Real-Time Prognostic and Health Management System, Program Product, and Associate Methods
First Claim
1. A real-time prognostics and health management system for one or more devices, the prognostics and health management system comprising:
- a tangible and non-transitory memory preloaded with prognostics and health management signature data;
one or more sensors that are adapted to monitor one or more parameters associated with the one or more electronic devices; and
a logic device adapted to calculate an address and to access the tangible and non-transitory memory using the calculated address in real time, one or more portions of the calculated address being responsive to one or more parameter values associated with the one or more sensors so that sensor parameter data determines the address into the memory.

Abstract
Embodiments of the present invention provide a prognostics and health management (PHM) system for one or more electronic, electro-mechanical, pneudraulic and mechanical devices of an aircraft, and associated diagnostic methods and computer program products. The system includes a tangible and non-transitory memory preloaded with prognostics and health management signature data; one or more sensors that are adapted to monitor the one or more devices; and a logic device adapted to calculate an address and to access the tangible and non-transitory memory using the calculated address in real time. One or more portions of the calculated address are responsive to one or more parameter values associated with the sensors so that sensor parameter data determines the address into the memory. In the PHM system, the logic device is further adapted to generate a PHM alert in real time responsive to a value of the PHM signature data accessed at the address.

9. A diagnostic method comprising:
-
generating prognostics and health management signature data for one or more devices associated with an aircraft; preloading the prognostics and health management signature data for the one or more devices associated with the aircraft into a tangible and non-transitory memory; calculating a first address portion responsive to a first digital parameter value associated with the one or more devices; calculating a second address portion responsive to a second digital parameter value associated with the one or more devices; and accessing the prognostics and health management signature data by a logic device generating an address into the memory in real time, the address comprising the calculated first and second address portions. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A computer program product, stored on a tangible and non-transitory computer memory media, operable on a computer, the computer program product comprising a set of instructions that, when executed by the computer, cause the computer to perform the operations of:
-
generating prognostics and health management signature data for one or more devices associated with an aircraft; preloading preflight the prognostics and health management signature data for the one or more devices associated with the aircraft into a first tangible and non-transitory memory; accessing post flight a second tangible and non-transitory memory to retrieve fault log data, including a prognostics and health management alert; and analyzing the fault log data to thereby provide prognostics and health management status. - View Dependent Claims (17, 18, 19, 20)
