It looks like they've given up on things like efficiency, and turned to producing endless mis-shaped prototypes instead, those enclosures might be surplus from something else, plenty of ventilation needed to get 0.8W into a phone battery!
The good news is that with that rate of size reduction it will vanish completely in less than 1 year. :) :horse:

Tainted  comparison picture...   First prototype appears to be a "MEB", ie mostly empty box on the side view.  I'm used to seeing MEBs in marketing demos... Make the investor think they are getting something, or harvested from the local surplus yard are the big driver of MEBs...

EDIT:   latest proto looks three D printed, and those big vents are going to cause issues in a commercial environment.

More bragging on twitter.
New VP of Engineering:
https://www.linkedin.com/in/larry-starr-2328706/
And a whole host of new hires it seems, burning through the new cash in the pointless pursuit of ultrasonic charging  ::)

The attentive eye will note that they aren't the size arrays, so size comparisons are kinda  :palm:


I love that the size comparison has the largest enclosure open, showing that its mostly empty.

Looks to me like you could fit the largest into the middle just by switching to properly sized backplanes.

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.

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.
