|  | 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. |
