Motor Controls: a Neural-Network
The Problem:
Motor controller technology exists, yet current approaches each have inhibiting flaws (i.e.. standard lookup tables are time-consuming, occupy large memory usage, and have little control accuracy). While driving a car, different speeds translate into torque, and current leading methods convert torque inefficiently.
The Solution:
Utilize...

Method of Forming MoSx Catalysts onto Conductive or Semiconductor Substrates for Alternative Energy
The Problem:
Current technology for methods of forming catalysts on conductive or semiconductive substrates utilizes precious metals such as platinum to catalyze the reaction. This is a very expensive way to complete the reaction. Additionally, current methods are highly energy intensive, which is an undesirable trait.
The Solution:
The technology...

Method to Enhance Photocurrent and Power Conversion Efficiency of PLZT Thin Film Capacitors
The Problem:
Solar cells are widely used and are a great sustainable way to harvest energy. Often the capacitor structures of these solar panels use conventional metal electrodes (aluminum or platinum), however, they still are not incredibly efficient. The power conversion values achieved with these capacitors are not great. Low energy efficiency in...

Minimum-Contact Heat Supports for Metal Additive Manufacturing
The Problem:
Powder-based electron beam additive manufacturing (EBAM) utilizes a high-energy electron beam, as a moving heat source, to melt and fuse metallic powders and produce parts in a layer-wise fashion. If a part has overhang geometry, such as a cantilevered overhang or undercut portion, defects such as curling may occur due to the thermal gradient...

Nano-Manufacturing: Dynamic Sweep-Plow Microcantilever
The Problem:
Current nano-machining technology utilizes only a plowing action for cutting where the tool is forced into the surface to be shaped and uses bending to provide the force to the cutting tip. The current technology only allows for thin grooves and requires an indentation into the surface. There is a need for technology with increased accuracy...

Core-Shell Nanomagnets: Out with Rare-Earth Metals
The Problem:
Many of the permanent magnets currently being made are made of rare-earth metals. These metals have operational temperatures below 150°C. This is problematic for motor applications (i.e., electric motors) that require operational temperatures of at least 160°C, and leads to a loss in the magnetic properties of the metals. Further,...

Layered Heusler Alloys and Methods for the Fabrication and Use Thereof
The Problem:
MRAM currently utilizing ferromagnetic materials does not incorporate Heusler alloys in a superlattice configuration. The absence of this configuration limits the spin polarization which leads to the need for a larger power supply. Additionally, this effectively limits the scalability of the memory.
The Solution:
The novel technology...

Vector Control of Electric Machines and Drives by using Artificial Neural Networks
The Problem:
Traditional methods of using only vector control methods have shown limitations in adapting to varying power supply demand situations – especially if the PMSM is powered by wind or other natural energy sources. In additional, vector control technologies such as proportional-integral-derivative (PID) have shown inability to adequately...

Methods of Making Nanostructured Metal-Organic Frameworks
The Problem:
Traditional synthesis of Metal-Organic Frameworks (MOFs) requires the use of hazardous organic solvents, high pressure, and heat or microwaves. This process, however, lacks a higher degree of control and the MOF crystals that are synthesized appear in a bulk state which is less desirable. Surfactants can be introduced to reduce the size...
