  • Patent number: 10406079
    Abstract: The present disclosure is directed to a composite structure that is generally planar in shape. The composite structure has one or more layers; at least one of the layers includes one or more types of fibers. In one aspect, the present disclosure is directed to a composite structure including a hydrophobic support layer and a hydrophilic reservoir layer. The hydrophilic reservoir layer includes a composition that is liquid at temperatures below 30-35 degrees Celsius and that is a hydrogel at temperatures above 30-35 degrees Celsius. In order to better control the phase change of the composition and, therefore, to insulate the hydrophilic reservoir layer from warmth, the hydrophobic support layer may have a thermal conductivity that is 5 to 30 times less, in watts per meter kelvin, than water.

  • Publication number: 20180368647
    Abstract: A wiping product is disclosed that is well suited for wiping up oils and greases. More particularly, the wiping product has been engineered to wipe up and absorb oils within the interior of the product. The wiper is made from a laminate containing outer layers designed to wick away and/or adsorb oily substances from a surface. The wiper also includes an elastic middle layer that is oil absorbable. In one embodiment, the outer layers are stretch bonded to the elastic middle layer so that the outer layers gather and create void spaces within the product.

  • Publication number: 20180184876
    Abstract: Disposable cleaning wipes having a use indicator are provided that are suitable for use in home and industrial cleaning applications. The cleaning wipes comprise cellulosic fibers, an antimicrobial agent and an indicator complex, the indicator complex including (i) a colored compound selected from the group consisting of a phthalocyanine compound, an ultramarine compound, and an iron oxide compound, and (ii) a cationic agent. The indicator complex is releasably attached, by ionic bonding, to a discrete region of the fibrous sheet. The anti-microbial compound is also attached, by ionic bonding, to the fibrous sheet. Thus, in use, the indicator complex is released by the fibrous sheet commensurate with the release of antimicrobial agent. The release and loss of the indicator complex provides the user with an indication of when the antimicrobial agent within the fibrous sheet is substantially depleted and the cleaning wipe should be replaced.

  • Patent number: 9335972
    Abstract: A true random number generator comprises a ring oscillator which is triggered to start oscillating in a first mode of oscillation at an oscillation start time. The first mode of oscillation will eventually collapse to a second mode of oscillation dependent on thermal noise. A collapse time from the oscillation start time to the time at which the oscillator collapses to the second mode is measured, and this can be used to determine a random number. The TRNG can be synthesized entirely using standard digital techniques and is able to provide high randomness, good throughput and energy efficiency.
