  • Patent number: 10957456
    Abstract: Nuclear reactor components are treated with thermal methods to increase wear resistance. Example treatments include thermal treatments using particulate or powderized materials to form a coating. Methods can use cold spray, with low heat and high velocities to blast particles on the surface. The particles impact and mechanically deform, forming an interlocking coating with the surface and each other without melting or chemically reacting. Materials in the particles and resultant coatings include metallic alloys, ceramics, and/or metal oxides. Nuclear reactor components useable with methods of increased wear resistance include nuclear fuel rods and assemblies containing the same. Coatings may be formed on any desired surface, including fuel rod positions where spacer contact and fretting is most likely.

  • Patent number: 10907553
    Abstract: A control circuit for a dual fuel generator includes a primary fuel valve to control the supply of a primary fuel, a secondary fuel valve to control the supply of a secondary fuel, a primary fuel pressure switch to detect the primary fuel, a secondary fuel pressure switch to detect the secondary fuel, and a controller. The controller is configured to receive a primary signal for availability of the primary fuel from the primary fuel pressure switch and a secondary signal for availability of the secondary fuel from the secondary and operate the primary fuel valve and the secondary fuel valve in response to the primary signal and the secondary signal. When the secondary fuel valve is open so that the secondary fuel is provided to the dual fuel generator, the control circuit is configured to ground the primary signal by connecting the primary fuel pressure switch to ground.

  • Publication number: 20200321117
    Abstract: A system and associated method provides an assessment of patient's heart health status based on past medical data. The system has a collection system, a processing system, a profiling system, and a user tools system. The collection system collects data from at least one data source having the past medical data of a plurality of patients. The processing system processes unstructured data to extract information related to patient health at different points in time. The profiling system develops a classifier based on the extracted information and other collected data. The profiling system further categorizes the extracted information into one of a plurality of health statuses at the different points in time. The user tools system generates a user interface comprising the plurality of health statuses at the different points in time. The health statuses relate to a compensated or decompensated status of the patient's heart.

  • Publication number: 20200278950
    Abstract: A system and associated method for assessing level of completeness of healthcare data storage based on collected data. The system includes a collection system, a measurement system, an expectation system, and an alerting system. In a method of assessing the health of stored data, the system collects real-time data from at least one data source, determines measurements for a plurality of parameters based on the collected data, and generates expectations for a future period of time for the plurality of parameters based on data analysis technique. The system also compares the expectations for the future period of time to subsequent measurements collected for that period of time to determine whether the subsequent measurements satisfy an expectation threshold and provide an alert to a client terminal. The alert is a result of the comparison of the expectations and the subsequent measurements and provides an assessment of data storage quality and alerts on anticipated deficiencies.

  • Publication number: 20200232909
    Abstract: A metrology system may receive a model for measuring one or more selected attributes of a target including features distributed in a selected pattern based on regression of spectroscopic scatterometry data from a scatterometry tool for a range of wavelengths. The metrology system may further generate a weighting function for the model to de-emphasize portions of the spectroscopic scatterometry data associated with wavelengths at which light captured by the scatterometry tool when measuring the target is predicted to include undesired diffraction orders. The metrology system may further direct the spectroscopic scatterometry tool to generate scatterometry data of one or more measurement targets including fabricated features distributed in the selected pattern. The metrology system may further measure the selected attributes for the one or more measurement targets based on regression of the scatterometry data of the one or more measurement targets to the model weighted by the weighting function.

  • Publication number: 20200150116
    Abstract: In various embodiments single-step ATPS paper-based diagnostic assays are provided that exploit the concept of sequential resolubilization of ATPS components to give rise to the desired phase separation behavior within paper. In one illustrative embodiment, a wick is provided for concentrating an analyte within an aqueous two-phase extraction system in a paper, where the wick comprises a paper configured to receive a sample where the paper comprises a first region containing a first component of an aqueous two-phase system (ATPS) where the first component is in a dry form, and a second region containing a second component of an aqueous two-phase system (ATPS) where the second component is in a dry form; and where said first region and the second region are disposed so that when said wick is contacted with a fluid sample, the first component of said ATPS is hydrated before the second component. In certain embodiments the first and second component are disposed so they are hydrated substantially simultaneously.
