Available features to detect personas vary depending on the type of intelligence one is observing, and only facets of a persona are observable in each medium. New and enabling technology needs to be developed to search, capture, compare and identify disparate behaviors that may represent personas of interest. In response to this challenge, 21st Century Technologies proposed the Phase 1 Automated C ...

Maintaining accurate position location information (PLI) during operational missions is a critical requirement for the dismounted soldier. This requirement is unmet in heavily forested and jungle environments where GPS reception is unavailable due to dense canopy cover. In such environments, soldiers must determine their location by using visual landmarks, or by seeking open clearings where Global ...

For the U.S. Navy, Creare is developing a Compact Swaging Machine (CSM) to attach arresting gear Purchase Cable terminals on ship. Our CSM utilizes three innovative features to dramatically reduce the size and weight of the swaging machine to make it usable in a shipboard environment: (1) a high pressure hydraulic system which minimizes the actuator size, (2) an efficient swaging schedule which re ...

Typical piping joint designs in the fuel systems of Navy ships are susceptible to weakening due to poor inherent weld quality and localized corrosion. The current composite patches and other processes that represent the state-of-the-art for reinforcement weakened areas are expensive; difficult and potentially hazardous to install; and not durable. Our novel solution to reinforce weld joints and ot ...

This is a proposal to design a compact visual odometry sensor that can be mounted on unmanned ground vehicles. Visual odometry (VO) is a technique that estimates the ego-motion from images perceived by moving cameras. A self-contained visual odometry sensor would provide several significant benefits to unmanned ground vehicles, including: 1) providing position information to platforms that do not ...

High performance metals, ceramics, and hard coatings are used in military applications to enhance the performance of key systems needed by the warfighter. One of the most prevalent operations to remove material, achieve the desired surface finish, or enhance part quality is bulk and finish grinding. For typical cutting speeds, conventional synthetic or oil-based coolants are sufficient to remove ...

Chronically implanted neural electrodes are used to treat various neurological and neuropsychological disorders and for brain-machine interfaces used to control advanced prosthetics. Powering these systems with batteries is risky due to loss of power and energy over time, necessitating additional surgery, creating a lapse in treatment and additional risks from potential exposure to toxic material. ...

THIS PROJECT FOCUSES ON THE TWO MOST IMPORTANT ISSUES OF ALL OF COMPUTATIONAL FLUID DYNAMICS: 1) HOW GOOD ARE THE NUMERICAL ANSWERS OBTAINED IN A COMPUTATION? AND 2) HOW CAN THE BEST POSSIBLE ANSWERS BE OBTAINED FOR A FIXED AND LIMITED COMPUTATIONAL EFFORT, BUDGET, OR COMPUTING CAPABILITY? IN GENERAL TERMS THE ANSWERS TO THESE QUESTIONS ARE 1) TO DETERMINE RELIABLE A-POSTERIORI ESTIMATES OF ERROR ...

Erigo proposes to design, build, and test a titanium purchase cable that has several key advantages compared to steel arresting cables currently used by the Navy. Titanium has a much higher strength-to-weight ratio and greater intrinsic flexibility than steel, reducing the load imposed on other portions of the arresting gear system. Leveraging advancements in titanium alloy development, coatings, ...

The energy needs of naval aircraft are increasing significantly as the Navy modernizes its fleet. Current lithium (Li)-ion cells are insufficient for meeting these requirements. Li-air chemistry has the potential to meet the Navy’s energy demands. However, the state-of-the-art non-aqueous Li-air cells suffer from sluggish charging kinetics, clogging of mass transfer pathways and high resistance ...
