Abstract: Examples of the present disclosure describe systems and methods for a bidirectional application programming interface (API) that enables operational action functionality in a one-way transfer (OWT) system. In examples, a data request is received at a first computing environment of an OWT system, where the data request is associated with a first unidirectional dataflow having a transaction identifier. A first set of policies associated with the first computing environment is applied to the data request and the data request is transferred to a second computing environment of the OWT system. The second computing environment retrieves response data for the data request, where the response data is associated with a second unidirectional dataflow having the transaction identifier. A second set of policies associated with the second computing environment is applied to the response data and the response data is transferred to the first computing environment to fulfill the data request.

Abstract: Systems and methods for operating a driveline of a hybrid vehicle are presented. In one example, a boost phase of a procedure to close a driveline disconnect clutch may be cut short in response to an engine changing state from not rotating to rotating so that the engine may be restarted in an alternative way. The system and methods may also predict a degraded engine start from a low engine cranking speed or a long cranking time duration so that the engine may be started in an alternative way to increase a possibility of starting the engine and decrease the severity of degraded driveline disturbance.

Abstract: A variable-geometry cooling airflow management system and method for managing the cooling of a fuel cell on an aerodynamic vehicle (such as an aircraft). The cooling management is achieved by providing a conduit having a fan, radiator, and variable-geometry openings (such as variable-geometry inlet and variable-geometry outlet) at the conduit ends. Heat from the fuel cell is transferred to a coolant, which then flows through the radiator in the conduit. Cooling airflow passes over the radiator to provide fuel cell cooling. The amount of cooling airflow over the radiator is adjusted by varying the size of the variable-geometry inlet, the variable-geometry outlet, or both. Adjustments are made based on the operational parameters of the aircraft such as airspeed and flight configuration. A fan also may be located in the conduit, a speed of which is varied by the control system based on the operational parameters of the aircraft.
