despin control electronics
It is presented the localized technical scheme, circuit structure and principles for the cooling fan of control electronics for Guangzhou metro line 1 vehicles.
Just fitting sensors into the fuselage presents a problem-the control electronics supporting many desired sensors are bigger than the 70-gram platforms.
But it remains hard to shrink engines, batteries, mechanical actuators and control electronics to the point where they are small and light enough to fly without impairing their performance.
Worldwide communication over many links is possible because of the E-4B's advanced command and control electronics.
Technical challenges remain, including integrating a leakproof backup battery into the device and miniaturising the FREE-D’s control electronics.
