Title: The Innovative Contributions of Ya-Chi Liu
Introduction
Ya-Chi Liu is a prominent inventor based in Douilou, Taiwan. She has made significant strides in the field of non-contact vital sign detection, contributing to advancements in medical technology. With a total of 3 patents to her name, Liu's work is paving the way for innovative solutions in health monitoring.
Latest Patents
One of Liu's latest patents is focused on random body movement cancellation for non-contact vital sign detection. This method and system aim to cancel the effects of body movement during the detection of vital signs without physical contact. The process begins with a first electromagnetic wave transceiver sending a first electromagnetic signal at a specific frequency to one side of a body, such as a person or animal. Simultaneously, a second electromagnetic wave transceiver sends a second electromagnetic signal at a different frequency to the opposite side of the body. The reflected electromagnetic signals from both transceivers are received, and baseband complex signals are extracted. These signals are then mathematically combined to cancel out any Doppler frequency drift, resulting in a periodic Doppler phase effect that enhances the accuracy of vital sign detection.
