Voxtel will develop a prototype ultra-high temporal resolution flash LADAR receiver suitable for unmanned ground vehicle (UGV) or unmanned air vehicle (UAV) applications, based upon its low-excess-noise, multi-stage avalanche photodiode (APD) technology. During the Phase I program, 5-stage InGaAs APDs where shown to have a multiplication noise characterized by k=0.02 at a gain of M=20 (20× lower ...

Intelligent tutoring systems (ITS) are complex adaptive learning systems that simulate one-on-one tutoring. Research shows they improve learning and reduce time to mastery. Unfortunately, they are also expensive and time-consuming to produce. Existing IT authoring tools eliminate low level programming but require that domain models, expert models and content be created manually. In Phase I of t ...

The web-based game, Numbershire II, will include modules to support students with or at-risk for disabilities in learning 2nd grade level mathematics, as defined by Common Core State Standards, including fluency with place value ideas, foundations of multiplication, and procedural fluency with multi-digit operations. In the narrative-based game, each student will build and maintain an idyllic Rena ...

The flexFORCE engineering team has completed assessment of the critical technical factors required for successful ASP deployment (weight, pointing accuracy, control response, actuation power required, failure modes and effects, scalability, and manufacturability). The team has evaluated the ASP operational environment and requirements, developed a preliminary system design, and executed both dyna ...

The previously conducted Phase I project had two goals: (1) to prototype and evaluate the feasibility of an intelligent computer-based task management application that would improve the ability of persons with cognitive disabilities to perform activities of daily living (ADL) and (2) to identify objectives for full development of a deployable system in a Phase II project. Intelligent multimedia ...

Bridger Photonics, Inc. and the University of Arizona have successfully demonstrated a Phase I dynamically programmable multi-band compressive imaging system. The team demonstrated three key technical concepts that prove the feasibility of this powerful technology: 1. Advanced algorithms were used to develop compressive measurement basis sets for imaging and target classification. The algorithms ...

Quantifying oceanic CO2 uptake and ocean acidification and understanding their impact on global climate and ocean ecology are key goals of NOAA’s climate change research programs. NOAA’s request for Development of a long-term Lagrangian pH and pCO2 drifter (SBIR Subtopic 8.3.1C) aims to address these goals by developing technology that measures both pCO2 and pH that can be widely deployed in t ...

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 ...

This NIST Phase II SBIR effort will two low noise single photon detectors using MgO doped LiNbO3 (LN) periodically poled waveguides and a 980nm (or similar appropriate wavelength) pump to up convert 1550nm photons to 600nm to allow for detection by photomultiplier tube (PMT). The key innovation is using low noise periodically poled waveguides with a long wavelength (1800nm) pump leading to higher ...

Because the data products generated by modern imaging ladar systems are inherently large in information content, there is currently a severe bottleneck in the communications of these products to end users, particularly when full-waveform recovery is desired. Bridger Photonics Inc. proposes to develop a dual-mode laser system capable of performing laser radar imaging as well as high speed free-spa ...
