The Switch Reluctance Machine (SRM) is known to be subject to inherent excessive vibration and acoustic noise. A closed-loop control technique was developed in the Phase I to eliminate torque harmonics produced by a generic SRM. To provide vibratory feedback, a piezoelectric-based sensor is incorporated into an SRM drive system to sense the torque harmonics in real time. The control system has bee ...

To protect daytime cameras against broadband laser threats, innovative active optical materials and optical systems—designed to provide protection against pulsed lasers operating throughout the wavelength range of common daytime and low-light-level imaging cameras (400 nm through 1100 nm)—are being developed by Voxtel, Inc. The nonlinear optical (NLO) limiter developed in this work delivers un ...

Recent advances in commercially available Gallium Nitride (GaN) MOSFETS offer significant advantages compared to traditional Silicon devices for circuit protection and power distribution applications including the availability of devices in advanced packaging options, lower on-state resistances, and improved performance in harsh electromagnetic environments. To demonstrate these advantages of GaN ...

A compact, lightweight, direct-view variable-magnification fire-control riflescope with integral programmable aiming system will be developed, which includes: a 1550-nm eyesafe laser rangefinder (LRF), 9-axis inertial measurement unit with integrated environmental sensors and ballistic computer, and a real-time direct-view heads-up display (HUD) disturbed reticle. The proposed system will be demon ...

The lack of lubrication performance associated with JP-8 fuel in modern diesel engines equipped with High Pressure Common Rail (HPCR) fuel systems can lead to premature performance loss and catastrophic field failure. OEM¡¦s will need to first thoroughly understand these effects and then make provisions for JP-8 fuel compatibility as engines in the Army fleet are replaced with modern engines ...

The long-term readiness and operability of the U.S. Army tactical missile systems is critically dependent on the development and utilization of new methods to assure full life-cycle components’ health. Diffraction Enhanced X-ray Imaging (DEXI) technology has the potential to revolutionize x-ray imaging as it produces images with higher contrast than conventional radiography, while reducing ...

Odyssian Technology and its team of highly regarded experts propose to develop advanced distribution and control technology for hybrid intelligent microgrids. The novelty of their proposed concept is in the use of a wireless mesh network to control distr

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

A Weigh-in-Motion (WIM) system is being developed that will deploy in or on roadways of all types and accurately measure and report weights of crossing vehicles, including total vehicle weight and individual axle and wheel weights. The innovation in the system is that it senses horizontal (lateral and longitudinal) forces at each wheel and uses those measurements to correct for vehicle weight shi ...

In this Phase II research, Blacktoe Medical will design, manufacture and test a finger-worn ultrasound-imaging probe, optimized for Army vascular access requirements. The vascular finger probe will simplify use and reduce the time to learn complicated ultrasound guided procedures. By leveraging human hand-eye coordination and intuitive knowledge of finger position and orientation, the probe will a ...
