The proposed multi-spectral IFF beacon will use 40 to 50 % effient high power laser diodes at 863, 1064, and 1550 nm wavelengths. Thermal emitters including diamond-like carbon thin films, photonic crystals, and quantum cascade lasers will be characterized and compared. Finally a model to predict the detection range of IFF beacons will be developed using proprietary emitter power and atmospheric ...

Diffraction LTD will develop a multi-spectral battery powered combat ID beacon. Key emitter technologies will include vacuum encapsulated photonic crystals in the MWIR and LWIR spectral bands. In Phase 1, a complete optical, electrical, and mechanical design of the beacon will be produced. A model taking into account emitter characteristics, atmospheric transmission, ambient lighting, and vario ...

Embedded usage tracking of helicopter rotating components, combined with active radio frequency identification (RFID) has the potential to reduce maintenance costs, reduce weight, maximize structural life, & enhance safety. Energy harvesting used with advanced, micro-power wireless sensing electronics, enables the realization of truly autonomous sensing and recording. The objective of this SBIR ...

Structural health monitoring (SHM) of large structures such as Navy ships requires an in depth knowledge of operational loads and how these loads may change over time. A network of low cost, wireless strain sensors can provide this information. During Phase I, we will demonstrate a highly synchronized, scalable network of energy harvesting wireless strain sensors. By converting ambient cyclic stra ...

Microbial contamination in kerosene based aviation fuels has been a problem for the USAF since the 1960’s. Antimicrobial effect of earlier used fuel system icing inhibitor (FSII) became an initial solution to this problem, but later, such fuel additives were banned due to their extreme toxicity towards humans. Newer FSIIs, being more eco-friendly, do not possess the antimicrobial properties of ...

Biodiesel is our next generation eco

This STTR seeks to develop a high-throughput, low-cost enabling technology for the manufacturing of electronic systems-on-film. It posits a novel concept of introducing percolation networks into semiconducting “inks” to increase by at least an order of magnitude the very low carrier mobilities (

A major limiting factor to organic cell efficiency is exciton diffusion and charge transport, which depend on charge carrier mobility in the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to ultimately improving >10% the efficiencies realized by typical organic solar cells, whether

A major limiting factor to organic photovoltaic (OPV) solar cell efficiency is exciton diffusion and charge transport, which depend in turn on carrier mobility and the E-fields created internally by the device materials and structure. Versatilis proposes a novel approach to enabling the better OPV cells from leading OPV makers to reach >10% efficiencies, whether

QuantaSpec, Inc., proposes to produce a highly efficient, compact, personnel-worn combat ID beacon visible to a large variety of overhead imaging pods. Multiple incidents of fratricide have highlighted the need for improved combat ID and Identify Friend or Foe (IFF) technology. Recent advances in emitter technology have enabled a new class of signaling device to become practical. QuantaSpec, Inc., ...
