609a642b7SGe GaoDescription:
709a642b7SGe Gao		This is mounting matrix for motion sensors. Mounting matrix
809a642b7SGe Gao		is a 3x3 unitary matrix. A typical mounting matrix would look like
909a642b7SGe Gao		[0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be
1009a642b7SGe Gao		easy to tell the relative positions among sensors as well as their
1109a642b7SGe Gao		positions relative to the board that holds these sensors. Identity matrix
1209a642b7SGe Gao		[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly
1309a642b7SGe Gao		aligned with each other. All axes are exactly the same.
