Good presentation -- hybrid apps (e.g. projector) are very interesting ... good potentials for Health applications ... would like to hear more about gas and particle sensors in terms of physics -- data sheets and app notes seem to be around

Proteus BioMed could be a good start ... FOR PREVENTATIVE / Health and Wellness apps as well ...

MEMS Projector very interesting implementation and application

A Hiker's GPS would benefit from the  Altimiter / Barometer (less so, Compass) applications

very good presentation

Iron

what is puncture noise interference?

Hello from San Jose, CA.

HW/Test R&D Engineer.

No Plans to use any this year. 

Thank you Alissa and Alex for another great session.

Iron

Thank you for interesting presentation

Planning to use gyroscope and magnetometer

Thank you Alissa and Alex for another great presentation.  

Iron

Yes, I would definitely be interested in some reference materials for this.  

Iron

The Proteus Biomedical Patient Compliance System is very impressive.  

Iron

Still researching new technology for future uses.  Nothing on the drawing board just yet using MEMS, but within a year there may be.  

Iron

Using the BOSCH pressure sensors for correction of the noise collection systems. Doing LFN (Infrasound) systems. Accurate pressure sensors -- easy to use if you develop a library function which hides the details.

Iron

Thank you Alissa for one more very informative lecture!

Iron

Re. question from Alex - just looked through the MEMS microphones datasheets... quite interesting - digital output directly from the microphone makes things much easier...

Iron

Wonder, do I need to answer questions from Alex?

Iron

Great that we have access to these recordings.

Iron

Missed the class due to travel...

Iron

Good presentations so far.

Iron

...because I'm not HEARING anything. No streaming player popup, I've got the latest Adobe, Win7, IE8, etc...

Platinum

And the frustration mounts. Maybe if I turn off "Protected mode"?

Platinum

Thanks Alissa, This has been a great series so far

adding comments to pad my grade

downloading the slide deck

the others were great i'm sure this one will be also

Okay picking up another missed class

LOOKS LIKE EVERYONE IS GONE. 

 

Iron

Ran: How did you do to get the '@luizcosta' in the beginning of your message?

Iron

@luizcosta - I don't know how to reply to another forum member.  I've wondered and tried to figure out the same thing.  One member recommended a book to me, and I purchased the book that same day.  It was a good recommendation, and I wanted to thank them, but I had no way of reaching them.  I've not seen a posting on the forum since then, so I couldn't thank them during a session.  :.(

Iron

Wow!  This thing is going wacky!  What in the world is going on?

Iron

Thanks Alex.  Also, please give a "Thank You" to Digikey for us.

Iron

@Alissa - A few of us have been asking for your photo so we can have a face to go with the voice.  We've had this feature with all of your predecessors, but nothing this week so far for a photo of you.  Maybe this can help you and us...  Is the photo on this URL a photo of you:

http://www.mem.com.tw/article_content.asp?sn=1106010019&page=2

Since you and we don't read Asian languages, here is the page translation via Google:

It's nice to finally hear AND see you.

Iron

Why is this thing re-posting my previous posts.  This host has so many bugs...

Iron

@JoeFromOzarks - We know all 'bout that.  We be born/reared in W.Va. where the only career choices are make'n shine or move'n on down the line.  That's 'bout all there is.

Iron

ALISSA: if you're still there can you tell me why there is so much limitation with iPhone compass. It seems that most of the time there is EMI blocking the functionality of the app.

Iron

 Incidentely, would you tell me how to reply to someone on the chat by clicking on the nickname?

Iron

I appreciate your emphaty. i think they can/should fix this to only reload the message after the user loags out or times out from the session.

Iron

Thank you Mrs Fitzgerald

Iron

@luizcosta - Sorry to see you're having problems.  It's happened to others as well, including me.  Probably the best recovery you can do is note the approximate time of thread loss and the approximate time of reconnection.  Then come back after the session is over and play back specifically those time windows.

Iron

See ya tomorrow, Alissa.

Iron

Thanks Alissa. Great presentation. See you tomorrow

Iron

Why is this thing re-posting my previous posts.  This host has so many bugs...

Iron

Ok everyone, thanks for listening.  We'll talk tomorrow!

Hey Alissa.  It's good to have you back.

Iron

Thanks Alex.  Also, please give a "Thank You" to Digikey for us.

Iron

Thanks Alissa..

I will listen to the archive!

 

Iron

UPON reloading the page, all the messages are dumped all over again. A true nuissance.

