  • Patent number: 12619111
    Abstract: A display system comprising a backlight device having a light emitting array, a liquid crystal panel, and a color filter having one or more absorbing dyes and, optionally, one or more dye enhancement compounds, wherein the one or more absorbing dyes and the one or more dye enhancement compounds are located in at least one color set of subpixels in the color filter. The one or more absorbing dyes may be a soluble, blue light, green light, or red light absorbing dye included in blue, green, or red subpixels of the color filter. A blue light absorbing dye may reduce transmission in a wavelength range of 410-430 nm, a green light absorbing dye may reduce transmission in a wavelength range of 490-570 nm, and a red light absorbing dye may reduce transmission of wavelengths less than 620 nm.

  • Patent number: 11065953
    Abstract: 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.

  • Patent number: 10994464
    Abstract: A fabric coated or impregnated with an elastomeric material may include a polyurethane dispersion layer combined with a sealant. The fabric may be applied in such a fashion so as to enable the elimination of solvent or fluid that is associated with the elastomer. The polyurethane dispersion layer generally comprises an elastomeric material dispersed or dissolved in a liquid medium, such as, but not limited to, water. At the same time, the integrity of the elastomeric composite which is formed from the dispersion and sealant layers may be maintained in order to minimize the presence of air voids and pockets. It has thus been realized that in doing so the performance of the self-sealing volume is dramatically improved. This method of construction usually 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.

  • Patent number: 10549470
    Abstract: A method and system for forming a self-sealing volume includes an elastomeric composite structure. The structure includes layers of a cast polyurethane derived from a neat polyurethane monomer reaction mixture that does not substantially react at room temperature. The polyurethane monomer reaction layer includes a reaction product of an organic polyisocyanate and a reactive hydrogen-containing material reacted with a mixture of a monomeric polyol and polymeric polyols. The structure may further include one or more layers of a fabric that have been precoated with an aliphatic polyurethane, and one or more sealing layers. A fuel impermeable inner liner may be positioned in an inner region. The sealing layers may comprise at least one of partially vulcanized natural rubber (NR), polyisoprene (IR), styrene butadiene (SBR), or a blend of SBR with NR or IR. A dimensionally correct, self-sealing volume may be created by inflating the volume during its cure.

  • Patent number: 10323361
    Abstract: A synthetic turf system and method includes turf tufted from monofilament fibers of a thermoplastic polymer where about 1 in about 32 tuft rows comprise at least one antistatic filament per tuft. Each antistatic filament has a first nonconductive polymeric component coextensive with a second non-conductive component. One or more of the antistatic filaments substantially reduces static electrical discharge within the turf. The thermoplastic polymer for each fiber may comprise at least one of nylon, polyethylene, polypropylene, and polyester. Each tuft of the tufted turf may be twisted and each tuft may be slit to form multiple ends. The turf system may comprise stitched turf. Each antistatic filament may comprise a carbon core surrounded by a non-conductive sheath, wherein a ratio of the antistatic filament per number of tuft rows may comprise at least one of 1:2, 1:4, 1:8, and 1:16.

  • Patent number: 9194086
    Abstract: A vertically draining, particulate confinement structure may prevent side to side migration of particulate materials and may provide a way to ensure a consistent fill depth of the particulate materials. The particulate materials may include rubber granules. The vertical draining feature of the system may prevent water from accumulating on the turf surface by providing adequate vertical drainage. The vertical draining feature may be attributed to the combination of the turf surface with a confinement structure and the particulate materials that support this turf surface. The confinement structure and particulate materials also inhibit underlayment migration of the turf surface.
