International Classification:

B64C 3/56

Abstract:

Foldable aircraft wings are disclosed. An example aircraft includes a foldable wing having a fixed wing portion, a foldable wing portion and a hinge to pivotally couple the foldable wing portion relative to the fixed wing portion. The hinge includes a wing transition portion including wing hinge ribs and wing stub ribs, respective ones of the wing hinge ribs coupled to corresponding respective ones of the wing stub ribs. The hinge also includes a tip transition portion including tip hinge ribs, where respective ends of the tip hinge ribs positioned between corresponding respective ones of the wing hinge ribs and the wing stub ribs.

Abstract:

Aircraft wings, aircraft, and related methods. Aircraft wings include a spoiler constructed substantially of a monolithic structural body with an upper side that defines a portion of an airfoil surface of an aircraft wing. The monolithic structural body further includes a lower side, opposite the upper side, that includes a plurality of stiffening ribs that define a plurality of open voids. Methods of constructing a spoiler for an aircraft wing include forming a monolithic structural body of the spoiler.

International Classification:

H04L 29/08
H04L 12/26
G06F 9/455

Abstract:

A controller is operable to: identify virtual machines to be protected in a first storage system; identify logical volumes used by the virtual machines based on first relationship information; calculate workload, based on information of workload monitored for the identified logical volumes; and calculate size of a buffer area in the first storage system to be used for temporarily storing copy data to be sent to a second storage system in remote copy procedure of one or more remote copy pairs, based on the calculated workload, each copy pair being formed by a logical volume of the identified logical volumes in the first storage system as primary logical volume and another logical volume in the second storage system as secondary logical volume, so that the buffer area having a size equal to or greater than the calculated size can be used to manage protection of the identified virtual machines.

H01L 31/0232

US Classification:

438 69

Abstract:

A method for producing a film, the method comprising melting a layer of precursor particles on a substrate until at least a portion of the melted particles are planarized and merged to produce the film. The invention is also directed to a method for producing a photovoltaic film, the method comprising depositing particles having a photovoltaic or other property onto a substrate, and affixing the particles to the substrate, wherein the particles may or may not be subsequently melted. Also described herein are films produced by these methods, methods for producing a patterned film on a substrate, and methods for producing a multilayer structure.
