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.

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.

Abstract: A technique for identifying a vein in a patient is disclosed. The technique involves the application of a thermochromic ink to a venous area on the skin of a patient (e.g., human or animal). The thermochromic ink comprises thermosensitive color-changing microcapsules that contain a proton-accepting chromogen and a desensitizer. The desensitizer possesses a melting point above which the chromogen is capable of becoming protonated, thereby resulting in a color change. Thereafter, the venous area is observed for the color change.
