A recent post by a former uBeam engineer made an interesting comment:
The biggest annoyance at uBeam was if the demo units were running when you took a call. The other side was always like "what the HELL is going on over there?" "Oh yeah sorry I'll go in the other room." The ultrasound down-mixes in the MEMS mic.

I'd posted before on the potential effects of ultrasound on gyros and MEMS, this is the first I've heard of uBeam affecting phones this way. I'm sure this information was relayed to customers and investors for them to take into account...
If that was Alex's biggest annoyance, he was ignoring everything else going on (and not going on) at uBeam.
