Latest Patents

Weitai Qian holds a patent for a groundbreaking technique titled "Transabdominal fetal oximetry without explicit fetal signal extraction." This patent describes a method that employs a deep neural network to estimate fetal blood oxygen saturation without the need for explicit extraction of fetal signals from mixed maternal-fetal photoplethysmogram (PPG) signals. The technique involves receiving multiple channels of PPG signals from photodetectors positioned on the maternal abdomen, which detect transabdominal diffused light from various light sources. The deep neural network processes these signals to directly estimate fetal blood oxygen saturation, enhancing the accuracy and reliability of fetal monitoring.
