Better camouflage is needed to hide from new electronic sensors
A team at the University of California, Irvine is designing infrared camouflage by embedding tiny metal flakes into thin sheets of rubber. These sheets can then be incorporated into clothing. … Both designs would add but a trivial amount of weight to military fatigues, notes Alon Gorodetsky, a professor of chemical and biomolecular engineering at Irvine, who leads the project. The technology, he says, could be ready within a few years. Such materials, he adds, might also be used as insulation for the better control of heat flows in electronics.

Building An Alternative to GPS
"There is an urgent need to find an alternative robust and accurate navigation system to GPS," says Zak Kassas, an associate professor [of engineering and ICS] at University of California, Irvine, and Director of US Department Transportation Center for Automated Vehicles Research with Multimodal AssurEd Navigation (CARMEN). "We are over-relying on these systems, despite their known limitations." Fortunately, Kassas and his colleagues have devised a novel substitute for GPS. Read More
