I assume you are thinking of a patent. Be careful as there are crooked patent agencies out there. Start with the us government patent office. Do a web rearch for patent office and you will get a lot of (488529) references. wzkb <They are just Jealous that the Voices don't talk to Them>

Thanks jbarto, I'll check them out. wzkb <They are just Jealous that the Voices don't talk to Them>

Seek advise on an NC machine to take 3-D .STL files and produce an object whose visible surface matches that of the object. Desired output max size: H=45 cm, L=30 cm, W=30 cm (smaller could be OK to begin). Should be capable of thin (i.e. around 1-2 mm). Example: coffee cup from wood or a cat's...

Thanks for the tip. I will still need, on occasion, to use real wood. wzkb <They are just Jealous that the Voices don't talk to Them>

Seek advise on an NC machine to take 3-D CAD output and produce an object whose visible surface matches that of the CAD object. Desired output max size: h = 45 cm, w = 30 cm (smaller could be OK to begin). Should be capable of thin (i.e. around 1-2 mm). Example: coffee cup made from wood As an...

The best allin one place source is &quot;Transmission Systems for Communications&quot; by Bell Telephone Labs. I have the fifth edition (1982) and have used it extensively. Try to fine it in the library as it's out of print. wzkb <They are just Jealous that the Voices don't talk to Them>

On one of the eng-tips forums i found the following link: http://www.fortran.com/imagine1/ <They are just Jealous that the Voices don't talk to Them>

Signal Transformer I think is the name of one good one. wzkbrown &lt;They are just Jealous that the Voices don't talk to Them&gt;

What type of devices need to be designed? &lt;They are just Jealous that the Voices don't talk to Them&gt;

Unless there is something on the MathSoft site I cannot help much. I have a copy of some work - &quot;Vortex Method Simulation of Turbulent Flow&quot;&nbsp;&nbsp;by Peter S. Bernard that I could send you if you will contact me directly.&nbsp;&nbsp;I found it on the net.<br><br>Summary:This...

I suggest a lot reading in the IEEE publications on Speech Processing.&nbsp;&nbsp;Read Rabiner.&nbsp;&nbsp;Get the free Microsoft Development stuff.&nbsp;&nbsp;Search the internet newsgroups.<br>k

Check the Rockwell(Connexant) Site as well as Cermetek.<br>Exar and Motorola had some good tutorials in older data books for low speeds.<br>

I found SEMTEC supplies chips in many configurations.<br>k

Check the Analog Devices Site (<A HREF="http://www.analog.com" TARGET="_new">www.analog.com</A>)for ICs to do the job as well as application circuits using general purpose Op-Amps

Use capacitor cross-coupled transistors, the CD4528 (or123, 221, 423) or build one from schmidt triggers (HC14s).<br><br>Look im most circuit design texts for a detailed amalysis of the transistor ckt.<br><br>You can also look at the LM555 timer chip.&nbsp;&nbsp;National had a great app. book on...

The 20KV requirement is the killer.&nbsp;&nbsp;If this is the minimum, you are out of luck.&nbsp;&nbsp;If it is just what happens to be currently designed in thing, look at how it must function.&nbsp;&nbsp;There are devices that can operate into the 1-3 KV range. (cost is another factor hi KV =...

1] there is no solder under the lead,&nbsp;&nbsp;The only thing to connect is the pressure of the lead on the pad.&nbsp;&nbsp;The electrical connection is through the solder fillet. The only thing holding the IC to the board is the solder fillet.<br>2] There is no way to inspect the solder joint...

I can think of at lease 4 ways to do this.&nbsp;&nbsp;We first need to look at your requirements:<br>How much should the circuit cost? (nothing and as little as possible&nbsp;&nbsp;are not options)<br>How much have you to spend on doing the design?<br>Do you want a Hardware solution? -...

Am a visitor today.&nbsp;&nbsp;I am an EE (analog and digital, no RF) currently working in sewer/wastewater instrumentation (how did I get here?).<br><br>How would I send a schematic or pdf file in a response?<br><br>I'll keep an eye here for a while.<br>k

Look at Garage Door Opener technology.&nbsp;&nbsp;Known and available thru Digi-Key.<br>k
