A window transfer method and a window manufacturing method using a window transfer method are provided. A window transfer method includes preparing a stage, transferring the stage over a loading part on which a window layer is loaded, transferring the stage to be adjacent to an upper surface of the window layer and to allow a plurality of protrusion parts attached to side surfaces of the stage to press a slip sheet layer arranged under the window layer and exposed outside the window layer, and suctioning the window layer to a lower surface of the stage to separate the window layer from the slip sheet layer.

Enclosure parts for portable information handling systems may be made by heat pressing material layers together. The material layers may include outer fiber-reinforced thermoplastic layers and a core thermoplastic layer comprising a plurality of thermoplastic film layers. The core thermoplastic layer may be die cut to create voids that reduce weight of the enclosure part. A finishing layer may be added, along with attachment features.

Examples include a device including a nanovoided polymer element having a first surface and a second surface, a first plurality of electrodes disposed on the first surface, a second plurality of electrodes disposed on the second surface, and a control circuit configured to apply an electrical potential between one or more of the first plurality of electrodes and one or more of the second plurality of electrodes to induce a physical deformation of the nanovoided polymer element.

Described herein is a multilayer microporous film or membrane that may exhibit improved properties, including improved dielectric break down and strength, compared to prior monolayer or tri-layer microporous membranes of the same thickness. The preferred multilayer microporous membrane comprises microlayers and one or more lamination barriers. Also disclosed is a battery separator or battery comprising one or more of the multilayer microporous films or membranes. The inventive battery and battery separator is preferably safer and more robust than batteries and battery separators using prior monolayer and tri-layer microporous membranes. Also, described herein is a method for making the multilayer microporous separators, membranes or films described herein.

A method of applying an adhesive to a non-planar surface. The method includes providing a segmented film adhesive. The segmented film adhesive comprises: (i) a liner; and (ii) an adhesive layer on the liner, the adhesive layer comprising a plurality of contiguous, discrete adhesive segments. The segmented film adhesive is positioned on a non-planar surface of a first adherend so that a first portion of the discrete adhesive segments are in contact with the non-planar surface and a second portion of the discrete adhesive segments are not in contact with the non-planar surface. The liner is removed from the non-planar surface, wherein only the first portion of the discrete adhesive segments remain on the non-planar surface of the first adherend.

A breathable multilayer spun bonded polypropylene membrane having a coated pressure sensitive adhesive capable of allowing air and moisture vapor to pass through it. The adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with a surfactant and emulsified to produce bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and a pore density in the cured pressure sensitive adhesive ranging from about 4200 per inch.sup.2 to about 4600 per inch.sup.2, said pores being uniformly distributed to form a flow path through the adhesive.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

A composite material contains a nonwoven layer (i) which contains fibers formed from a first thermoplastic elastomer having meshes with a mesh size in the range from 10 to 100 μm, and a membrane layer (ii) which contains a second thermoplastic elastomer and having a layer thickness of less than 30 μm. The membrane is either pore-free (ii.1) or is porous and has pores with an average pore diameter of less than 2000 nm (ii.2). The membrane (ii) is at least partially in direct contact with the fibers of the nonwoven layer (i) and covers the mesh openings in the nonwoven layer (i) at least partially. The fibers of the first nonwoven layer (i) and the membrane (ii) in the contact area are at least partly joined to one another in an interlocking manner.

Thermal management systems are disclosed. One thermal management system includes a first element, a second element adjacent the first element, and an optional third element adjacent the second element and opposed to the first element. The first element and the optional third element include a flexible graphite article, which may have the same or different physical properties. The second element includes an insulation material, such as an aerogel-based insulation material or a porous polymer matrix such as an expanded polytetrafluoroethylene (ePTFE) membrane. Also disclosed are electronic devices that include the thermal management systems to manage the heat generated therein to reduce or eliminate hot spots or for other purposes.

The present invention relates to a water-repellent film having frost resistance, including a hygroscopic layer provided on or above a substrate, and a water-repellent layer provided on or above the hygroscopic layer, in which the water-repellent layer contains a water-repellent layer substrate and a water-repellent component attached to the water-repellent layer substrate.
