Method and apparatus for auto journaling of continuous or discrete body states utilizing physiological and/or contextual parameters
DCFirst Claim
1. An apparatus for deriving a state parameter of an individual, comprising:
- a processor;
a sensor for generating a sensor output signal comprising data indicative of a rate of heat flowing off said individual'"'"'s body, and a sensor for generating a sensor output signal comprising data indicative of a resistance of said individual'"'"'s skin to an electric current, said sensor output signals being directed to an electronic communication link with said processor;
wherein said processor automatically determines a context of said individual with a naï
ve Bayesian classifier and a linear regression by using said data indicative of the rate of heat flowing off said individual'"'"'s body, and said data indicative of the resistance of said individual'"'"'s skin to an electric current; and
wherein said processor utilizes said context to predict the energy expenditure of said individual.

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 calories consumed or calories burned by the individual. Various methods for making such apparatuses are also disclosed.
