A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

Various enhancements of tabbed seals are provided herein with enhanced grasping functionality. Such enhancements include an anti-slip coating, a polymer adhesive layer, embossing, increasing the thickness of the tab, and/or increasing the overall surface area of the tab.

A composite structure, including a laminate that includes a set of plies, the laminate extending between a first edge and a second edge and including a rising ramp and a falling ramp. The rising ramp includes a starting point and an upper point and the falling ramp includes the upper point and an end point. Plies are partially located over their preceding ply and alternatively extend from the first edge or the second edge and are shorter than the ply located before the preceding ply so that their ends are stepped successively until they reach the top of the ramp.

A flexible flat cable (FFC) includes a first insulation layer, at least one pair of conductors, a plurality of low-k dielectric layers, two second insulation layers, and at least one shielding layer. The pair of conductors is located within the first insulation layer. Each pair of conductors includes a plurality of first conductors, and the first conductors are axially extending and arranged in parallel. The low-k dielectric layers are embedded in the first insulation layer. Each of the pair of conductors or each of the first conductors is covered and surrounded with one low-k dielectric layer. The two second insulation layers are located on two surfaces of the first insulation layer. The shielding layer is located on the two second insulation layers opposite to the first insulation layer.

A film capacitor that includes a resin layer which has a first surface and a second surface and in which there are particles on at least one of the first surface and the second surface; and a metal layer on the first surface of the resin layer, wherein there are more particles in number on the at least one of the first surface and the second surface of the resin layer than inside the resin layer.

A composite panel structure has opposing outer walls or surfaces and a core comprising a plurality of ribs extending between and connected to the outer walls and defining chambers which are filled with expanding foams, non-expanding foams, gases, or a combination thereof. The outer panel surfaces and internal chamber walls or ribs are made of woven or non-woven fibrous material impregnated with one or more resins. The panel structure may be used for making a variety of products including sports equipment such as sports paddles, surfboards, kite boards, skateboards, wakeboards, as well as construction panels for walls, ceilings or floors, display panels, panels for the vehicle industry, furniture, and other structures requiring high strength to weight properties.
