20110228705 | WIRELESS MESH NETWORK TRANSIT LINK TOPOLOGY OPTIMIZATION METHOD AND SYSTEM - A method and configuration manager generates a routing topology for a wireless mesh network. The wireless mesh network has a plurality of internal nodes, at least one edge node, and at least one originating device. A plurality of potential routing solutions is determined which contain a plurality of paths through the wireless mesh network from the at least one originating device to the at least one edge node such that data communicated from the at least one originating device reaches the at least one edge node in no more than a predetermined number of hops. Each potential routing solution is based on at least one measured wireless communication parameter between internal nodes. Metric calculations for each potential routing solution are computed to determine a preferred routing solution. The wireless mesh network is configured to route traffic using the preferred routing solution. | 09-22-2011 |

20130022519 | Extraction of Uranium from Wet-Process Phosphoric Acid - A process for the extraction of uranium compounds from wet-process phosphoric acid includes lowering the iron concentration of the wet-process phosphoric acid and reducing the valency of any remaining ferric iron in the wet-process phosphoric acid to ferrous iron, and then extracting uranium compounds from the wet-process phosphoric acid. The process can include separating a side stream from a feed stream of wet-process phosphoric acid, wherein the side stream has a greater concentration of the uranium compounds than the feed stream by filtration. Extracting uranium compounds from the wet-process phosphoric acid can be by ion exchange process or by solvent extraction. | 01-24-2013 |

20090328095 | MANAGING UNDESIRABLE CONTENT IN IP VIDEO BROADCAST TRAFFIC - A method and apparatus are provided for suppressing display of advertisements within a video over IP stream provided by a content provider. Metadata is prepended to advertisements within the stream. When the stream is received by an access aggregation point, the access aggregation point compares the metadata of an advertisement with preset criteria provided by an enterprise subscriber, and suppresses the advertisement if a comparison of the metadata and the preset criteria indicate that the advertisement is undesirable to the enterprise subscriber. The access aggregation point suppresses the advertisement by switching to a second video channel within the stream for the duration of the advertisement. In this way, the access aggregation point can control display of content provider advertisements without manipulating data within the stream, so as to allow the enterprise subscriber to prevent display of undesirable advertisements to endpoints within the enterprise subscriber site such as set-top boxes within hotel rooms. | 12-31-2009 |
