The present application is directed towards systems and methods for evaluating the integrity of objects through non-destructive means. The objects are evaluated for flaws and defects through the use of applied acoustic energy. The applied acoustic energy creates a dynamic response of the object being evaluated to determine the location of any flaws or defects in the object. During excitation, the flaws and defects in a sample object generate heat at the damaged or defective regions through frictional interactions of the discontinuities. A flaw detection system includes, a plurality of acoustic energy sources to excite an object, a camera to record metrics of the response of the object and a processor configured to receive and analyze the response of the object.

Many of the currently available options for food safety testing are expensive, slow, or limited in the range of threats that can be detected. Sending samples back to testing facilities in the United States is too slow and cumbersome to effectively respond to immediate food safety issues. SPR technology has been well-developed as a tool for molecular analysis, so it is relatively mature in terms of detection methods, chemistry and protocols. However, up until now, SPR devices have been primarily limited to large, expensive, benchtop units that require considerable expertise for operation of the devices. What is needed is the development of inexpensive, field-portable SPR devices that are extremely easy to operate in the field. Additionally, the use of a disposable fluidics card format would greatly enhance ease-of-use and device contamination concerns. Resodyn Corporation has made significant progress in developing SPR biosensors, and proposes to develop a field-portable SPR biosensor as a food safety monitoring device. This sensor would be able to detect the presence of multiple pathogens and/or toxins simultaneously at levels relevant to preventing food-borne illness. In addition to determining the presence of pathogens, specific methods are proposed to assess the viability of the pathogens as well.

The U.S. Navy seeks a proactive approach to reinforce the thin walled corrosion resistant steel (CRES) pipes at the welded joints in order to prevent potential leaks from occurring in situations where joint cracks are generated. Currently, there is no known product available to meet this need. Resodyn Corporation proposes for development a clear, tough, corrosion protective, VOC-free thermoplastic, joint reinforcement coating (JRC) to address the U.S. Navy's need under consideration. The JRC will be capable to strongly adhere to CRES substrates, and will be sprayable in hard-to-reach, confined spaces. The clear thermoplastic component will be primarily based on a strong and affordable thermoplastic polyurethane (TPU) characterized by excellent chemical resistance to hydrocarbon fluids such as JP-5, transmission fluids, motor oils, etc. The resin will be further reinforced with cutting edge anisotropic fillers in amounts that will not hurt transparency. The JRC's "see through" nature will offer the possibility to non-destructively inspect the joint welds periodically through a visual examination. Resodyn Corporation's patented Polymer Thermal Spray (PTS) technology will be employed to deposit the resultant JRC materials starting from precursor materials in the solid state, powdery form. The PTS technology also allows for coating repairment in short periods of time.

ABSTRACT: Resodyn Corporation proposes to develop a portable, cost effective, near-surface residual stress measuring tools based on electromagnetic principles. Resodyn Corporation has patented technology developed for validating cold expanded button head rivet holes.The first application in Phase I is to apply this technology to countersunk cold expanded rivet holes in 7075 aluminum. In Phase II, probes will be developed for all of the common hole sizes of interest to the Air Force, and additional evaluation algorithms will be developed for other alloys such as 2024 aluminum and titanium. At the end of Phase II, field tools will be available for evaluation at Tinker AFB. The proposed work will include custom sensors, proprietary detection circuitry (patent pending), residual stress, strain and cold work studies, and correlating algorithms. Extending the technology to other surface stress processes such as peening on fan and compressor blades is also proposed for Phase II. BENEFIT: An operational need exists for a non-destructive method that can quantify the effectiveness of the cold expanded hole process. When the correct amount of residual stress is induced around a cold expanded rivet hole, fatigue life is enhanced up to 20,000 hours. However, because there is no method to guarantee, 100%, that the correct amount of residual compressive stress was created, the process cannot be given credit in design calculations. It is presently done to provide un-credited safety margin. The proposed validation device for cold expanded holes will provide 100% inspection and thus enable the design credit.

The present application is directed towards systems for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.
