Wonder if he was distracted (being in a rental car) and was not able to pay attention to his surroundings while using GPS. Not much detail in the story.
BEDFORD HILLS, N.Y. – A Global Positioning System can tell a driver a lot of things — but apparently not when a train is coming. A computer consultant driving a rental car drove onto train tracks Wednesday using the instructions his GPS unit gave him. A train was barreling toward him, but he escaped in time and no one was injured.
The way it works is that the saw blade registers electrical contact with human skin and immediately stops. I can’t imagine not having this safety system in place, now that it is available. However, I still have some questions that commenters might want to weigh in on:
1. Unless the system is more redundant than an airplane, it must be able to fail. How do you keep users to remain vigilant when 99.999% of the time there is no penalty for carelessness?
2. To answer my own question, is the fear of a spinning blade strong enough to do that on its own? I know I’m not going to intentionally test the SawStop.
3. Can we use natural fears such as this in other areas of automation?
“When do we as adult woodworkers take responsibility and understand the dangers of woodworking. Most accidents happen due to not paying attention to what we’re doing. If we stay focused while we’re using power tools, or even hand tools, we eliminate accidents.”
Verizon wireless interpreted an accessibility requirement to require they trigger a notification when the user dials 911. Verizon chose to do this audibly… exactly what you DON’T want when you’re calling the police during an emergency!
“The tone our customer experienced is our interpretation of Section 255 of the Telecommunications Act calling for a provider of telecommunications service to offer service that is accessible and usable by individuals with disabilities. The tone, indicating that 911 has been dialed, is one of several features designed to make wireless service is accessible and easy to use, especially for those with disabilities. Other features include a voice command key where customers can use their voice to dial by name or number; a voice echo feature so that a person who can’t see can hear the number or letter if sending a text; read back text messages and speech output of signal strength, battery strength, missed calls, voicemail, roaming, time and date.”
