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...

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...

Virtual Body-Weight Support via Lower-Limb Exoskeleton

Summary:This is a novel control system for powered lower-limb exoskeletons (or orthoses) that provides body-weight support (BWS) for people who have sustained a stroke and other neurological injury. Patients are provided with BWS during conventional gait retraining to help them produce the coordinated muscle activities needed for walking. Although current...

Coherence Diversity in Frequency and Time

The University of Texas at Dallas is seeking companies interested in commercializing a diversity scheme for wireless networks, called coherence diversity, which provides a novel source of gain that is distinct from other kinds of diversity. As individual links in a wireless network often experience unequal fading coherence times and coherence bandwidths...

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...

Spectrum-Agile Massive MIMO System and Capacity Adaptation Between Uplink and Downlink

Massive MIMO is a potential candidate for next-generation wireless communication, such as for 5G. Massive MIMO uses a large number of base station (BS) antennas to potentially allow for orders of magnitude improvement in spectral and energy efficiency. Existing Massive MIMO literature views that such technology with large number of beams (large number...

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...
