Patent number: 11858649Abstract: A plurality of external power (“EP”) sources can be controlled with a single EP switch. A plurality of EP states can be determined, each EP state of the plurality of EP states being associated with one EP source from the plurality of EP sources. A highest EP state of the plurality of EP states can be determined. An EP indicator of the EP switch can be controlled based on the highest EP state.Type: GrantFiled: February 4, 2020Date of Patent: January 2, 2024Assignee: THE BOEING COMPANYInventors: Steven M. Walstrom, Sheverria Antony Aikens

Patent number: 10389114Abstract: A method and apparatus for providing regulated direct current power for a direct current load on an aircraft. A regulated transformer rectifier unit on an aircraft comprises a plurality of converter modules connected in parallel between an input and an output. Each converter module in the plurality of converter modules comprises a transformer rectifier unit. The plurality of converter modules are controlled by a controller to provide regulated direct current power at the output from alternating current power provided at the input from an alternating current power source on the aircraft.Type: GrantFiled: November 25, 2014Date of Patent: August 20, 2019Assignee: The Boeing CompanyInventors: Evelyn Marie Matheson, Kamiar J. Karimi, Mehdy Barekatein, Eugene V. Solodovnik, Sheverria Antony Aikens, Mark Eugene Liffring

Patent number: 10141613Abstract: A battery module system includes at least one cell and a battery module processor. The battery module processor may be configured to receive at least one cell signal associated with the at least one cell, wherein the at least one cell signal includes at least one of a temperature signal, a voltage signal, or a current signal. The battery module processor may be also configured to determine a status of the at least one cell based on the at least one cell signal. The battery module system may be configured to removably connect to a master/module interface, and to deliver power from the at least one cell to the master/module interface. The battery module system may be also configured to communicate, from the battery module processor, the status of the at least one cell to the master/module interface.Type: GrantFiled: September 20, 2016Date of Patent: November 27, 2018Assignee: The Boeing CompanyInventors: Lowell W. Schaffner, Mehdy Barekatein, Sheverria Antony Aikens, Frederic Lacaux

Patent number: 9762064Abstract: A method and apparatus for providing power stably for direct current loads. A regulated transformer rectifier unit is controlled to provide regulated direct current power for the direct current loads at an output of the regulated transformer rectifier unit from alternating current power provided by an alternating current power source to an input of the regulated transformer rectifier unit. The direct current loads comprise passive direct current loads and active direct current loads comprising active switching power supplies. The direct current loads have at least one of constant power characteristics, resistive power characteristics, inductive power characteristics, and capacitive power characteristics. A source impedance at the output of the regulated transformer rectifier unit is determined based on an aggregate load impedance of the direct current loads and stability criterion.Type: GrantFiled: November 25, 2014Date of Patent: September 12, 2017Assignee: THE BOEING COMPANYInventors: Kamiar J. Karimi, Mark Eugene Liffring, Evelyn Marie Matheson, Sheverria Antony Aikens, Eugene V. Solodovnik, Mehdy Barekatein
