Scaling a Distributed Sensor Array

Technology Description: We present a method for adding a new sensor node to an existing distributed sensor array (DSA) through individual calibration of the new sensor node without having to recalibrate the entire system. Prior solutions for adding a new node to a DSA typically include performing a calibration procedure not only for the new node...

System for Extracting Venous Pulsation and Respiratory Information from Photoplethysmographs

The University of Texas at Dallas presents a technique that addresses the inaccuracy of skin-mounted photoplethysmographic (PPG) biosensor measurements by separating the arterial and venous signals - enabling extraction of other medically-relevant features, including: respiration rate, heart rate, and SpO2. The effective removal of various motion artifacts...

Accurate and Motion-Tolerant Sensing of Arterial and Venous Pulsation for Wearable Photoplethysmographic (PPG) Biosensors

The University of Texas at Dallas presents a real-time, adaptive technique that provides robust signal enhancement against motion artifact for wearable photoplethysmographic (PPG) systems, enabling the reliable extraction of heart rate and oxygen saturation. Despite the benefits of using PPG biosensors, most of the useful information they capture...
