between a filtered sensor measurement and an actual sensor measurement of such sensor;
d. determining, by the processor, a fused sensor measurement from the plurality of sensors based on the weightage of each sensor and filtered sensor measurements of each sensor obtained from a Kalman filter operation.
