Front and rear drive power distribution control device for vehicle
Just found this fun little patent application and believe me reading it makes you see why a torque measuring device has an awful lot to be said for it. If I understood the engineering situation more thoroughly I might be feeling sorry for these inventors. I am pretty sure though they are not a threat to our product.

Thanks Westwell for the post. I know were I am a bit airyfairy and this was one of the those places.
