High Efficiency LED Designs Using Quantum Well Engineering
TS-057127 — Achieving high efficiency LEDs with green, amber and longer wavelengths using III-nitride/II-IV-nitride heterostructures as the active media.
Although extensive research and development over the past two decades has resulted in close to 100% external quantum efficiency (EQE) of InGaN based blue light emitting devices, efficiency of the longer visible wavelength emitting devices has remained relatively low. Spontaneous polarization origi…

X-Ray Assistive Device for Standardizing the Knee Templating Process
TS-054471 — Knee templating is used as part of the pre-operative planning for knee replacement to determine the best fit for an implant. The current assistive devices used to determine fit are unreliable and inaccurate for proper patient fit. A new device is suggested to overcome these limitations.
Over 600,000 knee replacements are performed per year. As part of the pre-operative planning for surgery, x-ray images are taken to determine the proper fit for the implant. Even with the use of a calibration ball, this knee templating procedure remains inaccurate and unreliable for a number of re…

Method for Preparing High-Energy Electrodes with Controlled Microstructures for Energy-Storage Devices
TS-052586 — A novel method for producing thick electrodes with controlled cracks to facilitate fast ionic transport and improve battery performance.
The Need
Conventional electrodes for Li-ion batteries are prepared as thin layers of 70 to 100 microns to meet the power requirements of automotive applications. However, using thin electrodes compromises the energy densities of battery cells due to increasing weight and volume of inactive componen…

An Optical Fiber-Based Gamma Thermometer with Simple Design and Potential for Adjustable Axial Segmentation
TS-050215 — This invention proposes that an Optical Fiber-Based Gamma-Ray Calorimeter (OFBGC) sensor array can be designed, which does not require the distinct metallic thermal masses that are a part of the Optical Fiber-Based Gamma Thermometer (OFBGT).
As the world continues to grow and industrialize, the need for safe and efficient power is paramount. Currently, in nuclear fission reactors, there are Local Power Range Monitors (LPRM). They are ion chambers that contain fissile material. The electric current between their anode and cathode is mo…

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…

Ultra-Fast Charging Li-ion Battery Anodes
TS-040614 — A novel battery anode designed to overcome the limitations posed on fast charge batteries by graphite anodes. The new anode increases battery life, is more stable during manufacturing, and has improved heat dissipation qualities.
As technology continues to progress, embedding itself in our daily life from our cars to our wrists, an ever-present concern is the need for batteries with the ability to re-charge quickly. Most of these emerging technologies use Li-ion batteries with graphite anodes. Unfortunately, under fast cha…

Permeable Concrete Vessel for Creating Floating Aquatic Habitats
TS-038397 — A durable solution to freshwater ecosystem restoration made from naturally occurring materials.
Many freshwater bodies of the world suffer from the disastrous, interrelated combination of nearby wetland habitat loss, nitrogen loading, and toxic algal blooms. This problem is seen throughout the United States in nutrient heavy storm water ponds, drinking water reservoirs, and the Great Lakes. …

Environmental and Ship Motion Forecasting Program
TS-037401 — A system that will enable prediction of ship motion in order to improve cargo transfer, helicopter landing, and other naval/commercial operations such as those related to offshore platforms or wave energy generation systems.
Instantaneous and predictive information about sea waves is critical to forecast ship motion, which is needed for many applications, such as cargo transfer and helicopter landing at sea. Scientists use radar to obtain this information, but several challenges must be overcome to develop a robust wa…
