This should help prevent accidental injuries and hopefully there is a measure in place to prevent tampering of the safety device. This article should be tied into the common sense article. Safety is only as good as the person using the tool.Engineers can always design safety into the equipment, but in the end it comes down to the operator.
This important safety story reminds me of seat belts, shoulder-harness seat belts, and air bags. All of those developments were around years before they were widely adopted. Of course, as you point out here, there's a little bit more involved in terms of retooling. Still, you'd think the prospect of spare digits (not to mention, prevention of deaths) would be something that'd get customers crying out to the vendors to implement this great feature. (Everyone should see that video.)
The question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the countryís worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If youíre an embedded systems engineer whose analog capabilities are getting a little bit rusty, then youíll want to take note of an upcoming Design News Continuing Education Center class, ďAnalog Design for the Digital World,Ē running Monday, Nov. 17 through Friday, Nov. 21.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
