Patent number: 11747237Abstract: A method and system of providing customizable service for an asset. The method including generating a predictive model for each asset of a fleet, each predictive model based on an operational profile for the asset and including a probability density function associated with the operational durability of the asset, establishing a maintenance strategy associated with the asset, and combining each of the predictive models to generate a compound fleet performance model, the fleet performance model including a combined probability density function. The method also includes collecting actual asset performance and maintenance data to generate actual asset metrics, determining a fleet performance profile based on the actual asset metrics indicative of a health assessment of the fleet, comparing the predicted fleet performance with the actual fleet performance, and ascertaining actionable choices for managing the assets based on a deviation of the predicted and actual fleet performance.Type: GrantFiled: May 16, 2022Date of Patent: September 5, 2023Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Thomas A. Frewen, Ozgur Erdinc, Hala Mostafa, Mei Chen, Draguna Vrabie

Patent number: 10852706Abstract: Methods and apparatus are disclosed for extracting maximal frequency response potential in controllable loads. In one example, a method includes assigning a fitness metric to at least one electrical device coupled to a power grid, assigning a frequency threshold based on the fitness metric, and transmitting the assigned frequency threshold to the at least one electrical device. The fitness metric can be based at least in part on an availability component and a quality component associated with the at least one device and the frequency threshold can cause the at least one electrical device to activate autonomously based on a frequency of the power grid.Type: GrantFiled: July 10, 2018Date of Patent: December 1, 2020Assignee: Battelle Memorial InstituteInventors: Jianming Lian, Karanjit Kalsi, Draguna Vrabie, Soumya Kundu

Patent number: 10607426Abstract: Systems and methods for the configuration of service policies for aircraft fleets and gas turbine engines are disclosed. One or more engine performance profiles may be generated based on historical engine performance data. The historical engine performance data may be retrieved based on one or more engine service parameters. A fleet performance profile may be generated based on the engine performance profiles. The engine service parameters may be varied to generate a configured engine performance profile. A configured fleet performance profile may be generated based on the configured engine performance profile.Type: GrantFiled: October 23, 2017Date of Patent: March 31, 2020Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Thomas A. Frewen, Hala Mostafa, Ozgur Erdinc, Draguna Vrabie, Mei Chen
