Tunable Bandpass Filters

The ubiquitous techniques of fluorescence and Raman imaging and spectroscopy rely heavily on spectrally precise, high-quality and high-throughput optical filter technologies. As both fluorescence and Raman-based techniques move from traditional R&D-based environments into medical and clinical (diagnostic) settings, even higher demands are placed on system performance. Therefore, it is necessary to continue to improve system components and architectures to meet the demanding challenges often encountered in biological applications.

Software Improves Access to NASA Earth Models

Frontier Grid Platform for distributed computing Parabon Computation Reston, VA 703-689-9689 www.parabon.comAccess to complex climate modeling and simulation models from NASA’s Earth-observing satellites will be easier after development of a Web-based system from Parabon Computation. The company is working with NASA’s Goddard Space Flight Center (Greenbelt, MD) to help scientists access climate models. The models would be hosted as a Web service so users can access and run them in a Web browser, without the use of a local copy of the application.

Custom Assembly Helps Create Medical-Grade Saline in Space

BioConnect® bag and tubing assemblies Cole-Parmer Instrument Vernon Hills, IL 800-323-4340 www.coleparmer.comBioConnect custom bag and tubing assemblies supplied the materials and services to catalyze the production of a prototype for the Intravenous Fluid Generation (IV Gen) technology demonstration on the International Space Station. Funded through NASA’s Human Research Program, a team from NASA’s Glenn Research Center (Cleveland, OH) and ZIN Technologies (Cleveland) seeks to produce medical-grade saline solution in a zero-gravity environment. If successful, the process solves the challenge of packing IV solution that expires during the shuttle cycle, and alleviates mass and volume storage constraints.

Camera/Robot System Increases Quality and Reduces Costs for Vehicle Component Supplier

The Piston Group (Redford, MI and Liberty, MO) builds cooling modules for seven different vehicles. These cooling modules are built on five different assembly lines, with each line building more than 50 different variants in sequence to the customer’s demand. Many different inspections need to be performed on each module, including verifying the build variation, checking electrical connections, and all dimensional requirements.

Data Management Speeds Up Simulation of Crash Test Dummy Models

The idea for the automotive crash test dummy first came to life in the 1950s when U.S. Air Force flight surgeon Col. John Stapp realized that more of his fighter pilots were dying in car crashes than from accidents in their hi-tech jet aircraft. The Stapp Car Crash Conferences started that decade and continue today as a venue to share information on the latest research and advancements for improving vehicle crashworthiness and occupant safety.

Electro-Hydraulic Motion Controller for Earthquake Simulation

How do you test the behavior of different soil structures in an earthquake? Obviously, large earthquakes don’t happen often, and they certainly don’t happen on cue. The solution, of course, is to model earthquakes in a laboratory environment. And that’s exactly what is being done by the Center for Geotechnical Modeling at the University of California, Davis. Since it’s not economical to simulate the forces of an earthquake on fullsize soil structures such as one would find beneath a real bridge or large building, physical models of much smaller size are used. In Figure 1, for example, is a model of the San Francisco Bay Area Rapid Transit transbay tube that was recently tested in Davis1.

Managing a Network of Self-Encrypting Hard Drives

With high-profile data breaches making headlines regularly, organizations are carefully evaluating their options for protecting mobile data. For years, software full disk encryption, (FDE), has been the preferred means of addressing this threat. But widespread adoption has been hampered by the complexity and cost surrounding these software-based FDE deployments.
