Each week, the editor of Planet Analog finds items of interest and then features them in two sections, entitled “Also of Interest” and “Elementals”. Each cites items from publications outside the Planet Analog and EETimes portfolios. And we also have an archive of recent weekly Planet Analog Newsletters, as pdf files; see the list at the very bottom.
“Also of Interest” and “Elementals” is an extension of our belief that engineers are interested in on-going tutorial on obviously relevant topics, as well as the serendipity of exploring topics which are not directly related to their jobs, but which will broaden their knowledge and sometimes spurs innovative and creative approaches. The first box highlights items of general interest to the engineer, while the second highlights basic and tutorial electronic-engineering material. Among the publications we check are IEEE Spectrum , Machine Design , Design News , Laser Focus World , EDN , Electronic Design , NASA Tech Briefs , Microwave Journal , RF & Microwaves , and Physics Today , plus others.
Consider these items as online extras, and worth a look. (Please note: there are also links to the previous weeks' editions, in the “Navigate” box to the right.)
Also of Interest:
- A straightforward procedure can guide designers toward the right motor for common uses:
“Motor Sizing Made Easy,”
Machine Design , March 3, 2011 - By taking into account the “volatility” of optical dispersion, optical materials can be combined to create a single refractive lens system for imaging across the visible and infrared, or disparate subsections within this range:
“Ultrabroadband optics image from visible to longwave IR,”
Laser Focus World , March 2011 - This transducer could ensure better testing of off-road vehicles:
” Wheel Force Transducer,”
Defense Tech Briefs , April 2011 - Inject thermal filler material (a paste-like substance) inside the power wire bundle coming from solar array, to fill in voids between wires, and enhance the heat path and reduces wire temperature:
“Thermal Control Method for High-Current Wire Bundles by Injecting a Thermally Conductive Filler,”
