Methinks the large one was a former  case from a certain brand of large laser scanning confocal microscope and held a bunch of Eurocard modules.
If not that, it's structure  certainly was done by the same design team.

The good news is that with that rate of size reduction it will vanish completely in less than 1 year. :) :horse:

I hope the keen investors are suitably impressed with uBeen's recent product launches, and all the revenue they're now generating. :)  :bullshit: :horse:

"uBeam transmitters are designed to sit discreetly in any location without calling attention to themselves and without disrupting style and flow. A uBeam transmitter might sit on a bookshelf or coffee table in your home appearing no bigger than a book or coaster. In the office, warehouse or complex, transmitters could be strategically installed under desks, on the wall of a conference room or next to a cabinet in a break room. "

Without calling attention to themselves is the new company moto....

The only thing they have of any value is the transducer IP, which I have been very reliably informed is worth a pretty penny.
If they are the least bit smart, uBeam can keep the Titanic afloat for a lot while longer.
Of course their silly charger tech will never work, for many blindingly obvious reasons

By an investor :), I can't think of anything that isn't already done.

45Khz, 125dB and your laptop is dead (not because the battery is empty... the hard drive and the OS ...)

I find it interesting that at such a high vibration level they are still only fooling the protection sensors, and not directly screwing up the ability of the heads to work over the disk.

I think some of uBeen's cartoons show laptops on desks, with the US TXs built into the surface of the desk. :palm: :horse:

Since it's behind a paywall, can you summarize?

Seems like they should be studying uBeam's employees.

Or the beta testers in Cuba and China.

"Since it's..."

If I google the 2nd half of the url I can read it in the first link(News for...).
There's not much there, US beams mixing and producing LF, and the embassy sicknesses.

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.
