A shower system for use in a shower environment includes a pre-fabricated tileable receptor configured for installing in the shower environment to provide a base for installing a tiled surface on top of the tileable receptor. The tileable receptor includes a drain area and a sloped portion configured to direct a liquid toward the drain area. The tileable receptor is made of a layered material including a structural layer and a membrane layer. The structural layer is configured to maintain a shape of the sloped portion. The membrane layer is supported by the structural layer and includes a surface texture. The membrane layer facilitates a mechanical bond with a tile adhesive material.

An acoustic structure presenting a front surface and a back surface is provided. The acoustic structure includes a support layer comprising the back surface, a honeycomb core comprising a thickness defined between a back and a front, and a plurality of walls that define a plurality of honeycomb cells, wherein the plurality of honeycomb cells extend through the thickness of the honeycomb core opening out toward at least the front, and wherein the back of the honeycomb core is affixed to the support layer, a mesh layer affixed to the front of the honeycomb core, and a knit fabric layer affixed to the mesh layer and conforming to the front surface of the acoustic structure.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

Provided is a method of producing a skin-covered product in which a skin is bonded to a base material, the method capable of performing a roll treatment by a robot to improve work efficiency and quality, and reducing the number of production steps for producing the skin-covered product by immediately performing a rolling step after trimming the bonded skin by vacuum molding.

The method of producing a skin-covered product in which the skin is bonded to the base material according to the present invention includes (1) an integration step of integrating the base material and the skin by vacuum molding while drawing the skin to the base material such that the skin is rolled on a back surface side, (2) a skin trimming step of cutting an extra portion around the skin rolled on a back side in accordance with a form of the base material, and (3) a rolled portion welding step of moving the skin, rolled by a horn tip of an ultrasonic welding machine manually or by a robot, to a skin end portion while sliding the skin on the back surface side of the base material, and then ultrasonically welding the base material and the skin by ultrasonic welding.
