A surface covering tile has a plurality of edges extending between the face and the back surface. A pressure sensitive adhesive is disposed on the back surface and covers less than 40% of the back along each one of the plurality of edges where the back surface intersects the plurality of edges. For highly porous back surfaces, the pressure sensitive adhesive is selected and applied in a manner limiting penetration into the back surface. The amount of pressure sensitive adhesive required to affix the tile is reduced, and the tile can be optionally constructed in a manner that facilitates lateral movement of the tile during installation.

Brain motion monitoring systems and methods are disclosed that can detect interpret and/or display normal and abnormal brain motions. The devices and methods can detect Cerebrovascular Stenosis and provide for Noninvasive Intracranial Pressure Measurement.

A thermoplastic composite article comprising a porous core layer comprising a plurality of reinforcing fibers, a lofting agent and a thermoplastic material is provided. In certain instances, the article further comprises a skin layer disposed on the core layer and an adhesive layer between the core layer and the skin layer. In some configurations, the adhesive layer comprises a thermoplastic polymer and an effective amount of a thermosetting material to provide a post-molding peel strength between the skin layer and the post lofted core layer of at least 0.5 N/cm (in either or both of the machine direction or cross direction) as tested by DIN 53357 A dated Oct. 1, 1982.

Disclosed herein are methods for making asymmetric laminate structures and methods for reducing bow in asymmetric laminate structures, the methods comprising differentially heating the laminate structures during lamination or differentially cooling the laminate structures after lamination. Also disclosed herein are methods for reducing bow in asymmetric laminate structures, the methods comprising subjecting at least one substrate in the laminate structure to asymmetric tempering or annealing prior to lamination. Further disclosed herein are laminate structures made according to such methods.

A packaging material (600) comprises a first sheet material (100) and a woven fabric (200), which are arranged one above the other and are connected to one another. The first sheet material (100) contains first regions (120), in which the first sheet material (100) is expanded locally, and second regions (110), in which the first sheet material (100) is not expanded locally. The first regions (120) are arranged in each case between two second regions (110) and run in a first direction. The woven fabric (200) comprises a thread (220), wherein part of the thread (220) runs in a direction which intersects the first direction.

A multi-denier nonwoven composite fabric having a nested structure is hydraulically treated by particular process parameters to improve softness and tactile feel.

A thermally expandable sheet includes:

a first thermally expansive layer that is formed on one side of a base and contains a first thermally expandable material; and

a second thermally expansive layer that is formed on the first thermally expansive layer and contains a second thermally expandable material,

wherein the second thermally expandable material further contains white pigment.

A film capable of covering an article having a three-dimensional shape by heat expansion provided by one embodiment of the present disclosure comprises an outermost layer disposed on an outermost surface, and a polyurethane thermal adhesive layer, which contains a thermoplastic polyurethane selected from the group consisting of polyester-based polyurethanes and polycarbonate-based polyurethanes and is thermally adhered to the article during the heat expansion, wherein the fracture strength of the polyurethane thermal adhesive layer is not less than 1 MPa at 135 C., and the storage modulus at 150 C. and frequency 1.0 Hz is from 510.sup.3 Pa to 510.sup.5 Pa, and the coefficient of loss tan is not less than 0.1.

A combined material honeycomb core and methods of manufacture are presented. The combined material honeycomb core comprises a plurality of cells arranged in columns and rows formed of multiple materials, the multiple materials comprising a metallic material and either a second metallic material or a non-metallic material.
