A baseplate in a disk drive suspension system is configured with an integral anvil having a spring-forming edge that coincides with an optimal bend location on a linear flex spring. The ribbons are mounted on pedestals such that the resulting micromechanical structures are substantially symmetrical with respect to a plane along their long axis through the centers of the pedestals and normal to the substrate. For example, a user might not want to be notified of an incoming message that arrives between 10:00 P. A piston, forming an equalization chamber, is connected to the sleeve and to the push rod so that when the piston moves in one direction the sealing member is moved in the opposite direction until camover when both move in the same direction. In certain embodiments, the core may include a plurality of elongated members.
