re: Invisible bike helmet protects with air-bag shell

I bicycle, and I wear a helmet as all times. I like the helmet. I don't think I would go with the collar. I expect it to impede airflow around the neck/shoulder area. My helmet has ultiple vents. I suspect this is a solution looking for a problem that is already solved. I have crashed from time to time, and the helmet works very nicely. The helmet is much more visible to others and exudes increased professionalism. ...and the collar looks silly.

Peter, I think you hit the nail on the head. An automotive airbag only goes off on definitive (destructive) impact, as the immediate impact region on the vehicle is expendable. Can't do that with this helmet, obviously. I would have a hard time trusting some form of intelligent inference triggering that has to interpret the rider's head or other movement to decide when to deploy. And then, even if it can, if it fires a bit late and the rider's head is already nearly touching the ground, the sudden jerk of the bag popping in between the head and ground could cause far more harm than the actual impact.

"injector seat" reminds me of a certain segway-mocking episode of south park.

Having spent many years as a bicycle racer, I guess the thing that I notice is that probably my 2 most memorable crashes were sort of face-first into the ground. A rigid helmet at least provides some cushion to your forehead - this looks like a face-first impact would just push the hood back. But maybe that's not fair, I guess this is really meant as a helmet for people that won't wear helments (but for some reason don't mind a gigantic collar).

Well, you know, Peter, some people suffer for their fashion ;) It hurts to be beautiful and all that.... Also, motorcyclists like to live on the edge, so having a neckbrace filled with explosives can only add to their adrenaline craving lifestyle ;)

For me the bigger concern is the explosive nature of the air-bag collar. I understand that pilots that have used an injector seat are often not fit for service thereafter and there are anecdotal accounts of automobile passengers with facial brusing and even broken noses after the car's air-bag has inflated. So how would bicyclist feel about wearing a necklace of explosives? And would their hearing be as good after coming off their bicycle and having the air bag inflate suddenly?

I am wondering if it will really protect a motorcyclist in the event of an accident. Given that we are talking about moving objects (person/bike) hitting the ground or pavement, I must ask: Can the inflated helmet survive the typical abrasive impacts and still protect the head? I would be concerned that it would pop and deflate leaving the head completely unprotected. This would only give a false sense of safety and may hinder real helmets from being worn. I do think it is a neat idea but I would have a lot of questions about effectiveness.

Nice technology and an innovative idea...but practically thinking, it doesn't impress me much and I feel this is too much for a helmet. It requires battery as well, correct? or does it use some kind of energy harvesting technology?

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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
