Abstract: An example system can include a combustor of a jet turbine engine, a radio-frequency power source, a plasma-distributing structure, and a resonator having a first concentrator. The combustor can include one or more fins protruding into a combustion zone and can be configured to guide combustion of fuel along a flame path defined by the fin(s). The resonator can be configured to provide a plasma corona when excited by the power source. The plasma-distributing structure can be arranged within the combustor and proximate to the plasma corona, and can include a second concentrator. When the resonator is excited, the plasma corona can be provided proximate to the first concentrator. Further, when the plasma corona is provided proximate to the first concentrator and the plasma-distributing structure is at a predetermined voltage, an additional plasma corona can be established proximate to the second concentrator and at least partly within the flame path.

Abstract: An example system and corresponding method includes a jet engine combustor and a resonator. The combustor includes (i) a combustion zone, (ii) one or more fuel inlets for introducing fuel into the combustion zone for combustion, and (iii) one or more fins protruding into the combustion zone and configured to guide combustion of the fuel along a flame path. The resonator can have a resonant wavelength and can provide a plasma corona in the combustion zone when excited with a signal having a wavelength proximate to an odd-integer multiple of one-quarter (¼) of the resonant wavelength. A radio-frequency power source can excite the resonator with the signal so as to provide the plasma corona in the combustion zone and cause combustion of the fuel along the flame path.

Abstract: An example system and corresponding method includes a jet engine combustor and a plurality of resonators. The combustor includes (i) a combustion zone, (ii) one or more fuel inlets for introducing fuel into the combustion zone for combustion, and (iii) one or more fins protruding into the combustion zone and configured to guide combustion of the fuel along a flame path. The resonators can each have a respective resonant wavelength and can each provide a respective plasma corona in the combustion zone when excited with a respective signal having a wavelength proximate to an odd-integer multiple of one-quarter (¼) of the respective resonant wavelength. A radio-frequency power source can excite the resonators with the respective signals so as to provide the respective plasma coronas in the combustion zone and cause combustion of the fuel along the flame path.

Abstract: A graphical user interface (210) for indicating a classification (122, 124, 126, 128) of information displayed by the graphical user interface is disclosed. The graphical user interface comprises a border component of a window frame (820) that is configured to display a classification indicator (840). The classification indicator is configured to accept classification data associated with information (110). The information is information for presentation with the border component of a window frame (820). Methods of using the graphical user interface are also disclosed.

Abstract: A system for classifying information comprises a group of at least four impact factors that includes confidentiality, legal applicability, integrity, and availability (130,140,150,160). The system also includes an impact level assigned to at least one impact factor in the group of at least four impact factors; and a classification level based upon a set of zero or more impact factors from the group of at least four impact factors. Inclusion of each impact factor in the set of zero or more impact factors is based at least in part upon a comparison of the impact level assigned to each impact factor to a predetermined impact level. Methods of using the system are also provided.
