What ever happened to personal accountability in this country?! This is such a joke. Why wasn't this an issue when the hybrids came out 10 years ago? All of a sudden with the introduction of EVs, it's an issue. A complete joke.
I spent the last 4 days at the Detroit International Auto Show and there are more than a dozen PHEVs and EVs here. The Cadillac ELR (a 2-door sexy Volt) won a design excellence award for the best production car. Anyone doubting this electric revolution in the auto industry better figure it out quick. We're here!
If I'm reading this right, this is a really dumb idea. Make extra noise? Are you kidding me? How about we require the driver to blast the radio. What happened to "look both ways befor you cross the stret?"
I agree, Bill. There must be a more pleasant sound than the growl of an internal combustion engine. A few years ago, automakers were talking about making vehicles ring like a telephone. That never got any traction, though.
It is a bit unsettling how quiet these vehicles have become, and I guess one advantage of the noise is that you would know the vehicle is ready to go. It's interesting the a big part of the motivation is to make streets safer for pedestrians. What kind of noise becomes "standard" (if there is such a thing) would be interesting.
Much as I dislike noise pollution, especially from engines, I'm all for this. Those dang hybrid engines are too quiet! To get out of the driveway on my windy mountain road and go towards civilization, I have to either waste 5 minutes going down to the next side-street to turn around, or make a fast U-turn in the short section between two blind curves. I pick the U-turn every time. I can usually hear when a car's coming--but not lately, with so many quiet hybrid engines.
I think designers have an opportunity to make things amazingly better and safer while leading innovation rather than trailing it and reactivly responding to NHTSA regulations.
I'm a fan of the Toyota Prius, but why does the Vehicle Proximity Notification System (VPNS) use the sound of an internal combustion engine? For me the purr of a well-tuned engine is an attractive sound, not an alarm.
I say the VPNS should not use screeching sirens, chimes, or horn sounds, but what about the sound of a growling bear, roaring lion, or rattle snake? Since we are already instrumenting automobiles with proximity sensors on our way to autonomous vehicles, it should be a simple step to determine a probable pedestrian collision at low speeds and emit the sound of a sharp bark from a large dog -- the pedestrian's autonomic nervous system would engage way before they would make the conscious decision to look up from their texting...
Well, I guess I can understand the hazard and why this is a good idea to protect pedestrians. But at the same time, as someone who is sensitive to noise pollution, I think that it would be a GOOD thing for hybrids and EVs to be less noisy than gas-powered autos, not a bad thing. So I actually think it's a shame if something like this rule goes into effect. I certainly don't want people being injured or dying as a result of accidents caused by an inability to hear a hybrid car coming, but shouldn't it just be a sign that maybe people should be more present and pay attention when they're walking and in their every-day life instead of constantly being on the phone or texting or online on a mobile device. Food for thought, anyway.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
