Many aquatic creatures transduce magnetic and electric fields for navigation cues and feedback control. Such sensing capabilities would greatly advance AUV technology. We will continue the co-design of sensing and motion capabilities along with empowering algorithms for underwater perception and navigation. We have made significant advancements in active electrosense and inductive-magnetosense in ...

Modern aircraft include numerous RF systems and associated antennas of diverse types. The designed performance of antennas is typically degraded by their installation on the airframe. Also, the presence of many RF systems in a small region creates enormous opportunity for undesired interference via antenna-to-antenna coupling. These conditions present serious challenges for engineers tasked with i ...

Delcross Technologies proposes to develop an automated measurement system (AMS) that will characterize the spectral profile of transmitters and receivers while minimizing manual labor. Modern RF systems can utilize thousands of channels, which makes a manual measurement system impractical for characterizing such devices. The purpose of the AMS is to create a practical process for RF system charact ...

Physics-based modeling and simulation tools for predicting electromagnetic interference (EMI) and vulnerability (EMV) between RF systems are playing an increasingly important role in system level performance predictions. In order to accurately capture all of the complexity associated with RF systems on a modern military platform, very sophisticated multi-physics simulators using models of multiple ...

Current infrared countermeasure (IRCM) systems are limited by the size and weight of their jamming transmitter. For current, as well as future, countermeasure systems, mid-infrared diode lasers need to be produced which can satisfy the power needs for IRCM while minimizing the system size and weight. While laboratory demonstrations have shown the technological feasibility using quantum cascade las ...

Cathodic protection methods, employing a sacrificial anode, are used to prevent corrosion of iron-based structural components in marine environments. However, as a consequence of galvanic coupling, hydrogen charging of high-strength steels occurs leading to hydrogen embrittlement and stress-corrosion cracking (SCC). Under this proposed SBIR program, QuesTek Innovations LLC, a leader in the field o ...

The objective of our Phase II work is to develop and demonstrate the Magnetic Underwater Mine (MAGNUM) confirmation sensor and associated integrated UUV sensor module. In the Phase I project, Sky Research and Geometrics explored the use of Micro-Fabricated Atomic Magnetometers (MFAM) technology to meet the Navy’s needs. The prospective MFAM sensor, data acquisition, and processing module have be ...

Current methods of growing carbon nanotubes (CNTs) of specific chirality yield mixtures of single-walled CNTs (SWNTs) with different structures and electronic properties, and methods to separate nanotubes by their electronic properties remain expensive and small-scale. Accordingly, synthesis today entails high capital and operating costs. A process is proposed that sidesteps the most difficult pro ...

Nighttime bioluminescence poses a large naval tactical problem. Therefore a navigation aid is required for underwater vehicles (manned or un-manned) that will sense the platform-induced (e.g. an Unmanned Underwater Vehicle, SEAL Delivery Vehicle, or diver) bioluminescence, water optical properties, and ambient light, and use the measured parameters as input to solve a simple radiative transfer alg ...

1We are proposing a computerized tomographic (CT) dimensional measurement system that will remedy two of the major problems experienced by current methods: the distortions caused by CT artifacts, and the blurring caused by the system point - spread function (PSF). The distortions resulting from data nonlinearity will be corrected by a calibration process acting upon the x-ray data. The blurring er ...
