Investment castings have well served both the military and commercial markets in such areas as waveguides and splitters for microwave applications, and for connectors, housings, heat sinks and mechanical parts for electronics, optical, instrumentation, and medical devices. Tomorrow's higher RF millimeter wave and communications electronics products, and more compact optical, instrumentation and m ...

Automobile three-way catalyst (TWC) are quite efficient at steady state operatingtemperature typically destroying 98% of incoming hydrocarbons (HCs) and carbonmonoxide (CO). However, up to 80% of emissions occur during the first fewminutes of Federal Test Procedure when the engine is running rich, the engine iscold and TWC has not reached light-off temperature. To significantly reduce HCsand CO ...

A novel method for preparing carbon electrode structures having applications in electrochemical double layer capacitors (EDLCs) is described. The method for preparing these structures employs carbon (graphite) nano fiber materials and results in an electrode having both high surface area and high electronic conductivity; two essential characteristics for EDLC electrodes. The fabrication process ...

The ability to rapidly detect, identify and monitor chemical agents remains a challenge of significant importance to the Armed Forces. Existing chemical sensing techniques have shortcomings that inhibit widespread implementation. To address this situation, Ryon Technologies is developing a portable instrument that is based on Rydberg Fingerprint Spectroscopy (RFS) in combination with mass spectro ...

Herein, we propose a novel approach to achieving a broadband, phased-array transmitter operating at frequencies from 100-300 GHz. Our approach is based on the concept of optically distributing a pair of locked optical tones to an array of antenna coupled photomixers. Lightweight optical fibers enable the distribution of these optical tones to any arbitrary antenna array geometry with antenna pla ...

Key to phased arrays that can scale to high frequencies, bandwidth and large apertures is an architecture that enables full digital beamforming and large-array performance with minimum electronics per element. Out of the three proven beamforming methods for phased arrays: analog, conventional digital and spread spectrum digital beamforming (SSDBF), just the latter scales well to large arrays at hi ...

In the current SBIR program, AlphaSense aimed at developing a novel, handheld, non-destructive sensor to evaluate the integrity of Naval Advanced Amorphous Coatings (NAAC) in real time. In phase I, we have proven the feasibility of using the cavity perturbation technique to detect different types of defects present in thermal-sprayed testing coupons. Specifically, we optimized the sensor probe des ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

To reduce size, weight, power and cost (SWaP-c), military platforms have been evolving towards more integrated platforms that utilize all available space. For radiating systems, this will require exploring innovative design methods, materials and manufacturing approaches to realize cost-effective, customizable and conformal antennas. An attractive solution to this challenge is offered by additive ...
