Abstract

A portable wireless communication terminal includes a sensor to detect a movement of the portable wireless communication terminal and output a first signal based on an acceleration of the movement and a second signal based on a velocity of the movement and a controller to control a hard disk drive (HDD) in response to both the first and second signals.

Claims

1. A portable wireless communication terminal comprising:

a sensor to detect a movement of the portable wireless communication terminal and output a first signal based on an acceleration of the movement and a second signal based on a velocity of the movement; and

a controller to control a hard disk drive (HDD) in response to both the first and second signals.

2. The portable wireless communication terminal of claim 1, further comprising an audio processor, the audio processor comprising an analog-to-digital converter (ADC) adapted to receive an audio signal, wherein the second signal is an analog signal and the ADC converts the second signal to a digital signal.

3. The portable wireless communication terminal of claim 1, wherein the controller comprises an analog-to-digital converter adapted to receive and convert the second signal to a digital signal.

4. The portable wireless communication terminal of claim 1, further comprising a second controller coupled between the first controller and the HDD to receive the first signal and control the hard disk drive in response to an output of the first controller.

5. The portable wireless communication terminal of claim 1, wherein the controller is adapted to determine whether the movement acceleration is over a threshold value.

6. The portable wireless communication terminal of claim 1, wherein the controller is adapted to determine, after determining that the movement acceleration is over a threshold value, whether to park the HDD based on the movement velocity.

7. The portable wireless communication terminal of claim 1, wherein the controller is adapted to determine whether to park the HDD based on the movement velocity.

8. The portable wireless communication terminal of claim 1, further comprising an RF module adapted to receive and transmit signals and coupled to the controller.

9. A method comprising:

detecting a movement of a portable wireless communication terminal and outputting a first signal based on an acceleration of the movement and a second signal based on a velocity of the movement; and

controlling a hard disk drive (HDD) in response to both the first and second signals.

10. The method of claim 9, further comprising the step of converting the second signal to a digital signal with an analog-to-digital converter (ADC) of an audio processor, wherein the ADC is adapted to receive an audio signal and the second signal is an analog signal.

11. The method of claim 9, further comprising the step of converting the second signal to a digital signal with an analog-to-digital converter (ADC) of a controller coupled to the HDD, wherein the second signal is an analog signal.

12. The method of claim 9, further comprising the step of controlling the HDD by using a second controller coupled between a first controller and the HDD, the second controller receiving the first signal and controlling the hard disk drive in response to an output of the first controller.

13. The method of claim 9, wherein the controlling step comprises determining whether the movement acceleration is over a threshold value.

14. The method of claim 9, wherein the controlling step comprises determining, after determining that the movement acceleration is over a threshold value, whether to park the HDD based on the movement velocity.

15. The method of claim 9, wherein the controlling step comprises determining whether to park the HDD based on the movement velocity.

16. The method of claim 9, further comprising receiving and transmitting signals with an RF module coupled to a controller for performing the step of controlling the HDD.
