^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) Description:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		This is mounting matrix for motion sensors. Mounting matrix
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		is a 3x3 unitary matrix. A typical mounting matrix would look like
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		[0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		easy to tell the relative positions among sensors as well as their
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		positions relative to the board that holds these sensors. Identity matrix
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 		[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		aligned with each other. All axes are exactly the same.
