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