Abstract

A system for detecting vehicular motion to blank a computer screen. The system includes filtering the motion to determine whenever the motion is consistent with vehicular motion. The system includes communicating the vehicular motion to a computer. The system includes blanking the screen of the computer whenever detecting vehicular motion and blanking the screen of the computer whenever the motion detector is not attached the portable computer.

Claims

1. A system comprising the steps of:

a. detecting motion;

b. filtering the motion to determine whenever the motion is consistent with vehicular motion;

c. communicating the vehicular motion to a computer;

d. blanking the screen of the computer after the step of communicating the vehicular motion; and

e. blanking the screen of the computer whenever the step of communicating fails.

2. The system of claim 1 wherein:

a. the step of detecting motion occurs without altering the vehicle.

3. The system of claim 1 wherein:

a. the step of blanking the screen occurs without interfering with any other operations of the computer.

4. The system of claim 1 wherein:

a. the steps of blanking the screen permits showing portions of the screen related to operating the vehicle.

5. The system of claim 1 further comprising the step of:

a. profiling the vibration characteristics of the vehicle;

b. wherein the step of filtering the motion comprises the step of reducing noise using the vibration characteristics.

6. The system of claim 1 wherein:

a. the steps of blanking the screen further comprises the step of recording the date and time.

7. The system of claim 1 further comprising the step of:

a. profiling the vibration characteristics of the vehicle;

b. wherein the step of filtering the motion comprises the step of reducing noise using the vibration characteristics;

c. wherein the step of detecting motion occurs without connecting directly to the vehicle;

d. wherein the steps of blanking the screen occurs without interfering with any other operations of the computer; and

e. wherein the steps of blanking the screen permits showing portions of the screen related to operating the vehicle.

8. A system comprising:

a. a motion detector to detect motion;

b. a filter to filter the motion to determine whenever motion is consistent with vehicular motion of a vehicle;

c. a communication interface operably connected between the motion detector and a computer to transmit the signals of the filter between the motion detector and the computer; and

d. a program on the computer to blank the screen of the computer whenever the filter determines vehicular motion or whenever the computer fails to receive signals from the motion detector.

9. The system of claim 8 wherein:

a. the motion detector is not permanently attached to the vehicle.

10. The system of claim 8 wherein:

a. the communication interface comprises a length of cable sufficient to dampen any vibration caused by the operation of the computer hardware.

11. The system of claim 8 wherein:

a. communication interface comprises a universal serial bus.

12. The system of claim 8 wherein:

a. the program does not interfere with any other operation of the computer.

13. The system of claim 8 wherein:

a. the program cannot be removed or disabled from the computer without administrative access rights for the operating system of the computer.

14. The system of claim 8 wherein:

a. the motion detector comprises a tilt and vibration sensor;

b. the communication interface comprises a universal serial bus;

c. the filter comprises a reprogrammable microprocessor.

15. The system of claim 8 wherein:

a. the program comprises

i. a blanker module to blank the screen, and

ii. a watchdog module to watch the blanker module and to restart the blanker module whenever the blanker module is not executing on the computer.

16. The system of claim 15 wherein:

a. the program further comprises policies to allow the blanker module to display a portion of the screen related to operating the vehicle.

17. The system of claim 16 wherein:

a. the program does not interfere with any other operation of the computer;

b. the program cannot be removed or disabled from the computer without administrative rights;

c. the motion detector comprises a tilt and vibration sensor;

d. the motion detector is not fixedly attached to the vehicle;

e. the motion detector does not have a preferred orientation;

f. the communication interface comprises a universal serial bus;

g. the communication interface comprises a length of cable sufficient to dampen any vibration caused by the operation of the computer hardware;

h. the communication interface comprises a universal serial bus;

i. the filter comprises a reprogrammable microprocessor; and

j. the computer comprises a laptop computer.

18. A system comprising:

a. motion-detecting means for detecting motion;

b. filtering means for filtering the motion to determine whenever the motion is consistent with vehicular motion;

c. communicating means for communicating the vehicular motion to a computer;

d. blanking means for blanking the screen of the computer after the step of communicating the vehicular motion and for blanking the screen of the computer whenever the step of communicating fails.

19. The system of claim 18 further comprising:

a. profiling means for profiling the vibration characteristics of the vehicle;

b. wherein the filtering means comprises noise reducing means for reducing noise using the vibration characteristics.

20. The system of claim 19 wherein:

a. the motion-detecting means operates without permanently attaching to the vehicle;

b. the blanking means operates without interfering with any other operations of the computer; and

c. the blanking means comprises profiling means for profiling portions of the screen for display during operating of the vehicle.
