| 20110177670 | THROUGH SILICON VIA LITHOGRAPHIC ALIGNMENT AND REGISTRATION - A method of manufacturing an integrated circuit structure forms a first opening in a substrate and lines the first opening with a protective liner. The method deposits a material into the first opening and forms a protective material over the substrate. The protective material includes a process control mark and includes a second opening above, and aligned with, the first opening. The method removes the material from the first opening through the second opening in the protective material. The process control mark comprises a recess within the protective material that extends only partially through the protective material, such that portions of the substrate below the process control mark are not affected by the process of removing the material. | 07-21-2011 |
| 20090113042 | METHOD FOR CORRELATING PERIODICALLY AGGREGATED DATA IN DISTRIBUTED SYSTEMS - A computer-implemented method for computing distributed component lag times includes: determining a transaction path for groups of transactions in a plurality of transactions to be processed; determining a distribution of elapsed times from a start of work at each component to an end of work at each component for the plurality of work processing components in the transaction path; determining a distribution of the offsets between the completion of work at the last component of the transaction path and the time of reporting the work at the last component of the transaction path; and combining the distributions of component elapsed times and the distribution of component offsets to calculate the transaction lag for each component in the transaction path. | 04-30-2009 |

| 20090001162 | Enhancing Discovery Services in an EPC Network - Methods and apparatus, including computer program products, implementing and using techniques for providing a discovery service that provides a mapping from an electronic product code to electronic product code information services that include information about an item represented by an electronic product code. The discovery service includes a database containing a list of custodians for the item and a service interface through which electronic product code information services and applications can access the entries in the list. The list includes an entry for each custodian. Each entry includes the electronic product code number, a pointer to an electronic product code information service associated with the custodian, and a trip identifier for the item. The service interface includes several services enabling traceability of the item represented by the electronic product code. Methods and apparatus, including computer program products for using a trip identifier in a discovery service are also described. | 01-01-2009 |