Iron

Thanks Alex and Alissa for todays session, looking forward to tommorrows session.  Signing out.

Iron

BIG PROBLEM WITH THIS TALKRADIO INTERFACE: ONCE YOU LOSE THE THREAD FOR BROWSER FAILURE OR WHATEVER, IT DOESN'T RESUME AT THE POINT ONE LEFT OF.

Iron

Some questions about magnetometers: I'm not too familiar with them, but if you look at the manufacturer's spec sheets, they will usually list the sensing method.  Not all magnetometers are MEMS.

All MEMS mics on the market now are capacitive.

The MEMS mics I have found are capacitive induced. Are there any other types?

Iron

 My question is open to all options at this point. I'm mostly interested in an entry level investment.

Iron

Looks like I am a bit too late..hahah

 

Iron

@luizcosta: to start a garage size MEMS factory to build simple MEMS, if you bought used equipment and had some really great maintenance guys would cost ~ $5M.  That's just to build it.  Then plan on several million a year for power, water, specialty gases and consumables. Building a MEMS factory that could do gyros, etc. would cost about $50M.  But you don't need to build a MEMS garage...many universities allow external companies to rent time in their clean room.  Check out schools in the "NNIN" - a nanofabrication network - like Stanford, Cornell, Georgia Tech, UCSB. Save your money for something else!

I am a little late today, better late than never..Right!

Iron

@dplmark: MEMS are used in some hearing aids.  There are some companies working on MEMS speakers, but the challenge is that the MEMS membrane is very small (<1mm) - it's hard to drive a lot of air (i.e. sound volume) with such a small membrane.  One approach is to create an array of MEMS speakers for close listening range apps.

@luizcosta: To design and have fab'd somewhere else -or- do it all inclusive, in house?

@Alissa  Thanks for another great presentation! 

@Headhunter Thx for the clarification.

Iron

@Daedalus white goods are refrigerators washers,dryers etc.

Iron

ALISSA: What would be the approximate minimum budget to start a "garage size" MEMS factory? Alternatively, an evaluation lab to refine manufacturer's specifications?

Iron

@ebloohm: there are MEMS sensors for measuring pH, conductivity, etc.  I can't recall the manufacturer names, but the Abbott iSTAT blood analysis chip contains MEMS devices that can measure those items.

@Alissa Great, thanks for the info!

Iron

@Lawson: DLPs go into TVS as well as projectors. TI is the #1 MEMS supplier by $$ because the DLP is an expensive chip, >$100 whereas most other consumer MEMS devices cost <$3. I can't recall if TI makes any MEMS other than DLP.

ALISSA:  iPhones to me became 95+% impressive. However, I personally struggle using the iPhone compass. It seem there is a lot of sensitivity with radio/cell tower EMI. Can you elaborate on that problem and what solutions are out there?

Iron

So would you recommend using acceleromters with a pressure sensor to corelate altitude change?

Inside a building the pressure will vary from space to space epending on HVAC operation, No?

Iron

@kwanchat: I would say the Auto industry. Automobiles are much safer today thanks to MEMS - airbags have saved thousands of lives.

@Alissa Does TI make any MEMS other than DLP?  The slide you showed the first day had TI as the #1 MEMS supplier.  Do the DLP MEMS chips go in the DLP TVs as well as projectors?  Does each device need a lot of MEMS?  Wondering why TI has the highest MEMS revenue.

Iron

@Alissa From slide #3 what are PND and White goods?

Iron

MEMS mics are very low cost, < $0.30 in volume

Speaking of frosty beers, those of you with iPhones might want to check out the "iBeer" app.  I'd have to say it's the most frivolous use of MEMS technology I've seen yet!

Which industry that you know of has made most advances with MEMS devices?

Iron

Are there MEMS sensors for measuring water parameters such as pH, conductivity,dissolved oxygen etc...

Iron

Thanks for a great presentation!

Iron

Thank You DigiKey and Dr Fitzgerald

Iron

Enjoyed...Thanks A & A.

Iron

Question- still no reply on MEMS electrostatic susceptibility-internal and external

Iron

@mrgilbert: there are some MEMS development boards out there - can't recall too many names at the moment, but I believe Colibrys offers some.  Crossbow used to, but not sure they still do.  STMicro has their iNEMO platform as well - I'll talk about that one tomorrow.

Tres Bien !

Merci beaucoup Mssrs Alissa, Alex & Digikey.

Iron
