I believe that the Myer Burger equipment was used to "brick" the boules. These were then sent to China for wafering, polishing and final sizing. The Hyperion system was intended to exfoliate thin slices of Sapphire...probably as part of a next gen product like in their laminated window patent. Hyperion's advantage was that it could generate very thin sheets of sapphire with essentially zero waste as with the saw kerf in wire sawing. Each face had to be final polished but the starting point was closer to the end quality that the saw cut finish.
Apples may have been trying to refine the process in Mesa in parallel to the Chinese activity.
I think that Takatori was the wafering saw supplier vs the bricking from MB.
