  • Patent number: 10807133
    Abstract: Embodiments relate to instrumentation configuration for emergency response. Initially, instrument profiles are obtained from an instrument data source, where each instrument profile corresponds to an instrument for emergency response. Criteria are applied to each of the instrument profiles to determine performance scores for the instruments. Scenario sensors are used to collect real-time measurements at a geographic location of an emergency. At this stage, scenario parameters comprising the real-time measurements are obtained from a scenario data source. Each instrument profile is evaluated based on the scenario parameters to determine a suitability index. The performance score and the suitability index of each instrument profile is combined to determine an instrument rating. An instrument subset is selected from the instruments based on the instrument ratings.

  • Patent number: 10801987
    Abstract: Optical and electronic detection of chemicals, and particularly strong electron-donors, by 2H to 1T phase-based transition metal dichalcogenide (TMD) films, detection apparatus incorporating the TMD films, methods for forming the detection apparatus, and detection systems and methods based on the TMD films are provided. The detection apparatus includes a 2H phase TMD film that transitions to the 1T phase under exposure to strong electron donors. After exposure, the phase state can be determined to assess whether all or a portion of the TMD has undergone a transition from the 2H phase to the 1T phase. Following detection, TMD films in the 1T phase can be converted back to the 2H phase, resulting in a reusable chemical sensor that is selective for strong electron donors.

  • Patent number: 10802180
    Abstract: Three or more base optical materials are selectively combined into a trans-gradient index (GRIN) optical element (e.g., a lens). A wavelength-dependent index of refraction for light propagating perpendicular to the three or more optical materials equals: a volume fraction of a first optical material multiplied by a refractive index of the first optical material, plus a volume fraction of a second optical material multiplied by a refractive index of the second optical material, plus one minus the volume fraction of the first optical material and the volume of the second optical material all multiplied by the refractive index of a third optical material. The wavelength-dependent index of refraction distribution and a refractive index dispersion through the GRIN optical element may be independently specified from one another. A local refractive index at any point in the optical element is a fixed function of a refractive index of each individual optical material.

  • Patent number: 10775459
    Abstract: The invention relates to compounds known as “optorelaxers,” for example, spin crossover (SCO) complexes that exhibit light-induced excited state spin trapping (LIESST) effects with transient unpaired electron spins, which are created (or destroyed) by varying the level and/or wavelength of light to which the complexes are exposed. Light conditions are used to switch the optorelaxers between transient paramagnetic and diamagnetic states to provide real-time control of T1 relaxation in nuclear magnetic resonance (NMR) spectroscopy methods. The optorelaxers and methods of the invention provide increased detection sensitivity of NMR spectroscopy, with increased structural information content, while maintaining resolution for a wide variety of different NMR-active nuclei.
