Minimizing data written to disk and enabling directory change notifications in multi-volume filter environments
The amount of data that is written to disk is minimized when an overlay optimizer is used in conjunction with a write filter to prevent the overlay from becoming full. An overlay optimizer minifilter can be used to intercept writes that were initiated by the overlay optimizer's request to commit files cached in the write filter's overlay to thereby extract only the modified portions of the files that are actually stored in the overlay. The overlay optimizer minifilter can then write these modified portions of the files, as opposed to the entire files, in the overlay cache. Directory change notifications are also enabled when a write filter is employed as well as in other multi-volume filter environments. |

Aircraft wing with a moveable wing tip device for load alleviation
An aircraft is disclosed having a wing, the wing having a fixed wing with a wing tip device moveably mounted about a hinge at the tip thereof. The wing tip device is operable between a flight configuration, and a load alleviating configuration for load alleviation during flight. The aircraft includes a restraining assembly operable between a restraining mode in which the wing tip device is held in the flight configuration using a restraining force such as by a brake, and a releasing mode in which the restraining force on the wing tip device is released, such that the wing tip device may adopt the load alleviating configuration. |

Mounting system for a pressure seal of an aircraft door
An aircraft door, and, more particularly, to a mounting system for a pressure seal of an aircraft door. A mounting system may include an outer skin, a pressure seal, a clamping component, a pressure seal fastener having a head and a threaded shank, a nut, a mounting support having a clearance hole that is adapted to prevent a rotational and axial movement of the pressure seal fastener, and mounting support fasteners. Mounting support fasteners removably attach the mounting support to the outer skin. The head of the pressure seal fastener is connected to the mounting support such that a rotational and axial movement of the pressure seal fastener is prevented. The nut is removably attached to the threaded shank of the pressure seal fastener, thereby removably clamping the pressure seal between the clamping component and the mounting support. |
