Individual differences in vulnerability to sleep loss and fatigue from extended work hours and night work are a substantial problem in transportation policy making, work schedule development, fatigue risk management strategies, and prediction of performance impairment in real-world operations (Van Dongen et al. 2003; Mollicone et al. 2010). Our group was the first to document the considerable magn ...

In this Phase II SBIR project, Daniel H. Wagner Associates will develop a full-scale prototype Optimized Data Management Services (ODMS) for Tactical Environments and its primary service oriented components: the Enterprise Information Acquisition Service (EIAS) and the Information Flow Optimization Services (IFOS). Our main goal is to transition CMA service oriented components into current and eme ...

In Phase II, PiAC and CMU plan to develop and demonstrate an operational prototype of a VERTREP Object Proximity Warning System (OPWS) sensor and software. The prototype will be evaluated in a subscale demonstration using the actual sensor package and a surrogate mechanical system to simulate rotorcraft motion to land on a scaled ship deck undergoing pitch, roll, and heave motions. The operator wi ...

The U.S. Navy requires a new Environmental Wideband Acoustic Receiver and Source (EWARS) sensor to facilitate the gathering of environmental data from Navy ASW platforms. The newly developed EWARS sensor must be deployable in shallow and deep environments, and be capable of operating over a broad spectrum of frequencies. EWARS also requires calibration accuracy, digital uplink format/precision, an ...

A novel yet mature technique will be used to assimilate coherent-source multistatic ASW data obtained from drifting acoustic sources and receivers. We will demonstrate the technique's ability to correctly estimate the locations of drifting buoys from acoustic data only even when the buoys may drift significant distances during a mission.

Satellite RF components suffer from an additional design limitation that does not concern their terrestrial counterparts: multipaction, an electron avalanche effect that can reduce performance or permanently damage devices under certain conditions. To avoid the onset of this effect, the traditional options are increasing the component size (more specifically, gap widths) or reducing operating powe ...

In this program, we propose a radio frequency (RF) direction finding sensor for low probability of intercept (LPI) RF radar system. This sensor consists of a dielectric lenses focusing system and an innovative focus plane detector array (FPDA) developed by Spectrum Magnetics, LLC (SM). The focusing system project the RF signal onto its focus plane. A novel FPDA based on emerging spintronic and met ...

TRS proposes to develop an extremely low frequency sonar projector transducer miniaturized through specific designs that allow incorporation into an array on the large diameter underwater vehicles. Piezoelectric single crystal growth technology based on PMN-PT has advanced the acoustic transduction capabilities and has revolutionized various sonar platforms and TRS will utilize second- and third-g ...

In this SBIR program, AlphaSense, Inc. teamed with the Center for Non-destructive Evaluations at Iowa State University to develop a compact, low cost handheld sensor for non-destructive material case depth verification. In phase I, we have proven the feasibility of using an alternating current potential drop (ACPD) sensor for non-destructive measurements of case depth. Phase II will be focusing on ...

The noise from the turbulent, hot, supersonic jets at take-offs and landings dominates noise emanating from other powerplant components and has significant safety implications for launch personnel, as well as by the integrity of the structural components of the deck itself. With the impending induction of the JSF/F-35B into the US Navy in the near-future, concerns regarding noise emissions have ta ...
