| 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. |
