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...

Hardware and Software System for At-Home Stereognosis Training

Sensory loss of the hand (including impaired proprioception, stereognosis, and tactile sensation) is common after peripheral nerve damage, stroke, spinal cord injury, multiple sclerosis (MS), and other neurological conditions. While sensory retraining therapy has shown some benefits, there is no established method to restore tactile sensation following...

Total Energy Shaping for Task-Invariant Control of Lower-Limb Exoskeletons

We present a total energy shaping control methodology for the development of portable lower-limb assistive exoskeletons and orthotic devices that help reduce the human’s effort and augment natural motion. Current robotic exoskeletons restrict joint motion to pre-defined position trajectories during gait rehabilitation; such methods aim to replicate...

Improved Auto Exposure for Digital and Smartphone Cameras

This invention is an improved auto exposure (AE) method which, unlike existing AE methods, does not make a middle brightness assumption. As a result, this invention allows for better exposed images, in particular in poor lighting conditions such as front/back lit and low light scenes. The developed method has been implemented on a camera platform and...
