This is a fantastic story George! It is always surprising to hear about some of the oversights that happen out there, especially in the medical industry. You'd think there would be some kind of additional level of scrutiny, but I guess theres not. It isn't going into space after all.
I love the fact that you say that your idea was "just good enough to work." I think that's one area that all engineers can never get enough experience, which is "Determining when good is good enough!" Quite a trial by fire for a new engineer!
Nice story. Sometimes there are some of these design flaws that somehow escape unnoticed while design phase or reliability testing phase. I remember some of nokia phones bursted or produced lot of interference when in gas stations or phone kept on charging and at the same time talking on the call.
Great story George. I used to maintain a fleet of big old CRT terminals, with analogue power supplies, and power supply connectors were my # 1 problem. The board connectors just had a circular pin, a blade pin as in the old AT power supplies w=is a much better idea,
And a good fix too, glad you got some recognition for it!
@kfield: Wow David, maintaining a big fleet of "CRT terminals" almost sounds Dickensian today!!!
What makes you think it was a "big fleet"? (Are you projecting again?) What David actually said was that he used to maintain "a fleet of big old CRT terminals" -- which leaves us none the wiser as to whether it was a small, medium, or large fleet.
I'm sorry -- I can't help it -- I am an anal retentive engineer LOL
PS It's not the size of one's fleet -- it's what one does with it that counts :-)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
