Abstract: An apparatus comprises a composite sandwich panel, a seal, and a hinge. The composite sandwich panel has a first edge in a first over-crush edge region, wherein a thickness of the composite sandwich panel decreases within the first over-crush edge region in a direction towards the first edge. The seal is bonded to the first over-crush edge region of the composite sandwich panel and extending past the first edge. The hinge is connected to the composite sandwich panel such that an axis of rotation of the hinge is positioned over the first over-crush edge region of the composite sandwich panel.

Abstract: A resilient caster guide includes a mounting flange configured to be received against a wall of a galley cart storage compartment. A flexible alignment element angularly extends from the mounting flange into the storage compartment. The flexible alignment element is configured to contact a caster extending from a base of a galley cart received in the storage compartment and to resiliently deform to maintain longitudinal alignment of the caster.

Abstract: A decorative lighting display system and method are described for providing a halo lighting effect around one or more three-dimensional figures. A panel has a recess formed in a front portion thereof and an aperture formed in a portion of the recess. A lens and an associated mask having a predetermined pattern are mounted in the recess in the panel. A decorative laminate is applied on the front portion of the panel.

Abstract: Method and apparatus for providing a modular unit through a confined entryway. The modular unit includes portions that are foldable between a transit configuration and a deployed configuration. In the transit configuration, the modular unit can fit through the confined entryway. In the deployed configuration, the modular unit may not fit through the door, but can have larger dimensions. Once past the confined entryway, the foldable portions can be quickly moved to the deployed configuration and fixed in place with a small number of pins or other fasteners. In some instances, multiple modular units may be attached together to form a larger unit. The modular units can include foldable portions, and the modular units can be connected together with a relatively small number of fasteners.
