| 20090090162 | Driver plate for electromagnetic forming of sheet metal - A multi-layer driver plate is disclosed for use in electromagnetic sheet metal forming operations. In one embodiment, the driver plate comprises a first layer characterized by low electrical resistivity and thickness for inducement and application of a suitable electromagnetic forming force, a second layer comprising an elastomeric material for compressing a sheet metal workpiece against a die surface and then regaining its original pre-forming structure, and a third layer interposed between the first layer and the second layer to protect the EMF force providing layer and to provide overall strength and durability to the EMF driver plate. | 04-09-2009 |
| 20100154502 | HIGH VELOCITY FORMING OF MEDICAL DEVICE CASINGS - Methods and devices provide for high velocity forming of medical device casings. The high velocity forming may be produced by creating a pressure wave within a liquid contained by an enclosure. A die and a workpiece adjacent to the die are in the path of the pressure wave within the enclosure and the pressure wave forces the workpiece to conform to the contours of the die. Objects may be adhered to the die to provide for customized contours. Trimming features may be included within the enclosure to trim excess material from a formed workpiece as an integral part of the forming process. Various other features may also be provided within the enclosure including a diffuser to disperse the pressure wave. The workpiece may be of various forms including flat sheet stock. | 06-24-2010 |
| 20110000953 | LOW-TEMPERATURE SPOT IMPACT WELDING DRIVEN WITHOUT CONTACT - A laser, aimed at a flyer plate tab, causes optical energy to be directed at the tab, specifically, at a top surface thereof. Energy impacting the tab accelerates the tab out of an initial bent position, straightening it into an impact with a target sheet. The impact occurs in excess of 100 m/s, resulting in a metallurgical bond between the tab and the target sheet. The laser preferably strikes the top surface in a normal direction, based upon an initial angularity of the tab relative to the target. The laser emission, preferably in the range of 1 to 100 Joules delivered in a microsecond, may be augmented by an ablative layer on the top surface or a transparent covering on the top surface that reacts against the expanding gas from ablative activity on the top surface. The weld is formed without physical contact between the welding device and the tab. | 01-06-2011 |

| 20090276449 | APPARATUS AND METHOD TO TRANSFORM AN EXTRACT TRANSFORM AND LOAD (ETL) TASK INTO A DELTA LOAD TASK - A computer readable storage medium includes executable instructions to support the definition of an Extract Transform and Load (ETL) task. An evaluation of source table structures, source data change indicators, and target table structures is performed. The ETL task is converted to a delta load task in accordance with the evaluation. | 11-05-2009 |

| 20090171959 | APPARATUS AND METHOD FOR PERFORMING TABLE COMPARISONS - A computer readable storage medium includes executable instructions to analyze sort options associated with an input table and a comparison table. It is determined whether a consistent sort can be performed by a first database associated with the input table and a second database associated with the comparison table. A first sort operation is performed on the input table at the first database and a second sort operation is performed on the comparison table at the second database when a consistent sort can be achieved. Sort operations on the input table and the comparison table are executed at a common sort engine when a consistent sort cannot be performed by the first database and the second database. | 07-02-2009 |
