High performance fiberoptic switch is an enable technology for new generation optical telecommunication and fully secured quantum communication/cryptography applications. Current fiberoptic switches do not simultaneously meet the requirements of high speed, low loss, high extinction ratio, and high reliability. Based on the successful development/production of a variety of industrial leading solid ...

Recent terrorist actions, particularly the delivery of anthrax via the US Postal Service, have triggered an urgent need for an early warning system for disease outbreaks due to bioterrorism. In response, we have developed, under a Phase I SBIR effort, a Bayesian Belief Network (BN) approach for Automated Link Analysis for Data-mining of Distributed INformation (ALADDIN) for early outbreak detectio ...

At present the need for a large area, 100 square centimeters or greater, soft x-ray fluorescence detector with high detection efficiency is required for material science and x-ray absorption spectroscopy. The current methods of detection used in x-ray absorption spectroscopy are subject to poor collection efficiency, large background and vacuum risk. It is the task of this grant to develop a multi ...

We propose to develop the next generation cryogen-free Adiabatic Demagnetization Refrigerator (ADR) system. It is a two stage ADR system that employs a self-shielded conductively cooled superconducting magnet and non-filamentary support for the paramagnetic pills. This is an improved version from Janis current cryogen-free ADR system product line, and the new system will be more user-friendly and ...

In this Phase I SBIR, Nomadics will build on our past experience with micro-structure resonators and quartz-based sensors to develop a pressure sensor suitable for high pressure applications such as oil and gas industry applications. In the Phase I work, the outstanding measurement resolution of our sensing technology will be demonstrated and the feasibility of this technology for pressure sensing ...

Summit Safety will develop an ultrasonic, non-contact sensor and system capable of detecting the acoustic sounds and fire-induced vibrations of structures that are precursors of structural collapse. The system will provide advanced warning to the Incident Commander of potential or imminent structural collapse. COMMERCIAL APPLICATIONS: The total US market for this product includes the over 1 mill ...

A lightweight, low-cost system for each firefighter to detect the location and direction of other nearby firefighters will be provided. A heads-up display will allow hands-free operation. The system will be integrated with the Personnel Ultrasonic Locating and Safety Equipment, or PULSE, developed by Summit Safety. This system uses ultrasound -- sound waves above the normal hearing range -- to ena ...

The Direct Digital Phase Noise Measurement Phase 1 SBIR demonstrated the feasibility of the technology to make the measurements required by the commercial marketplace. This new approach to phase noise measurements uses fast digital-to-analog converters to digitize the input RF signal and performs all down-conversion and phase detection functions by digital signal processing. It has several signifi ...

The development of tomographic SAR imaging is arguably the next big step in the evolution of imaging radar systems. The value of a successful volumetric imaging system to the US Government is clear. While successful demonstrations of volumetric imaging capabilities from various radar platforms have been made recently, there remains significant issues regarding data acquisition, signal processing ...

Leveraging Agiltron’s industrial leading developments for optical measurement of motion in MEMS devices, we propose to use electro-optical sensors for measuring the displacement and gap in the NIST micro-rheometer. No electrical connections are required to the moving parts. All electronics and optics are removed from the chip so that it is inexpensive and disposable. A fixed, simple micro-fluidi ...
