Abstract for the next EIT conference in Germany ICEBI2013

[Pascal Olivier Gaggero]

Dear OEIT followers,

The task force "OEIT" worked intensively in the past month to gather ideas to move towards a first version of OEIT.

We would like to share with you in the coming days and weeks more and more information about our thoughts on the subject. We are looking forward for your important feedback.

As we should start somewhere and because we decided to submit an abstract for the next EIT conference in Germany, we would like to open the draft to the community for discussion.

We uploaded the draft in a pdf, odt and google doc file:

https://docs.google.com/file/d/0B8Yc4c86UHemUFZmM3lXNjloYzA/edit

https://docs.google.com/document/d/1ljnnBF4_XPk-Y9yWdAzkS4DcRi0trqKNgETdYWJaGzo/edit

https://docs.google.com/file/d/0B8Yc4c86UHemel9WVUcwSEQ5aFk/edit

best regards,

Pascal, Bartek, Hervé and Andy

P.S. The deadline for the draft submission is 31st of January.

Hi Pascal, I agree this is an important project and should lead to some interesting discussion at the conference.  My thoughts are: while I agree storing volts is important, do you propose to have magnitude/phase or real/imaginary as the standard format - due to the issues with phase unwrapping? and it would be good to include contact impedance, calibration data and reciprocity to encourage acquisition of these as an indicator of data quality.

Cheers, Alistair.

Dear Alistair,

Thank you very much for your support for the OEIT project, and I am looking forward to the discussion at the upcoming conference.

Here are some comments regarding your question:

- The task force OEIT debated the subject of storing volt versus storing the raw value and an extensive gain model.

   -> after those discussion majority was in favor of the later, thus allowing more user control on the data processing. But I must say that their is nothing in the format preventing someone from storing double value with gain 1...

- phase wrapping: If you have a mean to measure it, their is nothing in the format that prevents you to store phase larger than 2 pi.

- Contact impedance: They are stored has every other measurement.

- What kind of calibration data are you talking about, could you give examples?

- Isn't reciprocity calculated from the data? What is the point of storing the value separately?

What do you think?

see you,

Pascal

P.S. this week I am gone post some more examples of configuration files to illustrate my comments
