The nitrogen compounds are brought into contact with a water processing system, forming nitrate on-site. Hydrogen sulfide present in the water processing system is removed, and the production of hydrogen sulfide by sulfate-reducing bacteria (SRB) is eliminated by introducing nitrate into the system, whereby denitrifying microorganisms, using the nitrate, outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide. Nitrate ions generated in the water processing system which contains the denitrifying microorganisms can enhance oil recovery by means of microbial enhanced oil recovery mechanisms. Further, the electric plasma arc apparatus and methodology eliminate major costs of conventional treatment techniques, including the transportation and storage of nitrate and the need for a continuous supply of natural gas and water. |

An instruction translator translates the macroinstruction into a merge microinstruction that specifies an N-bit first source register, an 8-bit second source register, and an N-bit destination register to receive an N-bit result. The N-bit first source register and the N-bit destination register are the N-bit architected general purpose register. An execution unit receives the merge microinstruction and responsively generates the N-bit result to be subsequently written to the N-bit architected general purpose register even though the macroinstruction only instructs the microprocessor to write the 8-bit result into the lower 8 bits of the N-bit architected general purpose register. Specifically, the execution unit directs the 8-bit result into the lower 8 bits of the N-bit result and directs the upper N-8 bits of the N-bit first source register into corresponding upper N-8 bits of the N-bit result. |

Intelligent switching of client packets among a group of servers
The content-aware application switch and methods thereof intelligently switch client packets to one server among a group of servers in a server farm. The switch uses Layer 7 or application content parsed from a packet to help select the server and to schedule the transmitting of the packet to the server. This enables refined load-balancing and Quality of-Service control tailored to the application being switched. In another aspect of the invention, a slow-start server selection method assigned an initially boosted server load metric to a server newly added to the group of servers under load balancing. This alleviates the problem of the new server being swamped initially due to a very low load metric compared to that of others. In yet another aspect of the invention, a switching method dependent on Layer 7 content avoids delayed binding in a new TCP session. Layer 7 content is not available during the initial handshaking phase of a new TCP session. The method uses the Layer 7 content from a previous session as an estimate to help select the server and uses a default priority to scheduling the transmitting of the handshaking packets. Updated Layer 7 content available after the handshaking phase is then used to reset the priority for the transmit schedule and becomes available for use in load balancing of the next TCP session. |

System and method for maintaining timing of synchronization messages over a reverse link of a CDMA wireless communication system
A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase, time and power synchronism while maintaining optimal timing control over synchronization messages. This in turn allows fast acquisition of additional reverse link capacity as needed by allocating additional orthogonal codes within the same code phase and by varying the spreading factor of the codes, as well as by adding additional code phases. |

Packet loss prevention during handoff using packet copy-and-forward
The present invention relates to the handing off without packet loss, from a mobile device traveling from a current point of attachment to a new point of attachment, by providing a copy and forward module in association with the current point of attachment. The copy and forward module copies and stores packets that are being transmitted to a mobile node while the mobile node is in transition from the current point of attachment to the new point of attachment. The copy and forward module maintains a list of addresses as the last known contact addresses of the mobile node, and the mobile node's initial copy request contains an initial contact address of the mobile node. Subsequent copy requests are used to add or delete addresses to the list, and carry a per-address flag to indicate whether the address is to be added or deleted from the list. |

System and method for frame selection in IP-based CDMA network
A wireless telephone without IP capability nonetheless communicates with an infrastructure that uses IP. Virtual IP endpoints, such as Base Stations (BTS), not only communicate with the infrastructure using IP and with the telephone using over-the-air protocol, such as Code Division Multiple Access (CDMA), but one of the endpoints also selects the best frame over a call received by multiple endpoints, alleviating the need for a Base Station Controller (BSC) in the infrastructure. A handoff assist entity causes frame selection to be transferred to a second BTS in accordance with a handoff algorithm. |
