Precision Thermometer Linearizes, Digitally Calibrates Platinum RTDs
Among temperature transducers, the platinum resistance temperature detector (PRTD) is generally accepted as the “gold standard.” PRTDs are available with interchangeability accuracies as tight as 0.1°C over operational ranges extending from... — Chuck Wojslaw , et al.

[Editorial]
Can Computers Be Made As Easy To Use As Appliances?
When I turn on my laptop computer, I typically hear a series of beeps and I see command-line sequences checking my system and eventually, bring me to an opening screen. The total boot process takes about two minutes, which in my humble opinion is... — Dave Bursky

Bob's Mailbox
Sir: Very good letter and comments about analog test equipment with knobs instead of pull-down menus (Electronic Design, Feb. 21, p. 133). Our company just bought a Tektronix TDS-3014 and I'm frustrated by the menu structure—But... — Bob Pease

[Viewpoint]
Hardware And Software May Be Destined To Merge
With the increasing demand for consumer electronic products, embedded-systems development—made up of both hardware and software components—will undoubtedly dominate the design world. Once this happens, codesign will again become a pressing... — Contributing Author

[Editor's Notebook]
Help Wanted: Those Committed To The Status Quo Need Not Apply
Eight billion CPUs will ship this year, but a scant 2% will be networked. With this as a starting point, speakers at the three-day Intel Computer Continuum Conference (San Francisco, Calif., March 15-17) urged the audience to explore options for the... — Stephen Grossman

[The Design Factory]
Multitasking Engineers Isn't Always A Bad Idea
Companies increasingly view the multitasking of project team members as a necessary evil. They do it, but acknowledge that they shouldn't. Because multitasking is seen as an obvious evil, we should examine its disadvantages and advantages.... — Don Reinertsen
