what's the frequency range of a piezo crystal?
across this range, a pair of co-phased compression
crystals should be able to produce mono....now,
stereo is something else! 2 speakers required. -- j

don't you suppose that the feds are annoyed by
the competition? they would rather control us, with
no state- and local-level intervention, if they could
arrange it -- IMHO. -- j

this first 3 minutes -- mr. sound -- demonstrates
how crucial patents are for a small business. he
needs a ragnar danneskjold to protect his work
against unfair competition. -- j

Don't you mean Hank Rearden?

A mind-blowing product!
As to patents, when I was in the publishing biz, I found the copyright dep't (which is part of the patent office) to be indifferent to the point of disregard. Hopefully, he'll get his patents through in a timely manner. However, he might find it difficult once he goes into production to get his patents honored in Asian markets. To try to enforce them will cost a pot full of money and no certainty even if he wins.

Nice find, khalling. Worth the 5 minutes.

that is a product I would surly buy when it comes on the market.

It is a terrifically complex technology. The phase shifting and matching and speeds required to achieve any of what was demonstrated is amazingly difficult with piezo-electrics. I'd love to dig into one in the lab.

Not when I'm only 5 minutes from work. :) I love filling up only once every 3 weeks.

yes

I agree. It's actually quite amusing to hear about the JD taking a look. It's as if a guy from the Mob announced he is going to investigate why fellow members of the Mob are rigging the casino for the Mob to rake in the profits from the people. Think he'll see anything wrong here? Duh. Common sense folks... as if the JD is going to actually call out one of their own. It couldn't be more absurd.

thanks for that. I was sure big rocks were getting lobbed onto your car as you drove in to work

Don’t you think it’s a bit puzzling that the justice department is going to look at the militarizing of the police departments across the country after this administration has armed federal departments like the DOE? While I don’t like to see a militarized local group of law enforcers, I don’t want the government to confiscate anymore weapons to do what they please with either. They should clean house on the federal level first to show they understand the concern.

Hey back! Ah yes, the Ferguson fiasco. There was so much misinformation out there that I avoided getting into any arguments. Regarding the madness, I am exactly opposite in location of where they are at, so, all around me, Ferguson is faar away. Nobody was really 'caught up' in the MSM circus.

I was highly leery of the whole situation to begin with. It was another example of a "crisis" to exploit & pass BS laws/ordinances that ordinarily would never get past those pesky & annoying voters. When the news broke out that the communists & other Alinsky-eque "organizers" were importing fellow agitators to get the emotions of the MSM and other folks around the nations on high, I wasn't surprised.

Anyways, I've been gone for a while, the past two weeks being super busy with back to school activities & other little domestic-type inconveniences and annoyances. Missed you & the others!

HEY! why no weighing in on Ferguson from you? was hoping for some local viewpoint.

he had 14 allowed. the rest were applications, but many of them were design patents. Those are very limited and not about the tech, but the look. it is a complex technology by his brief description, you can look them up.

Wow. Just wow. Amazing minds out there. Do I think congress will do what they should? Mostly not :(.

40+ some patents on one product! That's amazing. I wonder how many are engineering patents and how many are use or application patents?

Very cool. Deep. We need more of these people...millions more. Thanks.
