The nature and requirements of military operations lead to high noise levels, exposing military and civilian personnel to the possibility of noise-induced hearing loss. Otoacoustic emission (OAE) probes can assess the health of the inner ear by testing the response of the cochlea to various types of stimuli. The measurement of emissions at high frequency has the potential to detect noise-induced d ...

In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

Sensatek Propulsion Technology, Inc. proposes to demonstrate the feasibility of a wireless, passive, nanoparticle-based sensor system. The sensor in its current form can be used to measure real time temperatures and pressures wirelessly without the need of an external energy source. It should be noted that the same sensing principle can be used for strain monitoring as well. It comprises of a micr ...

Firefly, in collaboration with Rochester Institute of Technology, proposes an STTR program for the development of a wide-bandgap GaP-based space solar cell capable of efficient operation at temperatures above 300oC. Efficiency enhancement will be achieved by the introduction of InGaP quantum wells within the active region of the wide-gap base material. The introduction of these nanoscale features ...

Optonicus proposes development of the WALAM-ABS (Wide-Area Laser Additive Manufacturing in Metals with Adaptive Beam Shaping) laser additive manufacturing (LAM) system. The WALAM-ABS metal additive manufacturing system will solve long-standing drawbacks imposed by current single-point selective laser melting LAM technology through the use of wide-area processing based on proprietary multi-beam fib ...

W-band millimeter waves have a number of important applications, including directed energy and, more recently, 5G FR2 network development. Reliable measurements of electric fields in the W-Band, while critical to the development of these applications, have proven challenging. This proposal addresses the development of an accurate, traceable, cost effective W-band RF field strength detector. The so ...

Nanoscale, material sensitive, imaging techniques are critical for progress in many disciplines as we learn to master science and technology at the smallest dimensions — on the nanometer to atomic-scale. However, progress in both science and technology is becoming increasingly limited by the constraints of current imaging techniques and metrologies. Fortunately, by combining coherent extreme UV ...

An integrated program of fundamental research, software development and technology transition to Navy target platforms for computationally efficient yet accurate prediction of turbulence interactions involving disparate length scales has been proposed and is underway. The fundamental research will be conducted at Purdue University and provide a critical modeling component for turbulence resolving ...

Suppression of noise from aircraft is a vital NASA goal, especially important for the vision of Urban Air Mobility. Small urban aircraft may utilize Distributed Electric Propulsion along with advanced structural and electric motor/storage technologies to achieve the necessary flight capability. However, these aircraft utilize propellers or fans to achieve the necessary thrust, with attendant commu ...
