Abstract: Post-steam sterilization wet pack indicators are described. The indicators generally comprise a moisture-impermeable layer having a first surface and a moisture-indicating layer comprising a reversible colorimetric steam-sterilization-compatible moisture-indicating medium. The moisture-indicating layer is disposed on or near the first surface of the moisture-impermeable layer. The area of the moisture-indicating layer is dimensionally smaller than the moisture-impermeable layer such that the edges of the moisture-impermeable layer extend beyond the edges of the moisture-indicating layer. Articles and packages comprising wet pack indicators are also described.

Abstract: Provided is a system for directly sensing, measuring, or monitoring the temperature of an electrical conductor (31) of a power cable (10). A temperature sensitive capacitor (21C) is disposed in direct thermal contact with the electrical conductor (31). The temperature sensitive capacitor (21C) includes a dielectric material that has a dielectric constant variable with the temperature of the electrical conductor (31). The temperature of the electrical conductor (31) can be sensed, measured, or monitored by measuring the capacitance of the temperature sensitive capacitor (21C).

Abstract: A method for identifying and quantitatively analyzing an unknown organic compound in a gaseous medium. More specifically, the method provides a gas sensor array (120a, 120b, 120c, 120d) coupled to a diluting channeling gas inlet (105) with a honeycomb configuration. Each sensor (120a, 120b, 120c, 120d) in the array receives the test gas after successive dilutions. Detected gas are identified by correlating the responses of each sensor with its associated dilution.
