I'm interested in this, but I know nothing about hardware stuff and I think this technology is furthermore undocumented. Do you know if the old waveform technology is documented somewhere?

EDIT: this is the only articles / documents I've found about the new technology that are a bit more detailed:

When a signal changes the state of a portion of the display from black to white, or from one gray level to another, the pigmented particles are accelerated to their new positions. Although the particles have very little mass, they must still be actively decelerated to maintain precise levels and sharp character edges. Regal is a new, more complicated waveform for doing this more precisely.

  • Temperature sensitive waveforms
If I've understood well, the wave is used to stop the vibration of the eink particles, and this of course depends on temperature. Indeed I noticed that Glo is much more slow at higher ambient temperatures. Do you know if there's a thermostat on Aura and not one on Glo? If so, I think it's not possible to use this technology on the other devices.
