Abstract: Assemblies and methods for facilitating the assembly of aircraft wings to a fuselage are disclosed. In some embodiments, a wing unit includes features that are configured to define one of more parts of a pressure vessel that is partially defined by the fuselage portion. In some embodiments, the aircraft assemblies disclosed herein comprise one or more first structural interfaces that permit positional adjustment between the wing unit and the fuselage portion so that one or more second structural interfaces may be finished only after such positional adjustment. In some embodiments, the aircraft assemblies disclosed herein comprise one or more structural interfaces that are disposed outside of the wing unit in order to eliminate or reduce the need for assembly personnel to access the interior of the wing unit to carry out the structural assembly of the wing unit to the fuselage portion.

Abstract: Disclosed herein is a cross-dock management system comprises: a plurality of movable platforms configured to hold one or more pallets or parcels; at least one barcode or RFID tag positioned on each of said movable platforms, pallets, or parcels, wherein the barcode readers are configured to read the barcodes and RFID readers are configured to read the RFID tags. The data scanned by the barcode readers and RFID readers is stored in a local warehouse database and is used to determine an optimized placement and load for each movable platform in the warehouse.

Abstract: An uninterruptible power supply (UPS) system includes an enclosure and a plurality of power converter modules positioned in the enclosure, each power conversion module including a power converter circuit, a module controller circuit configured to control the power converter circuit and at least one module fan controlled by the module controller circuit. The system further includes a system controller positioned in the enclosure and configured to communicate with the module controller circuits over a communications bus and at least one exhaust fan configured to exhaust air from the enclosure and controlled by the system controller. The system controller is configured to control the at least one exhaust fan responsive to information, such as temperature and/or load information, received from the module controller circuits.

Abstract: Power control systems are provided including a digital controller configured to control gating mechanism for power switches responsive to an input from a power conversion circuit. The digital controller includes a conversion circuit, a modulation circuit and a gating control circuit. The system further includes an analog circuit comprising a filter, a current limiter and a compare circuit. The current limiter is configured to control a magnitude of a current pulled through a power convertor during a device switching operation.

Abstract: A quick release fitting including a housing assembly having a main portion and a housing arm extending from the main portion, a locking arm and a locking mechanism. The locking arm has a first locking arm end and a second locking arm end, the first locking arm is rotatably attached to the housing arm. The locking mechanism is disposed within the housing assembly, and communicates with the second locking arm end such the locking arm can be locked or unlocked to the housing assembly. When locked the locking arm is secured to the housing assembly and the housing arm, the locking arm and the housing assembly form a slot, when unlocked the locking arm is not secured to the housing assembly.

Abstract: A head and neck restraint system includes a headpiece, a saddle, and tensioners connecting the headpiece to the saddle. The headpiece resides on top of a crew member's head and the saddle includes a saddle strap residing under the crew member's buttocks. The tensioners are pneumatic muscles which contract when a flow of gas is provided by gas generators. The gas generators are triggered by a G-sensor or by the initiation of a predetermined event. Triggering signals pass through a manifold from an ejection seat, aircraft, or vehicle. Contraction of the pneumatic muscles pulls the headpiece toward the saddle, thereby restraining the head, neck, and spine. The system is worn as an undergarment or incorporated into a garment. A manual adjustment provides head support during flight.

Abstract: A sling having a generally rectangular shoulder pad with a cutout for the user's neck and four D-rings attached thereto is disclosed. A chest strap is attached to two of the D-rings, one on each end of the shoulder pad. An arm strap is attached to the two remaining D-rings. Both of the straps are formed of a resilient material to allow the user flexibility and mobility while wearing the sling. In order to create an easily adjusted attachment, each of the straps has a layer of resilient hook material on one side. At each end of each strap is a patch of hook material. The combination of hook and loop material is used to connect each end of the strap to the corresponding D-ring. An alternate embodiment uses two O-rings. Each O-ring attaches one end of both the arm strap and the chest strap to the shoulder pad.
