    Abstract: A re-enterable enclosure for a cable splice includes a first cover member and a second cover member configured for engagement with each other, and movable between an open position and a closed position. The first and second cover members form a cavity for enclosing the cable splice when the cover members are in the closed position. Internal walls in at least one of the first and second cover members are configured to define a sealant containment space that at least partially surrounds the cavity. At least one latch is configured to maintain the first and second cover members in the closed position, the at least one latch configured to exert a compression force along a line extending through the sealant containment space.

    Abstract: A modular framework for data import/export in an application that allows modules/components to be independently developed for importing and exporting data related to specific entities, including the handling of dependencies between entities. The framework is metadata driven which allows new entities to be introduced in the application with new modules for importing/exporting data related to those entities, without updating modules for exporting existing entities. Each type of entity is defined with a schema that represents the logical entity such that the entity is agnostic as to how the entity data is stored in database tables. A master configuration file is created for the application that lists each entity that can be imported or exported by the application, and defines how the framework imports or exports the business entity. Additionally, dynamic batching is provided to divide large datasets into multiple batches for suitable consumption by consumers of the exported data.

The circuit further includes a plurality of switching devices to control current flow and terminal voltages in the multi-phase AC motor and a controller connected to the circuit. The controller is configured to activate the plurality of switching devices to create a DC signal in an output of the motor control device corresponding to an input to the multi-phase AC motor, determine or estimate a stator winding resistance of the multi-phase AC motor based on the DC signal, and estimate a stator temperature from the stator winding resistance. Temperature can then be controlled and regulated by DC injection into the stator windings.
