Patent number: 10090676Abstract: Systems and methods are provided for distributing DC power in an aircraft. In one example, a method is provided that includes generating a plurality of DC voltages from a plurality of independent sources driven by one or more turbines of the aircraft, providing each of the plurality of DC voltages to respective dedicated DC buses, and setting a plurality of switches that selectively couples a first set of dedicated DC buses to a synchronization bus to allow for bus sharing between the first set of dedicated DC buses and bus isolation of a second set of dedicated DC buses.Type: GrantFiled: June 3, 2015Date of Patent: October 2, 2018Assignee: Northrop Grumman Systems CorporationInventors: Jeffrey A. Knowles, Keith J. Cleek, Chris K. Lee, Tad W. Theno, Ivan H. Wong

Patent number: 8311944Abstract: A transaction process system (10) provides for data transactions between parties. In a credit card transaction, the parties are the merchant (20), acquiring bank (24), card association (34), issuing bank (14), and cardholder (12). A transaction processing center (30) is positioned between the acquiring bank and the card association. The transaction processing center provides data processing channels for message-based processing (72) and filed-based processing (76). The file-based processing uses an incoming queue (80) and outgoing queue (84) to simplify the interface. The transaction processing center also provides for currency conversions and account reconciliation on a per transaction basis. The transaction processing center uses a scheduler (160) to efficiently manage the data processing resources.Type: GrantFiled: December 8, 2009Date of Patent: November 13, 2012Assignee: Mtrex, Inc.Inventors: W. Jeffrey Knowles, Russell Hales Day, David J. Matthews, Jeffrey R. Burke, Scott E. Wessman, A. Carlo Okowitz, Joseph B. Emig
