A report discusses the second generation of the JPL Electronic Nose (ENose), an array of 32 semi-specific chemical sensors used as an event monitor to identify and quantify contaminants released into breathing air by leaks or spills. It is designed to monitor the environment for changes in air quality, and is...

A modification of the basic design of cobra probes provides for relatively easy replacement of broken thermocouples. [Cobra probes are standard tube-type pressure probes that may also contain thermocouples and that are routinely used in wind tunnels and aeronautical hardware. They are so named...

A high-birefringence optical material suitable for implementation in optical systems is sought. This material has several qualities of interest beyond high birefringence: high hardness, making it amenable to standard polishing and manufacturing processes; low CTE (coefficient of thermal expansion); low CTRI...

A technology is sought that indicates that a product packed into a rigid metal container has not been tampered with and/or degraded over time. The solution must incorporate a method of communicating this information to the packager, retailer, or consumer. After packaging, and depending on the product, the...

Bioactive Hybrid Materials for Photonic Microsystems It allows samples to be analyzed on site within a few minutes by integrating biotechnology, information technology, electronics, physics, and chemistry to realize small and cost-effective bio-photonic microsystems.

The new single crystals offered here possess exceptional properties and are poised to revolutionize piezoelectric materials applications. In addition to strain levels exceeding 1% (usable strain: 0.5% at 35 kV/cm), these crystals exhibit five times the strain energy density of conventional...

Lightweight carbon-carbon (C/C) composites produced by pressure-assisted co- polymerization of carbon fibers, hydrocarbons and fullerenes have excellent mechanical properties and high thermal stability that make them ideal for thermal protection applications.

Qbit’s proprietary line of data compression software offers 100% mathematically lossless data reconstruction that ensures that every bit is reconstructed. It allows for an increase in digital throughput, workflow speed, and acts as an enabling technology for applications that...

This patented surface contamination detection system enables accurate, automated, in-line inspection of metallic and composite panels prior to bonding, coating, painting, or welding operations. This technology is currently used for realtime, in-process panel inspection at a...

A monolithic silicon nitride ceramic is densified at temperatures lower than 2000 degrees Celsius, and heat-treated at temperatures greater than 2000 degrees Celsius. This monolithic silicon nitride has a highly acicular microstructure and average apparent aspect ratio greater than 1.8. It also offers excellent damage tolerance...

Researchers at MIT have demonstrated how ordinary spark-ignition car engines can, under certain driving conditions, move into a spark-free operating mode that is more fuel-efficient and cleaner. The new capability could be available in production models within a few years, improving fuel economy by several miles per gallon. Over time,...

A manufacturer is looking for a detector array for the infrared region to detect two-dimensional radiation patterns. The sensor should have 1000 x 1000 pixels (or at least 512 x 512 pixels), which are individually addressable. The detector array is comparable to a high-speed CCD chip, but must have high sensitivity in the...

The qualities that we expect in our cell phones and PDAs -- anytime connection and low-cost, widely available devices -- soon may become common in health-care devices at home and in doctors' offices. The University of Florida (UF) and IBM have developed a new technology that creates a roadmap for widespread commercial...
