Aither's Custom Designed Force Sensor Used in MRI Environment (April 2010) Aither Engineering designed and constructed a custom FBG-based force sensor for use in Magnetic Resonance Imaging (MRI) systems. Research conducted utilizing the sensor has recently been published in the Journal of Neurophysiology and Human Brain Mapping, as listed below.

Aither Wins Phase I SBIR Award (February 2010) Aither Engineering, Inc. has been awarded a Phase I SBIR award for Real-Time Hull Shape Monitoring by the U.S. Navy (Topic Number N093-213). The topic abstract is provided below. The contract start date is expected to be in the beginning of April. Aither looks forward to this exciting new program to further expand our continuing research in fiber optic shape measurement technology. Aither’s proposed solution will examine the development of an innovative fiber optic hull shape sensing system based on a hybrid sensing scheme to allow for the extremely large number of measurement points required for the submarine structure. During Phase I, Aither will determine the required components for this system and attempt to determine a theoretical accuracy for the proposed system. Aither will also investigate the improvements that may be realized by incorporating the first methodology of monitoring the position of the forward and aft panels relative to the center panel on each side of the submarine into the hull shape monitoring system. Aither’s experience in fiber optic based shape sensing has been developed through multiple SBIR programs including towed sonar array shape estimation and aircraft wing shape measurement. Aither has developed patented, innovative technology through these programs and will leverage this experience to the fullest extent during the SBIR effort. Aither is well aware of the difficulties in not only developing a submarine hull shape monitoring system, but also with integrating the required optical fiber sensors with the submarine structure having completed ABS certification testing for a private customer on a 10 person submarine design. Aither Begins Phase I SBIR Award (December 2009) Aither Engineering, Inc. has been awarded a Phase I SBIR award for Optical Array Shape Estimation (ASE) by the U.S. Navy (Topic Number N092-137). The topic abstract is provided below. The contract start date was mid-December. Current methods used to determine the shape of towed sonar arrays are limited to basic models that use data from heading and depth sensors. These sensors are prone to measurement noise especially during maneuvers. The research team recognizes that neither a fiber optic measurement system nor a physics based model can achieve the desired accuracy for array shape independently. Through the combination of Aither’s fiber optic shape measurement system and Makai’s physics based modeling of towed systems, the research team proposes the development of the Fully Integrated Fiber Optic – Towed Array Shape Estimation System (FIFO-TASE). The system takes the innovative approach of incorporating both the fiber optic shape measurement data with input from the physics based model to realize the shape and orientation of the tow cable and towed array system. In this manner, the fiber optic sensor data is used more effectively, where the physics based modeling allows for the filtering of inaccurate data and improves the results when in “noisy” tow states. The FIFO-TASE system builds on the decade of work conducted by Aither personnel in the field of tow cable and array shape sensing providing an innovative means of enhancing and improving the resultant shape estimation.
