Abstract

An electronic device comprises a housing, a motion sensor configured to sense motion of the housing, and a processor configured to determine an impact geometry based on the motion. A countermeasure system comprises an actuator coupled to an actuated member. The actuated member is operable by the actuator to modify the impact geometry, so that impact energy is redirected away from an impact sensitive component of the electronic device to an energy absorbing component of the electronic device.

Claims (34)

1. An electronic device configured to magnetically attach to a cover, the electronic device comprising:

a housing;

a display mounted in the housing, wherein the cover overlaps the display when attached to the electronic device;

a sensor mounted in the housing; and

a magnet mounted in the housing, wherein the magnet is configured to reverse polarity and at least partially detach the cover based on a measurement from the sensor.

2. The electronic device defined in claim 1 , further comprising:

a processor, wherein the processor is configured to determine a position of the electronic device based on the measurement from the sensor.

3. The electronic device defined in claim 2 wherein the sensor is a camera.

4. The electronic device defined in claim 2 wherein the sensor is a motion sensor.

5. The electronic device defined in claim 4 wherein the magnet is configured to reverse polarity and at least partially detach the cover when the processor determines that the electronic device has been dropped.

6. The electronic device defined in claim 1 wherein the magnet is configured to attach the cover to a rear surface of the housing.

7. The electronic device defined in claim 1 wherein the magnet is configured to attach the cover to a front surface of the electronic device, adjacent to the display.

8. The electronic device defined in claim 1 wherein the cover comprises multiple cover panels and wherein the magnet is configured to reverse the polarity to detach at least one of the cover panels from the electronic device.

9. The electronic device defined in claim 8 wherein the cover comprises an actuator and wherein the actuator is configured to fold the cover panels after at least one of the cover panels has been detached from the electronic device.

10. The electronic device defined in claim 1 wherein the magnet is configured to completely detach the cover from the electronic device.

11. An electronic device configured to magnetically attach a cover, the electronic device comprising:

a housing;

a display in the housing, wherein the cover overlaps the display when the cover is magnetically attached to the electronic device;

a motion sensor in the housing; and

a magnet in the housing, wherein the magnet is configured to at least partially detach the cover in response to a measurement from the motion sensor.

12. The electronic device defined in claim 11 wherein the magnet is configured to reverse polarity and at least partially detach the cover in response to the measurement from the motion sensor.

13. The electronic device defined in claim 12 , further comprising:

a processor, wherein the processor is configured to determine when the electronic device has been dropped based on the measurement from the sensor and wherein the magnet is configured to detach the cover in response to the processor determining that the electronic device has been dropped.

14. The electronic device defined in claim 12 wherein the magnet is a bimetallic strip.

15. The electronic device defined in claim 11 wherein the cover comprises multiple cover panels and wherein the magnet is configured to at least partially detach one of the multiple cover panels in response to the measurement from the motion sensor.

16. The electronic device defined in claim 11 wherein the motion sensor comprises a sensor selected from the group consisting of: a gyro sensor, an accelerometer, and a magnetic sensor.

17. The electronic device defined in claim 11 wherein the magnet is configured to attach the cover to a rear surface of the housing.

18. The electronic device defined in claim 11 wherein the magnet is configured to attach the cover to a front surface of the electronic device, adjacent to the display.

19. An electronic device having a housing and configured to magnetically attach to a cover, the electronic device comprising:

a display mounted in the housing;

a motion sensor mounted in the housing;

a processor in the housing, wherein the processor is configured to determine when the electronic device has been dropped based on data from the motion sensor; and

a magnet mounted in the housing, wherein the processor is configured to reverse a polarity of the magnet to at least partially detach the cover when the processor determines that the electronic device has been dropped.

20. The electronic device defined in claim 19 wherein the magnet is a bimetallic strip having adjacent magnetic portions with alternating polarity.
