  • Patent number: 10300313
    Abstract: A method and devices are described, in which a transformable fiber at a first crystal structure is shaped from its pre-determined configuration into a new shaped configuration. The new shaped configuration of the transformable fiber is inserted into a cavity of a heat and fire protective item. The new shaped configuration of the transformable fiber is heated to above its transformation temperature to a second crystal structure. The heating transforms the new shaped configuration to its pre-determined configuration, wherein the pre-determined configuration forms an air pocket within the heat and fire protective item. The transformable fiber is cooled below its transformation temperature to revert the transformable fiber back to the new shaped configuration at the first crystal structure.

  • Patent number: 8528120
    Abstract: Fire resistant garments are disclosed made from a fabric containing a fiber blend. The fiber blend contains meta-aramid fibers, fire resistant cellulose fibers, non-aromatic polyamide fibers, and optionally para-aramid fibers. The non-aromatic polyamide fibers are present in an amount sufficient to dramatically improve the abrasion resistance of the fabric without adversely interfering with the flame resistant properties. In addition to abrasion resistance, the particular blend of fibers has also been found to dramatically improve or increase various other properties. In one embodiment, the fabric is made with a herringbone weave which has been found to unexpectedly improve tear properties and porosity.

  • Patent number: 8523622
    Abstract: A rescue appliance for evacuating physically-compromised persons is disclosed. A rescue appliance includes a platform configured to support a prone evacuee, a set of wheels coupled with the platform to support the platform relative to a floor surface, and a protection assembly coupled with the platform. The protection assembly is configurable to surround the prone evacuee to protect the evacuee from a fire. The protection assembly can be configured to encase the prone evacuee. The rescue appliance can be configured to be sufficiently buoyant to support an evacuee on water to allow evacuation in a flooding emergency. Two or more rescue appliances can be coupled together to form a train so that multiple persons can be evacuated simultaneously.

  • Patent number: 8499367
    Abstract: A cooling garment comprises a phase change material and at least one of: at least one leg portion and at least one arm portion. The phase change material may have a transition temperature between solid and liquid phases of between about 60° F. to about 90° F. The at least one arm portion has the phase change material disposed therein, and the at least one leg portion has the phase change material disposed therein. The arm and leg portions may be attached to a torso portion and shorts portion, respectively, and may be removable therefrom. The cooling garment may include a sensor configured to indicate a cooling capacity of the phase change material. A portable container having a reactivation substance stored therein may be provided to reactivate the phase change material. In one embodiment, the portable container is part of a self-contained breathing apparatus. In another embodiment, the phase change material is submerged in the reactivation substance in the container.
