20130297182 | COLD START ENGINE CONTROL SYSTEMS AND METHODS - A control system includes a starter control module, a mode setting module, a throttle control module, and a fuel control module. The starter control module initiates cranking of a spark ignition direct injection (SIDI) engine in response to user actuation of an ignition switch. The mode setting module sets a mode of operation to a coldstart mode when an engine coolant temperature is less than a predetermined temperature during the cranking. The throttle control module allows a throttle valve to be biased to a predetermined open position when the SIDI engine is off and, in response to the setting of the mode to the coldstart mode, selectively closes the throttle valve relative to the predetermined open position during the cranking. The fuel control module, in response to the setting of the mode to the coldstart mode, disables direct injection of fuel for a first combustion event during the cranking. | 11-07-2013 |

20140149486 | System And Methods For Tracing Individual Transactions Across A Mainframe Computing Environment - A performance management system is provided for monitoring performance of an application across a distributed computing environment, including within one or more mainframe computers. In the mainframe environment, a transaction manager is configured to receive a transaction request from an application executing remotely from the mainframe computer. An event agent is invoked via a user exit by the transaction manager and operates to detect events caused by the handling of the transaction by the transaction manager. Upon detecting such events, the event agent generates event messages for select events associated with the transaction, where the event message includes identifying information for the transaction. A translator agent is configured to receive the event messages from the event agent and transmit the event data record to a server located remotely from the mainframe computer, where the event data record includes the identifying information for the transaction. | 05-29-2014 |
