Abstract: A method and system involves vacuum sealing a semi-enclosure at room temperature without requiring mechanical actions within the vacuum chamber. The semi-enclosure has an inlet channel that extends inwardly into the vacuum chamber from an exterior opening (entryway) into the semi-enclosure. An uncured entryway vacuum sealant is provided at the entryway for the semi-enclosure. A vacuum is established in the vacuum chamber until the vacuum pressure reaches a desired vacuum pressure that causes the uncured entryway sealant to be provided to the entryway for the semi-enclosure. The uncured entryway vacuum sealant is cured under vacuum pressure in the semi-enclosure in the vacuum chamber.

Abstract: A device includes two electrically isolated metalized posts attached in close proximity to each other on a bendable substrate. When the bendable substrate bends concavely with respect to the surface onto which the posts are mounted, the distance between the tops of the two posts decreases. At a fixed bending curvature, the two posts will meet and complete an electrical circuit. The posts comprise a flexible material so that the meeting of the posts has minimal effect on the spring constant or damping coefficient of the harmonic oscillation.
