Thank you Randy and Chuck, Very interesting presentation

No for sensor fusion project

Glad the phone didnt die out

I'm not planning on any sensor fusion in the near future

Looks like a lot of complex material for this lecture

Cold today in Albany NY

Okay almost done catching up with the last few weeks

@host - not planning to do the sensor fusion in the nearest future...

Iron

@host - sensor fusion project in the next 6 mos - NO

Iron

Great to have access to the recorded sessions

Iron

Missed the live lecture

Iron

Any work would be with motion and viration sensing -- perhaps linked to audio.

For an explanayion of how to use C to develop Quaternions see here:

http://www.cprogramming.com/tutorial/3d/quaternions.html

e.g.

A quaternion represents two things.  It has an x, y, and z component, which represents the axis about which a rotation will occur.  It also has a w component, which represents the amount of rotation which will occur about this axis.  In short, a vector, and a float.  With these four numbers, it is possible to build a matrix which will represent all the rotations perfectly, with no chance of gimbal lock.  (I actually managed to encounter gimbal lock with quaternions when I was first coding them, but it was because I did something incorrectly.  I'll cover that later).  So far, quaternions should seem a lot like the axis angle representation.  However, there are some large differences, which start....now.

Yes to sensor fusion -- but very simple.

Iron

Just catching up

Thanks Randy and Chuck. A really interesting week of classes. You've opened some new ways of problem solving and added a few more ideas for my tool box.

Iron

no sensor fusion project in near term, 6 months.

Iron

Thanks Randy; Great topic

Iron

I'm not involved in sensor fusion

Iron

Great topic and good info

That's going to do it for today.

Thanks to today's listeners and those who attended any or all of the other sensor sessions.

What were the objective improvements ? ie. probability of detection vs false alarm rate ?

For some systems, such as the autonomous vehicle, sensor fusion is the key to the end result. Without it, the reaction is not what you want. Other aplications may provide an improvement in key sensor output and higher probablity of detection fewer false triggers. You do not want to do sensor fusion just for the sake of saying you used it in a product because there is a cost (development time for software and additional hardware) associated with sensor fusion.

thanks Randy. great week... learned a lot.

Thank you Randy and Chuck.

Iron

Thanks for all the lectures Randy

Iron

Indeed these webinars were great resources to us. I wonder for how long the lectures will be archived.

Thanks, Randy and Chuck

Iron

... afternoon. Thanks

Iron

Thanks for the lectures.  Very informative.  

Iron

Thank You Very Much Randy

Iron

Thank you very much...

Iron

Thank you Randy for a week of great information.

Iron

Randy, thank you for the lecture series. Thank you Chuck hosting and Digikey for sponsoring

Iron

Many thanks Randy, Chuck; a good week.

Iron

Thank you, very interesting

Iron

Thanks, Randy! Great week of lectures.

Look at this:

http://www.all-electronics.de/texte/anzeigen/47607/Das-Radar-fuer-die-Westentasche

It's a complete Radar sending at 122GHz in one Chip smaller than one Euro-Cent.

Iron

FYI, the ADIS1640 is over $2000

@Chuck - variety of different sensor types.

Iron

accelerometer, gyro, and visual

Iron

video camera and a 6DOF IMU 

Need to fuze phone battery with external energy harvesting.

Iron

Have not had any problems with audio previously.  Having lots of problems today with audio cutting out and requiring a page refresh to start it again.  (IE9)

Iron

What were the objective improvements ? ie. probability of detection vs false alarm rate  ?

Iron

youre good, auto_tink.

Blogger

Sensor project: motion (acceleration, velocity), direction fusion - estimate of location when GPS unavailable.

Iron

Ok now they are.

Yes reliability checking for me too.

Iron

Hi everyone from California. Little late. Not sure it my posts are going through.

Iron

reliability checking

Iron

Robotics application

Iron

Currently doing industrial sensors.

Some days I feel a bit fuzzy about logic

Iron

Yes, sensor integrate GPS and IMU

 

Iron

Possibly personal, at work no.

Iron

Sensor fusion projet in next 6 months: No

Iron

Good afternoon Randy.

Iron

Hello from Mich. again again

Iron

Hello from Midland Tx

Iron

Nobody has more fun at a ballgame than Cubs & Cardinals fans!   :)

Hello from Albuquerque.

Iron

A lot of usefull information this week.

Hello from Mesquite NV.
Iron

Good afternoon folks.

Iron

Hi from Lübeck, Germany.

Iron

Hi from rainy chilly Boston

Iron

hello from sunny miami...

Hello from Milwaukee

Iron

To the What Makes a Smart Sensor Smart question yesterday,

the SCADA answer is Connectivity

Iron

looking forward to hearing about "Sensor Fusion Confusion".

Good afternoon from Chicago, home of the Cubs and White Sox, neither of which are in the playoffs.

Good Morning / Afternoon from San Jose, CA.

It's 54°F Cloudy and High of 64°F.

Iron

Howdy folk!   GO STL CARDINALS!   :)

Looking forward to today's session ... 

These have been very informative sessions.  Appreiciate the opportunity to listen and view the presentations.  Thanks

Iron

...morning from cenral Alaska

Iron

Good morning from the dreary, wet south.
