Patent number: 11940558Abstract: Described herein are examples of evaluating electromagnetic energy reflection data of security scans. In embodiments, a method to evaluate electromagnetic energy reflection data determines whether electronic information of a security scan contains an anomaly, and identifies an anomaly location in the electronic information corresponding to the anomaly. The method determines a subset of the electronic information corresponding to the anomaly location, determines anomaly attributes using the subset of the electronic information, and evaluates the anomaly attributes using a database of reference items by comparing anomaly attributes to respective reference characteristics of reference items or identity information. When a comparison meets the respective match criterion for the given reference item, the method assigns to the anomaly the respective identifier as an anomaly identifier.Type: GrantFiled: June 17, 2021Date of Patent: March 26, 2024Assignee: The Government of the United States of America, represented by the Secretary of Homeland SecurityInventors: Melissa Conley, John Fortune, Michael Chandarlis, William Garrett, Brian Lewis

Publication number: 20240094425Abstract: A detector for detecting optically undetectable sub-cm orbital debris. A ring detector comprising a current pulse transformer (CPT) in which a conducting wire coil is wrapped around a loop of high permeability material having a magnetic nanoparticle (MNP) core. Debris objects in low earth orbit become charged as they pass through local plasma. As each charged debris object passes through the coil-wrapped loop, its current generates an induced voltage pulse, which can be used to detect the presence of the debris object. By fielding such a detector on a satellite, a long duration survey of the debris distribution in the LEO region can be made as the satellite's altitude is systematically varied.Type: ApplicationFiled: March 3, 2023Publication date: March 21, 2024Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: William E.
