There is not much information, I tried, but here is the chip he is talking about. http://www.lumedynetechnologies.com/Accelerometer.html It has 20 bit accuracy so it must have digital output. The picture shows 24 pins. I think one of the applications could some sort of inertial navigation system. It could be very simple. And we could use it in seismometer sensor. I couldn't find any application information online and I sent the company an e-mail requesting information but no reply yet.

OK, thanks but how about just telling us about the chip so we don't have to listen to the seminar? Who makes it and do they have a part number?
Sorry for being picky but I'm interested in knowing what you are talking about.
Thanks,
Pete

Listen carefully, during the Q&A, an uncontested comment is made that
two midcontinent earthquakes were suspected of being induced.
