Latest Patents

Hyejung Kim holds two patents related to the acquisition of biopotential signals. The first patent is titled "System and method for acquisition of biopotential signals with motion artifact reduction." This invention includes an analog readout unit that receives an analog biopotential signal from electrodes attached to a body. It extracts both an analog measured biopotential signal and an analog reference signal. The system features an ADC unit that provides a digital version of these signals and a digital filter unit that calculates a digital motion artifact estimate based on the measured signals.

The second patent, "System and method for acquisition of biopotential signals with motion artifact reduction in real time operation," describes a similar biopotential signal acquisition system. It comprises an analog readout unit, an ADC unit, and two digital filter units. The first digital filter unit employs a cascaded integrator-comb filter to provide a filtered version of the measured signals, while the second digital filter unit calculates a digital motion artifact estimate based on the filtered signals.
