Patent number: 11835640Abstract: An apparatus and method identify emitters. The apparatus includes a receiver, a parameter estimator, a database, and a correlator. The receiver receives an electromagnetic signal from an emitter and measures actual values of observed parameters of the electromagnetic signal.

The actual values of the observed parameters and the surmised values of the unobserved parameters characterize the emitter. The database stores one or more entries for each emitter. Each entry specifies an identifier of an emitter and exemplary values of the observed and unobserved parameters. The correlator matches the actual values of the observed parameters and the surmised values of the unobserved parameters with the exemplary values of one of the entries of the emitter from which the receiver receives the electromagnetic signal. The correlator outputs the identifier from this entry in the database.Type: GrantFiled: April 21, 2021Date of Patent: December 5, 2023Assignee: United States of America as represented by the Secretary of the NavyInventors: Gregory Knowles Fleizach, Christopher C.

Patent number: 11826823Abstract: The invention is a system for the in-situ monitoring of additive manufacturing. The system, without pre-calibration of a test sample, utilizes ultrasonic waves to conduct a layer-by-layer analysis of a three-dimensional component as it is being developed on a build plate. Resonant frequencies for each layer is measured and the difference between the resonant frequencies of consecutive layers are calculated to define a baseline frequency. Similarities or differences in baseline frequencies are used to validate the integrity of the layers of the component, and also to determine if structural inconsistencies exists. Based on these determinations, the system decides whether to continue printing or to halt printing.Type: GrantFiled: July 30, 2021Date of Patent: November 28, 2023Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Charles Nguyen, Scott Ziv
