Abstract: Implementations of the present disclosure include an electronic system assembly including a first circuit board including a first set of electronic components. The electronic system assembly includes a first housing containing the first circuit board and a second circuit board including a second set of electronic components. The electronic system assembly further includes a first connector shield having first sidewalls defining a first cavity, the first sidewalls having a first end abutting a first surface of the first circuit board and a second end abutting a second surface of the second circuit board. A first electrical connection extends through the first cavity and electrically coupling the first set of electronic components with the second set of electronic components.

Abstract: Systems and devices for dynamic damping of vibrations are described. Traditional methods of vibration damping often involve trade-offs between stiffness and damping, potentially compromising structural integrity for increased damping. The performance of these damping techniques can also be influenced by the specific profile of the vibrational excitation, presenting challenges in ensuring consistent and reliable damping across different operating conditions. A tunable friction-damping device formed from concentric layers can overcome many of these limitations and presents methods for dynamic damping of vibrations as an alternative solution.
