| 20090174045 | Bump Pad Metallurgy Employing An Electrolytic Cu / Electorlytic Ni / Electrolytic Cu Stack - An electroless Cu layer is formed on each side of a packaging substrate containing a core, at least one front metal interconnect layer, and at least one backside metal interconnect layer. A photoresist is applied on both electroless Cu layers and lithographically patterned. First electrolytic Cu portions are formed on exposed surfaces of the electroless Cu layers, followed by formation of electrolytic Ni portions and second electrolytic Cu portions. The electrolytic Ni portions provide enhanced resistance to electromigration, while the second electrolytic Cu portions provide an adhesion layer for a solder mask and serves as an oxidation protection layer. Some of the first electrolytic Cu may be masked by lithographic means to block formation of electrolytic Ni portions and second electrolytic Cu portions thereupon as needed. Optionally, the electrolytic Ni portions may be formed directly on electroless Cu layers. | 07-09-2009 |

| 20090256700 | Wireless Probe System and Method For a Fueling Environment - A fueling environment is equipped with leak detection probes and liquid level probes. Each of the probes is associated with a wireless transceiver. The wireless transceivers send probe data to a site communicator wireless transceiver. To ensure that the site communicator receives the probe data, repeaters are used within the fueling environment. The repeaters receive the probe data, and some period of time after the sensor transceivers stop transmitting, the repeaters retransmit the probe data to the site communicator. The site communicator discards duplicative information and processes the probe data as needed. | 10-15-2009 |

| 20100046391 | APPARATUS AND METHOD FOR NETWORK ANALYSIS - A system for, and method of, extracting information from multiple sessions and in accordance with disparate protocols, and transforming the same into a common language. Packets are collected by packet collectors distributed throughout a network and those packets, and/or metadata relating to those packets, are passed to an aggregator, which is made available via an application program interface to users/applications. | 02-25-2010 |
