  • Publication number: 20220093842
    Abstract: Aspects of the subject technology relate to an apparatus including a housing, one or more piezoresistive elements and a magnetic actuator. The housing includes a membrane, and the piezoresistive elements are disposed on the membrane to sense a displacement due to a deflection of the membrane. The magnetic actuator is disposed inside a cavity of the housing. The magnetic actuator exerts a repulsive force onto the membrane to reduce the deflection of the membrane.

  • Patent number: 11280774
    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.

  • Patent number: 10928345
    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.

  • Patent number: 10684656
    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.

  • Publication number: 20200103318
    Abstract: A gas-sensing apparatus with gas convection capability includes a gas sensor mounted inside a container, a substrate forming a bottom plate of the container and an actuator. The gas sensor is mounted over a first surface of the substrate internal to the container. The actuator is coupled to a second surface of the substrate external to the container. The actuator can cause convection of a gas within the container by enabling movements of the substrate in response to an activation signal.

  • Patent number: 10436731
    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.

  • Publication number: 20190033243
    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.

  • Publication number: 20190025271
    Abstract: A miniature gas sensing device includes a silicon-based substrate embedded with multiple first heating elements. A number of electrodes are disposed on the silicon-based substrate. A gas-sensing layer covers the electrodes. A porous or mesoporous adsorbent layer selectively filters components of a gas mixture other than a target gas and allows the target gas to reach the gas-sensing layer. The first heating elements are operable to periodically regenerate sensing capabilities of at least the gas-sensing layer.

  • Patent number: 10156553
    Abstract: An electronic device may have input-output devices such as sensors. The sensors may include environmental sensors that make measurements on the environment surrounding the electronic device. The environmental sensors may make measurements such as temperature measurements, humidity measurements, gas composition measurements, and particulate level measurements. A sensor may communicate with external air through a sensor port in an electronic device housing. An electronic device may have a movable member. The movable member may be moved in response to motion of the electronic device when handled by user or motion of a button or other movable member that is actuated by the user. As the movable member moves, the movable member may create enhanced airflow through the sensor port. This may refresh the air adjacent to an environmental sensor and enhance sensor response time.
