Geez, how the heck do (did) they do that? As far as I know, vibrato
is not a consciously controlled thing, so you can't sync it. I
wonder if it was done by running their voices through a MIDI-Verb
in the production process?

Everything's consciously controlled, to some small extent. By
concentrating, I can reduce my heart rate. Sometimes. I think.
There's a few people with the proven ability to do things like control
heart rate (up and down?), basal metabolic rate (let's go sleep on Mt.
Everest without a shirt on!) and probably more.
Yes, but synching a basically non-volitional function that is pretty
rapid sounds difficult.

Jon, i am far from worlds greatest vocalist and i can control my vibrato
in strength and frequency. If i can do it surely many professionals can.

Yes, but the OTHER "Jon" said that two vocalists SYNCHED their vibrato,
and I had doubts about that. I have no idea what that might sound like,
or if I could even detect that when listening to the music. (I have some
ancient ABBA CDs here, so if somebody knows which songs feature this effect,
I might take a listen.) The SYNCHING of two performer's vibrato was
what I was questioning. I can use vibrato, too, but have absolutely NO IDEA
how I would synch that to anything.

I can slow my heart rate too, and have done this at science centers, etc.
to show off for people. Mostly by just relaxing.

Jon

Maybe vibrato could be synchronized by injection-locking, via a small
voice coil actuator on each singer's throat. Might be fun to try.

Or you need some imagination. That's around 35 years at 8 hours a day, so
there's little risk to making the claim and being off by 4:1 or so.

I too am very sceptical of those 50,000+ hour ratings. One can only
presume they do some sort of high temp accelerated test to base the
figure on. Unless its just purely marketing guesswork.

However even if they are optimistic by a factor of 5, that still makes
the LED regardable as a fixture, rather than a replaceable item, in the
average domestic/business installation.

I expect it was all done electronically by clever multitrack recording
in the studio.

Yup, I agree.  It would be trivial to do with a MIDI-verb or similar studio
gear of the time.  I can't imagine anybody could sync their vibrato as
a vocal technique, except possibly by standing next to a pipe organ's
pedal ranks.

You throw away the converter with the lamp,
at least one I have has it buld in.
The lamp will only work for a few thousand hours (LED life).
So makes no sense to make the converter last longer.

Having been (at one time) a passably good violinist (my sister is still
a world-class player) I don't find it at all unlikely. The vibrato is
primarily driven by beta-rhythms, which though not under direct conscious
control, can be and are finely controlled parametrically. I never tried
to synchronize my vibrato with another violinist (who was also trying)
but I have no doubt whatever that even I could have learnt it. All the
more so professionals and for vocalists, for whom this control is even
more central to their skills.

An assembly utilizing such a connector and keying device would only
need to have one diagram on its documentation. Each product using a
similar connector would have to have a different configuration. This
keeps you from plugging any given device into the wrong fan tray on the
aircraft.

So, in creating his drawing describing to the production staff as to
how to build the device, the engineer or draftsman would utilize this to
look up the configuration they intend to use on said drawing.

Then, if desired, he could grab a graphic from it and paste it into his
drawing. It is simply a design and production aide.

You have all the engineering aptitude of a slug, Terrell.

To put a finer point on this, The 'diagram' generated would be uniform
each and every time.

As opposed to drafting 216 iterations in a full CAD drawing format.
one uses an 'engine'. This 'engine' which I have created guarantees that
the graphic generated will always have the exact same pixel array size,
and will import into the many drawings the engineering team creates in
exactly the same way each time.

So, instead of making a drawing each time, they pump the index key
number in and VOILA, the graphic and instruction is generated, in crisp
line art, ready for import into an actual engineering drawing.

I know this, because the drawing which inspired me to make it was a
drawing that was a 'redline markup' and had a rough graphic pasted in and
no instruction, which triggered the proto assembler to inquire as to how
to configure the product. I saw the opportunity to fix the redline with
a uniform tool, which the mechanical team can use to insure that the
instruction gets included in the same way in every location (drawing)
where it needs to be.

I may make a project out of generating a mil spec connector selector
which shows the keying and pin locations and donate it to Amphenol and
the other guys making these connector systems.

Right now, everything is through a catalog. If I can open pop it up in
excel with the line art graphic, it will be easily importable to CAD
drawings.

And finally, yes, we most certainly do generate aerospace related (and
approved) documents.

frequency control and feedback is all that's needed for that feat.

it's called a PLL.
