Patent number: 8743452Abstract: Metal nanovoids are grown on a stretchable plastic film. The fabrication proceeds by assembling the template of a single layer of close packed silica spheres on a conducting substrate. A conducting layer is then electrochemically grown on top to form a master. An elastomeric precursor is then coated on the master (e.g. by spinning) and is cured before removal. The resulting plastic film is then coated with a thin (e.g. 20 nm) layer of noble metal (e.g. Au, Ag or Cu), to produce a flexible film. Applications for such tuneable structural color would be coating of injection molded artifacts, such as mobile phone covers, car bodies to form an iridescent skin, wall and fascia decorations, loudspeaker coatings, architectural tent coverings, and clothing.Type: GrantFiled: May 22, 2008Date of Patent: June 3, 2014Assignee: Cambridge Enterprise Limited of the Old SchoolsInventors: Jeremy John Baumberg, Phillip Nigel Bartlett, Sumeet Mahajan, Robin Cole

Patent number: 7643416Abstract: An approach for adaptively providing network performance enhancing functions in a secure environment, such as a virtual private network, is disclosed. Traffic, for example, Internet Protocol (IP) packets, is received for transport over an access network (e.g., satellite network). Next, characteristics (e.g., latency) of the access network are determined. A connection (which supports the performance enhancing functions) is selectively established based on the determined characteristics for transport the received packets over the access network. An encrypted tunnel is provided over the established connection to transmit the received packets.Type: GrantFiled: March 12, 2008Date of Patent: January 5, 2010Assignee: Hughes Network Systems, Inc.Inventors: Peter Pardee, John Border, Nigel Bartlett, Douglas Dillon

Patent number: 6503382Abstract: A method of preparing a porous film comprises electrodepositing material from a mixture onto a substrate, the mixture comprising: (I) a source of metal, inorganic oxide, non-oxide semiconductor/conductor or organic polymer, (II) a solvent such as water; and (III) a structure-directing agent such as octaethylene glycol monododecyl ether in an amount sufficient to form an homogeneous lyotropic liquid crystalline phase in the mixture. Electrodepositing the film from a lyotropic liquid phase in this manner provides a porous film having a substantially regular structure and substantially uniform pore size. Following deposition, the porous film may be treated to remove the structure-directing agent.Type: GrantFiled: March 20, 2000Date of Patent: January 7, 2003Assignee: University of SouthamptonInventors: Philip Nigel Bartlett, John Robert Owen, George Simon Attard, Joanne Elliott
