ELIAS L. ANAGNOSTOU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11209345
    Abstract: A system includes a void filter that receives sensor data employed to produce or inspect a manufactured part, the void filter generates a void data subset indicating voids detected in the manufactured part. A stress analyzer processes the void data subset from the void filter and determines coordinate data and force data for the respective detected voids in the manufactured part. At least one deterministic model analyzes the coordinate data and the force data from the stress analyzer determined for the detected voids from the void data subset. The deterministic model analyzes failure of the detected voids with respect to time and generates deterministic output data indicating failure over a deterministic timeframe. A prognostic analyzer processes the deterministic output data from the at least one deterministic model and generates a failure prediction for the as manufactured part.

  • Patent number: 9962956
    Abstract: A method and apparatus for embedding critical data directly onboard a physical asset is disclosed. Since the critical data and the asset are never separated, accurate and timely data pertinent to the asset travels with it, and may be written, read, and updated. Accurate data collection ensures a digital model/twin of the asset reflects the true physical state of the asset. Data is embedding optically or magnetically and may be read or rewritten so that information about the life/usage of the asset is continually available, right up to the current state.

  • Publication number: 20170124448
    Abstract: A system includes a physical layer that a plurality of data structures that represents a plurality of physical input data associated with product materials, assemblies, and operational use of a product of interest over various stages of product lifetime. The system includes reasoning model layer to process the data structures for the respective product stages to determine uncertainty descriptor data (UDD) for each product stage. The system includes a propagation layer that employs a plurality of virtual models that electronically describe each stage in the plurality of product stages with the UDD from each stage and propagates the UDD from each updated virtual model from each product stage between each of the plurality of virtual models across a network to mitigate compounding of error estimates across each product stage of the product lifetime to provide a product lifetime estimate.
