  • Patent number: 10090676
    Abstract: 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: Grant

  • Publication number: 20160221684
    Abstract: A method for providing electrical power and cooling for an aircraft includes: connecting a starter generator to an energy accumulator bus; selectively connecting the energy accumulator bus to a first power distribution unit in a first power channel or a second power distribution unit in a second power channel; wherein the starter generator is coupled to a shaft in an integrated power and cooling unit that includes a cooling turbine coupled to the shaft; a compressor coupled to the shaft and including an input for receiving engine bleed air or ambient air and an output for discharging compressed air; a flywheel coupled to the shaft; and a power turbine coupled to the shaft; and using energy stored in the flywheel to rotate the shaft enabling the starter generator to supply electrical power to the energy accumulator bus.

  • Patent number: 8311944
    Abstract: 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.
