Claim Text:
1. A method comprising: obtaining a sequence of blood glucose reference measurements from a patient; deriving, using an electronic computing device, a non-linear mapping between sensor signal values (ISIG) and blood glucose concentration in said patient to calibrate a glucose monitor for observing glucose characteristics of said patient, said non-linear mapping based, at least in part, on temporal pairings of at least some of said blood glucose reference measurements with said sensor signal values, wherein said deriving said non-linear mapping further comprises deriving a piece-wise function that maps sensor signal values to blood-glucose concentration, the piece-wise function comprising at least one linear portion and at least one non-linear portion, the at least one non-linear portion being derived at least in part by determining coefficients e, f, and g corresponding to the following function: with said electronic computing device, using, at least in part, said determined coefficients e, f and g in calibrating subsequent sensor signal values received by said glucose monitor to provide said patient one or more estimated blood glucose levels corresponding to said subsequent sensor signal values.
