Abstract: Certain exemplary aspects of the present disclosure are directed towards an apparatus including a base deck forming a sealed cavity. A filter coupled to a surface of the base deck within the cavity filters particulate from a flow of gas in the cavity. The recirculation filter including a protrusion extending over a surface of a storage medium within the cavity that diverts gas from a surface of the storage medium toward the filter. A bypass channel, defined by a portion of the cavity and a portion of the filter, in conjunction with the protrusion forms a pressure differential that draws a first portion of the diverted gas through the filter by bypassing the filter with a second portion of the diverted gas.

Abstract: Apparatus and method for mitigating impedance changes in a microactuator conductive joint. In accordance with some embodiments, a microactuating element has a conductive input junction, the junction having dissimilar metals in contact with one another. The microactuating element is adapted to mechanically deform to displace a control object responsive to a micractuation control signal that is applied to the junction. A control circuit applies a bi-directional transition signal to the conductive input junction to reduce an increased impedance of the junction.
