First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising: a first chamber; a sensor disposed in the first chamber; a second chamber adjacent the first chamber; a filter permitting airflow between the first and second chambers; a chimney connected to the filter and disposed in the second chamber; and a fan positioned to circulate air from the first chamber to the second chamber. 2. The apparatus of claim 1 , wherein the chimney includes an opening spaced from the filter and spaced from walls of the second chamber. 3. The apparatus of claim 1 , wherein the chimney defines an axis, and the fan is disposed in the second chamber on the axis. 4. The apparatus of claim 3 , wherein the fan is spaced from the chimney. 5. The apparatus of claim 1 , wherein the second chamber is sealed from an ambient environment. 6. The apparatus of claim 1 , wherein the second chamber is disposed above the first chamber. 7. The apparatus of claim 1 , wherein the filter includes a microporous semipermeable membrane. 8. The apparatus of claim 1 , wherein the filter is a one-way filter oriented to permit airflow from the first chamber to the second chamber. 9. The apparatus of claim 1 , wherein the filter is a first filter, the apparatus further comprising a second filter permitting airflow between the first and second chambers. 10. The apparatus of claim 9 , wherein the second filter is spaced from the chimney. 11. The apparatus of claim 9 , wherein the fan is a first fan, the apparatus further comprising a second fan positioned to circulate air from the second chamber to the first chamber. 12. The apparatus of claim 11 , wherein the second fan is disposed in the second chamber. 13. The apparatus of claim 9 , wherein the second filter is ring-shaped and extends concentrically around the first filter. 14. The apparatus of claim 9 , wherein the first and second filters each include a microporous semipermeable membrane. 15. The apparatus of claim 9 , wherein the first and second filters are one-way filters, the first filter is oriented to permit airflow from the first chamber to the second chamber, and the second filter is oriented to permit airflow from the second chamber to the first chamber. 16. The apparatus of claim 1 , wherein the second chamber includes an outer wall that is frustum-shaped. 17. The apparatus of claim 16 , wherein the filter is a first filter, the outer wall includes a lower edge, and the apparatus further comprises a second filter extending along the lower edge. 18. The apparatus of claim 16 , wherein the second chamber defines an axis, and the first chamber is cylindrical along the axis. 19. The apparatus of claim 18 , wherein the outer wall includes a lower edge, and the diameter of the lower edge is greater than the diameter of the first chamber. 20. The apparatus of claim 16 , further comprising solar cells disposed on an exterior surface of the outer wall, the solar cells electrically connected to the fan.
