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: An apparatus of the subject technology includes a membrane, a first circuit and a second circuit. The first circuit includes a number of resistive elements disposed on the membrane to measure a pressure difference. The first circuit has a resistance. The second circuit implements a temperature calibration procedure by utilizing the resistance to measure a temperature used in the temperature calibration procedure.

Abstract: A miniature gas sensing device includes a silicon-based substrate embedded with one or more heating elements. One or more electrodes are disposed on the substrate, and a semiconductor gas sensing layer is deposited over the substrate including over the one or more electrodes. The semiconductor gas sensing layer includes sensing grains forming a porous matrix, and a nanometer-scale barrier oxide layer deposited over the sensing grains. The barrier layer separates gas adsorption from surfaces of the sensing grains, and enables electron tunneling based charge transfer process from the sensing grains to the barrier oxide layer. The barrier oxide layer enhances the sensor stability and promotes signal selectivity by favoring detection of strongly oxidizing and/or reducing gas species over less reactive gas species.

Abstract: A portable communication device includes an apparatus for environmental sensing. The apparatus includes a housing, one or more environmental sensors and an optical 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 optical source can illuminate the cavity of the housing to decompose unwanted organic compounds inside the port.

Abstract: A portable communication device includes one or more miniature sensors to sense one or more environmental gases. A processor is coupled to the miniature sensors and is configured to enhance location detection by determining a sensor signal transition. The sensor signal transition is caused by subsequent exposures of at least one of the miniature sensors to environmental gases of a first air composition and a second air composition. The first air composition and the second air composition are respectively associated with a first location and a second location.

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 miniature gas sensing device includes a silicon-based substrate including an opening. A first membrane is formed over the silicon-based substrate and a first portion of the first membrane covers the opening. A gas sensing layer is formed over a number of electrodes disposed over a first surface of the first portion of the first membrane and one or more heating elements. A permeable enclosure encapsulating the gas sensing layer can maintain thermal energy density over the gas sensing layer at a level sufficient to destroy a target gas to allow measuring a zero baseline.
