Abstract: An independent cart system with safety functions prevents unintended motion independently within different sections of the track while permitting motion along other sections of the track. A safety controller receives one or more input signals corresponding to operating conditions along the track. A safety program executing in the safety controller monitors the state of the input signals to determine whether a safety function is to be executed. When a safety program is executed, the safety controller transmits an output signal to one or more segment controllers present in one section along the track. Each segment controller is responsible for regulating current flow to the coils mounted to the corresponding track segment. In response to the signal from the safety controller, each segment controller in the section controls the power output to the coils along that section of track to achieve the safe operation desired in that segment.

Abstract: Systems and methods for a dynamic encryption model in which dynamic encryption keys are associated with an access token having an expiration time. The access token is generated for a user session of a user application seeking to make API calls to a service provider system. When the access token expires, or becomes otherwise invalid, the dynamic encryption keys are discarded, and any further API calls are made using an updated access token and updated dynamic encryption keys. The dynamic encryption keys are used to encrypt specially designated fields of API calls and/or API call results.

Abstract: The present application provides a device and method for determining formation resistivity outside casing. The device measures the electrical signal of alternating current flowing along the casing, and then calculates phase velocity, group velocity, time difference, amplitude attenuation, and phase difference of the alternating current along the casing. Using these relationships between phase velocity, group velocity, time differences, amplitude attenuation, and phase difference, the formation resistivity outside the casing is calculated.

Abstract: Systems and methods include a computer-implemented method for generating a detailed heterogeneities map of a main reservoir. Pressure data for multiple wells of a main reservoir is received during a simultaneous field shut-in of the multiple wells. A scaled rate of change of pressure for each well is determined using the pressure data for each well. Rates of change of pressure for the multiple wells are plotted using the scaled rates of change of pressure. Clusters of wells having rates of change of pressure within a threshold difference of other wells in a given cluster are determined based on the plotting. A detailed heterogeneities map of the main reservoir is generated based the clusters of wells. The heterogeneities map defines heterogeneous regions. Each region contains a set of wells assigned to the heterogeneous region based on the wells having similar rates of change of pressure.

Abstract: A plug connector assembly comprises a plug connector having an elastic locking structure for locking to a socket connector. The elastic locking structure is movable between a locking position engaged with the socket connector, and an unlocking position separated from the socket connector. An adapter of the assembly includes a pressing structure and a pull stop structure. The plug connector is received within the adapter for mating with the socket connector slidably inserted into the adapter. When the plug connector is received within the adapter, the pressing structure presses and holds the elastic locking structure in the unlocking position, and the pull stop structure abuts the elastic locking structure for preventing the plug connector from being pulled out of the adapter.

Abstract: A method for detecting the number of puffs of an electronic cigarette, includes sampling a real-time temperature of a heating unit, and determining a temperature difference; integrating the temperature difference in time to obtain an integral value I; calculating a first limit H according to the integral value I; and judging whether the real-time integral value I is beyond the first limit value H, if yes, determining that one puff of smoking happens. The method calculates a limit value that is a real-time value and varied with the change trend and change amplitude of the temperature difference. When the environment or the usage habit changes, the corresponding first limit can still be calculated according to the integral value of the current temperature difference to accurately determine the smoking behavior, thereby effectively improving the detection accuracy of the number of puffs of smoking.

Abstract: Service interruptions in a multi-tenancy, network-based storage system can be mitigated by constraining the execution of queries. In various examples, a network-based storage system may receive a request to execute a query against data maintained by the network-based storage system. The network-based storage system may perform a unit of work to execute the query, progressing through some, but not all, of a set of operations that are to be completed for completing execution of the query. Upon completion of the unit of work, query execution may be paused, query state data may be saved, and query results may be generated for consumption by the requesting computing device. In some embodiments, tokens that are usable to resume query execution based on the saved query state data may be sent to customer computing devices for resuming query execution on-demand.

Abstract: Methods, systems, and computer storage media for providing a multi-tenant system that executes graph language requests using graph operations of a graph language. A graph language request—that configures tenant data for tenants in a multi-tenant system—is executed using a graph operations engine. The graph operations engine receives and parses a graph language request that includes a list of tenants and a definition of data operations. The set of data operations of the definition are executed on a tree of data operation nodes comprising a plurality of leaf nodes and a root node. Executing the data operations is based on graph language actions (e.g., composition, transformation, and aggregation) that support asynchronously returning results data associated with configuring the Tenant data. Executing the data operations of the definition causes generation of results data (e.g., root node results or leaf node results) configuration of the tenant data in the multi-tenant system.
