We're working from the same source. I don't have a 4 million volume library,
but my brother owns the book. I was thumbing through it over Christmas.
Now that you mention it, I do remember that bit about the 16"/L56. I made 
my statement based on a picture in the same book of the 18"/L48 on display
at Dahlgren. Granted, it looked old, but I got the impression that it was
a 1950's vintage picture. Could I be hallucinating again? Another poster
mentioned that three of these guns were built. Perhaps only one was
converted? I'd check myself, but it's 400 miles to my brother's house,
and he's not even home.
   Now for some REAL speculation: Were these guns built for the South 
Dakota I (BB-49) class? Several sources, including S. Breyer, mention that
the first specification for these ships called for an 80,000 ton ship,
with fifteen 18" guns and a speed of 35 knots! Apparently, this idea was
abandoned very early, but could these have been the guns they had in mind?

Again, I see another Wiley Coyote scenario.  As he rises to see over a
cliff, he hears a "Meep meep" in his headset signifying a radar lock and
launch.  He hits the ejection button, only to get a rocket assisted pug job
on the opposing rock face.  And as his helicopter careens wildly away, it
evades the incoming missile, which since it was coming up from behind
anyways, proceeds to blow him further into the rock face. 8-)

Since almost any ejection system depends on a delta vector away from the
doomed craft to provide the pilot safe seperation.  Given that a helicopter
can have a 0 delta, and would have to manufacture one for the pilot, and by
the nature of a helicopter only vectors to the right or left have any
reasonable guarantee of not running into something, I think leaving the
ejection system off and putting on more armor is the most prudent course.

    The Brits make a device that shows what direction a bullet came from.  It

though I'm not really sure on that point.  Anyways, you have a readout that
shows what direction the bullet came from.  I'll have to look up the rest of

An explosive charge to blow off the rotors at the beginning of the ejection
sequence is more likely.

I'd hate to be the first pilot to actually *try* it, though.  What if the
rotor stayed around the neighborhood just a bit too long, say if the whole
rotor assembly came off in one piece, instead of scattering the blades.

The "blowing off parts of your previously-perfectly-good airplane first"
approach was tried with at least one pusher-prop-driven fighter in the
1940's.  (Curtiss XP-55 Ascender. Don't know if it was actually *tested*,
though.)

>A downward ejection?  That sounds like something out of a Road-Runner cartoon.  

Or from early versions of the F-104.  (At low level, first you roll inverted,
*then* you punch out.  Sure.)

Well, apparently, a few pilots actually *did* manage the trick, but Lockheed
went back to an upward escape later on.

From Fengxi Zhou <fengxi@prancer.eche.ualberta.ca>

While talking about self-propelled anti-air guns, how come nobody mentioned
italian OTOMATIC 76/62 gun? It has the range, lethality and accuracy. With 
the help of the new CCS (course corrected shell, a crude form of guided shell
but good for shooting down sea skimming missiles, developed by OTO Melara
and British Aerospace, use a bunch of small rockets instead of moving fins),
it should do quite well against helos and low flying a/c. It can also fire
fin stabilized sabot so it can kill pretty much anything on the ground 
except the frontal armour of MBTs. Originally, it is mounted on the chasis
of Palmaria (Italian SP 155mm gun) but it should be easily adopted by other
MBTs or SP guns.

Now, some data for otomatic:
road speed:     60 km/h
range:          500 km
rate of fire:   120 round/min
Gun:            OTO Melara 76mm, 62 caliber

Compare 76/62 gun with other small/medium caliber guns, here are some data:

				  Phalanx     Goalkeeper    Bofors twin 40   76/62
caliber           20mm        30mm          40mm           76mm
type              gatlin      gatlin        twin barrel    single barrel
rate of fire      3000        4200          900            120
(round/min)
muzzle velocity   1100        1020          1000           900
(m/sec)
effective range   1000        1500          3000           5500
(m)
distribution      1.1         1.2           1.0            0.5
(mil)

So the 76/62 does not fire as rapidly but is much more accurate and lethal.
Phalanx basically deploys a "steel curtain" to block the path of the incoming
missile or a/c and more or less count on multiple hits to destroy the target
or set off the warhead. But a single hit by a 76mm shell can pretty much 
eliminate any chance the thing can still fly in one piece. A longer range
also brings in the benefit of a second chance in case the first salvo didn't
get the bandit which is not an option for smaller caliber guns.

Maybe someone is still not convinced higher accuracy and longer range can
make up for the lower rate of fire. Italian navy's newest destroyers Animoso
and Ardimentoso are doing away with their Phalanx equivalent Dardo (twin
30mm Breda guns) and using 76/62 guns only for anti-missile mission. Well,
if it can shoot a sea skimming missile down, it sure can shoot a helo or
a low flying CAS a/c down.

I recently ordered a Powerglove directly from Mattel (1-800-635-5511).
I called them on a lark and was surprised when they told me they were
selling them.  The cost was US$30.00 (including shipping).  According
to what I was told, they have about 80 left.

There are some caveats, however.  First, they required payment in
advance (by _check_; no credit card accepted).  Second, from what I
was told it sounds as if the gloves that remain are reconditioned ones
that were repaired after being sent back by the original purchasers.
Third, the glove they sent me came without instructions; if you order
from them, it would probably be a good idea to explicitly ask that
they send instructions along with the glove.  Fourth, the glove I
received from them didn't work, though they're replacing it for free
and paid for the return postage on the broken one I sent back (maybe
you can get _that_ one :-).  And fifth (don't worry, this is the last
one), I received conflicting information from different operators at
the 800 number concerning whether Mattel is still selling the gloves
to the general public.  In four calls, twice I was told that Mattel is
selling the gloves and twice I was told they aren't.  The last time I
spoke with them, when I was making arrangements to have the defective
glove replaced, I had to press a bit to get the operator to say that
they were still selling the gloves.

If you decide to try out this Powerglove source, others reading
sci.v-w might like to hear about your experience with them.

Regards,
Bryan

That's EXACTLY the problem: since the DataGlove I used has just one sensor
for the metacarpophalangeal joint of the thumb, I cannot map the REAL thumb
movements into the ones of the model; I must LOCK the thumb, taking off ALL
its degrees of freedom, except the one measured by the only sensor.
So I must carefully choose on which axis make the thumb move.

Clearer?

FYI, only one reply (thanks John! Great idea a moving axis...) and one pointer

Yeah ... I played with my fingers and it works (makes sense because
there's only one `string' being pulled).

Uh oh ... problem is when you actually grab something real: you go
back to three degrees of freedom. Example: put your hand flat on a
table with the last joint of each finger hanging off the end. You can
then wiggle the last joint without wiggle the others to any
significant extent.

I suppose the importance of this depends on whether you *want* to grab
real objects in your application (or only virtual ones).

I'm selling my powerglove and my sega glasses, they're both
about 6-7 months old and weren't much used anyway. If someone's
buying everything together, I can join (for free) the small
interface circuit that I built for both devices. Don't expect
a hi-tech surface-mounted pc-board, though.

Price for each device is 30$ and for 50$ you get everything.

Please e-mail me at claudio@flamingo.stanford.edu if interested.
