A method is provided that integrates an autonomous energy harvesting capacity in a mobile device in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the mobile device body structure or casing to provide electrical power to the mobile device, and/or to individually electrically-powered components in the mobile device. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers appear opaque when observed from a light incident side, while allowing at least 50%, and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.

A plastic fiber composite material/aluminum laminate having: at least one flat element made of aluminum and/or an aluminum alloy and a plastic fiber composite material comprising a matrix material which has a temporarily flowable and then hardened state initially or at least under a temperature effect. The at least one flat element has etched anchoring structures, the anchoring structures have steps and undercuts, and the anchoring structures are filled and/or enclosed by the matrix material of the plastic fiber composite material. Use of the plastic fiber composite material/aluminum laminate and a method for producing the plastic fiber composite material/aluminum laminate.

Provided are methods of forming stiffened stringer panels with integrated plank structures. A skin member having an inner surface is provided. A plank is positioned onto the inner surface of the skin member. The plank extends from a first side to a second side, and each laminate ply of the set of layered laminate plies is sized to form a geometric profile for each of the first side and the second side. Each laminate ply of the set of layered laminate plies is arranged to extend from the first side to the second side. A stringer is placed onto a support tool. The support tool, and the stringer thereon, is positioned upon an uppermost laminate ply of the set of layered laminate plies. The skin member, the plank, and the stringer are joined.

A skin material includes: a design layer; and a base cloth layer. The design layer includes a surface layer and a foam layer. The base cloth layer includes a surface fabric and a back fabric, and a binding yarn that binds the surface fabric and the back fabric. The binding yarn is a thermoplastic resin fiber erected between the surface fabric and the back fabric to form a gap between the surface fabric and the back fabric. The foam layer and the surface fabric are joined. An interior material includes the skin material and a base material to which the skin material is attached. A method for producing the skin material includes joining the surface layer and the base cloth layer via a foamable adhesive to serve as the foam layer.

The present invention relates to a method of producing a glued wood product for use in construction, comprising the steps of: providing at least two wooden pieces each piece comprising at least one joining face; creating a groove in at least one of said joining faces where the groove is arranged between a pair of peripheral edges; applying adhesive onto at least one of the joining faces of at least a first of said two wooden pieces; arranging said first wooden piece so that the joining face which comprises the applied adhesive meets a corresponding joining face of said second wooden piece, wherein at least one of said two joining faces comprises said groove; pressing the two joining faces towards each other so that the adhesive is compressed between said two wooden pieces, and maintaining said pressing for a sufficient time to bond the wooden pieces to each other; wherein the applied pressing force is strong enough to force the wood tissue to collapse at a contact area until the pressure force is transmitted primarily through the adhesive, wherein said contact area is defined by the surface area whereat the two joining faces of said wooden pieces contact each other upon being pressed together.

A label including a first strip including a first end and a second end opposite the first end. The first strip includes an opaque material. The first strip further includes a first area proximate the first end. The first area includes a first length along a longitudinal axis common to the first strip. The label also includes a second strip including a third end and a fourth end opposite the third end, wherein the second strip includes a transparent material. The second strip is laminated over the first strip such that the third end is disposed outside the first area. The fourth end extends beyond the second end a distance at least equal to the first length.

A panel and a method for manufacturing thereof where the panel includes a first layer comprising a first blend of paper fragments and plastic fragments; a second layer comprising a second blend of paper fragments and plastic fragments, wherein the paper fragments and plastic fragments of the second blend are coated with an adhesive; and a third layer comprising the first blend of paper fragments and plastic fragments, wherein the second layer is disposed between the first layer and the third layer, and wherein the first layer, the second layer, and the third layer are combined to form the panel using heat and pressure. In another embodiment, the paper fragments and plastic fragments of the first blend, not the second blend, are coated with an adhesive.
