  • Publication number: 20200181900
    Abstract: A long-span structure engaged with a plurality of first and second transportation devices for moving the long span structure. The transportation devices travel along parallel, longitudinally-oriented first and second tracks; moving the structure between a first position and a second position. A first region of the structure is fixed to each first transportation device. A second region of the structure is secured to each second transportation device via a bearing assembly. The first and second regions of the structure are laterally spaced apart. When the long-span structure thermally expands or contracts, a slider plate of each bearing assembly moves laterally relative to the rest of the bearing assembly. Growth of the structure in a predictable direction is forced by keeping the first region thereof fixed against lateral movement with the first transportation devices and allowing movement of the second region thereof via the bearing assemblies on the second transportation devices.

  • Patent number: 10637424
    Abstract: Systems and methods for processing information present in a digital audio stream to obtain a measure of gain of an analog-to-digital converter (ADC) preamplifier are disclosed. In one implementation, a method of processing information present in a digitally sampled stream to obtain a measure of ADC preamplifier gain used to digitize the output of a known transducer comprises transforming time-domain digital samples into the frequency domain through use of a discrete Fourier transform (DFT), and using knowledge of the maximum effective frequency associated with the frequency response of the transducer to process frequency-domain data to obtain a measure of the gain of the ADC preamplifier.

  • Publication number: 20200054558
    Abstract: An aerosol preparation assembly includes an entrainment chamber defining an entrainment volume. The entrainment chamber includes a gas inlet port, an aerosol inlet port and an outlet port. The entrainment chamber is configured such that a velocity of a flow of a gas within the entrainment volume is less than a velocity of the flow of the gas within the gas inlet port. The entrainment chamber is configured such that at least a portion of inlet aerosol is entrained into the flow of the gas within the entrainment volume to produce an entrained aerosol flow at the outlet port. The particle selection chamber is configured to receive the entrained aerosol flow and produce an outlet aerosol flow. The particle selection chamber and nozzle are collectively configured such that a volumetric median diameter of the outlet aerosol flow is less than a volumetric median diameter of the inlet aerosol.

  • Patent number: 10382039
    Abstract: A process is disclosed for using microsensors elements embedded in or on articles for detecting target chemical and/or target environmental conditions of interest, including materials hazardous to human health and/or associated with illegal activity. The microsensor elements can be fabricated on a single semiconductor chip, and can be made indetectable to facilitate secure surveillance of potentially illegal activities.

  • Patent number: 10343842
    Abstract: Systems and methods for facilitating hygienic storage and disposal of waste packages such as used disposable diapers include a housing, a lid, and a bag unit having a bag frame and an attached single use flexible bag. The flexible bag is pleated and larger in cross-section at a lower portion than it is at the connection to the bag frame. The bag frame is releasably mounted to the housing so that it will not rotate. The lower portion of the flexible bag is positioned in a storage chamber of the housing that is shaped so as to align and center the bag. A rotatable member having radially extending flexible fingers is engaged with an intermediate portion of the bag. When the lid is closed, the rotatable member will twist the intermediate portion of the bag, sealing odors in the lower portion of the bag. A parent or caregiver will push the waste package through the resistance of the twisted intermediate portion into the lower portion of the bag, and close the lid to re-seal the twisted portion.
