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: 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: 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: An apparatus for particulate matter (PM) measurement includes a first light source to generate a first light beam and a second light source disposed at a first distance from the first light source to generate a second light beam in parallel to the first light beam to illuminate a PM. The apparatus further includes a first light detector to measure a first timing corresponding to a first self-mixing signal resulting from a reflection and/or back-scattering of the first light beam from a PM, and a second light detector to measure a second timing corresponding to a second self-mixing signal resulting from a reflection and/or back-scattering of the second light beam from the PM. A processor can determine a first velocity of the PM based on a spatial separation between centers of the first light beam and the second light beam and a temporal separation between the first timing and the second timing.

Abstract: Various sensors, including particulate matter sensors, are described. One particulate matter sensor includes a self-mixing interferometry sensor and a set of one or more optical elements. The set of one or more optical elements is positioned to receive an optical emission of the self-mixing interferometry sensor, split the optical emission into multiple beams, and direct each beam of the multiple beams in a different direction. The self-mixing interferometry sensor is configured to generate particle speed information for particles passing through respective measurement regions of the multiple beams.

Abstract: An environmental sensor may include a heat source that heats a metal oxide sensing material. Electrodes may be formed in the metal oxide sensing material that measure the resistance of the metal oxide sensing material to determine the concentration of various gases. The environmental sensor may include an infrared light source that emits infrared light at a given wavelength. An infrared detector and band-pass filter may be used to detect the concentration of a particular gas such as carbon dioxide. In order to reduce power consumption, a heater may act as both the heat source for the metal oxide sensing material and the infrared light source for the infrared detector. The metal oxide sensing material, heater, and infrared detector may be formed in the same enclosure. The enclosure may have an opening that is aligned with an opening in an electronic device housing.
