In this SBIR effort we will develop a high-power, high-speed photodiode (PD) receiver optimized for operation at 1 micron wavelength based on collaboration with Dr. J.C. Campbells research group at the UVA. Demand of such photonic receiver arose from the urgent need of high performance microwave photonic links that replace the conventional metal cables for better SWaP, immunity to EMI and broader ...

ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

ABSTRACT: After a certain amount of service time, many aircraft components need to be cleaned and the coatings on those parts need to be stripped. Prior to the chemical cleaning and stripping processes, those parts are routinely examined by inspectors to locate the part numbers and find their matches on a list. Such a visual inspection process is not only time consuming, but also prone to human er ...

Due to their high specific strength and light weight properties, polymer matrix composites (PMCs) are increasingly used in a wide variety of military and civilian aircrafts. The mechanical strength of PMCs can be dramatically compromised when such materials are exposed to various heat sources during operation and maintenance. It has been shown that PMCs can lose up to 80% of their mechanical stren ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

Topic Synopsis: Current aircraft disposition tools are not designed to take advantage of predictive prognostic information that will be available on new systems such as the F-35 PHM system or the proposed Maintenance and Monitoring system for the E-2D Hawkeye. The central challenges in this topic are to (1) develop automated reasoner technologies to distill large volumes of PHM data into actionabl ...

A method of utilizing 3D printed molds to produce low cost metal parts for obsolescence, engineering development prototypes, and low rate production is proposed for development and evaluation.This method is capable of producing parts of similar quality to mass production techniques such as green sand and lost wax casting at a fraction of the setup costs for those methods.

In response to Defense Logistics Agencys SBIR for Advanced Manufacturing Technologies, Sentient proposes to develop a life-cycle cost optimization tool based on its DigitalClone-ComponentTM (DCC) modeling technology.This tool will enable users to better understand the tradeoffs between manufacturing cost and performance/durability of the resultant components. This is particularly attractive for lo ...
