An inflatable membrane may include a pattern layer and a fluorescent layer, wherein the pattern layer comprises an inner surface and an outer surface, and a pattern on the inner surface of the pattern layer, wherein at least a portion of the pattern layer formed by transferring a transferrable material from a casting plate to the inner surface, and wherein the fluorescent layer comprises an inner surface and an outer surface, the inner surface of the fluorescent layer abutting the outer surface of the pattern layer and comprising a fluorescent material which, upon receiving of light, causes the fluorescent material to emit fluorescent light and causing the pattern to be detectable by a detector.

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.

A mandrel for use in welding an air mattress having a top layer, bottom layer and at least one baffle joining the top layer and bottom layer, the mandrel includes a central mounting block; a baffle locating pin on a top surface of the central mounting block for securing the baffle to the central mounting block; a conductive sealing surface positioned along an edge of the central mounting block; a stop block positioned on the top surface of the central mounting block adjacent the sealing surface; and a bumper mounted to the central mounting block.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

Provided are an inflatable product and an inflatable product fusing process. The inflatable product comprises an upper sheet, a lower sheet, pull straps provided therebetween, and upper and lower fixing sheets having one faces away from each other respectively joined with inner surfaces of the upper and lower sheets and one faces facing towards each other not joined. The pull strap has oppositely-provided upper and lower pull strap sheets of porous material. The upper sheet, upper pull strap sheet, upper fixing sheet, lower fixing sheet, lower pull strap sheet and lower sheet are successively provided. When processing using a hot-fusing machine or high-frequency machine, the upper and lower pull strap sheets are simultaneously jointed with the upper and lower fixing sheets, therefore the inflatable product can be one-step formed and no separating sheet needs to be provided in the pull strap, thus simplifying manufacturing process and improving production efficiency.

A bleach compatible mattress cover made of a non-woven polyolefin material and defining an interior cavity. The interior cavity configured to receive a mattress structure which may include a first and second support structure disposed in the interior cavity. In certain embodiments, the mattress cover has a Moisture Vapor Transfer Rate of greater than or equal 400 to less than 10,000, 7500 or more particularly less than 5000 grams per square meter per day and a hydrostatic head of 100 cm or greater and passes ASTM 1670 and ASTM 1671.

An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

A method of manufacturing a de-icer assembly includes disposing a first welded-material layer and a second welded-material layer beneath a horn of a horn-based welding system, controlling the horn to move along a welded-portion pattern configured to weld the first welded-material layer to the second welded-material layer in the pattern of the welded-portion pattern such that inflatable portions are formed within the welded-portion pattern formed in the de-icer assembly between non-welded sections of the first welded-material layer and the second welded-material layer, and applying high-frequency energy to the first welded-material layer and a second welded-material layer using the horn such that the first welded-material layer and the second welded-material layer are welded together at areas in the shape of the welded-portion pattern to form a welded de-icer assembly.

A die-welding system for a de-icer assembly includes a die, a die base, a high energy source, and a de-icer assembly. The de-icer assembly includes a first welded-material layer and a second welded-material layer. At least one of the die and the die base includes a welded-portion pattern thereon configured to weld the first welded-material layer to the second welded-material layer in the pattern of the welded-portion pattern such that inflatable portions are formed within the welded-portion pattern formed in the de-icer assembly between non-welded sections of the first welded-material layer and the second welded-material layer.

A method of manufacturing a de-icer assembly includes positioning a first welded-material layer and a second welded-material layer between a die and a die base of a die-based welding system, wherein at least one of the die and the die base includes a welded-portion pattern configured to weld the first welded-material layer to the second welded-material layer in the pattern such that inflatable portions are formed within the welded-portion pattern formed in the de-icer assembly between non-welded sections of the first welded-material layer and the second welded-material layer, pressing the first welded-material layer and the second welded-material layer together between the die and die base, and applying high energy to the die-based welding system using a high energy source such that the first welded-material layer and the second welded-material layer are welded together at the areas in the shape of the welded-portion pattern to form a welded de-icer assembly.
