A far more secure (and more expensive) system has two cylinders in each lock, one for the change key and one for the master key. Master keyed lock systems generally reduce overall security. [2]
Sensitivity time control (STC), also known as swept-gain control, is a system used to attenuate the very strong signals returned from nearby ground clutter targets in the first few range gates of a radar receiver. Without this attenuation, the receiver would routinely saturate due to the strong signals. This is used in air traffic control ...
