Abstract: Aspects of the subject technology relate to an apparatus for self-mixing particulate-matter sensing using a vertical-cavity surface-emitting laser (VCSEL) with extrinsic photodiodes. The apparatus includes a dual-emitting light source disposed on a first chip and to generate a first light beam and a second light beam. The first light beam illuminates a particulate matter (PM), and a light detector extrinsic to the first chip measures the second light beam and variations of the second light beam and generates a self-mixing signal. The variations of the second light beam are caused by a back-scattered light resulting from back-scattering of the first light beam from the PM. The light detector is coupled to the dual-emitting light source. The direction of the second light beam is opposite to the direction of the first light beam, and the second light beam is directed to a sensitive area of the light detector.

Abstract: A portable communication device includes an apparatus for environmental sensing. The apparatus includes a housing, one or more environmental sensors and an ozone source. The housing includes one or more ports for allowing air flow between the surrounding environment and a cavity of the housing. The environmental sensors are coupled to the housing and can sense an environmental agent included in the air flow. The ozone source can generate ozone gas within the cavity of the housing to decompose unwanted organic compounds inside the port.

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.

Abstract: A portable communication device includes a first gas sensor, one or more second gas sensors, at least one port and a calibration module. The first gas sensor is disposed on a first hotplate and is enclosed in an enclosure. The one or more second gas sensors are disposed on one or more second hotplates and are also enclosed in the enclosure. The ports can allow flow of air into and out of the enclosure. The second gas sensors are stable gas sensors, which are used by the calibration module to calibrate the first gas sensor.
