Title: Unsoo Ha: Innovator in Contactless Sensing Technologies

Introduction

Unsoo Ha is a prominent inventor based in Cambridge, MA, known for his contributions to the field of contactless sensing technologies. With a total of three patents to his name, he has made significant advancements that enhance the understanding and monitoring of cardiac activities and the analysis of closed container contents.

Latest Patents

One of his latest patents is titled "Contactless Seismocardiography." This innovative technology features a contactless sensor that includes a cardiac beamformer, a wireless-to-seismocardiogram translator, and an automatic labeler. The cardiac beamformer determines at least one beam for receiving wireless signals generated based on the movement of a heart. The wireless-to-seismocardiogram translator employs a convolutional neural network to transform time-series data detected from the beam into a seismocardiogram. Additionally, the automatic labeler identifies and labels micro-cardiac events in the time-series data.

Another notable patent is "Methods and Apparatus for Radio Frequency Sensing in Diverse Environments." This system can sense the contents of a closed container by analyzing a wireless signal that reflects from an RFID tag on the outside of the container. The frequency response of the tag's antenna is influenced by the relative permittivity of the contents and the tag's environment. The system calculates channel estimates and ratios, which are then processed through a variational autoencoder to generate synthetic data for anomaly detection and classification of the container's contents.
