Engineering - May 2007

Fairchild has a separate data sheet for each with minor casmetic variations. The pinouts and electrical sprcifications appear to be the same, though. Can I use these parts interchangeably depending on which is cheaper? And if so, why are there two different, yet so similar, part numbers?

we are trying to create a baby bottle warmer for our project ( biomedical engineering field ) , our main goal is to achieve even heating . we thought of using the vibrators so that it will vibrate and shake the liquid in the bottle and generate an even temp throughout the bottle.

can any one tell me if this is a good idea, and if we plan on using the vibrators,what is the speed of the vibrator we should use and what is another way to measure the temperature to assure even heating of the bottle.

I have read on the net that this type of highly available resource would last for 450 years.
Would this not be an environmentally non-destructive method of power production until all other alternatives have had more time for research, discussion and trial to test their safety?
Couldn't the merits of such clean power be advertised to explain methodology, and then subsequent comment and idea feedback.
It would take the heat off rushing into another power souirce that could be politically and environmentally unfvourable., until public is comfortable with a longer life, suitable alternative.

My wife is a qualified Structural Engineer. She has a Masters in Computer Aided Structural engineer and is an expert in ASH/SILO structures. She is also very well versed with AutoCAD and STAAD PRO.

She came to US last year and since the VISA's expired in one day, she did not get a chance to pursue employment oppurtunities. She is now looking for any oppurtunities where her knowledge can be leveraged. She is even ready to do it for free. Basically she wants to get out of house and work.

We are in Altanta. Any body knows any site where structural engineer freelance/oppurtunities are advertised?

Any body has a position in their firm or would use her skills?

There are alot of shows these days that show how things/food are made. Who exactly builds the very specialized machines that make only popsicles or makes only tennis rackets? Is it made by an engineering group that custom makes machines for a client , whatever they plan on making? Or is it more of taking, as I said earlier, an existing popsicle making machine, and then tweak it a bit to fit whatever different kind of frozen confection needs to be made? Cause sometimes you look at a factory machine in operation, like where they make empty soda cans, and it is jammin', making like 100 cans a minute...
