Abstract: A ladder strap (150) is made by joining—for example, by co-molding—a first, relatively supple material, defining a lower strap portion (155) with a second, relatively hard material defining an upper strap portion (165). The teeth (167) of the ladder strap are comprises substantially of the harder, second material. In a preferred embodiment, the first and second materials are thermoplastic urethanes, and the co-molding is done using an injection molding process. The co-molding process may be accomplished with co-injection, wherein the two materials are injected at about the same time, or the first material may be injected into a first mold cavity and allowed to partially set, after which the cavity is modified to accommodate the second material.

Abstract: Methods and system for noninvasive determination of tissue analytes utilize tissue properties as reflected in key features of an analytical signal to improve measurement accuracy and precision. Physiological conditions such as changes in water distribution among tissue compartments lead to complex alterations in the measured analytical signal of skin, leading to a biased noninvasive analyte measurement. Changes in the tissue properties are detected by identifying key features in the analytical signal responsive to physiological variations. Conditions not conducive to the noninvasive measurement are detected. Noninvasive measurements that are biased by physiological changes in tissue are compensated. In an alternate embodiment, the analyte is measured indirectly based on natural physiological response of tissue to changes in analyte concentration. A system capable of such measurements is provided.

Abstract: A repository adapter, repository adapter client and methods provide enhanced collaborative authoring of documents stored on a repository. Repository adapter clients access the repository using the repository adapter that is adapted to communicate with the clients using a bi-directional asynchronous protocol. The repository adapter communicates with the repository in accordance with a repository protocol such as the WebDAV protocol. The repository adapter performs change requests on behalf of clients in a transactional manner, in communication with the repository. Serialization of requests by clients and transactional processing by the shared repository adapter serves to reduce resource contention otherwise experienced by collaborative authors in a conventional WebDAV environment. Fine grain changes to objects, relationships and attributes may be made using the repository adapter.

Abstract: A binding includes a suspension heel loop formed by an upper member pivotally connected to the base of the binding frame.

As each frame is generated, the method randomly selects the frame synchronization signal or the inverted frame synchronization signal to be included with the frame. The frame synchronization signal is detected by a correlator and the magnitude of the correlation is used to indicate the detection of the frame synchronization signal.

Abstract: The invention relates to a method for measuring the level of a preselected analyte in a sample such as of blood of a human or animal patient by incubating the test sample with an antibody specific to the analyte to form an immunocomplex, which then interacts with the white blood cells present in or added to the sample and result in the production of oxidants. Oxidants are detected using chemiluminescent reagents. The assay is performed on the sample and in addition may include a measurement of the oxidant production resulting from a maximal stimulatory dose of immunocomplexes, providing a ratio to indicate the level of analyte in the sample. The white blood cell oxidant response may be enhanced by the inclusion of certain agents such as zymosan or complement.

Abstract: A method and apparatus for noninvasive glucose measurement measures glucose indirectly from the natural response of tissue to variations in analyte concentration. The indirect measurement method utilizes factors affected by or correlated with the concentration of glucose, such as refractive index, electrolyte distribution or tissue scattering. Measurement reliability is greatly improved by stabilizing optical properties of the tissue at the measurement site, thus blood perfusion rates at the sample site are regulated. Perfusion is monitored and stabilized by spectroscopically measuring a control parameter, such as skin temperature, that directly affects perfusion. The control parameter is maintained in a range about a set point, thus stabilizing perfusion. Skin temperature is controlled using a variety of means, including the use of active heating and cooling elements, passive devices, such as thermal wraps, and through the use of a heated coupling medium having favorable heat transfer properties.

Abstract: Methods and apparatus for estimating and removing spectral interference improve precision and robustness of non-invasive analyte measurement using Near-infrared (NIR) spectroscopy. The estimation of spectral interference is accomplished, either through multivariate modeling or discrete factor analysis, using a calibration set of samples in which the interference is orthogonal to the analyte signal of interest, or where the shape of the interference is known. Each of the methods results in a multivariate model in which the spectral interference is estimated for a new sample and removed by vector subtraction. Independent models based on classes of sample variability are used to collapse spectral interference and determine more accurately which model is best equipped to estimate the signal of interference in the new sample. Principal components analysis and other commonly known analytical techniques can be used to determine class membership.

Abstract: Embodiments of the invention comprise a design tool for designing an application interface. The design tool includes a graphical user interface (GUI) that visually represents a hierarchy of data and the relationships between the data. Thus, the design tool eliminates the need for an interface designer to have independent knowledge of the structure of the data (i.e., the data fields and relationships between the data). The design tool's GUI represents the data and the relationships between the data in a hierarchical display referred to as a data palette. An output hierarchy comprised of output levels is created as the user selects fields from the data palette to be displayed in the application's interface. When a data field is selected, the design tool automatically determines the appropriate interface component and output level of the output hierarchy using the relationships defined for the data. Output levels are associated with interface components that comprise the application's interface.

Abstract: A solution for reducing interference in noninvasive spectroscopic measurements of tissue and blood analytes is provided. By applying a basis set representing various tissue components to a collected sample measurement, measurement interferences resulting from the heterogeneity of tissue, sampling site differences, patient-to-patient variation, physiological variation, and instrumental differences are reduced. Consequently, the transformed sample measurements are more suitable for developing calibrations that are robust with respect to sample-to-sample variation, variation through time, and instrument related differences. In the calibration phase, data associated with a particular tissue sample site is corrected using a selected subset of data within the same data set. This method reduces the complexity of the data and reduces the intra-subject, inter-subject, and inter-instrument variations by removing interference specific to the respective data subset.
