State-of-the-art power electronics use discrete components such as power magnetic inductors and transformers operating at < 1MHz, which suffer from a large SWAP-C (size, weight, power consumption, and cost). It has been challenging to achieve simultaneously high inductance, compact size, and high quality factors at 1~300MHz for integrated power electronics. In the completed Phase II Army STTR Phas ...

Bacterial infections are particularly significant for military personnel in situations where there may be a long delay between the injury and treatment at a hospital or clinic. The development of an effective, portable light-based system which can operate in both military hospitals and far-forward situations is proposed. The proof-of-concept prototype developed in Phase I will be refined to be mor ...

Digital twins can be imagined as virtual, continuously-learning digital representations of physical assets. Such simulations have the potential to marry virtual and physical understanding of assets such that analog data from the physical product and its surrounding sustainment ecosystem is converted into digital data that is stored, analyzed, modeled, and learned by artificial neural networks (NNs ...

Challenge: Reliable & repeatable production of large format, high performance components that are difficult to source using conventional casting and forging methods. We will Deliver: A physics-based modeling framework that enables reliable and repeatable large-format component-level production of high strength (>200 ksi) Maraging Steel produced via Wire-Arc Additive Manufacturing (WAAM). Proposal: ...

In this program, Physical Sciences Inc. (PSI) will team with Professor Ali Adibi’s group at the Georgia Institute of Technology to develop a photonic integrated circuit (PIC) spectrometer that can simultaneously achieve high-resolution over wide-bandwidths using a scalable and foundry-ready approach. While a PIC-based spectrometer is a key component for on-chip Raman, fluorescence, and absorptio ...

The US Marine Corps needs a portable, hydroelectric generator to provide electrical energy to recharge batteries and power equipment. Electrical energy used in the field today is primarily generated using diesel generators. Having the option to use an energy source present in the environment, such as a river or stream, reduces the need to transport and store fuel. In order to meet the Marine Corps ...

We will integrate the Phase I demonstrated physics, modeling, simulations, nondestructive evaluation and Materials Identification Reflectivity Kernel (MIRK) discrimination technologies into a prototype for detecting Special Hull Treatment (SHT) delamination in water for significant cost savings and risk mitigation for the Navy. The resultant technology transition will focus on VIRGINIA and COLUMBI ...

This Phase II project is to design, build and test a bi-directional converter (BDC) utilizing wide-bandgap devices. The proposed BDC will be capable of converting 15kW power continuously between 600Vdc and 28Vdc voltage buses and fit into a ARINC 600 6-MCU enclosure. Utilizing wide bandgap technology devices including SiC and GaN MOSFETs enable the BDC to operate in a 71 Celsius ambient environmen ...

This research proposes a data-driven and multi-perspective solution to reduce injuries and fatalities due to bus collisions with other vehicles. It goes beyond reviewing historical bus crash reports by collecting field LiDAR data for better understanding a variety of factors that may contribute to bus collisions and injuries/fatalities. It also recognizes that collision avoidance technologies (whi ...
