Patents by Inventor Kye-Shin Lee

Kye-Shin Lee 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: 9851337
    Abstract: The present invention is directed to a water condition monitoring device and related methods of use that significantly reduce the cost of the water condition monitoring devices by replacing the expensive and bulky multiple sensor electrodes of currently available devices with a single set of two or three metal electrodes to detect and/or measure such water quality parameters as pH, electric conductivity, temperature, and dissolved oxygen content. A microcontroller activates each sensor one at a time in a continuous loop, processing the sensor signals into near real time water condition data, which may be stored, displayed, or sent to a remote location for storage or display.
    Type: Grant
    Filed: December 8, 2014
    Date of Patent: December 26, 2017
    Assignee: The University of Akron
    Inventors: Kye-Shin Lee, Ajay Mahajan
  • Patent number: 9664717
    Abstract: A tactile sensor includes a flexible medium having electrically conductive strips embedded therein and extending in a first direction, said electrically conductive strips including conductive nanostructures dispersed in a flexible support material, said nanostructures selected from conductive nanowires, carbon nanotubes, and graphene, wherein each electrically conductive strip is connected at each end to an impedance measuring device that measures the impedance across each electrically conductive strip. The electrically conductive strips may be formed on a first layer of the flexible medium by using direct-write technology.

  • Patent number: 7564389
    Abstract: A discrete-time, single-amplifier, second-order, delta-sigma analog-to-digital converter (DT-SADS ADC) and a method of operating the same. The DT-SADS ADC combines switched-capacitor input sampling with switched-capacitor feedback and passive summing junction capacitor integration.

  • Patent number: 5953059
    Abstract: A color signal processing circuit of a camera DSP chip for use with a CCD includes a matrix circuit for converting color signals from the CCD into R-G and B-G signals, a hue/gain controlling circuit for multiplying the R-G signal by a R-hue coefficient and a R-gain coefficient and multiplying the B-G signal by a B-hue coefficient and a B-gain coefficient to form B-Y and R-Y signals by adding the R-G and B-G signals respectively multiplied by respective hue and gain coefficients, a zoom-processing circuit for zoom-processing the B-Y and R-Y signals converted in the hue/gain controlling circuit in a zoom mode, and a frequency converting circuit for synchronizing the B-Y and R-Y signals from the hue/gain controlling circuit or zoom-processed in the zoom-processing circuit with a clock having the frequency four times as large as a color burst signal to provide synchronized signals while loading the color burst signals.
