Do you know how to save this to a file?

Thank you for posting the Movie Wesley!
Chet
To save video I use
RealPlayer Plus
but you can also use another very good set of programs:
Your Software Status
Replay Media Catcher 4.1.1
Update to version 4.1.6
Replay Video Capture 4.2
Replay Music 3.98
Replay AV 8.82
Replay Converter 4.07
Replay Media Splitter 1.9.1012
Video Padlock 1.14
Replay Telecorder 1.2.0.4
I think it is even better Than RealPlayer that presses you to upgrade
cosing problems after any new upgrade they make.
(Than you see that your ability to upload Youtube is no longer
till you load upgrade that cost you money)

Very interesting PDF
explaining
1.Frequency response of ferroelectric capacitors
2.why ferromaterial with permanent dipoles can NOT be used in microwaves
3. permitivities are at low KHz
4.Permanent dipole reorientation can flow only at MHZ-GHz
5. ferroelectric capacitors can store more electric charge due to dielectric polarization.
6. explanation how elastic energy(Vclas) and dipole interaction (Vdip) combine equals total energyV(tot)
CAN ANYONE TELL ME why!!!!

Abstract
The present invention facilitates evaluation of ferroelectric memory devices. A ferroelectric memory device is fabricated that comprises memory cells comprising
ferroelectric capacitors (802). A short delay polarization value is obtained (804) by writing a data value, performing a short delay, and reading the data value. A long delay polarization value is obtained (806) by again writing the data value, performing a long delay, and again reading the data value. The short delay and long delay polarization values are compared (808) to obtain a data retention lifetime for the ferroelectric memory device. The obtained data retention lifetime is compared with acceptable values (810) and, if deemed unacceptable, avoids unnecessary performance of thermal bake data retention lifetime testing.

Giant effective pyroelectric coefficients from graded ferroelectric devices
Jin, F.; Auner, G. W.; Naik, R.; Schubring, N. W.; Mantese, J. V.; Catalan, A. B.; Micheli, A. L.
Applied Physics Letters, Volume 73, Issue 19, id. 2838 (1998).
Effective pyroelectric coefficients as large as 5 μC/cm2 °C, with peak responsivities at approximately 50 °C, were obtained from compositionally graded barium strontium titanate ferroelectric thin film devices formed on silicon using unbalanced magnetron sputter deposition. These effective pyroelectric coefficients are nearly two orders of magnitude larger than those observed from conventional pyroelectric thin film ferroelectric detectors.

t
hey even created tool to visualize hysteresis of ferroelectric material The EDU a unique educational tool for science and engineering education. The EDU is a fully functional test instrument for the non-linear electro ceramics like those used for industrial sensors and actuators. The EDU measures the hysteresis loops of packaged ferroelectric capacitors Radiant created specifically for the tester. Radiant provides a complete set of tutorials to guide the student in understanding non-linear materials and a set of recommended experiments for the students to work with the ferroelectric capacitors. External ports on the instrument allow students to build their own sensor and/or memory projects using ferroelectric components from Radiant and to control their projects using the EDU’s operating software.
The EDU
has a 20kHz arbitrary waveform generator and a 20kHz electrometer that run under the control of an elegant graphical data-acquisition program. The EDU architecture allows any laptop with a USB port to become a ferroelectric test instrument in less than a minute, making it a perfect teaching tool in student labs.
Was not that .that SR was using 20-35KHz?"We are going to get them by the balls" New Details of Ferroelectric Switching
http://www.aps.anl.gov/Science/Highlights/2004/ferroelectric_switching.htm1."X-rays penetrate right through materials, so we can look deep inside electronic devices,
Question:
Do we deal with some of Xray efect or ultraviolet efect when we use spark?
2.Polarization fatigue is a well known problem in ferroelectric capacitor technology.
In this case, the effect is believed to stem from migration of oxygen atoms to the electrode regionpolarization fatigue was qualitatively different when the switching was driven by lower-amplitude electric-field pulses (0.625 MV per cm peak) switching versus higher field pulses (1.2 MV per cm peak). Fatigue was observed in both regimes as the polarization-field hysteresis loops collapsed after repeated cycling with triangle wave pulses at 1 kHz. Low electric field fatigue was observed within 104 pulses as the PZT layer structure became pinned into an unswitchable state, which could be restored by exposure to higher field pulses.
