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...]

Microsoft’s Gates Files for EM Patent

 

Microsoft’s Bill Gates is one of the principal applicants on a patent published last week by the U.S. Patent and Trademark Office. The concept underlying this hybrid engine is not software; the device is essentially an electromagnetic combustion engine. Ostensibly, the engine’s mechanical force, created by traditional combustion, would be converted into electrical or … [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...]
