This project develops a wearable/portable robotic device, IntelliStretch, to perform therapeuticrehabilitation of the arm with the following three integrated steps: (1) stretching a spastic/stiff jointto its extreme position under intelligent control to loosen the stiff joint, (2) voluntary movement training using virtual reality games interfaced with assistance/resistance control when needed, and ...

One of the most important problems encountered in an electromagnetic environment is that of providing compatibility between radiating and receiving RF equipment within the environment. This problem is a type of EMI and the goal of RF system designers and analysts is to achieve EMC where no interference problems exist. We propose to develop a software tool named Electromagnetic Interference Toolki ...

"This SBIR Phase II Proposal seeks to develop the physics-basedfault tolerant technology for sensor networks shown to befeasible in the SBIR Phase I study in response to topic N01-080, "Fault Location in an Intelligent Open Sensor Network." Theproposed approach considers that for Conditional-BasedMaintenance purposes an entire ship can be classified as ahierarchy of subsystems, which conceptually ...

Environmental degradation of aerospace turbine components is a major concern for aircraft and power generation systems, and various surface treatments are utilized to extend the lifetimes of these critical components. This Phase II project is targeted toward extending the durability of thermal barrier coatings (TBCs) on hot section turbine components. TBCs are highly susceptible to degradation b ...

The United States Navy (USN) uses a number of high strength steels, primarily AerMet100, in demanding landing gear structural applications. Unfortunately AerMet100 is expensive and, despite impressive mechanical properties, is subject to stress corrosion cracking (SCC) and requires plating operations for corrosion resistance. In a recently completed Phase I SBIR program QuesTek Innovations applied ...

The objective in this exploratory development is to design, fabricate and test a dual-mode radome for a high speed missile application. Performance, cost and ease of manufacturing will be emphasized. Radome models will be produced to be as close toflight hardware as practical. The use of an insert to provide performance enhancements will be incorporated into the design.

"The success or failure of military operations increasingly depends on situation awareness. Critical to situation awareness is the knowledge of the precise position and heading of enemy weaponry and personnel. There is a need for navigational systemsindependent of external sources and signals that would provide information about the position or movement of Unmanned Air Vehicles (UAV) used to mon ...

Under the Phase I project, we have developed a Polarimetric Imaging System (PIS), integrated it with the 3-D Flash Ladar (FL), and have demonstrated operation of the integrated device: a PLADAR (Polarimetric Ladar). Furthermore, we have performed a detailed study of the ability of the PLADAR system to see parts of a scene that are not visible under intensity-only imaging. We have also shown how ...

This program is intended to advance the state-of-the-art d36 shear mode projector. Phase I of this effort produced a projector which demonstrates promising bandwidth and source level, especially considering its compact size. It is also the first known d36 underwater projector in the history of piezoelectrics. To develop a robust, high power, and broad bandwidth d36 shear mode projector array and b ...

In this project, new liquid crystal materials will be developedto achieve significant improvements in the acosutic detectionsensitivity and transient response of present liquid crystalbased acoustic detectors. The new detectors will be employed inthe underwater acoustic imaging camera, developed in Phase I, toproduce images of mine-like targets with high image quality,large dynamic range and adeq ...
