Abstract:
1. An apparatus comprising: a directional membrane comprising a plurality of valves extending through the directional membrane, wherein the plurality of valves allows a fluid to pass through the directional membrane in a first direction and resists fluid passing through the directional membrane in a second direction, wherein the directional membrane comprises an attachment region coupled to a portion of a structure and a suspended region disposed over an opening in the structure, wherein the directional membrane is constructed from a material selected from the group consisting of plastic, rubber, and a polymeric material; a directional flow mechanism that allows a fluid to flow in a third direction and resists fluid flow in a fourth direction, wherein the directional flow mechanism comprises a portion of the structure, wherein a cavity is disposed within the structure, wherein the first direction and the fourth direction are directed away from an interior of the cavity and the second direction and the third direction are directed towards the interior of the cavity; and an oscillation module that induces an oscillation in the directional membrane, the oscillation module comprising
