Interesting tweet from a former uBeam employee: https://twitter.com/alexwhittemore/status/1441824887367032837 "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." This is interesting as I've not heard similar issues from other groups operating in this frequency range, or heard it myself. If true, I wonder if that was disclosed to investors or customers? Seems pretty important for general use and especially public spaces. |

For those of you who remember the IEEE Spectrum article on uBeam - Lee Gomes, the author, recently passed away. I'd gotten to know Lee and he was a great guy and journalist, sad to see him gone. https://spectrum.ieee.org/experts-still-think-ubeamrsquos-throughtheair-charging-tech-is-unlik https://www.legacy.com/us/obituaries/sfgate/name/lee-gomes-obituary?id=23371687 |
