Abstract: According to some aspects of the subject technology, an apparatus includes a first electrode, a second electrode and a dielectric membrane disposed between the first electrode and the second electrode. The first electrode and the second electrode include a number of pores within a region of an input port of the apparatus. The first electrode, the second electrode and the dielectric membrane form a capacitor that is configured to enable detection of occlusion of the input port by water.

Abstract: Aspects of the subject technology relate to electronic devices with intelligent barometric vents. An intelligent barometric vent may provide a moisture-resistant opening between an environment external to a housing of the device and an internal cavity within the housing. The moisture-resistant opening may include a moisture-resistant cover over the opening, the cover having a cover-integrated sensor to detect occlusions of the opening. The device may also include occlusion mitigation components within the housing that operate, responsive to a detected occlusion, to at least partially remove the occlusion.

Abstract: A portable communication device may include a gas sensor enclosed in an enclosure, a port to allow flow of air into and out of the enclosure, and a light source disposed on an internal surface of the enclosure. The light source is operable to facilitate generation of ozone gas within the enclosure. The enclosure may contain a heating element that allows baseline calibration of the gas sensor by thermally decomposing ozone gas molecules. The gas sensor includes a miniature gas sensor such as a metal-oxide (MOX) gas sensor.
