Secure trusted biometric validation of identity has never been more important. The increase in global terrorism, unfettered identity theft and new legislation requiring multi-factor authentication are a few of the driving factors. The biometrics industry has not actively responded to the changing market conditions being driven by the explosion in mobile computing. Millions of new mobile devices ar ...

Sensitive and expensive electronic equipment used in marine environments are generally subjected to harsh extremes. Component lifetimes are typically extended by physical isolation using bags, hard containers or with conformal impermeable coatings. However, over time, protective measures become compromised, the resulting exposure causing corrosion and short circuit-driven malfunctions. There is ...

Crossfield Technology LLC proposes the design and development of an Accelerated Processing Unit (APU) System on Chip (SoC) consisting of a hybrid CPU/GPU digital signal processor. The APU incorporates high-speed interfaces to external sensors and a NAND Flash Controller. The NAND Flash Controller implements XTS-AES-256 encryption commonly used for whole disk encryption, and can securely erase the ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

An existing low-cost FPGA-based processing platform will be demonstrated with fiber-coupling to single-photon detectors, to perform photon-arrival time stamping with

A stable, well characterized InGaAs materials growth and photodetector fabrication process will be used to fabricate matched photodiodes optimized for balanced homodyne detection. The 1-mm-diameter p-i-n photodetectors will be manufactured back-illuminated with a 5-micron absorber, allowing residual light to reflect off the front-side metal to make a double pass through the active layer. Ultra-hig ...

Voxtel has demonstrated efficient high-speed photon counting with thresholded linear-mode avalanche photodiode (APD) receivers using multi-gain-stage InGaAs/InAIAs APDs. In contrast to Geiger APDs, thresholded photon-counting linear APD receivers are thought not to suffer afterpulsing, and can support maximum count rates (MCR) up to 2 or 3 orders of magnitude faster than Geiger APDs. However, the ...

The objective of this proposal is to demonstrate the feasibility of developing flex hoses for hydraulic and other piping system interfaces that can withstand high pressure environments, hydrodynamic, and other forces unique to deep submergence system operating environments. This hose and connecter system coined FlexiHOSE© proposed by MEI-Charlton, Inc. (MEIC) will meet the need of operating under ...

Voxtel proposes to develop fiber-coupled near-infrared avalanche photodiode (APD) receivers with photon detection efficiency (PDE) and dark count rate (DCR) with more than two orders of magnitude faster maximum count rate (MCR) than Geiger-mode APDs, which are constrained by a fundamental tradeoff between DCR and MCR: if the APD is cooled to reduce DCR, then its dead time must increase to avoid af ...

Williams-Pyro is developing an AccuTag Miniature Surveillance and Tracking System (Accu-MiSTS). Accu-MiSTS employs cluster management techniques and ad-hoc networking to provide a readily scalable architecture with which to perform comprehensive surveillance. A cluster comprises one supernode and up to 65,536 nodes, all of which are within the communication range of at least one other node. The Ac ...
