090126: Novel Electroactive Polymer-based Flow Sensors for Automotive Systems

Michigan State University’s sensing technology enables potential commercial applications in a broad range of industrial applications where information is needed on a combination of fluid/gas flow rates (e.g., in a line), along with the real-time density/viscosity variation of those fluids or gases. The invention uses electroactive polymer composites...

090024: X-Plant Spinal Fixator

Lumbar fusion surgery is used for a variety of lumbar spine problems. Initially, most lumbar spine problems are treated conservatively. If symptoms persist, some individuals may be candidates for lumbar spine fusion surgery. The goal of such surgery is to relieve pain, numbness, and weakness, to restore nerve function, and to stop or prevent abnormal...

050122: Pneumatic Nano-Probe Tip for Nano-Manipulation and Manufacturing

A major problem with nano-manipulation is holding the target. Due to the lack of micro force/flow feedback, the target is often destroyed during its manipulation. It would be highly desirable to have a means for picking up and releasing nano-objects without the above difficulties. Description The current invention addresses current operational problems...

050034: Improved AFM Manipulation of Nano-Objects

In traditional atomic force microscope (AFM) based nano-manipulation systems, a cantilever is used as the probe tip to manipulate nano-sized objects. Because of the need for good contact with the object, a "pre-loaded" force must be exerted by the cantilever on the object, making it difficult for an operator to "feel" the object or to adjust and...

050026: A Force Sensing Probe for Micromanipulation and Microassembly

A current limitation with existing micro-probe tips is their relatively high degree of bending when encountering objects on surfaces. This significantly limits the ability of micro-probes to manipulate micro-objects. In addition, the sensor can only have a small dynamic range in its bending if it is to maintain high accuracy in manipulating objects. Description The...

040091: Radial Wave Rotor

Traditional attempts to use depressions or pockets to control wave reflection of off-design operation in internal combustion engines undesirably reduce the sensitivity of axial wave rotors to engine speed changes. Nevertheless, there still exists a need to improve the performance and reduce the size of traditional wave rotors to enhance their commercial...

040059: Wave Rotors for Ultra-Micro Gas Turbines

Gas turbine engines are essentially simple devices having only three parts: a compressor, a combustion area, and a turbine. Applications of such engines are well know, for example, in jet engines of aircraft, propulsion systems of tanks, and small industrial power plants. Devices such as wave rotors have been used in an attempt to improve the efficiency...

020015: Microstripline Circuits for Microwave Plasma Discharges

Widely used in a variety of products and processes, plasmas are generated by applying a voltage between electrodes to facilitate gas ionization. The voltage may be static (DC) or varying at a fixed rate that can be in the RF range (<100 KHz) or as high as tens of MHz in frequency. Typical plasmas have a characteristic physical dimension on the...

000002: Higher Efficiency Process for Preparing Clays for Use in Nanocomposites

Polymer-clay nanocomposites are used in such applications as packaging films, containers, automobile trim and injection-molded components. Homostructured mixed ion clays used in such nanocomposites require a relatively slow and complicated process to be prepared. The existing process for preparing homoionic organoclays (a critical component of...
