Knocking Sensor and Prevention for Internal Combustion Engine

Executive Summary Effects of knocking in spark-ignition internal combustion engines range from inconsequential such as an annoying noise to completely destructive such as blasting holes through cylinder heads or pistons. With the rise in turbo charged engines, high efficiency engines, and high performance engines in everything from lawnmowers to...

Chemical Efficacy, Environmental Safety, and Operational Design Improvements for the SandSprayer "Spreader Apparatus for Sand Based Formulations" (Patent No. 8,028,928)

Executive SummaryCurrently, as a part of turfgrass installation and maintenance, topdressing sand and active ingredients (fungicide/growth regulators) are applied sequentially, requiring two passes over the turf. Carrying out these processes separately requires additional time to make two identical passes, leads to spray drift when spraying chemicals,...

Quasi-Static Self-Powering, Sensing, and Data Logging

Executive SummarySlowly acting events can be very difficult to sense, especially for self-powered sensors. Most sensors require an external energy source in order to detect the desired property and report results. For some applications however, a self-powered sensor is desirable that uses energy from the object being sensed in order to record the data....

Flexible Hybrid Fastener with Increased Bond Strength and Optimized Sealing Capacity

Executive Summary Fasteners are often installed through holes drilled in individual pieces to be joined. While significant advancements have been made in fasteners over the past several decades, construction techniques such as using composites (including wood, fiberglass, and carbon fiber), in particular, have exposed serious limitations to existing...

Radial Wave Rotor (Wave Disc)

IntroductionTraditional 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...

Novel Electroactive Polymer-based Flow Sensors for Automotive Systems

Description of Technology 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...
