Precision Detector Conductance Definition via Ballistic Thermal Transport

This innovation could be applied in the development of bolometric detector array sensors. Goddard Space Flight Center, Greenbelt, Maryland The characteristics of a thermal detector, such as sensitivity, response time, and saturation power (or energy resolution), are functions of the thermal conductance of the detector to its cryogenic environment. The thermal conductance is specified to achieve a tradeoff among the highest sensitivity, allowed response time, and the desired saturation energy or power budget for the particular application. It is essential to achieve the design thermal conductance (within an acceptable variance) after a thermal detector has been fabricated. Otherwise, the detector will fail to achieve its desired functionality. In addition, the formation of a multi-pixel imaging array becomes difficult and costly when the design thermal conductance is not achieved with high post-fabrication yield.

A Robust Supply Chain: The Important Role Your Contract Manufacturer Can Play

Your complex device demands a robust supply chain. In today’s unsure environment, you need to know that your supply chain is available, flexible, and affordable when you need it. Establishing a strong and effective partnership with a contract manufacturer can ensure that you have the purchasing power and agility needed when the unexpected happens or design changes are needed. “A Robust Supply Chain,” our White Paper, outlines three things to look for in a contract manufacturer and three things you can do to ensure a smooth production process and an improved bottom line.

Products of Tomorrow: January 2016

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Product of the Month: January 2016

Dewetron, Wakefield, RI, announced the TRIONet compact data acquisition system that accepts any two of the company’s multi-channel TRION series plug-in modules. The system connects to any Windows computer via USB 3.0 (or USB 2.0) or Ethernet. TRIONet mainframes can be interconnected using Ethernet. As a result, TRIONet mainframes can be placed up to 100 meters apart. Both star and daisy-chain topologies are supported, depending on the physical environment. A 9- to 36-VDC power input allows TRIONet to be operated from vehicle power. A small touchscreen color display shows the status, IP address, and health of the mainframe. Each mainframe can support up to 16 high-speed analog channels of many different types. There are various analog, digital, data bus, and timing modules available. Measuring 12.6 × 8 × 2.2", the system weighs 5 pounds with one TRION-2402-MULTI module. TRIONet consists of the mainframe, a TRION-2402-MULTI (universal input) 8-channel module, the company’s OXYGEN data acquisition software, and cables for both USB 3.0 and Ethernet. The system can be used with Windows 7 or 10 computers or tablets. For Free Info Visit http://info.hotims.com/61057-120

THz-TDS and THZ-FDS Imaging Systems

Terasense (San Jose, CA), in collaboration with Toptica Photonics (Victor, NY), has unveiled the first imaging cameras enhanced for time-domain and frequency-domain generation systems. The new cameras, developed for specific use in TDS and FDS systems, operate in the 50 GHz to 0.7 THz frequency range. Both products achieve 50 fps and pixel size dimension of up to 1.5 × 1.5 mm2. Image test results achieved are publicly available on the Terasense website for further analysis and inspection of realtime application. For Free Info Visit http://info.hotims.com/61057-205
