Abstract: A first host device housing is provided with a host device and first peripherals. The host device includes a motherboard and an upper core Input/Output (I/O) control board connected to the motherboard within the host device housing. A non-host device housing includes second peripherals and a lower core I/O control board. The host device housing is removably attachable to the non-host device housing to form a modular terminal. The second peripherals are interfaced to the host device through a cable that connects the lower core I/O control board to the upper core I/O control board. Combinations of the host device housing and a selected non-host device housing form different configurations of a modular terminal. Features available to a given configuration of the modular terminal are driven by the first peripherals and the second peripherals.

Abstract: Presubmit testing is employed in a manner that can significantly reduce processing resources and time to validate code modules. In one aspect this includes identifying components to be subject to presubmit testing, building a set of tests for the components, analyzing the set of tests to identify any tests that are hermetic, segregating identified hermetic tests from any non-hermetic tests including identifying whether any of the hermetic tests would be affected by a current change, and performing presubmit testing on all of the non-hermetic tests and on only the hermetic tests that would be affected by the current change. For any of the components that pass the presubmit testing, those components can be stored in a code repository. Thus, if a hermetic test package is determined to be unaffected by a given change, then that test will be skipped in presubmit testing.

Abstract: In order to facilitate the entity resolution and entity activity tracking and indexing, systems and methods include receiving first source records from a first database and second source records from a record database. A candidate set of second source records is determined by a heuristic search in the set of second source records. A candidate pair feature vector associated with each candidate pair of first and second source records is generated. An entity matching machine learning model predicts matching first source records for each candidate second source record based on the respective candidate pair feature vector. An aggregate quantity associated with the matching first source records is aggregated from a quantity associated with each first source record, and a quantity index for each candidate second source record is determined based the aggregate quantities. Each quantity index is displayed to a user.

The throttle ring can extend and retract in a direction substantially perpendicular to the direction of flow from the first stage impeller to the second stage impeller. A method of operating a centrifugal compressor can include actuating a throttle ring by rotating a drive ring to adjust a flow of interstage fluid into the second stage impeller.
