I read in sci.electronics.design that Jim Thompson

about 'US Patent Office Site - Image Viewer Problem', on Thu,
24 Feb 2005:

I visited the USPTO website today (using Mozilla Firefox) and got a
message that Quicktime Plug-In installation was required.

Quicktime is already installed on my machine, but I clicked the install-
plug-in box anyway. But it won't install, getting a "manual install"
message. That doesn't work either.

Fired up IE, it just shows the "no image" symbol.

Ideas? Or alternative plug-ins?

If you do find a way to get into the site, patent it. (;-)

I was about to say, before you so rudely cut me off, that AlternaTiff
works for the USPTO site.

Irfanview is great for viewing saved tiff files, too. I just wish it
would view Autocad files.

The remote for my Panasonic DVD-S27 is the first I've seen that
won't
bounce off walls or even mirrors to control the unit. I'd like it
to do
that because it's set up behind the viewing couch next to a
projector
for a short cable run. The batteries are brand new. Could its
particular type of infrared LED be the problem, and could it be
changed
with no ill effects? I'd prefer not to attach an infrared booster
unless I have no other choice. Thanks.

What are the advertised range and maximum angle of the remote?
Perhaps
your reflected path is just too long or your mirror is not angled
properly.

I've tried all possible angles, even putting a mirror just a foot away
with the total distance being about two feet. I only need to reflect
off a projector screen (and/or wall) 12-15 feet in front of the sitting
position and that's effortless for my other remotes.

Hi,

In response to "Do you have a dimmer circuit with MOSFET to suggest?"
Tomi responded with "CMOS gate implement
s reverse phase control - this circuit implements a
"reverse" phase control, using only a single CMOS 4001 quad NOR gate,
conduction begins at the zero crossing of the ac sine wave and the
turn-off timing is adjusted based on dimmer setting
http://www.e-insite.net/ednmag/archives/1998/052198/11DI.htm#CMOS%20gate%20implements"

I'm interested! I can get to the article but the circuit diagram (figure
1) is supposedly stored in a .PDF file...that will not come up. Has
anybody got another source for this circuit? Or is it just me who can't
get to the .PDF file?

Downloading the PDF did not work for me either :-(
I has link to this ciruit, and posted the address whe I saw that
circuit page to work... Did not test the download of all parts..

EDN magazine seems to change their archive every now and them...
Result beuing that links tend to break down every now and them.
It is now not the particular link on the t circuit, every PDF
link on that page seems to be broken because of their new system..
One idea would be to contact the webmaster of that site
to report of the problem and ask to correct it.

I might have that circuit printed on paper somewhere, maybe
even electronic copy...

Perhaps the receiver PD is a narrow angle? Did you try other remotes?

I figured out a way!

I was focusing only on the motor controller IC. I then shifted focus
to other parts of the circuit. I thought that if I could trick the
circuit into thinking that there's a read/write head, then maybe it
would not shut down.

I made a connection from one of the pins leading ot the read heads and
connected it to a digital line that gives a lot of alternating ones
and zeros.

It worked. The motor starts up and remains running smoothly. So I
saved myself buying or building a brushless DC motor controller.

its really nice to hear.can u explain me in detail.iam trying to fix it
since 1 month.imean trying to run HDD motor with out stopping.but no
use.
my HDD is samsung 20GB model.if u any other circuit which can drive HDD
spindle motor
ple help me
thanks

I am trying to create a driver circuit to allow recording and playback of
sound to a 3.5 inch floppy disk using a standard floppy disk drive...

Does any body know anything about what actually happens when you record or
write/read to a disk??
I've read a lot about flux reversals and stuff like that but I was
convinced music/sound could still be recorded in my way mentioned above.

Given the type of head used your best bet is to use either a digital or
an FM version of your audio signal to record.

I suppose FM will be easier.

An HD floppy drive is 300 RPM and 100 kbits per track. A bit is a flux
reversal with MFM so your carrier should be somewhere between 250 and
500 KHz.

Just hope that the drive doesn't do any 'signal alignment' for you...

jesrandall · Feb 26, 2005

thanks thomas, your suggestions are very helpful, i hope it works. Are
there any sites or books that I can learn more about floppy drive details
such as the bits/track you posted.

You suggested I use a digital signal, but I actually already am... I
havn't tried using analogue audio yet...I'm just trying to record digital
tones produced by 555 timer, right now. The FM idea sounds good... but why
can't I use the low frequency (2000-3000hz) audio sound im using write
now... is there a physical attribute with the floppy drive heads that
prevents this.... I don't mind using FM but I'd like to understand why I
have to. Also, the strange effect I got... when I held the write input low
but still got a tone on the read pin. I know according to MFM format all
zeros are mixed with a clocking signal (explainging the tone I got), but
does the drive automatically convert incoming signals into MFM format???
Thanks a lot for helping me...

-Jesrandall

jesrandall · Feb 27, 2005

thanks everyone for your suggestions. I will try encoding the sound through
fm with a carrier frequency of 40-70khz... hopefully it works. I havn't
picked up any "noticable" cross talk between the tracks. Since I have been
able to record "pulses" and hear them on one track, but hear nothing on
the adjacent track... hopefully I won't have any problems with
interference.

ArdentGuy · Feb 28, 2005

Tom,

Yep....every single link on the page seems to be busted. I sent an e-mail
to the webmaster right after I posted here four days ago. I haven't
gotten a response yet....but then again, it's Monday morning!

If you can reproduce the circuit, that would be a great help!

Thanks,

John

Actually there is little in Toronto worth the cost of a nuclear
warhead. Still, we already know that these ragheaded desert rats can't
comprehend simply logic. After all, the dumb bastards just blew up 120
or so of their brethren in Bagdad yesterday, so go figure.

My simple solution would be to put out a little bait for these
terrorist, and once they have congregated in mass, nuke the whole
place. We missed our golden opportunity to do this with Fallujah, but
other opportunities will likely surface.

With what army will PM Martin be enforcing such a ludicrous statement?

So every political statement that our prime minister makes has to be
enforced with a point of a gun? "Yeah, lets shoot a round over their bow to
see if they are friendly"

Seems Canada's principal worry should be whether the Koreans are
sufficiently competent to CLEAR Canadian airspace!

Korea is not your problem. It is you WANT for an enemy that is the problem.

Bye, bye, Toronto ;-)

Since a "shot down" missile would probably land on Canada those Canucks
better get started on an "anti-anti-missile-missile" system.

Yeah, and it facinates me when Hawks talk about "Missle Defense":

the warhead was left intact to impact near the original target.
