Nine U.S. Patents Issued to STC for UNM Technologies in July, August and September

The U.S. Patent & Trademark Office (USPTO) recently issued nine U.S. patents to STC during the months of July, August and September for technologies invented at the University of New Mexico. The patents, issued during STC’s 2020 fiscal 1st quarter, are for a variety of technologies created by researchers in the Departments of Chemistry, Mechanical Engineering, Electrical & Computer Engineering, Civil, Construction & Environmental Engineering, Computer Science, Physics & Astronomy, and the Center for High Technology Materials.

Issued Patent for “Ductile Fiber Reinforced Polymer Plates and Bars Using Mono-Type Fibers”
Patent No. 10,337,186, issue date July 2, 2019

Inventors: Mahmoud Reda Taha, Eslam Mohamed Soliman

The invention provides a fiber reinforced polymer composite having a plurality of layers containing a plurality of fibers. The layers may be configured to maintain predetermined load sharing ratios among the layers at different load levels to produce a gradual load transfer between the different layers during the progressive failure of the composite. The composite is comprised of mono-fibers and the load sharing ratios of the layers have coefficients of variation that are less than 20%.

Issued Patent for “Apparatus and Method for Solar Energy Micro-forecasts for Solar Generation Sources and Utilities”
Patent No. 10,345,486, issue date July 9, 2019

Inventors: Anthony Menicucci, Thomas Caudell, Andrea Mammoli

The invention forecasts solar energy irradiance potential and subsequent photovoltaic output in a region. This includes collecting meteorological data for a given region and then estimating irradiance levels using parameters collected from the meteorological data. Solar energy production is then simulated using the collected meteorological data, estimated irradiance levels, and physical characteristics of a solar generating system in the given region at a predetermined time.

Issued Patent for “Systems and Methods for Detecting Ribosome Inhibition”
Patent No. 10,365,269, issue date July 30, 2019

Inventors:  Charles Melancon, Shijie Huang

This invention is a cell genetically modified to detect ribosome inhibition in the cell and methods involving such a cell. Generally, the genetically-modified cell includes an aminoglycoside-sensitive orthogonal 16S rRNA (O-16S) coding region bearing a mutated anti-Shine-Dalgarno (O-ASD) sequence, a repressor/operator system, and a polynucleotide encoding a detectable reporter under transcriptional control of the repressor/operator system. The repressor/operator system includes a coding region that encodes a transcriptional regulator and has an orthogonal SD (O-SD) sequence complementary to the 16S rRNA O-ASD sequence. The operator sequence, which is repressable by the transcriptional regulator, is operably linked to the polynucleotide encoding a detectable reporter.

Issued Patent for “Reliability Enhancement Methods for Physically Unclonable Function Bitstring Generation”
Patent No. 10,366,253, issue date July 30, 2019
Inventor: James Plusquellic
This invention is currently licensed.

This invention is a Hardware-Embedded Delay Physical Unclonable Function (“HELP PUF”) that leverages entropy by monitoring path stability and measuring path delays from core logic macros. Reliability- and security-enhancing techniques for the HELP PUF reduce bit flip errors during regeneration of the bitstring across environmental variations and improve cryptographic strength along with the corresponding difficulty of carrying out model-building attacks. A voltage-based enrollment process screens unstable paths on normally synthesized (glitchy) functional units and reduces bit flip errors by carrying out enrollment at multiple supply voltages controlled using on-chip voltage regulators.

Issued Patent for “Encapsulated Polymer Nanocomposite for Efficient Crack Repair and Monitoring of Cement, Rock, and Other Brittle Materials”
Patent No. 10,370,305, issue date August 6, 2019

Inventors:  Mahmoud Reda Taha, John Stormont, Edward N. Matteo

This invention concerns compositions and methods of using the same that provide encapsulated polymer nanocomposites for efficient crack repair and monitoring of a cement-substrate interface.

Issued Patent for “3D Printed Miniaturized Quadrifilar Helix Antenna”
Patent No. 10,381,737, issue date August 13, 2019

Inventors:  Youssef Antoine Tawk, Christos G. Christodoulou, Joseph Costantine, Michel Chahoud, Marwan Fadous

This invention provides an antenna miniaturized topology that is based on the implementation of a conductive loading on a quadrifilar helix antenna. This may be achieved by connecting the tip of the four helical arms to end members which may be circular planar conductors. The miniaturization of the antenna may be further enhanced by incorporating a dielectric material in the space between the four arms.

Issued Patent for “System and Methods for Detecting Bots Real Time”
Patent No. 10,389,745, issue date August 20, 2019

Inventors:  Abdullah Mueen, Nikan Chavoshi

This invention is a system and methods for detecting bots in real time by correlating activity between users using a lag-sensitive hashing technique that captures warping-invariant correlation. Correlated users groups in social media may be found that represent bot behavior with thousands of bot accounts detected in a couple of hours.

Issued Patent for “Integrated Bound-Mode Spectral/Angular Sensors”
Patent No. 10,408,673, issue date September 10, 2019

Inventors:  Steven R. J. Brueck, Alexander Neumann, Payman Zarkesh-Ha

This invention is a 2-D sensor array including a semiconductor substrate and a plurality of pixels disposed on the semiconductor substrate. Each pixel includes a coupling region and a junction region, and a slab waveguide structure disposed on the semiconductor substrate and extending from the coupling region to the region. The slab waveguide includes a confinement layer disposed between a first cladding layer and a second cladding layer. The first cladding and the second cladding each have a refractive index that is lower than a refractive index of the confinement layer. Each pixel also includes a coupling structure disposed in the coupling region and within the slab waveguide. The coupling structure includes two materials having different indices of refraction arranged as a grating defined by a grating period. The junction region comprises a p-n junction in communication with electrical contacts for biasing and collection of carriers resulting from absorption of incident radiation.

Issued Patent for “Robust, Compact, Field-able, Tunable Integrated Photonic Device”
Patent No. 10,411,436, issue date September 10, 2019

Inventors:  Steven R. J. Brueck, Sanjay Krishna, Daniel P. Dapkus

This invention is a tunable laser device including a laser structure and a plurality of individually addressable, separated contact stripes disposed on the laser structure. The laser structure includes a substrate, an active portion disposed on the substrate, and a chirped distributed feedback (DFB) grating disposed on the active portion. The active portion includes at least top and bottom contact layers and a gain medium.
