I know you all desperately want to hear a Perry interview:
https://makeitinla.org/podcast/meredith-perry-ubeam/

Hmm, about 31:40 she says the first time they *ever* charged a phone wirelessly (and that she saw it do so) was Dec 5th 2016. Hadn't they been claiming they were doing that way before then?

Some takeaways...

There's still no independent demonstration of how fast it charges a phone, which remains the key use case for her technology.

The transducers are operating at 40kHz, and they're manufacturing them themselves in their own facilities. Apparently they have improved the efficiency particularly at the receive end, but no numbers were quoted.

uBeam won't be manufacturing or selling completed units themselves. She talks about a "reference design" and that the technology can be licensed.

Q. "Are there any uBeam licensees?"

A. "Can't answer that".

I have heard that the efficiency is exceptional compared to commercial units, in theory. But in practice getting yield is proving a problem. They need a LOT of these units.

No one will be dumb enough, except perhaps in very niche areas. The consumer space for this was dead out of the gate.
The problem  is they won't ever pivot with Perry at the helm, she staked everything on the mobile phone application, she will not want to admit defeat. She'll go down with the ship before admitting mobile phone charging isn't practical.

The company is ramping up to manufacture millions of units and will ship a product by the end of next year, said Perry in a September interview with the Business Journal. Perry previously said uBeam would be available in fall 2011 and also in spring 2013.

And now it's never, if only anyone had tried to warn the investors. :palm:

40kHz is definitely not pet friendly.:horse:

Wow, she's such a fake and boastful. Something's very very wrong with this world.

Furthermore, in the interview she criticised other wireless charging technologies like Qi because the device won't charge while you're using it, which I found more than a little ironic. How does it charge when you're holding the phone while taking a call, or using the touch screen, when the energy harvesting transducers are covered by you hand or face down on a surface?

I wonder how the journalists never pick up on those things and never ask the awkward questions.

They don't even need to be tech questions or use the word "efficiency", you could simply ask, "How will you ever convince Apple to add 2cm thickness to their phones?"

I get the feeling she only does interviews with the known-gullible. None of us would ever get anywhere near her.

There are lists of journalists who are known to ask 'awkward' questions, that circulate privately in the PR world. You can, in part, judge a company on whether they ask their PRs to not invite people on those lists to events. Despite all their other sins Microsoft (and their UK and US PR firms) DO invite journalists whose names have found their way onto those lists.

Now that is a list I would like to be on  ;D

I do like the way she besmirches the reputation of those who have left the company. Stay classy uDream!

Just hold your phone naturally, using two of your left hand fingers, stand to the side of the beam, and make a nervous hand gesture using your right hand.

Now hold that position for 3 weeks, and voila, your phone is all juiced up and ready to go.

The other version of that is "I saw him coming from a mile off", which is do doubt what the salesman who sold him that jacket said as he was taking his commission.

uBean are very quiet, have they closed down yet. :)

liesandstartuppr.blogspot.com   has done some calcs on Energous's 915MHz wireless charger, giving charging power efficiency of 0.2% to 0.06%.
One day all batteries will be wirelessly charged this way. :horse:

I should pay more attention to Paul's blog. I haven't read in any detail the FOI documents, but the general tone seems rather bizarre.

o Energous seem to be using the FCC as a consultancy service.
o From the tone of his emails, SVP Jeff McNeil appears to be overly sickly sweet and sycophantic in trying to cosy up to the FCC.
o How have they managed to get such a direct relationship with the FCC?
o Jeff McNeil starts off as SVP Operations, then automagically during the FCC "consultancy" becomes SVP Operations and Regulatory, but I see no evidence that prior to this he had any experience of FCC regulatory issues.
o Jeff McNeil appears to now be working at Enphase Energy since January of this year.

Nope, they just moved to a new 12,500 sqft facility that will handle the hazmat issues they have.
They have lost more top staff. The new COO Kostas Mallios lasted only 9 months.
https://www.linkedin.com/in/kostasmallios/
He apparently bailed before his 1 year option vested, so I guess that tells you something.

For those wanting to play around with ultrasonic phased arrays, this open access paper and toolset might be of help.  It seems pretty comprehensive and the team that worked on it at Bristol University are well respected.

https://ieeexplore.ieee.org/document/8094247/

Quote
The system hardware consists of a driver board capable of reading the amplitude and phases produced by the software and then generating half-square wave driving signals of up to 17 Vpp and π /5 phase resolution for 64 individual channels. Up to 15 boards can be chained to increase the number of channels. A set of 64 phases can be updated 25 times per second. For complex and fast field modulations, it is also possible to upload onto the board up to 32 phase patterns and a script that exactly specifies how many periods each pattern should be emitted.

For a wide uptake of Ultraino, we provide source code, components list, PCB designs, as well as video instructions for assembling the board and example arrays for applications in particle levitation, mid-air ultrasonic haptics and parametric audio (Supplementary Movies and https://github.com/asiermarzo/Ultraino). A PC running the software, driver board, and an array are shown in Fig. 1.

Not sure what the phrase "π /5 phase resolution" means. Can someone explain?
