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