Abstract: Aspects of the subject technology relate to electronic devices with pressure sensors. A pressure sensor in a portable electronic device may include an integrated heater or may be co-operated with an external heater for the pressure sensor. The heater may be operated to heat some or all of the pressure sensor for pressure sensor testing, calibration, or temperature-controlled pressure sensing operations.

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: Aspects of the subject technology relate to a device including a pressure sensor to measure a pressure level in a port cavity. A port allows equalization of air pressure between the port cavity and an outside environment. A vent port within the port cavity allows equalization of air pressure between the port cavity and an internal volume of a housing of the device. A tool is used to activate a heat-generating component of the device while the port is obstructed for a predetermined time duration to enable detecting a sealing efficacy of the housing.

Abstract: Aspects of the subject technology relate to an apparatus including one or more transducers, and a pathway for drying the one or more transducers via removal of water from vicinities of the transducers. The pathway includes a tubular structure, and the one or more transducers are disposed at a first opening of the tubular structure. The pathway is to facilitate removal of water via capillary-induced pressure gradient created by a capillary-dense material disposed at a second opening of the tubular structure at a distance from the transducers.

Abstract: Aspects of the subject technology relate to electronic devices with pressure sensors. A pressure sensor may be mounted within a device housing in a pressure sensor cavity at or near an opening in the housing. A barometric vent between a main cavity within the housing and the pressure sensor cavity allows pressure changes in the main cavity to generate airflow through the pressure sensor cavity and out through the opening in the device housing. The generated airflow may clear debris that has occluded the opening in the housing.
