| 20080207227 | Method and System for Determining a Paging Zone in a Wireless Network - A method of paging a mobile terminal in a radio access network wherein the last known location of a mobile terminal is stored. A location message (also called a Route Update message) is sent from a terminal and received at a sector in the network, identifying the location of the terminal. The network determines a paging zone for that terminal based on configuration information for that sector. The configuration information for each sector typically includes a Route Update radius, and then one or both of a paging zone radius offset, and statically configured sectors. When the terminal needs to be paged, the network then broadcasts a page to the terminal in each sector in the paging zone. Such a system adjusts the paging zone to include sectors which the terminal has a reasonable likelihood of moving to before the network learns that the terminal has moved out of the previously established paging zone. Aspects of the invention provide two complementary methods of adjusting the paging zone: adjusting using a paging zone offset, and adjusting based on a sector list. The paging zone offset adjusts the radius of the paging zone, thereby maintaining a generally circular shape. The sector list adjusts the generally circular paging zone by adding or deleting any sector in any direction, thereby allowing any arbitrary shape to be used for the paging zone. The adjustments to the paging zone achieved by these methods account for such factors as RF coverage, geographic features, congestion, population density and expected rate of movement of terminals between sectors. | 08-28-2008 |

| 20110112195 | Potent and Selective Inhibition by Aurinticarboxylic Acid - The severe acute respiratory syndrome virus (SARS) is a coronavirus that instigated regional epidemics in Canada and several Asian countries in 2003. The newly identified SARS coronavirus (SARS-CoV) can be transmitted among humans and cause severe or even fatal illnesses. As preventive vaccine development takes years to complete and adverse reactions have been reported to some veterinary coronaviral vaccines, anti-viral compounds must be relentlessly pursued. In this study, we analyzed the effect of aurintricarboxylic acid (ATA) on SARS-CoV replication in cell culture, and found that ATA could drastically inhibit SARS-CoV replication, with viral production being more than 1000 fold than that in the untreated control. ATA is also shown to be an effective anti-viral for several other viruses, including West Nile Virus and variola virus. | 05-12-2011 |

| 20100307051 | BIODIESEL PRODUCTION USING ULTRA LOW CATALYST CONCENTRATIONS IN A MEMBRANE REACTOR - A method for producing a fuel or fuel additive comprising providing a reaction mixture comprising oil and an alcohol in an oil-in-alcohol emulsion and a catalyst for converting the oil to the fuel or the fuel additive. The oil and the alcohol are reacted in the presence of the catalyst, at a concentration below that used in a conventional batch process, to produce the fuel or fuel additive. This low level of catalyst reduces the formation of diols and oxidation products that can diminish the quality of the fuel or fuel additive. The fuel or fuel additive produced is continuously removed during the reaction, effectively de-coupling the concentration of catalyst used from the rate of the two phase reaction. | 12-09-2010 |

| 20100061648 | PROTECTION FILTER FOR IMAGE AND VIDEO PROCESSING - A filter includes a conventional filtering block and a protection block. The conventional filtering block receives input values and provides filtered values. The protection block receives filtered values and a group of input values proximate the current input, to ensure that the output is lies within a range computed for the current input. The range is determined by the protection block based on the group of input values proximate the current input. Any algorithm or statistical function may be applied to the group of input values to determine the range. If a filtered value provided by the conventional filtering block is outside the range, then the protection block computes and outputs a value that is within the range. The filter may be used in temporal or spatial filtering of images and video to mitigate artifacts such as motion artifacts and static artifacts. | 03-11-2010 |
