20090013078 | Optimized Signaling Protocol, Including Session Initiation Protocol (SIP), in a Communications Environment - A redacted version of a signaling protocol, such as Session Initiation Protocol (SIP), is used to optimize call session communications between a communications terminal and a proxy server. During a session registration process, the proxy server captures and stores session context data by leveraging the content of the registration messages. With the session context data stored at the proxy server, the messages between the proxy server and the communications terminal may omit some or all of the session context data. For outgoing messages, a proxy server receives a redacted signaling message from the communications terminal, reconstructs a standard signaling message from the redacted signaling message, and forwards the reconstructed message to a recipient. For incoming messages, the proxy server receives a standard signaling message, redacts the standard message to remove some or all of the session context data, and forwards the redacted message to the communications terminal. | 01-08-2009 |
20090137227 | Federated Virtual Network of Communications Services - A federated virtual network enables the creation of a logical network from multiple physical communications networks that each provide one or more communications services. The communications networks register their service capabilities with a network resources register.

If the service requests are authorized, the network resources register maps the requestor's communication device to one or more network services offered by another network. Verifying the authorization may be performed by consulting an independent entity, which thus acts as a gatekeeper for the services. In this way, communications networks can expand their services and coverage by dynamically tapping into other networks' assets, on the fly and on an ad hoc basis (e.g., in case of emergencies, traffic peaks, or whenever additional services are needed). | 05-28-2009 |

20100095447 | TOILET OVERFLOW PREVENTION SYSTEM AND METHOD - A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system. | 04-22-2010 |

An agglomerate is provided which includes a metal salt selected from nickel hydroxide, cobalt hydroxide, mixed nickel-cobalt hydroxide, nickel carbonate, cobalt carbonate, mixed nickel-cobalt carbonate and combinations thereof, a slag making oxide, and a flux additive. An agglomerate is provide which includes a metal oxide selected from nickel oxide and cobalt oxide, and slag, wherein the metal oxide is encapsulated in the slag. | 08-20-2009 |
20090241731 | SYSTEM AND METHOD FOR EXTRACTING BASE METAL VALUES FROM OXIDE ORES - A method for recovering base metal values from oxide ore is provided by the present disclosure. The ore includes a first metal selected from the group consisting at least one of iron and aluminum and a second metal selected from the group consisting of at least one of nickel, cobalt and copper. The method includes the steps of: contacting the oxide ore with hydrogen chloride gas to obtain chlorides of the first and second metals and subjecting at least the first and second metals to pyrohydrolysis at a predetermined temperature to decompose the chlorides of the first metal into oxides. The method also includes the step of mixing the oxides of the first metal and the chlorides of the second metal in an aqueous solution to dissolve the chlorides of the second metal and recovering the dissolved ions of the second metal from the aqueous solution. | 10-01-2009 |
