The feasibility of developing a photonics-based, real-time, high-power-radio-frequency (HPRF)/high-power-microwave (HPM) detection-and-analysis system is to be investigated. Design and development of foundational elements will take place to demonstrate how self-contained, shielded, photonic and source-power subsystems, interconnected to a network of non-polarimetric sensors via optical fiber, will ...

We propose to create TEAMMATE, a system that can give individual instructor trainees Tailored, Extensible, Automated Mastery Measurement for Actionable Teaching Evaluation. TEAMMATE will combine low-cost, COTS sensors like a camera and microphone with intelligent software to assess multiple key aspects of verbal and nonverbal communication. Like a peer observer in civilian teacher training, TEAMMA ...

For many programs, it would be desirable to fail fast in the face of attack in order to preserve confidentiality and integrity. We propose a tool to statically rewrite binaries to increase their fragility, adding this fail-fast property. We will operate on binaries to maximize the number of programs we can protect. Binary rewriting can be applied to any program without cooperation from the compile ...

Oceanit proposes to create technologies to improve diver communications at working depths compensating for different gas densities and minimizing communication feedback. The goal is to investigate applications of digital signal processing and actuators (speakers and microphones) and apply these findings in developing a Helmeted Diver communication system(s). This development is to address diver he ...

Low cost and high capacity make lithium sulfur batteries (LSB) the next generation of lithium ion batteries. Practical application of LSBs remains limited by low utilization of sulfur and fast capacity fading of sulfur cathodes. The root causes are poor electronic conductivity of the cathode combined with high solubility of intermediate polysulfide products formed during cycling. To overcome these ...

Oceanit proposes to design a software application that can be used with an infrared (IR) sensor to identify a potential target threat by analyzing its infrared signature.

The primary goal of this Phase I research effort is to develop manufacturing methods to grind and polish glass substrates into non-rotationally symmetric freeform conformal sensor windows with dimensions up to 12x12 inches with a sag height of approximately 4 inches and an RMS optical precision of 0.5 micron or better.

Access to experienced technicians is not always available to a maintainer at sea. Correcting naval electronic systems issues as they occur can leverage accumulated knowledge that resides in databases, detailed test plans, repair procedures, and other documents if available to ship-based maintainers. This effort is to develop an Interactive Instructor chatbot technology that is an interface between ...

Research the use of laser powder bed fusion to provide a lower cost method to manufacture complex geometries in C103 and other refractory metals.

The United States Navy has a special need to provide potable water for deployed personnel worldwide. The logistical and economic cost of provide potable water is considerable. There is a critical need to develop lightweight, energy efficient, squad sized water treatment systems that can create potable water from any water source. Although many technologies which can purify water; current technolog ...
