General-purpose adaptive reasoning processor and fault-to-failure progression modeling of a multiplicity of regions of degradation for producing remaining useful life estimations
First Claim
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.

Abstract
The system contains a device and a defining signature of at least one characteristic of the device. The defining signature changing as the device accumulates damage through a period of useful lifetime in a damaged state. A sensor is in communication with the device. The sensor sensing at least one of the characteristics of the defining signature as the device accumulates damage through the period of useful lifetime. A predictive curve is provided with the defining signature mapped over the anticipated useful lifetime of the device in the damaged state. The predictive curve provides a preliminary prediction of the remaining useful lifetime of the device in the damaged state. A reasoner is in communication with the sensor. The reasoner modifies the predictive curve relative to the sensed defining signature, thereby providing a normalization of the defining signature to the predictive curve.

9. A method for predicting a remaining useful lifetime of a device in a damaged state and revising the prediction during the remaining lifetime of the device in said damaged state, said method comprising the steps of:
-
sensing at least one characteristic of a defining signature of said device over time, said at least one characteristic changing as said device accumulates damage through a period of a useful lifetime;
modifying a predictive curve relative to the sensed at least one characteristics over time, said predictive curve having said defining signature mapped over an anticipated remaining useful lifetime of said device in said damaged state, whereby said predictive curve provides a prediction of said remaining useful lifetime of said device in said damaged state. - View Dependent Claims (10, 11)

12. A method for predicting a remaining useful lifetime of a device and revising the prediction during the lifetime of the device in a damaged state, said method comprising the steps of:
-
sensing at least one characteristic of a defining signature of said device over time, said defining signature changing as said device accumulates further damage through a useful lifetime in said damaged state;
defining an attainable value for the defining signature, whereby the attainable value is indicative of damage to the device; and
modifying a predictive curve relative to the sensed at least one characteristic of said defining signature in conjunction with the sensed at least one characteristic of said defining signature achieving a value greater than the attainable value, whereby said predictive curve provides a prediction of said remaining useful lifetime of said device in said damaged state. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
