Abstract: A system includes a pad, a high-friction surface connected to the pad, a slip-resistant surface connected to the pad, and a rug engageable with the high-friction surface. The rug is selectively dis-engageable to the pad for laundering of the rug. The pad and/or rug can also include fasteners to engage the rug to a floor or other surface underlying the pad or to the pad, itself, as applicable. The fasteners can be an adhesive polyurethane gel gripper connecting the rug to the floor or high-friction surface of the pad, as applicable. The fasteners can additionally or alternatively be hook and loop type fasteners connecting the rug and the floor or high-friction surface of the pad, as applicable. The hooks of the hook and loop type fastener may be embedded in the adhesive polyurethane gel gripper. In alternatives, loops may be embedded in the adhesive polyurethane gel gripper.

Abstract: Examples of the present disclosure are related systems and methods for lead-ins for anti-fatigue floor mats. More particularly, embodiments disclose lead-ins with tapered ends with variable heights that transition from a floor level to a mat surface level to enable drop stitch-mats to be used in residential and commercial areas.

Abstract: Embodiments disclosed herein describe anti-fatigue mat systems and methods configured to provide a seamless transition between a first position allowing a user to sit on a chair positioned in front of a workstation and a second position allowing the user to stand on an upper mat positioned in front of the work station.

Abstract: A method of fabricating an anti-fatigue mat employs a pre-formed gel cushioning member that includes opposed major surfaces. One of the opposed major surfaces of the gel cushioning member is heated and liquefied. A flexible support sheet is applied and bonded to the liquefied surface of the gel cushioning member. The remaining opposed surface of the gel cushioning member is then heated and liquefied. A flexible base sheet is applied and bonded to this liquefied surface of the gel cushioning member. The method may move one of the opposed surfaces of the gel cushioning member adjacent a heat source to liquefy a portion of the gel cushioning member passing by the heat source. A flexible sheet is dispensed or applied to the liquefied portion of the gel cushioning member as the liquefied portion passes by a flexible sheet dispenser.

Abstract: A heating device of a portable nature is disclosed. The heating device of a portable nature includes a heating element, a hinged coupled to the heating element, and an arm coupled to the hinge.

Abstract: A method and apparatus are disclosed for fabricating an anti-fatigue mat that employs a layer of resilient gel material. The method employs a frame assembly that receives a flexible sheet to form the base sheet of the mat. In one embodiment, the frame assembly includes a movable frame member having an angled aperture for controlling the geometry of the gel layer when heated gel is dispensed into the aperture. In one embodiment, the frame assembly receives another flexible sheet disposed on the gel layer to form the support sheet of the mat. In one embodiment, the frame assembly may further include a cooling channel for convective or liquid cooling of liquid gel dispensed into a gel receiving cavity formed by the aperture.

Abstract: A method and apparatus are disclosed for fabricating an anti-fatigue mat that employs a layer of resilient gel material that exhibits a first durometer. The method employs a frame assembly that receives a flexible support sheet. The frame assembly includes an aperture that receives a layer of heated liquid gel which cools to form the layer of resilient gel material exhibiting the first durometer. In one embodiment, a barrier layer exhibiting a second durometer is situated on the gel layer that exhibits the first durometer. In one embodiment, the barrier layer prevents the flow of oils from the gel layer to a flexible base sheet disposed on the barrier layer. In another embodiment, the flexible base sheet may exhibit a second durometer. In either embodiment, the layers exhibiting the first and second durometer cooperate to influence the feel of the mat to the user.

Abstract: Zinc-bromine battery with recirculating electrolyte and multi-cell array, with predominant concentration of the bromine in the array at all stages of battery cycling; an array of bipolar electrode assemblies (16) with anode (26A) and cathode (26C) faces, including in each such assembly a chamber of unbound--but well contacted (electrically)--charcoal (C) stored at the cathode face and means for controlling zinc plating and deplating at the anode face; and with provision of surface area enhancement at the anode and cathode faces; electrolyte flow, pH and recirculation controls inherent in the construction, all comprising an anti-degradation combination generally.

Abstract: An instantly refuelable energy conversion system comprises a multicell array wherein each cell has a cathode, a solid anode fuel selected from the class consisting of iron, zinc and nickel and a ferric (and/or +3 valence nickel or zinc) chloride liquid oxidizer. In power delivery (discharging) e.g., using iron alone, the reactions are:At the anode, Fe.fwdarw.Fe.sup.++ + 2e yielding 0.44 volts,At the cathode, Fe.sup.+++ +e.fwdarw.Fe.sup.++ yielding 0.75 volts, the overall reaction being:Fe + 2FeCl.sub.3 .fwdarw.3FeCl.sub.2, i.e., 1.2 volts overall.These reactions are reversible for electrical charging purposes. The oxidizer is recirculated continuously and chemical reaction between the oxidizer and solid fuel in the fully charged or partially charged system is limited by a diffusion barrier between the oxidizer and fuel so that reactions therebetween are predominantly electrochemical.

Abstract: Fuel cell comprising anolyte and catholyte compartments separated by a diffusion barrier and using sodium sulfide aqueous solution as anolyte and an aqueous catholyte solution. The apparatus is controlled to maintain a positive pressure differential across the anolyte/catholyte interface in the barrier towards the anolyte side to attenuate sulfide ion migration to the catholyte and reduce solid sulfur precipitation in the catholyte and thereby attenuate consequent cathode passivation or other forms of catholyte compartment poisoning.
