We propose to develop a critical enhancement to an existing interactive task guidance system, integrating the capability to utilize data from sensors and control actuators. The system will allow caregivers or rehabilitation professionals to incorporate sensors and actuators into a task script in order to detect task state; detect user state; detect environmental context; detect safety risks; or pa ...

Fully autonomous, taskable robots for use in unconstrained environments are still a dream rather than a reality because of a host of problems, including capabilities of existing sensors, effectors, and control/planning software. Indeed, concepts of operations for robot use are tending toward robots collaborating directly with humans, in relationships similar to bomb squad dogs. Fortunately, enough ...

Research is proposed to investigate the feasibility of a path planning module that makes use of time-bounded lattices to avoid potential collisions in dynamic environments. The challenge of planning in a dynamic environment is two-fold. First, tracking and predicting the trajectories of dynamic obstacles (e.g., cars, humans, and aircraft) is very noisy. Second, planning with dynamic obstacles requ ...

This proposal describes the application of a mature nanotechnology-based crack arrest / structural repair technology as a novel crack arrestor tool for high-strength pipelines. The crack arrestor would comprise a thin layer or sleeve of electrodeposited nanocrystalline material applied to the outside of the pipe either in the coating mill during fabrication or in-field during or following constru ...

This proposal describes the application of a mature nanotechnology-based crack arrest/structural repair technology as a novel in-field pipeline repair tool. The repair would be comprised of a thin layer or sleeve of electrodeposited nancrystalline material applied to the damaged region of the pipe in order to utilize the "crack filling" characteristic of the process. The concept proposed has alr ...

Development of new short-wave infrared imaging sensors with signal processing electronics on the same substrate is critical for a number of military and commercial applications. The objective of this research is to develop a new generation of Ge-on-Si p-n heterojunction photodiodes that will culminate in a demonstration of a 64 x 64-pixel infrared imaging array. These photodiodes, whose feas ...

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 ...

In the Open-source microscopic traffic simulation models project, a component based software framework is proposed to re-engineer CORISM data struture and CORISM interface. Under the architecture combing the innovative framework and the legacy CORISM, prototype of the open source traffic flow simulation models will be developed and demonstrated in the Phase I. In addition, areas identified by th ...

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 ...
