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.

Spring systems for subsea applications and equipment projects for the oil and gas industry are preferably manufactured from composite materials and include at least one pair of springs consisting of a first spring component and a second spring component, mounted so as to offer a first central contact region and double curvature and rebound areas forming a coupling. The pair of springs are thus, self-centering.

Disclosed is a method of manufacturing a final piece including several materials, the final piece being produced at least according to the steps of: inserting an elastomer (5) in at least one insertion cavity (6) of an initial piece (2) so that the elastomer (5) is in contact and fixed with the initial piece (2); then cutting the initial piece (2) in at least two distinct parts (3, 4), so that the at least two distinct parts (3, 4) are fixed together but not in contact with each other, the at least two distinct parts (3, 4) being connected together by the elastomer (5). This may be applied to manufacturing a final piece including several parts, of various natures, connected together.
