Wow, interesting problem to have! The first thought I had when I saw the headline was, "So, if you're in the Hell's Angels, you can use this particular computer?" Clever sleuthing on this one to figure out the problem!
Years ago an IBM typewriter field technician (so you KNOW it was years ago!), kept getting calls from an office where one machine seemed to malfuctioning. But when he tested it it worked fine. He even swapped out the machine, but still the one at a particular desk always seemed to malfunction.
So on one call, the secretary (so you KNOW it was years ago!). Showed him how it malfunctioned. She turned it on, put in a piece of paper, and the typewriter went into fits as her extremely full bosom rested on the typewriter keyboard.
My father was a shoe repairman in the San Diego area. He routinely added a braided ground strap to nurses shoes. They were required for individuals working in high oxygen areas to prevent sparks from igniting a fire.
He would simply take a flat braided wire and punch it through the sole and lay about a 1 inch length inside the shoe and outside the shoe and anchor the ends wth a flat rivet.
A secretary at a company I worked for several years ago would tell people not to walk by on the left side of her desk. One day it was me. When I asked why, she told me her computer would shut down. Not believing her, I asked her to save her work so that I could see if it was true. When I walked past on the left side of her desk, the computer did shut down. I checked to see why, and found an extension cord ran on that side, and the cord was losing connection with the receptacle.
Cabe - I had the same thought. Ground problems manifest in interesting ways. I once spent days chasing an ungrounded pin on an IC that produced a slight capacitive load with an 18 hour time constant that caused the output to exhibit a slight jump. If you need a ground - make sure it is a solid ground!
I was having a look at safety boots at our local work clothing store. apparently there are various specialties including high voltage insulated for electricians and anti-static for electronics techs. I asked if I could a combination of both. It took the guy about ten seconds to say no, that wasn't possible.
Jerry Weinberg (of IBM and "Psyc of Computer Programming" fame) tells a couple of stories:
The first one had to do with women operators having a high failure rate with early IBM mainframes. Remember, these were in carefully controlled computer rooms.
Turns out, the dress code required the women to wear wool skirts and nylon hose. The keyboards would happily conduct those big static charges right to the input boards. The dress code was changed && IBM later beefed up the static protection.
The other one was really weird. The mainframes would overheat in a random manner. Much wailing and nashing of teeth, because the AC and room design was IBM standard. Jerry gets sent to investigate. The operators were nuns, wearing full habits. He noticed a couple standing over the floor grates, then the system overheat warning going off. The nuns were just trying to get cool, but the full skirts were altering the airflow enough.
Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
