Aspects of the disclosure are directed to a panel configured for use on an aircraft nacelle, comprising: a first skin, a second skin, a first core portion coupled to the first skin and the second skin, a second core portion coupled to the first skin and the second skin, and an insert coupled to the first skin, the second skin, the first core portion, and the second core portion, the insert forming a corner fitting between the first core portion and the second core portion.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

A microfluidic package may include a fluid passage, a substrate having a substrate surface adjacent an interior of the fluid passage and components inset in the substrate, the components having component surfaces adjacent the fluid passage and substantially flush with the substrate surface.

A body-mountable device may include a first polymer layer, a second polymer layer, and a structure that includes a sensor between the first and second polymer layers. Fabricating the body-mountable device may involve providing a respective surface layer on each of one or more molding pieces, forming a first polymer layer, positioning the structure on the first polymer layer and then forming, between molding pieces, the second polymer layer over the structure positioned on the first polymer layer. The surface layer of each molding piece may facilitate release of the polymer layer or fabricated body-mountable device without disruption to the embedded structure.

Provided is an electrical connection system for a wind turbine blade that allows sharing the current between all conductors, in order to avoid voltage differences between them, avoiding internal sparks between pultruded plates, in a spar cap of the wind turbine blade. A second aspect is a wind turbine which in turn includes the wind turbine blade including the electrical bonding system. A third aspect is a method for electrically connecting conductive caps in a wind turbine blade.

A method of making a light weight component is provided. The method including the steps of: forming a metallic foam core into a desired configuration; applying an external metallic shell to an exterior surface of the metallic foam core after it has been formed into the desired configuration; forming an inlet opening and an outlet opening in the external metallic shell in order to provide a fluid path through the metallic foam core; and injecting a thermoplastic material into the metallic foam core via the inlet opening.

A sheet metal member forming method comprises placing a fiber bundle of a predetermined length, via a thermosetting resin, in a predetermined position on a surface of a sheet metal member, forming a coating film on at least a part of the sheet metal member after the placing of the fiber bundle, and while heating and drying the coating film, heat-curing the thermosetting resin to bond the fiber bundle to the sheet metal member.
