Thanks jon, very good presentation

Iron

Very good session, lots of overviews.

I had to run to a meeting, but finished this when I came back.

Iron

Can't wait for tomorrow's session!

Iron

Thanks Jon.  And don't forget to buy milk on your way back home :-)

Iron

Have a great evening.

 

 

Iron

good idea. -- Video processing with edge enhancement and thje ability to discern thisng will be a neat technology. It is already being used for gestures and facial recognition.

 

"f the fridge needs to know what's inside, it will just use a camera to send pictures to the nearest computer, which runs image recognition to see that the soy milk is finished and need to buy more.

That is Internet of Things because the devices actually TALK to EACH OTHER..."

 

Iron

tomorrow, it's my OFF...i will go through the archived to learn more...

good evening & goodnight to all...

sir jon, thank you so much...

anyway, thanks to all colleagues and classmates...

i think i will go through the archived for more topics and finishing at all...

If the fridge needs to know what's inside, it will just use a camera to send pictures to the nearest computer, which runs image recognition to see that the soy milk is finished and need to buy more.

That is Internet of Things because the devices actually TALK to EACH OTHER...

 

Iron

that's fine jongabay...i appreciates all of your write-up here...reading at all...

sure, tomorrow will be the last day

Tomorrow will be cloud services --- Jon

 

Iron

I don't think the refrigerator would lock you out. The wife might...

Iron

Thanks everyone for participating. Please join Jon again, same time tomorrow.

A fridge could know when something is low if a weight based sensor is in place or if a level sensor was in a container or pitcher. It would mean that a higher level of standardization of packaging and specific locations in the fridge for different things.

It may not be feasible, but it is an example as to what can be done.

Years ago, I worked with a company to develop weight based bottle sensors that would stop bar tenders from giving out too many free drinks to boost their tips. Every bottle has a specifie location and you are correct, a data base was created and maintained.

 

 

 

Iron

I don't think that refrigerator is a right example, because that will create problem, right?

Yes, older 1G and 2G technologies will not be supported forever. It costs to support older infrastructures if there is now payback. New towers won't support it soon.

 

Iron

I think a refrigerator would be analogous to Quicken. I could get get these beautiful charts and graphs but I had to spend hours inputting data. How is the refrigerator going to know I need milk unless I tell it everytime I buy some and consume some. We're a long ways away from having a standardized RFID tag on every product and this would mean a whole new level of complexity involving memory and access to databases.

 

Iron

Note -- put manual overrides into your automation technology. Otherwise, when things go wrong, they can go very wrong.

 

 

Iron

'So the street people wearing tin-foil hats are really smarter than the rest of us?'

 

Actually, it was found that fold can actually increase the amount of RF eneergy the body absorbs.

 
 
 
Iron

Embedded RFID tags are 99% passive, and respond only to an active source using the active source signal as the power source.  THe tags are removable from garments and items, it is typically for inventory. --

Tags can also be active with dual port functionality and up to 16 Kbit non volatile storage that can be read or written to remotely.

 

Iron

Good general info on the wireless technologies.

Thank you all.

Iron

That's right - old phones were 5 watts. theu are now around 1/2 a watt. Dynamic energy modes based on Recieved Signal Strenght are helping to reduce power.

 

 

Iron

Jon, about Bluetooth messages from my fridge.  Now you have me scared.  So, if I miss the message and forget to buy milk, my refrigerator could decide to lock me out! 

Iron

Good Find --

 

May 8th, 2013 -- SAN FRANCISCO (Reuters) - San Francisco city leaders, after losing a key round in court against the cell phone industry, have agreed to revoke an ordinance that would have been the first in the United States to require retailers to warn consumers about potentially dangerous radiation levels.

the 9th U.S. Circuit Court of Appeals ruling had left San Francisco in the position of having to prove that scientists concurred about the hazards of cell phones and that the FCC no longer believes they are safe.

Iron

Isn't IOHomecontrol used in HAN by smart appliance manufacturers? --

 

It may be. i am unfamiliar with this one. I have seen appliance manufacturers advertise Bluetooth connectivity. I think someone makes a bluetooth refrigerator.

At first, you may think, why does my refirgerator need bluetooth?

Here is where intelligence distributed around the facility and world can make a difference.

 

If your cell phone reports your position with GPS, your haous may know that yuou will be passing a convenience market. Your refigerator can say "I need milk" and text you to stop at the convenience market to pick some up.

