A system, method and apparatus is disclosed, comprising a biomathetical model for optimizing cognitive performance in the face of sleep deprivation that integrates novel and nonobvious biomathematical models for quantifying performance impairment for both chronic sleep restriction and total sleep deprivation; the dose-dependent effects of caffeine on human vigilance; and the pheonotypical response of a particular user to caffeine dosing, chronic sleep restriction and total sleep deprivation in user-friendly software application which itself may be part of a networked system.

Method and system for measuring, predicting, and optimizing human cognitive performance

A method of estimating a body temperature of an individual based on physiological data including a heart rate received from at least one sensorand received environmental data. The physiological data and the environmental data are inputted into a model present on a processor. The model generates an estimated body temperature and an estimated physiological condition based on the inputs. The processorcompares the estimated physiological condition to a measured physiological condition in the physiological data. A controllermodifies at least one parameter in the model when the difference between the estimated physiological condition and the measured physiological condition is above a threshold.

Real-time estimation of human core body temperature based on non-invasive physiological measurements

An embodiment of the invention provides a method of estimating a body temperature of an individual where physiological data is received from at least one sensor. Environmental data is received and the physiological data and the environmental data are input into a model. The model generates an estimated body temperature and an estimated physiological condition based on the physiological data and the environmental data. A processorcompares the estimated physiological condition to a measured physiological condition in the physiological data. A controllermodifies at least one parameter in the model when the difference between the estimated physiological condition and the measured physiological condition is above a threshold.
