We propose an all-fiber approach to heat removal from devices such as IR and LWIR detectors and sensors. In our approach, the cooling fibersegment, the pump fiber laser, and the optical fiber used for photon waste removal are all integrated into a single fiber configuration. NPPhotonics' high efficiency fiber lasers are used to pump high purity doped glass fibers, which provide the cooling action ...

Technological Enhancements to Improve and Expand Casual Carpooling in New Corridors 12/05/2016 The overall goal of Phase II of this SBIR project is to demonstrate a working prototype of one or more tools and/or approaches that catalyze casual carpooling in a corridor where it does not exist or to improve casual carpooling in a corridor where it is present but underperforming. Phase II will provi ...

We propose to develop low cost extended range Short Wave Infrared (SWIR) Focal Plane Arrays (FPAs) using Colloidal Quantum Dots (CQDs) technology. We have successfully produced a SWIR FPA camera with a resolution of 640 x 512 pixels and a sensitivity from 0.4 mm to 1.7 mm at room temperature. Our first initiative will be to extend the operational wavelength range to 2.5 mm, and then 3.0 mm. We hav ...

Physical Sciences Inc. (PSI) proposes to develop an open-path spatial ringdown spectrometer (OP-SRS) for the detection and quantification of chemical warfare agents (CWAs) and toxic industrial chemicals (TICs). This approach enables sensitive and selective detection of the chemicals of interest over a broad dynamic range down to the 10 minute negligible military exposure guideline (MEG) level. Thi ...

Highway-rail grade crossings, at which there is an abrupt change in the level of the road surface as it crosses the tracks, present a severe hang-up risk to vehicles with low ground clearance. In Phase I and II, ATR developed a conceptual design for a Low Ground Clearance Vehicle Detection System (LGCVDS) to actively prevent such accidents. The LGCVDS is able to use a priori crossing profile data ...

Luna Innovations is addressing the need to develop novel fluid repellent textile treatments for military uniforms that will activelydecontaminate chemical and biological warfare agents (CBWA). There have been recent significant advances in textile treatments that havedemonstrated water, oil and chemical agent resistance that are superior to Quarpel repellent treatments currently used on protective ...

Air parameters such as specific surface (SS) and spacing factor (SF) are essential in evaluating Freeze-Thaw (F-T) durability in fresh concrete. Currently there is no method or device that can accurately meet such requirements. We propose to develop an acoustic air void measurement system that can be used in the field to measure in near real time air void distributions in fresh concrete. The propo ...

The service life of the wood ties has been diminishing with increased axle loads with higher rail car speeds and frequencies. The depletion of wood and creosote induced contamination are of great environmental concerns. It is of a substantial interest to develop an effective recycling/remanufacturing methodology for creosote-treated wood ties. A composite wood tie design is proposed here, with use ...

The identification of high-value and high-impact secondary applications for retired lithium-ion batteries is critical as the number of electric vehicles on the road continues to increase. During the Phase I DOT SBIR program NanoSonic will evaluate second-use application concepts for retired vehicular lithium-ion batteries in economically valuable, second-use sectors of transportation. We are partn ...

This SBIR proposal presents a robust and cost-effective pedestrian and cyclist detection and collision warning system for transit buses. It uses inexpensive but robust sensors and incorporates state-of-the-art object detection techniques to enable effective pedestrian and cyclist detection near transit buses in different environmental conditions. The proposed collision warning system exploits meas ...
