Title: The Innovations of Limei Cheng
Introduction
Limei Cheng is a prominent inventor based in Irvine, California. She has made significant contributions to the field of medical technology, particularly in the areas of fetal monitoring and respiratory assessment. With a total of 3 patents, her work has the potential to improve patient care and outcomes.
Latest Patents
One of Cheng's latest patents focuses on fetal heart rate extraction from maternal abdominal ECG recordings. This innovative system utilizes a computer processor to extract fetal heart rates from maternal signals. It includes sensors attached to the patient to receive abdominal ECG signals, along with a recorder and digitizer to record and digitize these signals. The system features a peak detector to identify candidate peaks in the maternal signal buffer and a signal stacker that divides the maternal signal buffer into snippets. Each snippet contains a candidate peak, and a spatial filter is employed to identify and attenuate maternal QRS signals, ultimately producing a raw fetal ECG signal stored in a buffer. Additionally, a fetal QRS identifier is used to identify peaks in the raw fetal ECG buffer, allowing for the calculation and merging of the fetal heart rate.
Another notable patent by Cheng involves the breath-by-breath reassessment of patient lung parameters to enhance estimation performance in respiratory monitoring. This system includes a breathing cycle detector that identifies breath intervals in airway pressure and flow data. A respiratory parameters estimator and validator asynchronously fits the data to an equation of motion of the lungs, generating estimated respiratory parameters. These parameters are validated using physiological plausibility criteria, ensuring accuracy in the assessment of lung function.
