Abstract: A method for hazard detection and fire prevention during mobile refueling operation includes: accessing a geospatial position of a mobile refueling platform; detecting the geospatial position within a geospatial region as a first condition in a set of conditions, the geospatial region permitted for refueling operation; accessing a distance between the mobile refueling platform and a surface of an object proximal the mobile refueling platform; detecting the distance exceeding a distance threshold as a second condition in the set of conditions; accessing a concentration of a gas proximal the mobile refueling platform; detecting the concentration falling below a concentration threshold as a third condition in the first set of conditions; and in response to the set of conditions corresponding to a set of target conditions for mobile refueling operation, transmitting a control signal to open a fuel valve of the mobile refueling platform.

Abstract: A system includes a battery rack including a frame configured to support a battery tray, the frame including: an inlet fluidly coupled a fluid supply; and a set of columns fluidly coupled to the inlet, each column including perforations arranged on the column and facing an interior of the battery rack, and each column defining a channel configured to circulate fluid from the inlet to the perforations. The system also includes: a valve interposed between the fluid supply and the inlet; a sensor configured to generate a signal representing ambient condition proximal the battery rack; and a controller configured to trigger the valve to transition from a closed state to an open state in response to detecting a precursor condition to a fire event based on the signal.

Abstract: A system for mitigating fire within a battery storage container enclosing an energy storage system includes a sensor configured to detect a precursor condition indicative of a potential fire or explosion, a controller, and a set of extendable battery trays, each including a tray ejector and containing a set of battery cells. The controller detects a precursor condition in a battery tray via the sensor and ejects the battery tray to increase the distance between the battery tray and adjacent battery trays. The system can include a cooling channel in the battery tray configured to cool the set of battery cells, and/or a nozzle configured to direct fluid into the battery tray to suppress the precursor condition. In one variation, the system includes a door of the container configured to open, venting the interior of the container in response to detection of a precursor condition indicating a potential explosion.

Abstract: A computer system processes data records in a multi-tenant environment to ensure data quality. A plurality of records from a plurality of data sources are processed to provide a data quality metric for each field of the plurality of records based on record values in the field. A threshold range satisfying a specificity level of a data source is selected for each data quality metric. The data quality metric is compared to the threshold range to determine whether the data quality metric violates the threshold. A data quality report is provided for the plurality of records, wherein the data quality report indicates whether the data quality metric of each field violates the selected threshold range. Embodiments of the present invention further include a method and program product for processing data records in a multi-tenant environment to ensure data quality in substantially the same manner described above.

Abstract: A method, system and computer program product for ensuring quality in electronic health data. Data processing pipelines among different tenants are monitored for data artifacts generated from electronic health data, where a “data artifact” refers to the tangible by-products produced during the processing of the electronic health record datasets generated by the electronic health record systems as well as the datasets themselves. Out of the generated data artifacts, those data artifacts that are produced from the same stage of the data processing pipelines among the different tenants are aggregated. A set of metrics at various levels of a dataset hierarchy are produced from the aggregated data artifacts. Such metrics provide information about a quality of the electronic health data. A quality report, which may include flagged issues with the datasets, is then generated and presented to a user based on an analysis of the produced set of metrics.
