System for monitoring health, wellness and fitness having a method and apparatus for improved measurement of heat flow

The present invention relates to a system for monitoring health, wellness and fitness, having a method and apparatus for improved measurement of heat flow, and in particular, to a system for collecting, using a sensor device, and storing at a remote site data relating to an individual's physiological state, physiological pattern, lifestyle, and various contextual parameters, and making such data and analytical information based on such data available to the individual, preferably over an electronic network. The present invention also relates to improved means and methods for measuring heat flow between a living body and an ambient environment and for generating information related thereto. Means and methods for measuring heat flux between a living body and an ambient atmosphere and for generating information related thereto. Means include a heat pipe configuration comprising at least one heat conduit in thermal communication with a heat flux sensor and a surface of a living body. Methods include employing such a heat pipe configuration. Heat pipe configuration may be used in a device included in a system for detecting, monitoring and reporting human physiological information.
