    Abstract: An electronic device may include one or more low-noise pressure sensors for measuring air pressure. The electronic device may include wireless communications circuitry for communicating with external devices also having pressure sensors. Pressure data gathered by an external device may be used as reference pressure data for the electronic device. For example, if both devices are located in the same building, both pressure sensors will detect similar pressure fluctuations due to doors opening and closing and temperature-control systems turning on and off. By subtracting the reference pressure data from the pressure data gathered by the electronic device, calibrated pressure data may be obtained and may be used to reliably detect vertical displacement changes of the electronic device. In other scenarios, the pressure data may be compared with the reference pressure data to determine whether the two devices are in the same room.

    Abstract: An electronic device may include a housing and a display in the housing. The display may be used as an anemometer to measure the speed of ambient air in the device's environment. In particular, the display may be monitored by a temperature sensor until it reaches an equilibrium temperature, at which point it may be heated by increasing the brightness of the display or using a separate heater. After heating, a cooling response of the display may be measured, and the ambient air speed may be calculated based on the cooling response of the display. Instead of measuring the air speed using the display, other components, such as a pressure sensor, may be used to measure the air speed by heating the components and measuring a cooling response of the components. Multiple temperature sensors may be incorporated into the device to determine a wind direction in addition to air speed.

    Abstract: A portable communication device includes a transducer enclosed in an enclosure. An opening allows flow of air between the transducer enclosed in the enclosure and a surrounding environment. The enclosure protects the transducer from misreading due to occlusion of environmental aggressors on the transducer. The enclosure is configured to repel the environmental aggressors away from a surface of the transducer and to keep a portion of the opening unclogged to maintain an air flow to the transducer.

    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.
