  • AEROSOL GENERATOR
    Publication number: 20150034086
    Abstract: A sonic aerosol generator is provided that provides a constant concentration of particulate aerosol over a long exposure time to an animal. The concentration of aerosols is maintainable for greater than 30 hours at concentrations of 15 mg/m3 or more. The aerosol generator is used to expose subject to high concentrations of aerosols that more accurately represents the levels that may be seen in a workplace environment.

  • Method and apparatus for cough sound analysis
    Patent number: 6436057
    Abstract: A fast, simple, and reliable method and apparatus for recording cough sounds for diagnosing pulmonary disorders and diseases is provided. This method uses signal analysis techniques to extract quantitative information from recorded cough sound pressure waves. The generated data can be used to diagnose pulmonary disorders and diseases as well as track the effectiveness of treatment regimes over time. The method can also be used to quickly and reliably screen individuals at risk of pulmonary disorders and diseases. A system according to one embodiment includes a mouthpiece connected to the proximal end of a tube. The distal end of the tube is connected to a flexible tube. A microphone is attached to the tube between the distal and proximal ends therof for recording sound pressure waves. A calculated cough sound index (CSI) can be used in diagnostic applications.
