Publication number: 20230278896Abstract: Apparatus and method for decontaminating both contaminated waters and sorbent filter media, either separately or simultaneously, in a single system. Contaminants in a liquid flowing through a reaction chamber are removed by first generating a plasma within the liquid in the chamber, with the contaminants being broken into smaller particles at the interfaces between the generated plasma and the liquid. The combined plasma-liquid solution is then passed through a solid filter, which captures the smaller contaminant particles to decontaminate the liquid. To decontaminate the filter media, plasma flows through the filter material without the presence of liquid, the plasma reacting with the filter material to remove contaminants previously adsorbed by the filter.Type: ApplicationFiled: March 3, 2023Publication date: September 7, 2023Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Scott G. Walton, William A. Maza, Michael J. Johnson, David R. Boris, Vanessa M. Breslin, Grant C. Daniels, Robert B. Balow

Patent number: 11657497Abstract: A method of identifying potential lesions in mammographic images may include operations executed by an image processing device including receiving first image data of a first type, receiving second image data of a second type, registering the first image data and the second image data by employing a CNN using pixel level registration or object level registration, determining whether a candidate detection of a lesion exists in both the first image data and the second image data based on the registering of the first image data and the second image data, and generating display output identifying the lesion.Type: GrantFiled: March 25, 2020Date of Patent: May 23, 2023Assignee: The Johns Hopkins UniversityInventors: William C. Walton, Seung-Jun Kim

Patent number: 8908919Abstract: A detection system includes processing circuitry configured to receive overhead image data divided into a plurality of image chips and receive metadata associated with the image data. The metadata includes ground sample distance information associated with the image data and provides an indication of ground area represented by each pixel within the image chips. The processing circuitry is further configured to screen the image chips for candidate detections based on a multi-stage screening process and determine whether to classify candidate detections as target detections. The process includes an intensity based screening stage, an object extraction stage that employs binary shape features to extract objects from detect positions identified based on an output of the intensity based screening stage, and a candidate detection identification stage employing template based and structural feature criteria to identify candidate detections from an output of the object extraction stage.Type: GrantFiled: May 14, 2013Date of Patent: December 9, 2014Assignee: The Johns Hopkins UniversityInventors: William C. Walton, Christopher M. Gifford, Marc A. Kolodner, Donald A. Ruffle

Patent number: 7003155Abstract: A system and method of automatically creating a NIMA certified line drawing from a National Imagery Transmission Format (NITF) image file. A grayscale (electro-optical) image and its associated metadata from a NITF file is input into the computer based system. Pre-screening operations are performed on the metadata prior to image processing to ensure that National Imagery and Mapping Agency (NIMA) requirements and criteria are met. Image processing algorithms then perform filtering, encoding, edge detection, and custom edge pattern classification procedures to create a declassified line drawing. The line drawing can then be saved in any number of standard commercial file formats.Type: GrantFiled: September 26, 2002Date of Patent: February 21, 2006Assignee: The John Hopkins UniversityInventors: William C. Walton, Cash J. Costello, Elissa M. Weidaw

Publication number: 20040149176Abstract: A table with a first work surface and a second lower work surface on a trundle table assembly. The first work surface having a table lip extending upward around the perimeter of the table while the trundle table assembly work surface does not have a lip on either end. The trundle table assembly providing a second and lower work surface so that caregivers can avoid lifting heavier children or children in wheelchairs to the height necessary to clear the table lip around the first work surface. One use for the table with trundle table assembly is a diaper changing table.Type: ApplicationFiled: January 21, 2004Publication date: August 5, 2004Applicant: Sabre Group, Inc.
