Abstract: A method, system and computer program product for retrieving both sensitive and non-sensitive content in a secure manner. After a proxy server establishes a secure connection between a client device and a web server, the client device receives the requested sensitive content, which includes an index file that contains a hash value that was generated by the web server. The web browser of the client device further issues a request to the proxy server to establish a non-secure connection to retrieve non-sensitive static content from the web server. After receiving the requested content, the web browser of the client device generates a hash value over the received content. If this generated hash value is equal to the hash value contained in the index file, then the web browser accepts the received non-sensitive static content. In this manner, both sensitive and non-sensitive content can be retrieved in a secure manner.

Abstract: A determinant assembly feature for a joint assembly and a method of assembly therefor. The joint assembly includes a structure and a web connected thereto. The structure includes a base, a pair of legs extending from the base to define a channel, and one or more location control receiving elements in either leg. The web includes a thickness control element and one or more location control elements correspondingly matched to the location control receiving elements. The method includes providing a structure comprising a base, a pair of legs extending from the base to define a channel and one or more location control receiving elements in either leg; providing a web comprising one or more location control elements and a thickness control element; and inserting the web into the structure, wherein the one or more location control elements is correspondingly matched to the one or more location control receiving elements.

Abstract: A method of controlling mixing of a flow exiting a downstream end of a primary nozzle associated with a jet engine. The method may involve coupling a shape memory alloy (SMA) element to a mixing structure disposed at the downstream edge of the primary nozzle. An electrical signal may be applied to the SMA element to heat the SMA element and induce a phase change in the SMA element. The phase change may cause an axial length of the SMA element to constrict, to cause movement of the mixing structure into a path of the flow exiting the primary nozzle.

Abstract: A computer implemented method and apparatus for creating a structural joint for an aircraft. A first composite component and a second composite component are co-joined to form the structural joint for the aircraft. A hole through the first composite component and the second composite component is created. A composite shear pin is placed through the hole. A composite collar is bonded to the composite shear pin with an adhesive.

Abstract: A method and apparatus for an airfoil, a flexible skin, and a shape control system. The flexible skin forms a control surface of the airfoil. The shape control system is capable of changing a shape of the control surface formed by the flexible skin between a plurality of shapes, wherein a gap does not occur during a changing of the shape of the control surface.

Abstract: A method of controlling mixing of a flow exiting a nozzle associated with a jet engine. The method may involve pivotally supporting a mixing structure forming a hinge device at a downstream edge of the nozzle. A shape memory alloy (SMA) element may be used to couple to the mixing structure. Heat may be generated by a flow exiting the nozzle to induce a phase change in the SMA element. The phase change may cause an axial length of the SMA element to constrict, to cause a pivoting movement of the mixing structure into a path of the flow exiting the nozzle.

Abstract: A particular method includes installing a window assembly in a structure by coupling a window frame body of the window assembly to a first surface of an interior side of an outer skin of the structure. The method also includes coupling the window frame body to a second surface of an interior side of an inner skin of the structure. The method also includes coupling the window frame body to a portion of the structure between the outer skin and the inner skin.

Abstract: A window panel adapted for installation relative to a structure. The panel includes a single piece of generally transparent injection-molded material configured to span one or more openings in the structure.
