Disposable surgical gown
A disposable surgical gown is provided. The gown includes a front panel and sleeves formed from a first spunbond layer, a nonwoven (e.g., SMS) laminate, and a liquid impervious, moisture vapor breathable elastic film disposed therebetween. The gown also includes a first and second rear panels formed from a nonwoven laminate that is air breathable and allows for an air volumetric flow rate ranging from about 20 standard cubic feet per minute (scfm) to about 80 scfm. The gown further includes a collar formed from an air breathable knit material positioned adjacent a proximal end of the gown. The collar defines a neck opening having a v-neck shape adjacent the front panel. The v-neck shape forms an angle of greater than 90° at the neck opening. The combination of features results in a reduced-glare gown that is stretchable and impervious to liquids, yet can still dissipate heat and humidity.
Method of forming a graphene device using polymer material as a support for a graphene film
The invention concerns a method of forming a graphene device, the method comprising: forming a graphene film (100) over a substrate; depositing, by gas phase deposition, a polymer material covering a surface of the graphene film (100); and removing the substrate from the graphene film (100), wherein the polymer material forms a support (102) for the graphene film (100).

Composite structures with embedded electrical grids
A composite structure of a cargo body and a method of making the same are disclosed. The composite structure includes at least one electrical grid embedded within fiber-reinforced polymer (FRP) layers. The embedded electrical grid includes a plurality of conductive fibers and a plurality of insulating fibers integrated into a polymer matrix of the FRP layers. The embedded electrical grid may be used for power distribution, structural strengthening and stiffness, and/or puncture detection.
Composite structure reinforcement utilizing thermal properties of forming elements
Forming systems and assemblies as disclosed herein comprise a composite material comprising a structural component and a resin component combined with the reinforcing component. A forming element is disposed within the composite material and has a coefficient of thermal expansion that is greater than that of the composite material. The forming element is positioned to provide a desired integral structural reinforcement and/or surface feature to the composite. The composite material may comprise one or more passages extending from a surface thereof to the forming element. The composite material may be cured by heat to take a set configuration and then allowed to cool. The cooling of the composite material and the forming element enables the forming element to contract relative to the composite material and become delaminated therefrom to facilitate easy removal, and thereby provide an improved method and assembly for making structural reinforcing features in composite structures.

Fire-rated structural OSB panels with overlaid water-resistant barrier
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.

Patient securement system for the surgical Trendelenburg position
A patient securing overlay is provided that includes a sheet of fabric for supporting a patient's torso on a surgical table. The sheet of fabric has an upper surface configured to face the patient and a lower surface configured to face a surgical table mattress or underbody support. The sheet of fabric includes friction enhancing elements applied to at least a portion of the upper surface thereof. The sheet of fabric can include an extension at a foot end of the sheet of fabric that provides material to be tucked under a foot end of the surgical table mattress or underbody support for securing the foot end of the sheet of fabric to the surgical table mattress or underbody support. The extension can include one or more friction enhancing elements.
