Publication number: 20220178852Abstract: Methods, system and devices for multiplexed x-ray detection systems are described. The x-ray detection systems are designed using a multiplexed array of x-ray sources that are turned on simultaneously in groups of two or more x-ray sources to form multiple exposures that are detected by a plurality of detectors. The number of exposures, as well as x-ray source characteristics and parameters, such as the number and output energy level associated with each x-ray source are determined to optimize the quality of reconstrued images or maximize the detection/classification accuracy of object(s) and/or material(s) based on a total photon energy budget.

Patent number: 11061921Abstract: The present invention provides for inline/parallel processing of data messages, specifically data response messages, to both transform and parse the data in one single pass. Parsing includes extracting common data elements (such as, error codes, fault codes, status codes and the like) from the message and deleting generic headers from the messages. In specific embodiments of the invention, the parallel processing of the present invention is made possible by implementation of a SAX parser. In such embodiments of the invention, the SAX parser implements a single filter to both transform and parse the data response messages simultaneously.Type: GrantFiled: November 22, 2019Date of Patent: July 13, 2021Assignee: BANK OF AMERICA CORPORATIONInventors: Jonathan Roger Greenblatt, Sundar R.

Patent number: 10783652Abstract: A polarization plenoptic camera that can acquire the polarization information of reflected light from an object in a single shot; i.e., in real time, to avoid issues such as motion blur and also avoid the additional system complexity that derives from mechanical scanning of a polarizer. The camera includes a polarization-sensitive focal plane array, a first microlens array having a pitch that is equal to a pitch of the pixel array; and either a second microlens array having a pitch that is greater than the pitch of the pixel array, a coded aperture mask, or a second microlens array and a coded aperture mask. A method for obtaining a plenoptic image of an object scene is disclosed.Type: GrantFiled: May 3, 2017Date of Patent: September 22, 2020Assignee: Arizona Board of Regents on Behalf of the University of ArizonaInventors: Stanley Pau, Amit Ashok

Patent number: 10303753Abstract: The present invention provides copybook flat data conversion with inline transformation. Specifically, a streaming intermediary formatted data message is generated as a result of converting/transforming a flat file format (non-XML (Extensible Markup Language) format), such as raw fixed-length field COBOL (Common Business-Oriented Language) copybook format or the like. The streaming intermediary format is not fully held in memory, but rather is directly transformed/converted, using XSLT (Extensible Stylesheet Language Transformations) processing, into a target format, such as structured XML or the like. By directly streaming the intermediary format to the XSLT process without holding the entire data message in memory, the present invention utilizes less memory and, as such, less memory is needed to be reclaimed.Type: GrantFiled: October 9, 2015Date of Patent: May 28, 2019Assignee: BANK OF AMERICA CORPORATIONInventors: Jonathan Roger Greenblatt, Sundar R.
