Ann: Market Update - Progress Report, page-90

I asked Yuval specifically at the AGM about the current status of both structures. They are only working on the partial structure for the demo. It is sufficient to be considered a breakthrough in sound technology and is easier/cheaper to develop. They will continue to work on the full structure device once they have the initial product in production.

It needs to be remembered that the partial structure was an accidental invention, that produced results far beyond their understanding of what was expected. Through further research and the new modelling software, they now understand exactly how and why the partial structure works and in the lead-up to production they will continue to make tweaks to maximise its performance.
