Sadly, you only reading one side of the story. Joe is the most

Ruthless at times? Yes, indeed! But the crime rate is wa-a-ay down,

(*) A hefty portion of the crime source. Remember, this is ARIZONA,
on the border, drug traffic like crazy, and Obama and
dumber-than-she-is-ugly Napolitano ignore the problem... they consider

arrests illegals.

Bloggsy should come for a visit, and meet Joe face to face.

The Maricopa County Board of Supervisors this afternoon voted
unanimously to approve a $3.75 million settlement for New Times'
co-founders, whose false arrests in 2007 were orchestrated by Sheriff
Joe Arpaio.

Was ACLU involved?

I'm sure they hate Arpaio for political reasons.

How is it that Arpaio is guilty of all
of that and no Judge or court administrator
took action or bears any responsibility?

You would think this provides more than adequate ammo for his would-be
opponents to displace him, yet he keeps being re-elected to office.
On balance, enough people think he is getting it right enough of the

Technology Advantages

10x Power Density
At VHF switching frequencies, energy is processed more often, so it can be handled in smaller chunks. This means less temporary energy storage so the inductors and capacitors can shrink. Since these energy storage components occupy the bulk of the volume, the direct consequence is reduced converter size—up to 10x—and higher power density.

Amazing Transient Response
Transient response reflects how fast a power converter can adapt to changes in the load or source. FINsix converters are 1,000x faster than today’s technology. This makes life easier for system designers and enables unexpected applications, like best in class dimming and compatibility for LED lamps.

Rugged Reliability
The elimination of heavy components, like magnetic core transformers, enables superior resistance to mechanical shock and vibration. Furthermore, the overall reduction in component count, specifically of through-hole components, means fewer points of failure.

Batch Manufacturing
Since we don’t need discrete inductors or other through-hole components, our power converters can be manufactured in a fully automated surface-mount process, ensuring high reliability and repeatability.

However annoying patents are, these things are always patented, and

There's two schools of thought regarding patents with my energy
extraction clients. One school believes that patents are better than
nothing to protect a new gadget. The other school believes that patents
only reveal the inner workings of a new gadget to pirates. What one
believes seems to hinge on what happened to one's father.

In the former case, the father-in-law of one my clients invented a new
gadget and did not patent it. The inner workings of the gadget got
ripped off soon after it hit the oil field.

In the latter case, the father of one of my clients got ripped off by
pirates who used the father's patent as a blueprint. So the son did not
file a patent on a new invention. Instead the son housed his new gadget
in a virtual vault made of steel.

Black box virtual vaults (that are not always painted black) are common
in the oil field. One client suspected that a black box rented by him
contained little more than a PC. But the "if we detect that you opened
our black box you own it" clause in the rental contract along with a
sky high sticker price kept the enigma intact.

That sort of arrangement is best, where possible IMHO. If you can
keep your device secret, keep it secret. That costs nothing, needs
no paperwork, has no fees, and never expires.

But, that doesn't work if you're selling something with a clever
circuit that anyone can take apart and understand.

RCA profited mightily from its guerrilla hold on radio patents. So
"General" Sarnoff reckoned that RCA was entitled to own all of the
newfangled television patents too. But an unknown named Philo Farnsworth
invented television first.

That set up a "David versus Goliath" struggle, but instead of a sword
the Goliath named RCA wielded a bunch of off-the-wall patents.
Apparently the "General" thought that, "If you can't dazzle them with
brilliance, baffle them with BS!" Unfortunately this time around Goliath
used its legal might to win by dragging things out in court until
Farnsworth's patents expired.

I don't quite understand that last bit. IIRC, patent damages would
still be collectable on the pre-expiration period of infringement
even after the patent expired.

Cheers,
James Arthur

Really, I have one Cree flashlight (from ebay) that is single button, can flash and dim, variable focus, ultra bright beam (do not look into it),
3 other flashlights, for car, house, etc, also LED.
One LED light in the bedroom on 230 V,
Color LED strips in the living room window pane with my own color controller, controlled from a PC:
http://panteltje.com/panteltje/pic/ethernet_color_pic/index.html
and none make a noise, and all of that comes 'on' the moment you switch it on,
the LED strips can be modulated by music in color and amplitude.
You can get 230 V LEDs here at the supermarket, they are getting cheaper too,
some have a remote control I think for 'on' 'off' and color,
and have labels indicating power consumption and light output.

What do you think the odds are that
FINsix will make it to 2015?

Well the CV of some of those great people may mention they worked on the most advanced power technology ever invented and patented by MIT <insert professor name>,
when presented on the *next* website.

Last night I did read up on PC ATX power supply efficiency, the current 'best of the crop',
and that is something like 93% (for 400 W at full load and 50 % power level).
http://www.plugloadsolutions.com/80PlusPowerSupplies.aspx
click on 'what is 80 PLUS certified"

To be better they will at least need 95 % in their converters.
At 60 W 5 % is 3 W, and 3 W in that small housing they have will get bleeding hot.
So 98 % would be better, but it looks like they still use a diode bridge, still need
mains isolation, absolutely need mains RF filtering, and output filtering (inductors!),
so and those things have losses too.
And the 230 V version.

ebay is full with LED and laser diode drivers.... small PCBs....
As they say, waiting for their products, do not hold your breath.

It is not that surface mount makes the thing more resistant to vibration and shock.
In fact the slightest bending of a surface mount board will cause disaster,
the old resistors and caps with wires through holes
would keep working when the board bended.
It was an old mil requirement that wires had to be through holes in pins and folded around those some times
and then soldered....
Not sure that still goes.

Standardizing on something like a micro-USB is just the first step. Even
with the proper adapter cable, try to get Apple, Motorola and a bunch of
other models to actually charge just because they see +5V is a crap shoot.

Motorola won't play nicely with an Apple USB wall wart. Apple won't play
nicely with Motorola. Neither will charge off a Kindle supply. It's a mater
of how the wall wart and load implement the handshake for charger capacity.

Good luck getting that to work across vendors. The best attempt I've seen is
a 12V power port (cigarette lighter) charger with 'Apple' and 'Everyone
Else' ports.

No, 5V is just fine. USB is the question mark. The "spec" isn't
enough to charge something like an iPad in a reasonable amount of
time. Even a cell phone is really pushing it at a half amp.

Motorola won't play nicely with an Apple USB wall wart. Apple won't play
nicely with Motorola. Neither will charge off a Kindle supply. It's a mater
of how the wall wart and load implement the handshake for charger capacity.

It's not an "implementation of a handshake" at all. The decision
about how to charge is made by sensing resistors on the device. If
they're not there, the normal USB handshake goes on. Of course, USB
limits the charge to .5A. Some *chargers* don't like the load up to
that point.

Good luck getting that to work across vendors. The best attempt I've seen is
a 12V power port (cigarette lighter) charger with 'Apple' and 'Everyone

It's done all the time but only if this is a requirement of the
charger. MicroChip has some interesting solutions for this.

There might be some reactive (inductive) power flowing through the auto

Changing the tap settings and more and more power will flow through the

Actually less power, for a constant load, since the voltage reduces.

Derive an expression for the voltages and currents in an autotransformer
tapped at, say 30%, hence the flux. Neglect winding resistance.

Since you seem disinclined to do that, I'll ask this:

As you rotate the variac, moving the wiper from 100% downwards, does the
phase of the output change, or stay in phase with the input?

Try it.

That should tell you something.
