Elliot E. Hui 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).

  • Microfluidic oscillator pump utilizing a ring oscillator circuit implemented by pneumatic or hydraulic valves
    Patent number: 9784258
    Abstract: Microfluidic oscillator circuits and pumps for microfluidic devices are provided. The microfluidic pump may include a plurality of fluid valves and a microfluidic oscillator circuit having an oscillation frequency. The fluid valves may be configured to move fluids. Each fluid valve may be connected to a node of the microfluidic oscillator circuit. The pumps may be driven by the oscillator circuits such that fluid movement is accomplished entirely by circuits on a microfluidic chip, without the need for off-chip controls.
    Type: Grant
    Filed: September 17, 2013
    Date of Patent: October 10, 2017
    Assignee: The Regents of The University of California
    Inventors: Elliot E. Hui, Philip N. Duncan, Transon V. Nguyen
