I am not so intelligent when it comes to physics and mathematics mixed with analog circuits. Does anyone has any idea about this circuit and what it is doing ? Is this what I am guessing ?
Anyother ideas about how to measure angles ?

Hi Farshid,
I wondered where you had got to ! Finished with the army ?

My guess is they have the other accelerometer positioned [i]backwards[/i] to the first, then a positive acceleration on one appears as a negative acceleration on the other, and when the outputs are summed , they are zero from the acceleration. I suspect that you may also get a free amplification of the angle result.
