Patents by Inventor Tandeep S. Chadha

Tandeep S. Chadha has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Aerosol sensor for performing counting and multiwavelength or multiangle measurement in combination
    Patent number: 11614392
    Abstract: A method and apparatus for particle counting and wavelength or angle performed in combination in order to characterize an aerosol is disclosed. In one example, data regarding particle counting (such as from an optical particle sensor) and data regarding angle or wavelength (such as from an ensemble measurement sensor) may be separately generated, with the separately generated data being analyzed in combination in order to characterize the aerosol. In another example, data regarding particle counting and regarding angle or wavelength may be generated in combination in order to characterize the aerosol.
    Type: Grant
    Filed: December 6, 2019
    Date of Patent: March 28, 2023
    Assignee: Applied Particle Technology, Inc.
    Inventors: Tandeep S. Chadha, Jiaxi Fang, Pratim Biswas
  • Systems and methods for gas cleaning using electrostatic precipitation and photoionization
    Patent number: 11117138
    Abstract: A gas cleaning system includes an inlet receiving a gas, an outlet spaced apart from the inlet, a gas channel defined between the inlet and the outlet to direct the gas from the inlet to the outlet, a photoionizer disposed to emit radiation towards a portion of the gas channel, and a first electrode module. The first electrode module includes a first discharge electrode assembly that generates a corona discharge within the gas channel and a first collection electrode assembly that collects ionized particles from the gas in the gas channel.
