Title: XI Zhang and Wearable Heart Rate Detection
Introduction
XI Zhang is an inventor associated with Daly City, California, and Oura Health Oy. His patent work includes techniques for detecting heart rate using physiological data collected by a wearable device.
Latest Patents
Zhang is associated with 1 patent, titled “Techniques for Heart Rate Detection.” The patent describes methods, systems, and devices that receive motion and temperature data collected over time by a wearable device. These data are used to assess the quality of conditions for measuring heart rate. When the quality metric and a timer meet specified thresholds, the device samples photoplethysmogram (PPG) data and uses it to determine a heart rate measurement.
Career Highlights
Zhang’s listed patent work connects wearable sensing with adaptive heart rate measurement. The described approach uses motion and temperature information to guide when PPG data is sampled.
Collaborations
Zhang is associated with Oura Health Oy. His listed coworker, Heidi Similä, is a woman.
Conclusion
XI Zhang’s patent work focuses on using wearable-device data to support condition-aware PPG sampling and heart rate detection.
