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...

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...

Efficient & Broadband Even-Order Harmonic Multiplication in Standard CMOS

A novel technique to realize highly-efficient passive multipliers in a standard CMOS process is demonstrated to efficiently generate even-order harmonics while simultaneously suppressing odd-order harmonics over broad-bandwidths. This is achieved by improving the cutoff frequency (fT) well beyond a THz. The higher fT combined with proposed nonlinearity...
