Hy-Tek Manufacturing Co. Inc. (HMC) proposes a superior renovation solution for the DDG-51 class ships retractable mooring fixtures; namely bitt and chock assemblies. There are two major areas where technology advancements can be made that not only provide reliable bitts and chocks for use onboard U.S. Navy ships, but also have implications for other military and commercial applications. The first ...

WCDMA payloads on fast-moving platforms, such as on satellites in Molniya orbits or on UAVs, will likely be added to the battlefield to assure the warfighter of reliable, ubiquitous communications. The algorithms for handoffs, timing, and Doppler correction suitable for near-Geosynchronous platforms will not be suitable for these fast movers. Power control algorithms may or may not be suitable. Th ...

WCDMA repeater payloads being developed for deployment on unmanned aerial vehicles will provide enhanced beyond line of sight coverage with guaranteed Quality of Service for the warfighter. To become a reality, these payloads will require deployable multiband base stations to serve as the ground infrastructure. The base station will be designed in this project, thereby enabling this network archit ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...

We propose an innovative Pedestrian Automotive System for Enforcement and Safety (PASES) that combines commercial-off-the-shelf video or camera components and state-of-the-art microwave(radar) systems with sophisticated software that will not only provide more effective enforcement through effective evidentiary information, but will also enable predictive actions based on vehicle and pedestrian be ...

Spectroscopic ellipsometry is recognized as the gold standard in noncontact characterization of the refractive index and thickness of a thin optical film or film stack on a substrate. However, it suffers from a number of shortcomings, perhaps the most important of which is the time required to perform a single measurement. Moreover, manufacturers are interested in comprehensive evaluation of thin ...

We will develop and evaluate algorithms for a system, Veriflow, which can automatically reason about security and correctness of computer networks in real time. Veriflow operates by scanning a network, constructing a formal model of the network's behavior, and using custom formal logic algorithms to automatically derive whether the network contains inconsistencies, errors, or violations of sp ...

Radar signatures of small boats and ships are inherently complex due to their myriad topside features: railings, antennas, masts, ladders, armaments, pilot stations, outboard engines, storage bins, etc. In boats, the use of fiberglass and other radar-penetrable materials for hulls and decks further complicates the radar signature by exposing interior geometry. Radar detection, identification, and ...

Modern military systems contain numerous avionics and electronic systems that must perform to very high standards in hostile environments in the presence of numerous potential sources of electromagnetic interference (EMI). On airborne platforms for example, there could be dozens of RF systems radiating and receiving mission critical signals simultaneously over a very wide range of frequencies. Und ...

The Navy needs an optical repeater based upon the NGCON (MIL-PRF-64266) because the optical power loss budget on military aircraft is demanding. A bi-directional optical amplifying repeater would address the optical loss issue of connecting a fiber optic link in the aircraft network. Challenges include meeting the requirements for shock and vibration, operating temperature range, and optical port ...
