1. A system for predicting a remaining useful lifetime of a device and revising the prediction during the lifetime of the device, said system comprising:

  • a defining signature comprising at least one characteristic of the device, said defining signature changing as said device accumulates damage through a period of useful lifetime in a damaged state;

    a sensor in communication with said device, said sensor sensing at least one characteristic of said characteristics of said defining signature as said device accumulates damage through said period of useful lifetime;

    a predictive curve with said defining signature mapped over an anticipated useful lifetime of said device in said damaged state, whereby said predictive curve provides a preliminary prediction of said remaining useful lifetime of said device in said damaged state; and

    a reasoner in communication with the sensor, said reasoner modifying the predictive curve relative to the sensed at least one characteristic of said at least one characteristic of said defining signature, thereby providing a normalization of said defining signature to said predictive curve.
