Now, because I've got a project called #TEOSS [gd0037] that will see me walking at elevated speeds, Moonwalkers inventor (a walk assist solution like TEOSS that's currently on Kickstarter) started to mine for a solution after almost colliding with a car on is scooter, and because this is a helmet which would be hard to transport in #TetInventory [gd0039], I'd very much like to know about and integrate safety features into TyMist. Just because certification is unlikely doesn't mean I shouldn't try and make projects safer. 

Initial expectations:

• High visibility
• Helmet needs to be secured by an under-chin strap when in transit to prevent it from falling off
• Shocks need to be safely absorbed.
• Helmet needs to be able to slide.

Initial mental simulation findings:

• High helmet diameter may result in higher moment forces on neck.
• A front crash may slide the visor out, causing it to only be supported on one side.
• The discontinuous edge between the cylinder and flat top face may be caught on rough terrain instead of allowing the helmet to slide across.
• The floor or collision object will initially be an impact, but it is most likely that I'd have enough momentum to slide across the floor afterwards.

    • Seems I'm thinking along the right lines with the 3 mentioned bullet points of CPSC.
    • Mental simulation result from implementing the understanding of MIPS:
      • "Wow. It works."
      • Expected moments on the head and neck have noticably decreased.
        • The fact that TyMist is a cylinder may already help in this regard.
      • A filleted chamfer on the top edge is expected to increase helmets ability to slide across the floor substantially.

      • The MIPS system may also reduce the forces felt on the head when rotating during normal virtual monitor use, and could even be a mechanical way of keeping the monitor view looking semi-stationary when turning to the next virtual monitor.

        • Sounds like they get speed gains from a flexible vat. Perhaps the #SecSavr Suspense [gd0105] could be faster than expected.
    • Simulation warning: Impact with nose on combiner
      • This combiner was already throwing a solution warning because of the fact that it's dark all the time. 
        • In an infinite possibilities world, the combiner would actually be a probably-non-existant pane that can be PWM driven between very reflective and very transparent, or some other way to electrically obtain different reflectance values.
          • Me, approx 180 seconds in the future: https://pubs.rsc.org/en/content/articlepdf/2015/sc/c4sc01912a looks to be the kind of thing I want.

          • The future is wow thanks to science! Liquid crystals can do so many things apparently.
      • I'm going to need to figure out how to move the combiner out of the way when not in use.
        • I might need to obtain a different solution if I ever install a PC into TyMist, but currently, there'd be nothing to see without #Teti [gd0022].
        • Perhaps the simplest approach will be to remove it from TyMist and hold the combiner inside a bag.
