Just the quick "executive summary" of that video:
Transmitter power density is quoted to be >1kW/sqm, actual transmitter is projected to be 0.33sqm (so ~300W).
A graph shows efficiency vs other methods, at 20% efficiency it lists 5W @ 1m, 1W @ 1.25m. At 60% efficiency it lists 1W@2m. No mention of transmitter power but the line seems to extend to 300W.
Theoretical projected efficiency quoted at 30%, current efficiency "much lower".
Applications are listed include data transmission and retail (user) tracking.
It's unregulated, OSHA dropped ultrasonic limits earlier this year as no adverse effects could be demonstrated. No effect on humans or animals. Most of the power is believed to be targeted towards the device and "99.9999%" reflects off the skin.
A vision system does the array steering, quoted mm precision and 30Hz update rate.
Business plan seems focused on IP licensing.
Most prior funding and future (this round) is going towards engineering and ASIC design. That's 26+20MM.
Final product, transducer, aims to be 100x thinner, 4x smaller with lower cost and higher power [density] than current offerings.
Those are the unbiased redacted quotes above. What caught my eye were a few small things: a big "transducer" sitting inside a car, close to the roof, as proof-of-concept. A low battery warning on the presenter's laptop. A group photo 51:34 that looks odd to my eye, like some people have been pasted in.
