Laser Technology Inc. (LTI) proposes a Phase II SBIR research project to further develop a Compact Shearography System, Analysis Method and Software for micro-crack detection in concrete. There is an urgent need to detect and characterize fine cracks in concrete that form because of various damage mechanisms including alkali-silicate reaction, delayed ettringite formation or frost damage. Fine s ...

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 ...

During Phase 1 of the project, Sharma & Associates, Inc. developed a concept for high speed freight truck intended for 70-ton, regular freight and bi-modal operation, at speeds up to 150 mph. The truck uses a rigid frame and an indpendent, compliant, primary suspension for its basic architecture. Constant contact side-bearings and yaw dampers were also added to improve dynamic performance. Vehi ...

Development of the basic EMAT based transverse rail defect detector has progressed toward finished form, as envisioned in the original solicitation. This modification is intended to produce a demonstratable version of a 2-rail detection system with automated signal interpertation. The objectives of this work are to: a. Further develop the system into a functioning 2-rail detection system, as ori ...
