  • Publication number: 20130136904
    Abstract: A winder liner for unvulcanized rubber material comprising a first woven layer, a second woven layer, and a polymer layer. The first and second woven layers each contain a plurality of warp tape elements in a warp direction interwoven with a plurality of weft tape elements in a weft direction and a plurality of interstices between the warp and weft tape elements. The polymer layer is disposed on the inner surfaces of the first woven layer and the second woven layer and in the interstices of the first woven layer and the second woven layer. The polymer layer contains a first polymer comprising a co-polymer having at least 50% ?-olefin units and is characterized by a number-average molecular weight of about 7,000 to 500,000 g/mol, and a viscosity of between about 2,500 and 150,000 cP measured at 170° C.

  • Publication number: 20080030957
    Abstract: A heatsink having tapered geometry that improves passive cooling efficiency is discussed. A tapered geometry between heatsink heat dissipation elements, as a function of distance along a z-axis opposing gravity, decreases resistance to rarification of passively flowing cooling gas upon heating. Thus, the tapered heatsink elements result in higher velocity of gas flow and increased cooling efficiency of the heatsink. Optionally, the heatsink is made from a thermally conductive polymer allowing the heatsink to be created in complex shapes using injection molding.

  • Publication number: 20070293743
    Abstract: A placement guide apparatus with an improved hydration inducing plug used in coupling a noninvasive analyzer to a sampling site to determine analyte in the human body is disclosed. The hydration inducing plug includes at least one fluoropolymer that may be used as a coupling agent. The guide apparatus may further include an automated or semi-automated coupling fluid delivery system. Use of either of these couplers mitigates issues associated with related technology and enhances noninvasive analyte measurements, such as a near-IR diffuse reflectance based noninvasive glucose concentration analyzer.

  • Publication number: 20060211931
    Abstract: The invention provides an adaptive mount for use in coupling a noninvasive analyte property analyzer to a living tissue sample site. The adaptive mount increases precision and accuracy of sampling by relieving stress and strain on a sample prior to and/or during sampling, which results in noninvasive analyte property estimations with corresponding performance enhancement.

  • Publication number: 20060017923
    Abstract: The invention comprises a method and apparatus for enhancing the analysis of noninvasive spectra, resulting in improved analytical performance. More particularly, the invention comprises a method and apparatus for processing noninvasive spectra with an analyte filter that preferably rejects variation likely to be detrimental to the measurement system, while passing signal that probabilistically is unique to the target analyte. Subsequently, the analyte filtered data are used to estimate an analyte property, such as a glucose concentration, in the presence of noise, interferences, state changes, and/or across analyzers.
