Navy Chooses EM Option
Media outlets indicate that the U.S. Navy will stick to its original decision to install an electromagnetic aircraft launching system (EMALS) on the new Gerald Ford carrier that is slated for delivery by 2015. This decision comes despite a recent cautionary report from the Government Accounting Office (GAO) that design problems and cost overruns could delay delivery of the … [Read more...]
Air Force Looks to Nanotechnology for Shielding
NH-based Nanocomp Technologies, Inc. has won two SBIR (small business innovation research) contracts from the U.S. Air Force. The light weight and conductive nature of CNTs (carbon nanotubes) have made them ideal candidates for aerospace applications although practical applications have been limited. Under the terms of the first SBIR, Nanocomp will continue to develop CNT-based … [Read more...]
Groups Oppose MRI Limits
According to the Institute of Physics (IOP) further pressure has been applied to the European Commission to amend the Physical Agents Directive, which would, if adopted into national legislation, drastically curtail the use of MRI scanners in hospitals and research centers across Europe. Both the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the … [Read more...]
Bypassing Interference Opportunistically
European researchers working on a project funded under the ICT (Information and Communications Technology) strand of the European Union’s Sixth Framework Programme have developed ORACLE (Opportunistic Radio Communications in unlicensed Environments) that would make handsets actively manage how and when they access a network. This pioneering approach promises to minimize … [Read more...]
