During Phase I, HMI concepts were developed to facilitate work load sharing, collaboration, and interoperability of tools and displays. Attention was given to simplicity and efficiency to reduce the number of menus and button clicks, eliminate windows, and simplify controls to be more intuitive.In Phase II the conceptual displays will be developed into a fully functioning prototype and integrated ...

This project involves the development of hull mounted acoustic motion (accelerometer) sensor with increased sensitivity (+6dB), greater stability, and low cost for hull mounted sonar arrays. Investigations and developments of sensors without and with preamplifiers is considered.

The objective of the proposal is to reduce the cost of fabrication of sapphire optical hyper-hemispheres for submarine masts. Due to the nature of sapphire, deriving complex geometries from grown boules using current conventional fabrication techniques is one of the major contributors to cost. Removing excess material requires long diamond grinding cycles. New advances in ultrasonics have been inc ...

A system to covertly communicate in underwater acoustic shallow water environment for mine countermeasure is described. Techniques for LPD and directional communication are suggested.

The primary barrier to widespread adoption of solid-state lighting is its high initial cost relative to other options approximately two times more expensive than equivalent compact fluorescent lamps, and five times more expensive than equivalent downlight fixtures. The performance and cost of solid-state lighting driver circuitry, which comprises 15-20% of the cost of a commercial lamp, operates ...

Geometrically constrained underwater environments abrogate the simplifying acoustic modeling assumption that energy can be modeled in a two-dimensional vertical plane. In these environments, current tools to perform navigation and passive and/or active sonar mission planning are inadequate. Furthermore, channel complexity makes it difficult to model acoustic communications. HRC proposes to upgrade ...

This proposal considers technologies and methods to realize low probability of detection (LPD) acoustic modem systems using low SNR techniques, camouflage techniques, and directionality to enhance covertness. Phase I baseline designs will be recommended based on past and new work of the contractor

The focus of Phase II shall be to demonstrate the feasibility of alternative seaming technologies for military use. Building on the work in Phase I and the Phase I Option, the NWU Parka Type I shall be the demonstration model for comparison purposes of technology advances. This high cost garment utilizes both traditional stitching and complex seam sealing techniques, and is an excellent example fo ...

The opportunity of interest is the introduction and application of a bistatic tool set for both surface and submarine Mid-Frequency (MF) active sonar systems to enhance anti-submarine warfare (ASW) capability in strike group or coordinated surface and submarine ASW operations. The ability to localize threat submarine forces in a battlefield scenario by judicious application of bistatic capability ...

This project will develop a novel, multi-wavelength integrating nephelometer, for use on small aerial platforms; such as UAS, tethered balloons, kites and other space-constrained applications. The main goal is to reduce the size of a typical research grade integrating nephelometer, maintaining its detection limit in the miniaturized device through technology innovation. The proposed nephelometer w ...
