Abstract: A SCBA with an air storage, a face piece with inner mask (nose cup), breathing regulator(s), a breathing valve, an exhalation valve operating at positive pressure relative to the ambient and a reservoir capable of storing the first part of an exhalation and delivering that part at the subsequent inhalation. The reservoir is positioned in the SCBA's face piece or in close proximity thereto, is in fluid contact with the inner mask, and has a shut-off valve controlled by a carbon-dioxide sensor. The operating pressure of the reservoir is maintained above ambient pressure and the operating pressure of the reservoir is between the opening pressure of the SCBA's breathing valve and the SCBA's exhalation valve.

Abstract: Provided is an assembly that includes a container with an opening for holding a volume of a liquid, a lid, and a connector attaching the container and the lid. Such an assembly can be used as a beverage container with an attached lid. Provided are methods of using such an assembly, such as by placing a liquid into the container and moving the lid so that it covers the opening. Provided are methods of making the assembly, such as by forming it as a single piece. The assemblies can be dimensioned such that can be placed adjacent to one another in a packaging while also occupying a minimum amount of space.

Abstract: A vehicular light is provided which is capable of forming an emission pattern with a good appearance at the time of lighting. The vehicular light has a light guide body having a light guide portion and a slit that penetrates the light guide portion in its thickness direction and linearly extend along a light guide path of light rays emitted from a plurality of LED light sources and guided within the light guide portion. The slit is composed of three regions including a constant width region formed in a predetermined length range toward the distal end, a tapered width region gradually narrowing toward the distal end, and a distal end region having a distal end of a curved surface shape formed in the distal end portion of the tapered width region.

Abstract: The invention provides flash imaging devices that include an optical change component that undergoes a change in response to an applied stimulus, a substrate and a stimulus element. Also provided are articles that include the subject devices, as well as methods of making and using the same.

Abstract: Aspects of the invention include color change compositions having a color former and color developer composition that transitions from a first color state to a second color state upon application of an applied stimulus and an amount of a copolymer sufficient to eliminate background color of the color former and color developer composition during transition from the first color state to the second color state. Methods for preparing and devices employing the color change compositions of the invention are also described.

Abstract: A drinking straw configured to be irreversibly attached to a container lid is provided. Aspects of the drinking straw according to certain embodiments include a proximal end, a distal end and a fastener between the proximal end and the distal end that is configured to irreversibly attach the drinking straw to the container lid. Methods for irreversibly attaching a drinking straw to a container lid by inserting the drinking straw through an orifice of the container lid are also provided. Kits having a container lid having an orifice and a drinking straw that irreversibly attaches to the container lid are also described.

Abstract: The invention involves the incorporation and enablement of elements that are incorporated into a consumer product that provide necessary balance, placement, positioning, shape, contour, and geometry that prevent a portion of the product from touching or contacting a surface on which the product is placed. The elements can be readily integrated into high-volume consumable products to increase utility, function and features of the consumable product at minimal incremental cost and adjustment to production and manufacturing processes. The invention further reports processes and compositions that enable consumable products with differentiating features, which products would otherwise be deficient for their intended use and application.
