International Electronic Machines (IEM) Corp. will develop the Intelligent Dimension Evaluation and Alerting System, or IDEAS.  In Phase I, IEM will examine two different approaches for achieving the goal of accurate, reliable dimensioning and classification of moving vehicles at highway speeds.  IDEAS will leverage prior work by IEM for the Federal Railroad Administration (FRA), New York State

Current inspection, maintenance and lifetime estimation practices for composite cylinders have been adopted from earlier NASA research. WavesinSolids LLC are proposing a technological based on an acoustic emission (AE) technique for the in-service testing of composite cylinders. The approach will establish the correlation between AE activity and intensity metrics and the stress intensity factor, a ...

During Phase I, IEM developed a proof of concept for a Smart Grade Crossing Monitor (SGCM) using multispectral imaging technology for enhanced monitoring of highway rail grade crossings to improve safety by providing warnings of significant objects present in the crossing. The Phase I work conclusively demonstrated that multispectral imaging is clearly superior to visible or infrared spectrum imag ...

As stated in the solicitation, the pavement infrastructure in the US covers a large surface area and requires intensive energy and natural resources. In addition, the surface of the pavement is typically impermeable, causing negative consequences. Vehicles that travel over these pavements are also resource intensive. Solar Roadways Incorporated envisions replacing current asphalt surfaces with m ...

We propose a metamaterial-enhanced microbolometer with strong absorption over a narrow band that is dynamically tunable over the 8-10 micron band. A single-layer photonic metamaterial consisting of a thin metal film perforated with a 2-D array of dielectric apertures will be deposited on an amorphous-Silicon layer acting as an absorber and bolometer. The metamaterial, in conjunction with planar di ...

Hyperspectral imaging systems acquire the spatial and spectral information of the image scene simultaneously, and thus find important applications in remote sensing, military surveillance, and target identification. Most contemporary hyperspectral imaging systems operate at UV/VIS/NIR (ultra violet/visible/near infrared) spectrums. However, in many cases, especially in military applications, (hype ...

This topic addresses the need for compact efficient solid-state deep ultraviolet (UV) lasers operating in the wavelength range of 220-250 nm, for use in Raman systems for chemical and biological detection. The laser to be developed would also be very useful in the detection of explosives. We propose to develop an efficient 946 Q-switched nm laser system that is efficiently quadrupled to 236.5 nm. ...

There is a market need for high intensity sound sources that can operate for long durations over wide temperature ranges and in environments with dust and humidity exposure. Piezoelectric sound sources offer many advantages over compression drivers in these applications. They can be small and lightweight, have low power consumption, operate in narrow frequency bands, and can achieve a high sound p ...

KCF Technologies proposes to develop a robust and efficient sound generator for separation/isolation of aerosols. The critical limitations in the performance of conventional piezoelectric sound generators include degradation in performance over long periods of operation, poor electro-acoustic efficiencies at high amplitude drive levels, and large tolerances in their acoustic performance. These pro ...

Currently, the accepted standard experimental model for measuring protective efficacy against botulism is the Mouse Lethality Neutralization (MLN) assay. Botulism poisoning is a life threatening condition that is not only a public health concern, but could also be a potential biological weapon. With seven serotypes of botulinum neurotoxins, there is need for an alternative to the MLN assay due t ...
