"export DxO as a jpeg and then open with PS"

Blasphemy!  If Thou intend to further edit in PS then Thou shalt export in a lossless format!  Be this the proclamation!

Your grammar is worse than blasphemous: Thou intendest, not Thou intend; to edit further, not to further edit (no split infinitives are to be found in the works of Shakespeare, Spenser, Pope, or Dryden, or in the King James Version of the Bible).

Fair enough  :P

Good sport! And I agree that for serious editing lossless is better, but I usually do minor stuff in PS.

No worries.  Great jab back at me :D

DXO is not really a full featured editor, but it does a excellent job of converting the raw image, and doing NR.  Uploads to sites like Smug Mug were not supported when I tried it, it does not have a full featured print module, and a lot more.
Lightroom has a lot more tools that can be used to actually edit the image, and in particular, a often overlooked organizer.  Once you get 10's of thousands or hundreds of thousands of images, you will need to be able to find the ones you want.

Definitely.  I was just joking around that AlanF said he exported from DxO as a JPEG (lossy compression) and then reopened in PS for further editing.

Does the comment from Northlight that the patent doesn't show any pixel structure make sense?  If it's a layered (Foven type) sensor then there wouldn't be any "pixel structure" per se.
I was referring to there being no details of the internal structure of the light sensitive regions, or positions of wiring interconnects and the like.

Compare it, for example, to the Canon patent drawing I linked earlier.  This one is very much a block diagram - although I like the assorted boxes and stuff on the underside, to suggest a BSI sensor...

Ah ok, got what you mean now.

the blue pixels would register the blue photons and the red pixels would register the red photons just like our eyes do.

No, sensels seperate wavelengths relatively sharp via filters, while L- cone cells are still somewhat sensitve to short wavelengths; akin to the spectral response of a Foveon sensor.
Take a sample of cobalt violet for example, light reflected of it as no spike in the red band, it absorbs red light about as good as black.

Technically true, the response curves of our cone cells do not have sharp cut-offs but please define "somewhat sensitive to short wavelengths"... if by that you mean "close to zero" then you are right.  If you observe short wavelength light your L cones register a tiny response but the response in the S cone would be orders of magnitude higher and your brain would register that as blue light.   Similarly incident light that is green would cause a response in all cones almost equally but your brain knows that is green, rather than white because of the relative responses to blue and red components.

Our brains have to be more complex to deal with the overlap and larger range of response patterns but that still does not mean our eyes, or a sensor, would be confused by UV light.... your eye simply will not see UV light as purple... our visual perception of "visible purple" is NOT the observation of near UV light.

"Red/blue blend" and "shorter wavelength than blue" doesn't quite jive... can you explain further what you mean?

"now the violet hues the camera mistakes for blue"

Except that the human eye works in a similar way as an RGB sensor so your eye would make the same "mistake" and therefore it wouldn't be a mistake relative to our vision.

I believe (I'm no expert) the fact that humans perceive a mix of red and blue to be "visible purple" is not the same thing as observing light of a "violet" wavelength.   If you look at an object and see it as purple it actually is preferentially reflecting red and blue wavelengths of light.  Therefore an RGB sensor would not be confused by that... the blue pixels would register the blue photons and the red pixels would register the red photons just like our eyes do.

I wonder if this could eliminate the need for IR conerted cameras?  Maybe with this sensor you could only record the light from one of the layers.   
I know this is a small market and not at all likely the original point of the sensor but it could potentially be a happy side effect.
it certainly could - while it's a small market - the ability to flip a sensor and shoot strictly UV or IR or a combination - would be incredible; and there's more converted cameras out there than some give credit to.

Not likely.  IR or UV converted cameras typically filter for just IR or UV in order to get unique images based just on those wavelengths that we can't see.  The images are "false color images" with the variation in IR (or UV) mapped back to visible wavelengths.   I would suspect that this new 5 layer sensor tech would not be designed to pick up wavelengths too far from visible... rather, just extending slightly into the IR and UV in order to use that information to improve color rendering at the edges and possibly correct better for color shifts and other optical anomalies.

This is likely to mean very near IR and very near UV, and thus existing lenses would be okay.  Far UV would be removed by the glass, as would far IR. 

Very near would be enough to solve for example the purple/violett problem, i.e. colors that would be represented as a red/blue blend in RGB, but due to being of shorter wavelength then blue only register on those blue sensor cells and shift colors.

"Red/blue blend" and "shorter wavelength than blue" doesn't quite jive... can you explain further what you mean?

Don, this is going to be really a meaningfull innovation when an actual product will hit the shelves ... untill then this remains only a patent.

It still represents a commitment to R&D, which is important.  But not everything you throw at the wall sticks.

Fully agree.  It shows Canon is working on next generation sensors.  On the other hand, real products matter and many large tech companies file a lot of patents defensively so that no one else can develop a product and then sit on the technology rather than invest in developing real products.

CL works but as said above be realistic with how much you ask.  Your used gear may not be worth what you think it is.... in other words it's used and has no warranty and therefore is worth less than what new with warranty or refurb with warranty is going for *today*.... for example what you paid for it 3 years ago from your local camera shop when Canon just released it is irrelevant now.  Seriously I see people posting used flashes for example and stating "Two years old, lightly used, was $600 new, asking only $450"... meanwhile a brand new 600EXrt is for sale at the local shop or B&H for $499 or less.

And yes, always state in your post that you will only sell local and for cash.  And stick to that.

Oh Neuro why do you bother.  You just can't help some people.

Such a typical post....  the logic goes something like this.... "people are complaining about X, I don't have a problem with X, I'm a good photographer, therefore the people complaining about X must be bad photographers and should learn to use their gear better, I think I'll post on CR about how awesome I am"

Rights are superseded by social responsibility.

I get your point, but you're overstating it.  Rights can not be superseded... otherwise it wouldn't be a right.  But there are limits to certain rights... you have the right to free speech but that does not include inciting a riot by falsely screaming fire.  It also doesn't include harassing people.   Similarly, taking photos of people in public is not prohibited (and this has been held up in court cases I believe) but following someone around taking photos of them day after day could cross a line into harassment.

Definitely a good idea to speak to the coach and/or other parents before hanging around a ball field or hockey arena taking photos of kids.   Even better, if you're just looking to practice sports photography shoot a men's league and still let them know who you are... they might even buy some photos :D
