Provided is a PSA sheet capable of suitably preventing bubble formation caused by outgassing. This invention provides a PSA sheet comprising a PSA layer that forms an adhesive face. In an aging test where the adhesive face is press-bonded to a glass plate and stored at 50° C. for 24 hours, the PSA sheet has at least 5% post-aging non-bonding area Sa, with Sa defined as the ratio of all areas non-bonding to the glass plate relative to the total area of the adhesive face. The non-bonding areas have parts linearly extending along the adhesive face.

Methods and apparatus are discussed for an electric powered personal transportation vehicle with electric motors powered by one or more batteries. A set of universal battery mounting hole locations and a reserved space for one or more battery housings exist on a board for the personal transportation vehicle. The reserved space on the board for the one or more battery housings that house one or more battery packs is set to not interfere with an operation of the motors or the wheels. A first battery pack containing the one or more batteries differs in at least one of i) a different amp-hour capacity, ii) a different length, width, or height, and iii) a different shape than another battery pack designed to be physically contained in the one or more battery housings and electrically connect with corresponding electrical connections in the one or more battery housings.

Disclosed are materials, articles, devices, and methods for manufacture thereof that pertain to a tracheostomy support system. The tracheostomy support system can eliminate torque on the tracheostomy tube and offload pressure caused by the tracheostomy tube on the neck skin of a patient. Additionally, the tracheostomy support system can indicate when pressure or moisture on the skin is at an unsafe level that may predispose the patient to neck skin ulceration, breakdown, or infection. The tracheostomy support system can be automatically adjusted through a closed-loop feedback system or can be manually adjusted.

The present invention discloses a multilayer composite rubber-plastic foam insulation material and a preparation method thereof. The composite rubber-plastic foam insulation material includes a two-layer structure; the two-layer structure includes an insulation layer and a first functional layer; the insulation layer and the first functional layer are both made of a rubber-plastic foam material; the first functional layer and the insulation layer are integrally molded by blending extrusion and vulcanization foaming, and the first functional layer and the insulation layer form an integral structure. The multilayer composite rubber-plastic foam insulation material provided by the present invention adopts a vulcanization foaming integral molding process, and not only ensures the thermal insulation property of the insulation layer, but also gives the functional layer corresponding functions by selecting different functional polymers, thereby satisfying a variety of personalized needs in engineering applications.

Disclosed are a laminated sheet for a vehicle interior material and a method for manufacturing the same. The laminated sheet not only includes a skin surface layer composed of a skin layer made of a liquid resin by using a casting method, thereby providing flexibility to the laminated sheet, but also includes a leather sheet layer and an intermediate layer which are bonded in a flame lamination method, thereby decreasing a peeling strength of the laminated sheet.

The present disclosure provides a laminated material including a modified polypropylene layer, a main layer, and an adhesive layer. The modified polypropylene layer includes polypropylene and anhydride-grafted polyolefin, and has an unroughened surface. The adhesive layer contacts the unroughened surface of the modified polypropylene layer and adheres to the main layer. The present disclosure further provides a method for manufacturing the laminated material.

The present disclosure relates to a co-extruded multilayer adhesive assembly comprising: a) a heat-activatable adhesive resin layer comprising a (co)polymer of one or more monomers selected from the group consisting of olefins; and b) a pressure sensitive adhesive polymeric foam layer comprising a rubber-based elastomeric material; wherein the heat-activatable adhesive resin layer is in direct contact with the pressure sensitive adhesive foam layer, and wherein the surface of the heat-activatable adhesive resin layer which is in direct contact with the pressure sensitive adhesive foam layer and the surface of the pressure sensitive adhesive foam layer which is indirect contact with the heat-activatable adhesive resin layer are free of any chemical or physical adhesion-promoting surface treatment. The present disclosure also relates to a method of manufacturing such a co-extruded multilayer adhesive assembly and uses thereof.

A three-dimensional microlattice layer comprising a plurality of interconnected filaments extending along at least three different directions from a plurality of nodes. The microlattice layer may further comprise at least one material layer extending laterally between and interconnecting at least two or more nodes. The at least one material layer may be configured to transversely and rotationally constrain the nodes to increase the overall compressive strength and stiffness of the microlattice structure. The at least one material layer may comprise a single, continuous layer and/or a plurality of material layer segments. The microlattice layer may comprise a single, continuous layer or a plurality of microlattice layer segments. The microlattice layer may be stacked, the stacked microlattice layers may further comprise one or more material layers and/or one or more impact mitigation layers.

A food delivery apparatus includes a domed shell that defines an interior space. A thermal storage device is secured to the shell so as to direct heat downward to food within the interior space.

A connector for coupling an object to a substrate has a first flexible member coupled with a second flexible member. The first and second flexible members have corresponding first and second upper regions, and first and second lower region that define first and second intermediate regions. The first upper region is coupled with the second upper region, while the first lower region is coupled with the second lower region. Through this coupling, the first intermediate region is movable relative to the second intermediate region. To minimize damage to the substrate during removal, the first and second flexible members are configured so that application of a normal force, when coupled with the substrate, causes at least the first upper region to form a critical angle sufficient to peel the connector from the substrate. The normal force is generally normal to and in a direction away from the substrate.
