Taewon Han 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).

  • Patent number: 10919047
    Abstract: A personal electrostatic bioaerosol sampler (PEBS) for collecting bioaerosols (from virus to pollen) at high sampling flow rates and for measuring personal exposures to bioaerosols in various occupational environments, particularly at their low concentrations and for extended periods of time, and a method of using same, are disclosed. The PEBS includes a base holder, a charging section, and a collection section. Charging section includes a first member inside a center of charging section configured to be connected to positive or negative high voltage and a second member disposed therearound a midpoint of first member inside charging section configured to be grounded such that a plurality of ions are produced for charging a plurality of incoming particles.
    Type: Grant
    Filed: September 8, 2016
    Date of Patent: February 16, 2021
    Assignee: RUTGERS, THE STATE UNIVERSITY OF NEW JERSEY

  • Patent number: 9333512
    Abstract: An electrostatic screen battery for emission control (ESBEC) system includes a plurality of screens arranged in an alternating manner, so that screens at a first electric potential are interposed with screens at a second electric potential, with an ionizer disposed upstream of the screens, wherein a particulate-containing exhaust stream passing by the ionizer and then through the screens deposits particulates onto the screens. In preferred embodiments the screens have hydrophobic surfaces.
