According to anthropologists ax was invented in different parts of he world that had no known connections simultaneously in historical sense. Materials were used different, but shape was similar, butterfly wing-like. It reminds me Popov and Marconi, for example.

In such case everything would be named differently, and you had to apply negative voltage on collector of NPN transistor. Wait, it would be called PNP! Holes would be negative, electrons positive. Arrows would be drawn to the same direction as now!

They took it off the tour because they considered it "Secret" and so would not show it to anyone who might actually learn something.

Then decades later I was at JBL in the their large testing room, waiting for my friends to come back from a not so quick bathroom break. One of their engineers who did not know me wandered in and stood around looking nervous. He wanted to measure the deflection of an enclosure, but did not want to do it in front of me, as he though it was "Secret" stuff. My buddies got back and laughingly explained that it was OK to do it in front of me as they had just been demonstrating that system to me.

These days you just buy a Klippel analyzer. It is a nice and moderately priced system.
Companies. Sheesh!

When Brendon S. decided it was time to look for a more promising career path, he discovered that Harman was looking for a chief engineer in the Multimedia group (I believe at that time it was known as Audio for Computers). So he applied, got interviewed, got the job. Upon his first day at work, he arrived, and so did a giant package of a lawsuit from his former employer Labtech. It turned out among other things that Tom Jacoby had secretly promised Labtech in writing that Harman would never recruit anyone out of Labtech, so that was one of the complaints. But of course Harman didn't do any such thing. But the lawsuit proceeded, depositions, great expense, yada yada.

In court, attorneys for Labtech mentioned all of the crucial proprietary material that Brendon had been privy to. Among the things they regarded as very valuable and to which Harman must be prevented access: the virtual multi-axis surround synthesis technique invented by Duane Cooper and Jerry Bauck.

There was a huddle. The attorneys for Harman came back and pointed out that VMAx was licensed to Labtech by Harman.

That was, one could say, something of a setback for Labtech.

Sounds about right...

We used to measure .001" (25u) electroformed orifice plate holes (5,000 holes in a 4 foot nickel plate) all to 250 nm with a travelling laser on a track. Controlled size to ~ 1.5% for accurate high speed inkjet dye printing on fabrics; this was ~ 1980 or so. Counted the edge produced interference fringes.

Well, Benjamin was an excellent observer of lighting strikes, so he assumed what he saw was correct..and he got it wrong. bad coin flip on that one. Remembering that the ground is the source is always a good way of thinking when trying to grok the functionality shielding. Almost like dither, in one way of thinking. A covering noise for obscuration as opposed to shielding/blocking via absence or drain. Like a fish living in water, it is a reference for zero even though it is the exact opposite of that. Relativity comes to life in a ground reference. (just rambling out loud. You'se no dummy Scott, I'm not aiming anything at you)

As for the rest of my original post, here's a recent proofing. One of thousands, if one bothers to look.

http://www.nanotech-now.com/news.cgi?story_id=44551

Electric universe, elastic and mutable via loading and shift/delta. This involves extreme pressure and speed cutting jet designs:


This technology can be used in sectors such as photovoltaics, microsurgery, targeted delivery of drugs, micro/nano fabrication and low cost extraction of algae for biodiesel production.

The founder and CEO of Nanospire, Mr. Mark. L. LeClair examined the cavitation machining for jets in early 2004. He found a crystalline form of water created by cavitation. The faceted jets had enormous electrostatic charge. By applying electrostatic charge, the crystalline jets etched lengthy semi hexagonal trenches which resulted in increased removal of substances.

The crystals were accelerated due to their attraction towards the supersonic bow shock produced by the Casimir Force. This acceleration resulted in the relativistic speeds of crystals in extremely short distances. This phenomenon was called the LeClair effect. High elemental transmutation was witnessed due to the bow shock.

Using the patented LeClair effect, Mark LeClair produced a cavitation reactor in March, 2007. A hot water heater was a result of the experiments carried out during mid-2009, funded by a low energy nuclear reaction (LENR) advocate. Mark LeClair along with Serge Lebid, co-founder of EVP and Five Star Technologies, found that the reactor activated high transmutation, fission and fusion in water. The reactor heated 2.9kW of water by utilizing 840W of input. The output was 3.4 times higher than the input. While passing through the reactor, the temperature of water increased up to 32F with temperature spikes of 50F. The experiment was repeated 12 times.


78 different elements were detected.

A lightning bolt differs from a spark. The lighting is a series of discharges and what the eye sees appears to be a single bolt. But if you understand why a lightning rod works, that is because it really does start from the ground up! But the localized energy storage is in the cloud. So once a path is formed the charged water vapor does discharge downward.

Now I watched a PHD defense on the propagation of sparks. It was quite interesting. The field between the electrodes propagates as a spherical wavefront until it reaches close enough to form a discharge point. This then ionizes the nearby gases increasing a local conductance area. That is the flash you see.

Did not Labtech become Logitech?

It's a convention there is no right or wrong.

I assume they repeated their own experiment.

They were acquired by Logitech and dropped the brand name. That occurred quite a bit later.

Brendon, after a power struggle at Harman, was shifted to a marketing-oriented position. He was still more recently offered a job by Altec as the latter had just started up a facility in San Diego, and I believe he is there now.

A good guy. Straightshooter, fair and just, and not a glad-hander. He was my boss for quite a while when I consulted for Harman Multimedia.