@UBM -- content directors, curriculum advisors, course responsible individuals --

After two dozen digi-key CEC classes archived online, the material does not seem to flow well in a programmatic sense.  Early coverage of general concepts of networks, topologies, tradeoffs and such as one simple example, would provide for much greater depth of content in later classes.  If development classes are planned for Fall 2013, it would be nice to generate a list of pre-requisite classes and review content to minimize replication / maximize focus, content depth.

Thanks to UBM, Digi-Key, the presenter-lecturers and the excellent interaction of the attendees for these very useful and insightful classes -- and for archiving them.

Sitting around a campfire discussing this technolgy would be great. I know there are a lot of caviats and issues, and it is hard to try and cover this in a 30 minute presentation in 5 days.

 

Iron

now, i do understand what's all about...very interesting...i have learned something new with the lecture

There really isn't compatibility among different wireless technologies. A WiFi node will not be able to read a bluetooth node. While they share the same bands, they have different schemes. One uses direct sequence spread spectrum technology, the other used frequency hopping. A gateway box is needed.

Iron

Thanks everyone for attending. Jon will answer all your questions now.

Blogger

thansk for the info 

Iron

Jon & Rob, thanks for the presentation.

Iron

Thanks Jon for the lecture.

Iron

Thanks...this lecture was very ineteresting.

 

Iron

Jon - nice presentation ... lots of good information covered.  Would be nice to sit around for a weekend at a camp in the woods going through these concepts ...

Thanks Jon & Rob.

Iron

excellent lecture once again sir jon

Thanks a lot, great presentation

Iron

Thank you.  Extremely interesting.

Iron

Thank you Jon! Was a fun lecture...

yap, same thing with me...i don't know why...

yes, someone needs to mute their mike

 

Iron

I can hear someone beside Jon and Rob periodically...

i don't remember the power .. maybe 5w but battery didn't last long.

Iron

We're now on slide 15

Blogger

The further away from the tower, the more power output from the phone...

 

Iron

Biggest Con of Wifi for small embedded devices is FCC certification!

Iron

Something like 5 to 10mW?

 

Iron

no idea rob, but i am looking at it...still listening with jon

The 1G & 2G networks clog the bandwidth for the cell phone carriers.  They are dropping support.

Iron

Now the cell phones put out low power but 4G drains the battery rather quickly where available.

Iron

AT&T no longer certifies new 2G devices.  Period.

Iron

Quewstion from Jon:

Does anyone know how much power early generation cell phones used to put out and how mushc they put out know?

Blogger

2G up to 33dBm

3G up to 23 dBm

 

3ft line of shight range?...

Iron

We're now on slide 14

Blogger

AT&T and Verizon both have announced they are getting rid of 2G networks in the next several years.

 

Embedded RFID tags are 99% passive, and respond only to an active source using the active source signal as the power source.  THe tags are removable from garments and items, it is typically for inventory. 

 

Jon's question:

Does anyone know which senator warned the cell phone industry not to  withohold safety information?

Blogger

So the street people wearing tin-foil hats are really smarter than the rest of us?

Iron

RFID is great for bulk inventory taking and efficiently managing logistics.

Jon's question:

Does anyone know what the present 12 DBm RFID line of site reading range is?

ok, i will just wait our dearly sir jon for his interesting lecture...

Not from New Mexico but wish I was there rather than here.

Iron

thanks again gwp2...but, amazing noh! causing cancer...

ahhh, ok, i found it. RF means a radio frequency that is energy harvesting and wireless power

Hello from Albuquerque.  Beside our host, Rob Spiegel, anyone else from New Mexico here?

Iron

my dear colleague, what does RF means in our material? i am looking at it...

Total electrical energy consumption in 2011 was 4,138 Billion kWh (B kWh).

126.1 Million residential customers used 1,446 B kWh - 34.4% of USA's 2011 load.

17.7 Million commercial customers used 1,328 B kWh - 32.1%.

728K Industrial customers used 991 B kWh - 23.9% and

92 Transportation customers used 8 B kWh-0.2%.

388 B kWh or 9.4% were system usage (133 B kWh) and system loses and unaccounted loads (262 B kWh).

Average residential cost/kWh was $.1172 with a monthly usage of about 940 kWh for a cost of $110.17/month. Per capita consumption from the electrical grid in 2011 was 13,187 kWh and is essentially the same as a decade ago-2001.

 

Based upon data mined from US DOE Energy Information Administration/Electric Power Annual 2011 files.  Data was obtained from the most recent DOE Energy Information Agency (EIA) files.

i am just reading through the materials prior to our host lecture
