The skinny on the S.S. technology- new to DPS Pure Skis for 10/11. It's a game changer. With a Patent app in hand… the cat can now come out of the bag…meow.
The three basic goals in ski construction are:
1. Lightweight: skis move across your body instantly, quick changes, playful, and powerful creative skiing. less fatigue.
2. Power: reactivity, energy transfer, and responsiveness.
3. Vibration Dampening; better ride quality and stability at speed. silky smooth sensations and reduced deflection.
Pure Carbon unquestionably ramps and nails the first 2 over anything else built. However, in chopped, harder snow jazz, the reactivity of carbon for #2 can also work as detriment to #3.
Over the last year, we have been testing and building what we call the "S.S"- the special sauce.
The S.S. is a series of vertically laminated metal ribs built into the core that tie the upper and lower pre-preg carbon laminates together, and tune the ride into the silky smooth feel of a metal ski - without adding any weight or detracting from the sheer power of the carbon. It is the sweetness. We have toyed with different levels of metal and tuned it into an alchemy of metal dampening. The S.S. is Pure: Carbon+ Nano- now taken to 11. Super light, more powerful than anything built, and now silky smooth- ok, enjoy.
Cross Section with the S.S.
Torsion tester showing a a well endowed physical specimen: Pure versus a double metal laminate sled. 30% torsionally stiffer, 30% lighter.
Brilliant!

Brilliant!
Did it again. damn.
I saw that post of TGR too. Looks very smart. I bet profiling the cores would be a little trickier. Do you think the 13" planer/crib method is out? I would think the planer knives would be ruined where the metal strips were added. I guess you could get a bit that would do it with a router or on a CNC setup. Their skis are way cool.

I don't think my planer (Delta 12 inch) could handle metal. Maybe if you had carbide planer blades. I have a jointer too. One time I was running a board through the jointer and it hit a small wire brad nail. The blades got nicked. 
Wonder what the effects would be if you replaced the vertical metal w/ carbon fiber or fiberglass. I think that could go through a planer... Although I've never worked w/ carbon fiber. Definitely would need a vacuum hook up for the planer to catch the fiberglass.... a mask and safety glasses.... Anyone ever try that?

If they're using Titanal then it might actually be fine in a planer. It's just an aluminum alloy... HSS planer blades could be fine with, especially thin like that turned up on edge.
krp8128, did you post your thoughts on that up here? If so, it would be nicely dated prior art.

doughboy,
Where does your patent knowledge come from?
Prior art, properly documented and executed (i.e. you can;t sit on an idea, you must be activly researching and developing) can kill a patent in a hurry.
For example, had I documented this idea and performed continuous testing under my control unknown to the public* I could then produce skis using this technology. When DPS sends me a cease and desist notification, I can ignore it to the point of them taking me to court. Once I am in court, I use the "what patent?" defense, because my prior art would exclude them from ever having been issued a patent on the technology.
*i.e. I can't give you my skis for the day and say go ski, because you could cut the skis open and discover my work. There's a case involving mercury marine where a marina worker installed his idea in customers boats, mercury then went and "stole" it, he was screwed because it was in the public domain. I can look it up if anyone is interested.
This is my understanding of things from a patent course I aced last summer.
