THERE IS SUBSTANTIAL NEED FOR NEW SENSORS WHICH MEASURE ABSOLUTE DISTANCE FOR APPLICATIONS IN ROBOTIC POSITIONING, MACHINE VISION, AUTOMATIC INSPECTION AND GAUGING. WITH ITS ABILITY TO MEASURE NON-CONTINUOUS CHANGES IN POSITION, THE SENSOR COULD PROVIDE FEEDBACK MEASUREMENTS FOR CLOSED LOOP POSITION CONTROL FOR ROBOTS, CMMS AND MACHINE TOOLS. FOR AUTOMATIC INSPECTION, A HIGHLY ACCURATE DISTANCE ME ...

Although global pose is essential for success in certain vehicle missions and tasks, when GPS is denied there is no single technology (source) that can robustly estimate global pose without suffering from one or more failure modes. We propose to design an architecture that provides robustness by integrating automated celestial navigation, registering on-board sensor data to a map (map registration ...

THE GOAL OF THIS RESEARCH IS TO DEVELOP A PROCESSOR WHICH USES TIME-FREQUENCY TRANSFORMS TO EXTRACT THE INSTANTANEOUS FREQUENCY OF A SIGNAL IN REAL TIME. IN THE PROCESSOR, THE SIGNAL WILL BE SPLIT INTO TWO PATHS. IN ONE PATH THE SIGNAL WILL BE DIRECTED TO A DELAY LINE AND THEN TO PROGRAMMABLE FILTERS. IN THE OTHER PATH, THE SIGNAL WILL BE DIRECTED TO OUR TIME-FREQUENCY DETECTOR WHICH WILL MEASURE ...

The increase in extreme weather events over the past several decades has underscored the need for regional planning strategies that will support future preparedness and mitigate climate change impact on local communities across the United States. While existing climate modeling tools for non-researchers support a conceptual understanding of climate change at the global level, they do not address t ...

The Acoustically Synchronized Store Ejection/Release Technology (ASSERT) test process was developed by CRAFT Tech. This research has produced a capability to conduct small scale dynamic drop tests instrumented with stereo-photogrammetry to track store motion and synchronize this with unsteady weapons bay flowfield measurements. An advanced pneumatic ejection system has been developed which support ...

THE NATURAL FREQUENCY OF A MECHANICAL SYSTEM PROVIDES INSIGHT INTO ITS CONDITION. THE DEGREE OF STRESS TO WHICH A SYSTEM IS SUBJECTED IS REFLECTED IN SOUNDS PRODUCED BY THE SYSTEM WHEN EXCITED. IN PARTICULAR, THE MOVEMENT OF A MECHANICAL OR BIOLOGICAL CARDIAC VALVE PROSTHESIS GENERATES AUDIBLE SOUND; THE NATURAL FREQUENCY OF A CORRECTLY FUNCTIONING VALVE DIFFERS FROM THAT OF A FAULTY VALVE. THIS R ...

KCF Technologies in partnership with Lockheed Martin, Inc. proposes a lightweight, low drag, quasi-active noise control system to reduce the acoustic signatures of existing SOF fixed wing aircraft. The proposed solution is based on integrating flow-excited resonators near the blade tips of the propeller, commonly the aircrafts major noise source. The resonators are tuned actively to generate anti- ...

Technology improvements continue to result in massive increases in data collection and repository sizes causing ever increasing big data volumes.Research shows that it is easy to bury users in even small amounts of data when it is presented out of a meaningful context. General representations like data lists put the burden on the user to transform data into meaningful contexts.This results in unne ...

DESCRIPTION provided by applicant In this NIH SBIR Phase II Actuated Medical Inc will finalize and clinically test the andquot Active Fine Gauge Spinal Needle with CSF Sensing to Minimize PDPH and Dura Damage andquot Phase I achieved all Specific Aims and demonstrated that the Smooth Insertion Spinal SIS System provided greater control for the clinician by reducing the buckling of G tra ...

ABSTRACT: The effectiveness of adaptive training systems has been repeatedly demonstrated. However, to foster widespread adoption, tools are needed to reduce the level of effort and cost associated with development and sustainment. To respond to this challenge, Sonalysts proposes to develop the Rapid Adaptive Coaching Environment (RACE). Using a guided authoring and maintenance approach, RACE ...
