Check out our Patent

It’s on the web!

The US Publication of our first patent is fully open for public scrutiny as of March 19, 2009. The international version of the same can also be found here. We are being brave now by filing internationally in all Patent Cooperation Treaty (PCT) countries, but sometime in year 2010 we would have to enter the National Phase in specific countries based on the market size. See if you can figure out how Figures 8, 9A and 9B work.

as a latte art fanatic i am concerned that this will only contribute to consumers being ruthlessly bombarded by advertisements…even on their drinks!! :( :(
it could also make hand poured latte art seem less impressive to coffee noobs…
it is an ingenious machine but i am kinda bitter :P

hmm, fig. 8, 9a, 9b. oh, you’ve got those HP optical mouse elements (several years out of date, i might add) in a triangular configuration around the printhead. wow. that’s interesting. perhaps you don’t remember that HP tried to build on the success of their handheld scanners (ca. 1993 in research) to build handheld printers (ca. 1996) but failed miserably for a variety of reasons. but i’m sure you guys have some secret sauce that will allow you to take the raw position information at low spatial and temporal resolution and reliably register the printout in this niche application. good f’n luck, chumps.

@terry: Thank you for actually going through the patent! Fear not, there is more than one way of doing this, and the fact that HP failed at some point does not mean they will not be successful in the future when it comes down to handheld printers. Can you elaborate on why HP failed back in 1996 (was it technology?) The sensors are getting better with every day. But I’m honestly delighted to see the breadth of knowledge!

[...] De prijs is nog niet eens bekend, maar er schijnen als meer dan 460 op de wensenlijst te staan. Er zelfs een patent op gegeven. [...]

Nice design! I wonder how using laser-mouse sensors can improve auto-tuning / calibration of reprap and similar machines!

But why not just use a camera / hough transform for the circular top, then use that as a paging technique and scan across like an ink-jet head?

The linear motion will be faster I think, and the output the same, and because the motion required is less complex, the motors can run faster without losing fidelity?

Just an idea! I love coffee, I love inventive minds – you guys rock!
