Multi-layer seals are provided that find advantageous use for reducing leakage of gases between adjacent components of electrochemical devices. The sliding portion comprises a glass window panel and is laterally movable between the upper and lower track members relative to the fixed portion. A side-pin shaft intersects each tumbler pin shaft at a selected angle. The ramp structure optionally includes disc snubber features to reduce disc coning and minimize the axial movement of the ramp structure in response to applied mechanical shocks. A logic delay element may delay transmittal of the first logic signal by the peak detector to compensate for signal delay caused by a filter. The method includes using an inverted lens pin mold in conjunction with a dispense method to create both concave and convex lens masters for making lens stamps containing lens-shaped cavities.
