  • Patent number: 11471082
    Abstract: A continuous glucose monitoring system may employ complex redundancy to take operational advantage of disparate characteristics of two or more dissimilar, or non-identical, sensors, including, e.g., characteristics relating to hydration, stabilization, and durability of such sensors. Fusion algorithms, Electrochemical Impedance Spectroscopy (EIS), and advanced Application Specific Integrated Circuits (ASICs) may be used to implement use of such redundant glucose sensors, devices, and sensor systems in such a way as to bridge the gaps between fast start-up, sensor longevity, and accuracy of calibration-free algorithms. Systems, devices, and algorithms are described for achieving a long-wear and reliable sensor which also minimizes, or eliminates, the need for BG calibration, thereby providing a calibration-free, or near calibration-free, sensor.

  • Patent number: 9249254
    Abstract: A multi-block thermoplastic polyurethanes system which incorporates polyhedral oligomeric silsesquioxane into conventional biodegradable thermoplastic polyurethanes built up by poly(?-caproactone) and polyethylene glycol blocks, resulting in biostability. The multi-block thermoplastic polyurethanes are synthesized from lysine-diisocyanate with poly(?-caprolactone)-diol, polyhedral oligomeric silsesquioxane-diol, and poly(ethylene glycol) using a one-step synthesis process.

  • Patent number: 9249276
    Abstract: The present invention relates to a conjugated diene polymer end-modified with an alkoxysilane derivative. More particularly, the present invention relates to an end-modified conjugated diene polymer, wherein an alkoxysilane derivative having an ether group and a dialkylamino group is bonded as end modifier to an end of a conjugated diene polymer, which is useful as a rubber material for a tire tread owing to improved compatibility with an inorganic reinforcing agent and improves dynamic mechanical properties such as wet traction, rolling resistance, Mooney viscosity, processability, etc.

  • Patent number: 9221942
    Abstract: The coating described herein attempts to provide this solution by synthesizing alkoxysilane-terminated N-substituted urea resins, then formulating them into moisture-curable single-component (1K) topside coatings. These coatings will provide greater external stability (to UV and visible radiation), cleanability, flexibility, cure times and lower VOC content than the currently qualified silicone alkyd topside coatings that are found on Navy ships. The single-component coating can include at least an alkoxysilane-terminated N-substituted urea resin, a reactive diluent, a pigment, a filler, and a catalyst. The resin can include an amino-functional silane substituted at the N-position and a non-aromatic isocyanate.
