Method and apparatus for providing derived glucose information utilizing physiological and/or contextual parameters

Abstract

Various methods and apparatuses for measuring a state parameter of an individual using signals based on one or more sensors are disclosed. In one embodiment, a first set of signals is used in a first function to determine how a second set of signals is used in one or more second functions to predict the state parameter. In another embodiment, first and second functions are used where the state parameter or an indicator of the state parameter may be obtained from a relationship between the first function and the second function. The state parameter may, for example, include blood glucose levels, calories consumed or calories burned by the individual. Various methods for making such apparatuses are also disclosed.

1 . An apparatus for measuring a state parameter of an individual, comprising
 a processor;   at least two sensors in electronic communication with said processor, at least one of said sensors being a physiological sensor; and   a memory storing software executable by said processor, said software including instructions for:   collecting a plurality of sensor signals from said at least two sensors; and   utilizing a first set of signals based on one or more of said plurality of sensor signals in a first function, said first function determining how a second set of signals based on one or more of said plurality of sensor signals is utilized in one or more second functions, each of said one or more second functions having an output,   wherein one or more of said outputs are used to predict said state parameter of said individual.
