Small scale mechanical testing is often a bottleneck in micro and nanocomposite materials development. The proposed Psylotech system is a miniature universal test system that accommodates rigid materials and soft materials, such as biological tissues and rubber in the form of uniaxially loaded samples. The Psylotech nano/micro/milli Test System (nTS) is the evolution and integration of systems dev ...

Mimosa Acoustics will develop a portable binaural audiological device, based on our successful HearID system. HearID is a clinical system for otoacoustic emission and middle-ear power analysis testing; it is FDA and CE-marked. The new system will have the ability to conduct a variety of audiological tests especially for use in hearing-conservation programs, including: flexible otoacoustic emission ...

In Phase I of this SBIR program, QuesTek successfully demonstrated a novel thermomechanical processing technique to enhance the bending fatigue resistance of Ferrium C64 steel. A systems-engineering approach was followed to identify key microstructure attributes (e.g., nonmetallic inclusions) that control the mean and minimum fatigue resistance of the aforementioned steel. Through carefully devise ...

Detecting light at the single photon level is a fundamental measurement function that is useful in a wide variety of applications, including such diverse fields as biological spectroscopy, laser ranging, and quantum communications. Avalanche photodiode (APD) based single photon detectors (SPDs) are very convenient in that they are small solid state devices that don"t require cryogenic cooling. Si- ...

Bridger Photonics and the University of Arizona will develop a passive multi-band compressive sensor for imaging and object recognition applications. The Army has identified a need for multi-band imagery for intelligence, surveillance and reconnaissance missions among others. Multi-band systems offer enhanced discrimination capability and the ability to perform in adverse conditions (at night, smo ...

One of the most significant issues facing amputees leaving rehabilitation units is the loss of connectivity with peers and caregivers. The new Amputee Virtual Environment Support Space (AVESS) being constructed within Second Life is a great resource enabling social networking between returning amputees and caregivers. Emerging haptic devices and sensors could greatly increase the immersive nature ...

The use of chaotic hybrid systems has been recently demonstrated in for potential noise-resilient matched-filter communications. A first demonstration at low (audio) frequencies using a combination of analog and digital components has been demonstrated. With this proposal, our objective is to devise a"chaos-on-a-chip"system that can exhibit similar features to those in while operating in the range ...

Traumatic brain injury (TBI) occurs when physical trauma causes temporary or permanent neurological damage. In some cases, symptoms can continue and contribute to disability. Dizziness and vertigo are associated with nearly all reported studies of mTBI and are a significant and functionally limiting component of the overall disability. This project has as its aim the development of a portable devi ...

Multimodal Sensory Enrichment Device (SEMD) is a medical device system for the testing and training of static and dynamic postural control of sway in patients with dizziness, balance deficit, and/or movement disorders. SEMD provides vibrotactile, visual, and audio cueing referenced to center of pressure for postural control of small and large movement tasks, limited locomotion, dual tasking, and s ...

A new family of non-precious metal catalysts is proposed for the oxidation of ethylene glycol in an alkaline anion exchange membrane direct ethylene glycol fuel cell (AEM-DEGFC). The new catalysts proposed by Mainstream combine the most desirable characteristics of some already demonstrated catalysts, and are expected to exhibit high stability, minimal poisoning, and the full oxidation of ethylene ...
