To control structural vibrationeffectively, the semi-activeintelligent control technologyofstructural vibration has been studied by using the MRD in this thesis.
The result is a pair of intelligent, high-fidelity active sound-reduction earplugs that allow natural hearing when sound is safe and provide automatic protection from both loud, sustained music and sudden, loud percussive sounds.
The manufacturers are also developing adaptive cruise control, which can automatically maintain a safe speed and distance from other vehicles, and intelligent speed adaptation, which can, in its most active form, prevent a driver exceeding the speed limit.
