Power meter circuit board

[Filespace]

OK, i cant remember which brand this came out(progress energy) of i will know later tonight when i get home i have the same one on my house. From what i have found so far there is a tilt detector on board and i see some test pads.
will get better imgs in a day or too

black boxey thing "rbs31" (upper right corner of board) is a tilt switch






Any thoughts?
