Abstract: In a power grid stabilization system, a second energy storage system has a larger energy storage capacity than a first energy storage system. A bidirectional AC/DC converter is connected between an AC power grid and a pair of input and output terminals of the first energy storage system. A first bidirectional DC/DC converter is connected between the pair of input and output terminals of the first energy storage system and a pair of input and output terminals of the second energy storage system.

Abstract: A power storage apparatus of one embodiment includes a storage bank including a plurality of power storage elements connected to each other; and one or plurality of first cells. The storage bank and the one or plurality of first cells are connected in series to each other. Each first cell includes a pair of input/output nodes, a bridge circuit including at least two semiconductor switching elements, and a power storage element connected to the pair of input/output nodes via the bridge circuit. A storage capacity of the power storage element of each first cell is smaller than a storage capacity of the storage bank.

Abstract: A vehicle control method for a vehicle having powertrain with an internal combustion engine and a transmission having a clutch, the method comprising of transitioning through a lash region of the transmission during clutch slipping conditions in response to a driver tip-in; and during the transition, first retarding ignition timing past maximum torque timing while increasing engine airflow, and then second, advancing ignition timing from the retarded timing while continuing to increase engine airflow.

Abstract: A method of scheduling an operation and a method of salvaging a launched test on a sample analyzer having a plurality of system resources for which there is a discrete, redundant subsystem Methods include scheduling real-time actions for execution on the subsystem or its redundant subsystem, linking the subsystem or a first redundant subsystem to another subsystem or to a second redundant subsystem, commanding the subsystem or the redundant subsystem to execute the actions for execution, executing each of the actions, monitoring execution of the actions, and re-scheduling an action for execution on a first subsystem on a corresponding discrete, redundant subsystem when an error or malfunction has occurred that may impact the launched test If re-scheduling is not possible, then the method includes trying to pause the launched test When pausing fails, the method includes marking the test bad an removing the test with minimal interference.

Abstract: A vehicle control method for transitioning through transmission lash regions is described using a variety of information, such as, for example, gear ratio, clutch slippage, etc. Further, different adjustment of spark and throttle angle is used to provide a rapid torque response while still reducing effects of the lash. Finally, transitions taking into account both slipping and non-slipping transmissions are described.

Abstract: An electronic engine controller (EEC) controls the delivery of fuel to an internal combustion engine via one or more fuel injectors by executing a background routine to measure a plurality of system conditions including airflow and engine temperature. A response value is generated as a function of an aircharge value, the temperature value and a valve effect value. The EEC detects an interrupt which occurs prior to combustion of an air/fuel mixture within each combustion chamber of said engine, and in response to the interrupt execution of the background routine is halted and a foreground routine is executed in which the airflow is measured, an updated aircharge value is generated and the response value is updated as a function of the difference in aircharge values and a predetermined response alteration value. The aircharge value is replaced with the updated aircharge value.
