Publication number: 20140301381Abstract: A wireless communication device can include a processor to operate multiple virtual network interfaces that communicate simultaneously over a common wireless physical interface with different wireless networks. A first virtual network interface can be an infrastructure virtual interface to communicate over a first infrastructure network, and a second virtual network interfaces can be an ad-hoc interface to communicate over a second ad-hoc network. Another virtual network interfaces can be a Station (STA) infrastructure interface to communicate with an Access Point (AP) over a first infrastructure wireless network, and another virtual network interface can be a AP infrastructure interface to communicate with a STA over a second infrastructure wireless network. Another virtual network interface can be a Wireless Distribution System (WDS) interface to allow the AP infrastructure interface to communicate with another Access Point.Type: ApplicationFiled: May 29, 2014Publication date: October 9, 2014Applicant: SRI INTERNATIONALInventor: David Gurevich

Patent number: 8744516Abstract: A Generic Client (GC) operates multiple virtual network interfaces that communicate simultaneously to different networks. Each virtual interface is capable of independent communication over an associated network through the same physical interface. In one implementation, the GC provides simultaneous communication with both infrastructure and ad-hoc networks in compliance with the IEEE 802.11 protocol. The GC provides these dual modes of operation by instantiating different infrastructure and ad-hoc virtual interfaces.Type: GrantFiled: December 16, 2004Date of Patent: June 3, 2014Assignee: SRI InternationalInventor: David Gurevich

Patent number: 7814322Abstract: Wireless network devices discover individual mesh nodes and networks of mesh nodes. An association is formed on the basis of peer-to-peer interactions at layer-1, layer-2 and/or higher layers of the Open System Interconnect (OSI) model. In particular, the system uses Beacon, Probe Request, Probe Response, Association Request, Association Response, and Disassociation frames and introduces a new Extensible Mesh Information Element (EMIE) used by mesh nodes to discover, authenticate, and associate with other peer nodes.Type: GrantFiled: May 2, 2006Date of Patent: October 12, 2010Assignee: SRI InternationalInventors: David Gurevich, Jose Gonzalez, Scott Burke

Publication number: 20080035577Abstract: A system and method for treatment of wastewater containing heavy metals, oil products, detergents, phenols, dyes, complexions, complexionates, etc. are described. The system includes a static mixer configured for continuous mixing the wastewater supplied thereto with desired reagents; a feeder of a magnetic powder; at least one coagulator apparatus; at least one oxidizer apparatus; at least one flocculant apparatus; and a magnetic separator configured for applying a magnetic field across an effluent of the wastewater and separating the magnetic sludge from the water. The method includes introducing powder of a ferromagnetic particulate material into the wastewater; adjusting a value of a pH of the wastewater, to form a liquid effluent of the wastewater having an adjusted value of the pH; oxidizing the wastewater having an adjusted value of the pH; flocculating the wastewater, to form flakes of magnetic sludge in water; and separating the magnetic sludge from the water.Type: ApplicationFiled: February 10, 2005Publication date: February 14, 2008Applicant: Uniqkleen-Wastewater Treatment Ltd.Inventors: Edward Brook-Levinson, Yevgenia Dorrokhotov, David Gurevich
