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.
“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 a few items of general interest to the engineer, while the second highlights some 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 , Portable Design , and Physics Today , plus others.
Consider these items as “online-only” extras, and worth a look! (Please note: there are also links to the previous weeks' editions, at the bottom).
Also of Interest:
- Alignment of electro-optical devices with multiple paths, multiple sources, off-axis elements, tight tolerances, or difficult components can be simplified through well-known tools and feedback from optical instruments:
“ELECTO-OPTICAL DEVICES: Novel methods simplify alignment of complex electro-optical systems,”
Laser Focus World , November 2008 - Someday, chips might be made with X-rays. Until then, double-patterning lithography will be the only game in town:
“Seeing Double,”
IEEE Spectrum , November 2008 - Besides the memory, there are only two key ICs in the design of the frame:
“High-end digital frame comes from relatively simple design,”
Embedded Systems Design , December 2008 - Both the practical and the funky benefit from rapid-manufacturing techniques:
“Custom Manufacturing Grabs More of the RP&M Market,”
Desktop Engineering , December 2008 - This method would enable safe transport of a biologically hazardous sample.:
“Sealing and External Sterilization of a Sample Container,”
NASA Tech Briefs , December 2008 - The Times Square ball will this year double in size, get three times brighter and become a year-round installation:
“New Year’s Eve Ball Grows Bigger and Brighter,”
Design News , December 12, 2008
Elementals:
- The author describes how signal measurement has progressed from basic spectrum analysis to a combination of frequency and time domain analysis, including modulation:
“Evolution of Broadband Signal Measurement and Analysis,”
High Frequency Electronics , November 2008 - In the interlaced frame integration operation mode, there is no binning. In the first field, only the odd lines, and in the second field, only the even:
“Interlaced Goes Digital: Combining Interlaced Sensors With a Digital Interface,”
NASA Tech Briefs , December 2008 - DSL equipment requires protection from a variety of overvoltage conditions, but the need to avoid unduly degrading circuit operation complicates circuit design:
“Designing protective circuitry for DSL loops: Beware of pitfalls,”
EDN , December 5, 2008
