| 14 | Description: |
| 15 | This attribute returns a string with the physical location where |
| 16 | the motion sensor is placed. For example, in a laptop a motion |

| 24 | Description: |
| 25 | This attribute is exposed by the CrOS EC legacy accelerometer |
| 26 | driver and represents the sensor ID as exposed by the EC. This |
| 27 | ID is used by the Android sensor service hardware abstraction |
| 28 | layer (sensor HAL) through the Android container on ChromeOS. |
