  • Publication number: 20210294910
    Abstract: The disclosed computer-implemented method for protecting a folder from unauthorized file modification may include receiving, from a remote device, a modify request for a target file in a folder and determining whether the folder is a protected folder. The method may also include determining, in response to determining the folder is the protected folder, whether the remote device is a trusted host. The method may further include allowing, in response to determining that the remote device is the trusted host, the modify request for the target file. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 8474265
    Abstract: A fuel nozzle for a turbine engine includes a primary fuel passageway for supplying fuel to a plurality of radially extending fuel injectors arranged around the exterior of the fuel nozzle. A secondary fuel passageway couples an upstream end of the primary fuel passageway to a downstream end of the primary fuel passageway. The secondary fuel passageway acts as a resonator tube to help reduce oscillations in the fuel flowing through the primary fuel passageway.
