As the human population grows, it is critical to decrease consumption of materials from the planet and its ecosphere. The world adds 70 million people annually. The UN expects the population to grow to over 9 billion 2050. Climate change, soil degradation, unstable water supply all reduce the ability of traditional farming to satisfy food needs. Population increase and scarcity of resources and fo ...

Exploitation of new chip-scale optical frequency comb sources demands improvements in MWIR/LWIR detector performance, including: High speed (5 GHz); high sensitivity (NEP < 1pW/Hz1/2); broad spectral response (Octave); and thermo-electric cooler (TEC) operating temperature. No existing detector meets these demanding performance parameters. Phase I successfully designed and demonstrated an octave s ...

Exploitation of new chip-scale optical frequency comb sources demands improvements in the performance of MWIR/LWIR detectors. These detectors must meet the following specifications: High speed ( < 5 GHz), high-sensitivity (NEP < 1pW/Hz^1/2), broad spectral response (Octave), all at TEC operating temperatures. At present, no single detector exists that meet these demanding performance parameters. I ...

In this Phase II program, improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies, which Amethyst has successfully demonstrated in the Phase I program: unipolar barrier (e.g., nBn) detector structures, and defect passivation via hydrogenation. This two-pronged approach addresses the main performance limitation of extend ...

The DOD has a need to leverage state of the art technologies remotely detect, collect, and evaluate physiological signals of interest. Applications and concepts-of-operations (CONOPs) that would benefit from this capability include, but are not limited to: building-clearing, warfighter health monitoring or battle damage assessment and triage, situational awareness and assessment. The main goal o ...

Improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies with which Amethyst has demonstrated success: nBn detector structures and defect passivation via hydrogenation. Similar to conventional extended wavelength photodiodes, the improved sensors will based on mismatched InGaAs grown on graded buffer layers on InP substr ...

The objective of this research is to enable pre-process milling parameter selection for"first part correct"production. In the proposed solution the Receptance Coupling Substructure Analysis (RCSA) approach will be used to couple the measured spindle-machine dynamics to models of the tool and holder and predict the assembly"s dynamic response. Given this information, frequency/time-domain algorithm ...

As an alternative to near-obsolete double-base or triple-base propellants, Digital Solid State Propulsion (DSSP) is developing Electric Solid Propellants (ESP) as a safe, green, higher performance highly manufacturable alternative for high velocity electro-thermal-chemical (ETC) gun rounds. These electric energetic materials are inherently safe, with ignition only possible via the sustained suppl ...

As an alternative to double-base propellants we propose electric solid propellants (ESP) as a safe, green, higher performance alternative to double-base propellants for high velocity electro thermal chemical (ETC) canons. These new energetic materials are inherently safe, with ignition only possible via the sustained supply of electrical power and not by spark, flame or even bullet impact. A maj ...

CPU technology has progressed to a point of diminishing marginal returns in its current direction. The great success of the highly pipelined sequential processor has now become a hindrance to the efficient scalability for the evolutionary escape route of cookie-cutter chip multi-processor (CMP) designs. RISC instruction sets exist because they are easy to decode and pipeline, but they have relativ ...
