A film for laminating including an embossed surface, wherein the embossed surface includes a plurality of convex parts and a plurality of concave parts disposed between the plurality of convex parts, wherein each of the plurality of convex parts is surrounded by the plurality of concave parts and does not include a convex part, wherein each of the plurality of convex parts has an average area of 4.0 mm.sup.2 or less, wherein an absolute value of Skewness (Ssk) of the embossed surface is more than 0, and 1 or less, and wherein Ar of the embossed surface is 1.001 to 2, where Ar is calculated by the following Formula 1:

[00001]$\begin{array}{cc}\mathrm{Ar}=\frac{\mathrm{As}}{\mathrm{Ac}}& \left[\mathrm{Formula}1\right]\end{array}$ where, in the Formula 1, As is an average surface area of surface profiles of the plurality of convex parts comprised in a unit area (1 cm.sup.2) of the embossed surface and Ac is an average area occupied by the plurality of convex parts comprised in a unit area (1 cm.sup.2) of the embossed surface, is disclosed.

Methods and apparatus for making and using tools, for example concrete cutting blades. The tool includes a first layer and a second layer that are oppositely disposed. The first and second layers include working surfaces that support at least one working element when the working element is applied to a work piece. Additionally, an intermediate structure is included between the first and second layers. The intermediate structure can include a plurality of components extending in the area between the structural surfaces and the working surfaces.

One piece, multifunctional window assemblies for use in vehicles, equipment, or structures and methods for making them is provided. The disclosed window assembly can include a protection panel and a structural panel each formed of a plurality of nanolaminated layers. The nanolaminated window assembly is self-supporting and does not need a frame. For particular applications, such as in an aircraft, the one piece, multifunctional, nanolaminated window can be directly attached to the fuselage to provide load bearing capability, a larger window area, impact protection, ice buildup prevention, and/or electromagnetic effect protection.

A fabric processing method and component (e.g., a vehicle component) includes providing and/or arranging a first fabric charge and a second fabric charge. A multi-piece fabric assembly is formed for single stage draping by stitching together the first and second fabric charges along a neutral stitching path. The multi-piece fabric assembly is formed into a three-dimensional shape and is then impregnated with a polymeric material to form the component.

Examples of the present disclosure are related systems and methods for lead-ins for anti-fatigue floor mats. More particularly, embodiments disclose lead-ins with tapered ends with variable heights that transition from a floor level to a mat surface level to enable drop stitch-mats to be used in residential and commercial areas.

Disclosed herein are conformable protection pads, which can be integrated into articles such as clothing and protective cases. An exemplary cushioning pad can include an upper layer and a lower layer and cushioning material therebetween in a first cushioning region and one or more second cushioning regions, and one or more grooves between the first cushioning region and the second cushioning regions to enable articulation of the second cushioning regions relative to the first cushioning region.

Shaped glass structures, in particular to curved glass structures, having optically improved transmittance are provided along with methods of making such glass structures. Articles and methods described herein mask tube or reforming defects with help of refractive index-matching substances (e.g. optically clear adhesives) and/or additional glass layers. The articles and methods are applicable to any shaped glass, and is particularly useful for 3D-shaped parts for use in portable electronic devices.

The invention relates to a covering (1) for an electronic component (e.g. of the MEMS, BAW, or SAW type). The covering comprises at least one layer (5, 6, 7) having a structure (19, 20, 21) with a number of prominences (8, 9, 15) and/or depressions (10, 11, 16). The invention furthermore relates to a method for producing a covering (1) of this type.
