  • Publication number: 20230092455
    Abstract: Systems and methods for managing access to data based on a geographic location requirement are disclosed herein. According to an aspect, a system includes a first computing device comprising a data storage manager configured to manage access to stored data based on one or more predetermined rule(s) that specifies geographic location requirement(s) for permissible access to the stored data. The manager is also configured to receive, from a second computing device, a request to access the data. Further, the manager is configured to determine a geographic location of the second computing device, determine whether the geographic location of the second computing device meets the geographic location requirement(s), and permit or deny access to the stored data by the second computing device in response to determining that the geographic location of the second computing device meets the geographic location requirement(s).

  • Patent number: 11256810
    Abstract: Systems, computing devices, and methods for authenticating privileged subsystem access by policy and by use of a security key generated at boot are disclosed herein. According to an aspect, a method includes generating a security key upon boot of a host-facing interface for a client. The method also includes communicating the security key to a baseboard management controller. Further, the method includes authenticating, to the host-facing interface commands, based on the security key. The method may also include implementing a policy associated with the security key. Further, in response to determining that a received command is not allowed by policy or the security key is not authenticated, an external server port or debug header may be disabled to prevent execution of the command.

  • Patent number: 10274201
    Abstract: A fuel injector for a gas turbine engine is disclosed. The fuel injector includes two primary tubes, a secondary tube, a primary gas gallery, and a secondary gas gallery. The two primary tubes are connected in a parallel configuration to provide a main gas fuel to the primary gas gallery. The secondary tube provides the main gas fuel to the secondary gas gallery independent from the two primary tubes and the primary gas gallery. The primary gas gallery and the secondary gas gallery provide the main gas fuel to a premix passage independently allowing for robust control of the gas turbine engine.

  • Patent number: 10234142
    Abstract: A fuel injector for a combustion engine includes an injector head including a nozzle, a premixer, and a distributor structured to distribute a plurality of different fuels to different sets of fueling orifices in the premixer. A pilot assembly of the fuel injector is coupled to the premixer and includes a first fueling passage for a first fuel and a second fueling passage for a second fuel. Multiple sets of fueling orifices are positioned within the fuel injector, the fueling orifice sets being selectively connectable to a plurality of different fuel supplies, and both located and sized so as to accommodate a wide range of flow rates to enable a combustion engine coupled with the fuel injector to operate on fuels having a range of Wobbe numbers and compositions.

  • Patent number: 10054093
    Abstract: A center body assembly for a fuel injector is disclosed. The center body assembly defines a primary liquid passage, a liquid gallery, swirl slots, and a prefilm passage. The primary liquid passage supplies liquid fuel to the liquid gallery. The liquid gallery includes a gallery discharge end and a gallery inlet end that aligns with the primary liquid passage. The liquid gallery tapers down from the gallery inlet end to the gallery discharge end. The swirl slots extend from the liquid gallery to the prefilm passage in a helical pattern. The prefilm passage includes an annular shape that turns inward towards an assembly axis of the center body assembly.
