The proposed Phase II program will optimize the design and manufacturing process of a compliant brush shroud casing. Recent tests at Wright Laboratories with staged brush seals have demonstrated significantly increased blade to shroud rub tolerance of acompliant casing. Phase I of the program is expected to demonstrate the feasibility of two innovative brush shroud designs with lower cost and we ...

DESCRIPTION (Provided by Applicant): A use has recently been proposed for hyperpolarized noble gases as an MIRI contrast enhancer for e.g. MRJ of the lungs and other vacuous spaces. In all applications using hyperpolarized gases, it is important to measure its polarization. This is especially the case for hyperpolarized gases delivered from a central facility where ...

Stochastic resonance (SR) is a counterintuitive phenomenon in which slight amounts of noise imparted to a system actually increase its sensitivity to weak stimuli. SR has been shown to produce a demonstrable effect in human sensory cells. In both healthy young and clinical subjects - elderly, diabetics, and stroke sufferers - a notable increase in tactile and proprioceptive sensitivity is seen whe ...

Stochastic resonance (SR), a counterintuitive phenomenon in which slight amounts of environmental noise actually increase the discernability of signals or stimuli, produces a demonstrable effect in human sensory cells. In both healthy young and clinical subjects- elderly, diabetics, and stroke sufferers-a significant increase in tactile and proprioceptive sensitivity is noted when electrical or me ...

DESCRIPTION (Verbatim from the Applicant's Abstract): We propose to continue to develop and test a self-contained light delivery device for use in photodynamic therapy (PDT) for Barrett's esophagus. This device employs distally located semiconductor lasers at the end of a thin coaxial cable inserted into a balloon catheter. In Phase I, we successfully developed prototype un ...

DESCRIPTION (Applicant's Abstract): The Phase II effort is the continuation of the development of a robotic bi-manual therapy machine for use in stroke rehabilitation. The robotic therapy device proposed here, called ARCHIME for the purposes of this proposal, has the potential to improve rehabilitation outcomes significantly for individuals who have upper limb i ...
