Abstract: A one-way fill valve for use in electronic enclosures is disclosed. The one-way fill valve allows an inert gas to be added to an electronic enclosure without contamination and without excessive leakage. Generally the one-way fill valve includes a membrane layer and a valve layer that restricts flow of gas in one direction but provides significantly less restriction in another direction.

Abstract: The present invention is directed to a seal configured to be placed over an opening in an electronic enclosure. In certain embodiments the seal covers a depression in the surface of the electronic enclosure, wherein the seal is configured to be adhesively secured along its perimeter to the surface of the electronic enclosure. An absorbent-containing filter element integral with the seal is configured to be placed within the depression in the surface of the electronic enclosure. A channel is configured to be in fluid communication through the seal, said channel further in fluid communication with the adsorbent-containing filter element.
