3D subwavelength photonic detector coupled with dielectric resonator antenna
TS-047335 — New IR detector combining a dielectric resonator antenna (DRA) with a semiconductor absorber for improved signal, noise, and speed performance
The three essential characteristics of detectors are signal, noise, and speed. There are inherent trade-offs in these three figures of merit and various applications emphasize one or more characteristics. The primary limitation for infrared detectors and imagers is the limit on the achievable sign…

Fast and Efficient Cross Band Wireless Channel Prediction Using Machine Learning
TS-047296 — A neural network that utilizes a simple and efficient single antenna optimization framework
Systems that use different frequency bands for uplink and downlink communication often need feedback between the clients to exchange band-specific channel information. The current state-of-the-art approach predicts the downlink channel based on the uplink channel by identifying certain variables u…

Novel Phosphors for Solid-State Lighting Applications
TS-046581 — Novel halide perovskite phosphor that, when paired with blue LED light, creates warm white light without the need for high temperature ceramics in its production and does not contain rare-earth elements. It has several applications including solid-state lighting and white LEDs. The phosphors produce light with a natural appearance and extended excitation spectra.
Phosphors are used in a variety of products and for a variety of reasons. Halide perovskite phosphors, a specific type of phosphor, can be combined with light emitting diodes (LED) to create phosphor converted LEDs (pc-LED). The current technology has several shortcomings; deficiency in red and cy…

Quantum Well Design for Red-Emitting InGaN LEDs
TS-042441 — The quantum well design is incorporated within a red-emitting InGaN QW LED, an LED type that usually cannot efficiently emit wavelengths larger than blue/green. The LED can be incorporated into a same-material RGB platform for white LEDs, because the well design increases efficiency and decreases indium composition compared to similar wavelength InGaN LEDs.
Blue-emitting InGaN quantum well (QW) LEDs now have 69% external quantum efficiency, but increasing the emitted-wavelength decreases the efficiency significantly. The inversion asymmetry of the InGaN lattice increases the induced strain, which in turn increases the piezoelectric effect. Charge bui…

Machine-Learning Algorithm for Improved Speech Intelligibility in Noise
TS-042266 — A monaural machine-learning algorithm for classifying time-frequency units in an unknown signal, which results in marked speech-intelligibly improvements in noisy signals.
A primary complaint of hearing-impaired (HI) listeners is poor speech recognition in background noise. This issue can be quite debilitating and persists despite considerable efforts to improve hearing technology. Despite considerable effort, monaural (single-microphone) algorithms capable of incre…

Field Effect Transistor for High Power Millimeter-Wave Applications
TS-042088 — Transistor structure with high breakdown voltage at high frequency operation
A new generation of high throughput, efficient communication networks and sensors can be enabled through the use of millimeter scale wave regimes. However, current semiconductor materials (such as AlGaN/GaN) have a reduction in breakdown voltage as operating frequency increases, which leads to low…

DAtAnchor: A Multi-Layer Data Loss Mitigation System
TS-041846 — An alternative to traditional data security measures. The technology effectively "anchors" the information to one location, allowing for better security and making it harder to compromise access.
Data breaches are a looming risk for organizations that maintain significant repositories of sensitive data. The fundamental reason behind their inability to prevent them is the philosophy behind the current paradigm in data security: prevent all breaches at all times. Towards that end, existing a…

A Generic Plug-in Jack-knife Accident Prevention System for Vehicle-Trailer Path Tracking Control
TS-041598 — A plug-in that predicts semi-truck jack-knifing and prevents it by saturating or overtaking steering control.
There is an increased consumer demand for autonomous vehicles which make driving safer and easier. Maneuvering and parking a semi-truck with a trailor attached is both dangerous and challenging. Autonomous semi-trucks can avoid one of the most prolific driving problems: jack-knifing, when a revers…

Method for Connectorizing Superconducting NbTi Coaxial Cables
TS-040418 — A fast and inexpensive electroplating technique for producing a connector attachment matching the structural and electrical properties of standard coaxial cables for cryogenic applications.
Experiments performed at cryogenic temperatures much below the 4.2 K of liquid helium frequently require superconducting coaxial cables to efficiently transmit high frequency signals while minimizing heat transfer to the experiment’s cold stage. These cables are most often made of niobium-ti…
