| 20090000673 | Electronically controlled pressure regulator for a mechanical returnless fuel system - A pressure regulator as part of a vehicle fuel pump module may lie within a pressure regulator case, be powered by a battery and controlled by a controller. The pressure regulator may employ a spring secured by a spring holder and held within a pressure regulator spring case. A sealing pressure plate sub-assembly may have a ball element at the top and both may pass through the spring and spring holder and contact a solenoid plunger of a solenoid that is located at an end of the spring case. When the controller activates the solenoid, the solenoid plunger moves and contacts the pressure plate sub-assembly to effect temporary stoppage of the flow of fuel to jet pumps and to a reservoir. The solenoid case may have a diameter equal to, less than, or greater than the diameter of the pressure regulator spring case. | 01-01-2009 |

A fuel injector cup may define a notch through which the first prong and the second prong reside to secure the fuel injector to the fuel injector cup, which is attached to the rail. A first prong interior straight wall surface and a second prong interior straight wall surface may face the gap and be parallel. The prongs may define entry contact surfaces and exit contact surfaces that meet at prescribed angles to aid in insertion and hinder retraction of the injector tab from the injector cup. The tab defines a solid head portion below the gap that resides in the notch. | 09-29-2011 |
| 20110265765 | DIRECT INJECTION PUMP CONTROL STRATEGY FOR NOISE REDUCTION - A pump may have a first chamber and a solenoid coil to control movement of a first valve member. A second chamber may have a second valve member to control fluid moving into a third chamber. A first fluid passageway may link the first and second chambers, a second passageway may link second and third chambers and a third passageway may link third and fourth chambers. After pressurizing the third chamber causing fluid to flow into and leave a fourth chamber, the third chamber depressurizes due to downward movement of a plunger. Upon depressurization with a solenoid coil energized, second valve member floats and then moves against a valve seat. While the second valve member is moving toward the valve seat, the solenoid coil is de-energized causing the first valve member to move and strike the second valve member when the second valve member is moving at maximum velocity. | 11-03-2011 |

| 20090083238 | STOP-AND-RESTART STYLE EXECUTION FOR LONG RUNNING DECISION SUPPORT QUERIES - Stop-and-restart query execution that partially leverages the work already performed during the initial execution of the query to reduce the execution time during a restart. The technique selectively saves information from a previous execution of the query so that the overhead associated with restarting the query execution can be bounded. Despite saving only limited information, the disclosed technique substantially reduces the running time of the restarted query. The stop-and-restart query execution technique is constrained to save and reuse only a bounded number of records (intermediate records or output records) thereby releasing all other resources, rather than some of the resources. The technique chooses a subset of the records to save that were found during normal execution and then skipping the corresponding records when performing a scan during restart to prevent the duplication of execution. A skip-scan operator is employed to facilitate the disclosed restart technique. | 03-26-2009 |
| 20090094191 | EXPLOITING EXECUTION FEEDBACK FOR OPTIMIZING CHOICE OF ACCESS METHODS - A proactive monitoring mechanism for correcting the choice of access methods (available query plans) for a given query, based on execution feedback from the same query.

| 20110295833 | Framework for Testing Query Transformation Rules - Described is a test framework for testing transformation rules of query optimizers. Rule patterns obtained as tree structures from a query optimizer are used to generate queries that are used to test the rule optimizer's transformation rules. The test framework tracks which rules are exercised for each query, and also determines the correctness of the transformation rule by comparing the results of the query processing with the rule and without the rule (by turning off the rule). The test framework creates a composite pattern corresponding to two or more rules, such as to test rules in a set (e.g., as pairs). Also described is the efficient execution of a test suite for correctness testing, in which queries of the test suite are selected based upon cost information. | 12-01-2011 |
| 20110313999 | SLICING RELATIONAL QUERIES USING SPOOL OPERATORS - A relational database server may concurrently execute many relational queries, but a complex relational query may cause performance delays in the fulfillment of other relational queries. Instead, the relational database server may generate a query plan for the relational query, and may endeavor to partition the relational query between a spool operator and a scan operator into two or more query slices, where each query slice may be executed within a query slice threshold. Many alternative candidate query plans may be considered, such as inserting spool and scan operators after various operators and parameterizing operators in order to partition the records of a relation into two or more ranges based on an attribute of the relation. A large search space of candidate query plans may be reviewed in order to select a query plan that respects the query slice threshold while efficiently executing the logic of the relational query. | 12-22-2011 |
