Connectors

LEMO (Rohnert Park, CA) has added a new connector size to its M Series. The new MM connectors are the most compact in the lightweight M Series product line. The MM connectors are available with 3 or 4 contacts and are some of the smallest IP68 connectors that LEMO offers. With this very small connector, LEMO completes the M series range of connectors for the automotive / racing / aerospace market by offering connectors suitable for cable diameters 2 to 27mm and contact configurations from 2 to 114 contacts. MM Plugs and cable mount sockets come with LEMO's signature ratchet-coupling shells and offer excellent weight and space savings with superior environmental protection. http://www.lemo.com/en

Raspberry Pi Model B Enclosure

Hammond Manufacturing (Cheektowaga, NY) has developed a new molded enclosure specifically designed to house the Raspberry Pi Model B credit card sized computer. The 1593HAM is available in translucent blue, grey and black. The Raspberry Pi board clips into the base and, in turn, the top half of the enclosure then clips into the base. A catch secures the assembly and allows the case to be easily opened if required. All I/O capability is directly accessible without having to modify the enclosure. The camera module can be fitted through a slot in the top, or it can be screwed to the inside of the top cover with a hole provided for the lens. A cut out in the split line between the two halves of the case provides access to the GPIO header. Two USB ports, the RJ45 LAN port, the SD carrier, the audio and video RCA ports, the micro USB power-in connector and a HDMI interface are all accessible through apertures of the correct size and shape in the sides of the enclosure. http://www.hammondmfg.com/1593HAM.htm#RaspPi

Three Things You Can’t Measure if Your Oscilloscope Doesn’t Have Enough Memory

Modern oscilloscopes come equipped with a host of different attributes, and many vendors tout their latest additions as “must have” features. With so many attributes and marketing messages, recalling the importance of a long-held attribute such as memory depth can become lost in the noise. However, any engineer who has grappled with shallow memory on an oscilloscope will be vocal about the frustration of the experience. Those who aren’t vocal simply haven’t stumbled on an issue that required it — yet.

Etching System Enhances NASA’s Device Fabrication Capabilities

VERSALINE® Deep Silicon Etch™ System Plasma-Therm St. Petersburg, FL 727-577-4999 www.plasmatherm.com NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, CA, recently installed a VERSALINE Deep Silicon Etch system to expand its silicon deep-etching resources. The new etching system targets silicon-based applications that include MEMS, sensors, and resonators. JPL’s Microdevices Laboratory (MDL) serves users with many different requirements, and the system’s mask selectivity, uniformity, vertical profiles, sidewall smoothness, and silicon-on-insulator capabilities will be used to meet their device fabrication needs.

CMOS Imagers Will Help Study the Sun in SoloHI Mission

CMOS imager engineering units SRI International Menlo Park, CA 650-859-2000 www.sri.com SRI International, working with TowerJazz (Newport Beach, CA), has delivered the first complementary metal-oxide semiconductor (CMOS) imager engineering units to the Naval Research Laboratory (NRL) for use on the Solar Orbiter Heliospheric Imager (SoloHI) optical telescope. With its large field of view, SoloHI will make high-resolution images of the corona and solar wind, and be able to connect remote sensing observations of the corona to the plasma being measured in situ at the spacecraft.

Solar Refrigerators Store Life-Saving Vaccines

NASA’s battery-free solar technology powers vaccine refrigerators in hot, rural communities. NASA’s photovoltaic (PV) technology has advanced many of its missions. This renewable source of energy is produced when certain photo-emissive materials, such as silicon, eject electrons upon absorbing photons from sunlight. These free electrons can be captured, and the resulting current can be used as electricity. NASA first used solar power in 1958 when Vanguard 1 was successfully launched into space.
