FALLING STATE DETERMINATION FOR DATA STORAGE DEVICE |
| 摘要 |
Determination of when an electronic device such as a data storage device (DSD) is falling. An input is received indicating an acceleration of the electronic device during a time period. A classifier function is calculated using the input and it is determined whether the electronic device is falling based on a calculated value of the classifier function. During a calibration process, acceleration values are recorded representing a plurality of actual falls and a plurality of false falls of the electronic device. Weight values are set for a weighted classifier function using the recorded acceleration values and the weighted classifier function is stored in a memory of the electronic device. |

1. A data storage device (DSD) comprising:
a memory for storing data; and a controller configured to:
receive an input indicating an acceleration of the DSD during a time period;calculate a classifier function using the input; anddetermine whether the DSD is falling based on a calculated value of the classifier function. |
