  • Publication number: 20170129796
    Abstract: Fluid desalination systems that include an FO reactor and an electrodeionization reactor with improved membranes and solvents, and a method of using such systems, are provided. A fluid having a first salt concentration is directed to the FO reactor, which uses a solute to draw salt away from the fluid across a membrane into the solute, where the electrodeionization reactor is salinized solute fluid and (i) generate substantially desalinated fluid and (ii) regenerate the solute for return to the forward osmosis reactor. The electrodeionization reactor is configured to draw positive and negative ions of the solute across cationic and anionic membranes, respectively, by applying a voltage across electrodes sandwiching the cationic and anionic membranes. In some cases, the cationic and anionic membranes are porous gelled polymer electrolyte membranes, wherein a saturated solution of the salinized solute fluid is absorbed.

  • Patent number: 8821731
    Abstract: A method is provided of regenerating solvents used to remove gaseous contaminants from gaseous mixtures of various compositions with significantly reduced energy required, where one exemplary method includes directing a solution with the solvents and the preferentially absorbed and/or dissolved gaseous contaminants through a filter comprising a membrane having pre-determined diffusion rates so that a substantial portion of the gaseous contaminants pass through the filter, permitting the passage of the gaseous contaminants through the membrane for further processing, and recirculating the separated solvent so that it may be used again to remove new gaseous contaminants. In some cases, it may be desired to permit some of the solvent to pass through the membrane along with the gaseous contaminant.

  • Patent number: 8726338
    Abstract: In general, techniques are described for dynamic threat protection in mobile networks. A network system comprising a network security device and a management system may implement the techniques. The management system includes a network server having a shared database. A mobile device manager (MDM) of the management system receives a report message from a mobile device, specifying a threat to a mobile network. The MDM publishes the threat to the shared database. A network management system (NMS) of the management system receives data from the shared database identifying the threat and generates a security policy that specifies actions to address the threat. The NMS then installs the security policy in the network security device so that the network security device performs the actions of the security policy to address the threat.
