Abstract:
One or more microprocessors, comprising programming tocontrol a sensing device to obtain a series of raw signals at selected time intervals, wherein each raw signal is specifically related to a concentration or amount of blood glucose, perform a calibration step which correlates each raw signal with a measurement value indicative of the concentration or amount of blood glucose present in a subject thus providing a series of measurement values, and predict a measurement value at a further time interval which occurs either one time interval before or one time interval after the series of measurement values is obtained, wherein said series of measurement values comprises three or more discrete values, and said predicting is carried out using said series of three or more measurement values in a series function represented by: yn+1=yn+Î±&it;â€ƒ&it;(yn-yn-1)+Î±22&it;(yn-2&it;yn-1+yn-2)(7)wherein y is the measurement value of the analyte, n is the time interval between measurement values, and &agr; is a real number between 0 and 1.
