‘Quantum Radio’ May Aid Communications Indoors, Underground, Underwater

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don’t work reliably or even at all, such as indoors, in urban canyons, underwater and underground. The technology may help mariners, soldiers and surveyors, among others.

Unique Method for Orifice Production

To produce accurate, repeatable orifices, all the variables that might influence the Cd Value (Coefficient of Discharge) must be controlled during production. This includes the orifice hole length, edges, surface finishes, roundness and the elimination of all tool marks, burrs, ragged edges and irregularities. If any one of these areas is not perfectly managed, the orifice flow rates will vary from piece to piece thereby making it impossible to predict flow with any accuracy.

New Unmanned Air System Tested on USS Coronado

Researchers from the U.S. Naval Research Laboratory (NRL) successfully tested their Nomad flight vehicle off of USS Coronado (LCS 4) recently. This test demonstrated the Nomad’s upgraded launch and control capabilities as well as a new recovery capability by launching multiple vehicles in quick succession, conducting formation flying operations, and recovering all vehicles sequentially onboard the USS Coronado.
