Inductive Charging to Increase EV Market Demand, Says Volvo Study
Volvo Car Group has completed a wireless charging system trial for electric vehicles, concluding that although the technology works and is considered safe, its lack of common standard means it is not yet ready for the consumer market. Inductive charging, which uses an electromagnetic field instead of a cable to transfer energy between two objects, is common in electrical home … [Read more...]
Military Tests Aircraft Injection-Jamming Simulation Software
The SPACE JAM system utilizes an algorithm that injects realistic GPS jamming effects directly into an aircraft's navigation system. (Image: Rebecca Amber / U.S. Air Force)A new jamming simulation project being tested by U.S. Air Force students may lead to better training methods and emergency protocols to combat Global Positioning System (GPS) disruption. Originally designed … [Read more...]
