  • Publication number: 20210080912
    Abstract: Aspects of the subject technology relate to an apparatus including one or more transducers, and a pathway for drying the one or more transducers via removal of water from vicinities of the transducers. The pathway includes a tubular structure, and the one or more transducers are disposed at a first opening of the tubular structure. The pathway is to facilitate removal of water via capillary-induced pressure gradient created by a capillary-dense material disposed at a second opening of the tubular structure at a distance from the transducers.

  • Patent number: 10837772
    Abstract: Aspects of the subject technology relate to electronic devices with pressure sensors. A pressure sensor may be mounted within a device housing in a pressure sensor cavity at or near an opening in the housing. A barometric vent between a main cavity within the housing and the pressure sensor cavity allows pressure changes in the main cavity to generate airflow through the pressure sensor cavity and out through the opening in the device housing. The generated airflow may clear debris that has occluded the opening in the housing.

  • 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.

  • Patent number: 10462544
    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.

  • Patent number: 10271127
    Abstract: This disclosure describes a speaker assembly suitable for use in a portable electronic device utilizing water resistant ports. The speaker assembly can have an open back that subjects a back volume of the speaker to pressure differentials within a device housing of the portable electronic device. The speaker assembly can utilize a speaker surround having a varying thickness. The varying thickness speaker surround allows the speaker to maintain an acceptable frequency response profile while limiting the travel of the diaphragm it is coupled with. The disclosure also describes how electrically conductive pathways can be integrated within a housing of the speaker assembly.

  • Patent number: 9751116
    Abstract: Apparatus for removing material lining the inside surface of a cylindrical structure, the apparatus comprising: a support for supporting the structure in a horizontal orientation; an elongate horizontal boom for being inserted into the structure; a nozzle assembly connected to the boom member, the nozzle assembly comprising one or more nozzles wherein each nozzle is suitably spaced from the lining to deliver a jet of fluid under pressure to the lining; a conduit in fluid communication with the nozzle assembly suitable for delivering a flow of fluid to each nozzle under sufficient pressure to cut the lining material adjacent the nozzle; and a rotation mechanism cooperating with the support to passively enable the structure to being rotated while supported by the support or to actively impart rotation to the structure while supported by the support, wherein the rotation of the structure is about a central longitudinal axis of the structure.

  • Patent number: 9671300
    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.

  • Patent number: RE44518
    Abstract: This application discloses an automated apparatus for scarifying the interior surface of a pipe or other similar elongated passageway. The apparatus includes a vehicle that propels itself down the inside of the pipe. A scarifying assembly is removably secured to the vehicle and uses arms to reach the walls of the pipe. At the end of each arm there is a fluid nozzle assembly equipped with fluid nozzles. The fluid nozzle assembly rotates or oscillates to scarify the pipe surface. The arms and fluid nozzle assembly interchange with other such scarifying assemblies depending on the shape or type of pipe and the desired scarifying technique. The apparatus is tethered to a source of fluid under pressure and a power source, both of which are located off-board the apparatus at a remote location.
