Vibration isolation of electronics and/or components
Implementations of the present invention relate to devices, systems, and methods for isolating electronic components from input vibrations. The vibration isolation device may passively isolate the housed electronics from substantially all input vibrations. The vibration isolation device may include elastic members to suspend the electronic components within a support frame such that input vibrations are unable to directly influence the electronic components.
