Emerging Trends in Medical Diagnostics and Therapy

New technologies are providing doctors and patients with more options for treatment and improved quality of life than ever before. Procedures once entailing long recovery times and scarring may now be done almost painlessly and without significant disfigurement. Drug therapies are being tailored to target specific aspects of a disease, and donor organs can be grown from sources from which rejection is eliminated. These approaches in medicine reflect a more focused ideology when confronted with injury and disease.

Clearer Images on Near Infrared Camera Made Possible with Filters

The James Webb Space Telescope (JWST) is scheduled for launch in 2013 and aims to unravel the history of earlier galaxies, linking the Big Bang to the Milky Way Galaxy. JWST’s Near InfraRed Camera (NIRCam) is a filter-based instrument covering the spectral range of 0.6 to 5.0 microns. The Principle Investigator for NIRCam is Dr. Marcia Reike of the University of Arizona, while the Advanced Technology Center (ATC) of Lockheed Martin is responsible for its manufacture, integration, and testing. Barr Associates recently was selected to design, manufacture, and test 30 filters for the JWST NIRCam. Barr previously provided spaceflight filters for Lockheed Martin ATC, including those for the Solar-B and shuttle glow experiments.

Software-Defined Radio Software Aids Development of Space Telecommunications

NASA’s John Glenn Research Center in Cleveland, OH, has chosen the Green Hills Platform for Software Defined Radio (SDR) — with Spectrum Signal’s flexComm™ SDR- 4000 communications platform — for the rapid design, development, and refinement of its next-generation Space Telecommunications System Architecture. The Green Hills SDR Platform includes the INTEGRITY® RTOS, a POSIX.1- conformant real-time operating system certified by the IEEE to the POSIX 1003.1 standard; a dual-mode IPv4 networking stack support; and waveform design and development tools.

New Coating Chemistries with Excellent Outdoor Durability

A multinational advanced materials company is seeking wet coating technologies that show excellent weathering and durability. The coatings need to be applied to glass substrates. The coating needs to have excellent outdoor durability in excess of 10 years, have a hardness of at least 2H, and be optically transparent (<1.0% haze might be acceptable). As well as the coatings being suitable for application in a solution, they also need to be able to be used as a binder or cross-linking component of coatings.

Flame-Resistant Fastening Between Two Fabrics

A flame-resistant fastening between two fabrics is sought, and must be simple to operate. The connection should resist frequent flexing, and must have a breaking strength of 120 kilogram-force. If folded cross-wise, it must withstand 40 kilogram- force, and may need to stand up to direct flame for 50 seconds or more. The resulting connection between the fabrics must be aesthetically pleasing. When subjected to flame, the connection cannot emit any toxic fumes.

Board Design Test Vehicle

The Board Design Test Vehicle is a method for objective evaluation and qualification of supplier capabilities for the fabrication of multilayer printed circuit boards. It is used to analyze and assess technical capability and reliability of products that are provided by a supplier, and provides a mechanism for supplier improvement with validation. The design incorporates features that allow for analysis of variables data to determine actual process capabilities statistically and accurately, with a minimal amount of effort. Data can be plotted with distributions to determine process capability, revealing whether the data is “filtered” or cherry-picked, and can help evaluate the repeatability and consistency of processes. The ability to validate design rules is provided and matches supplier capabilities to actual designs.
