Abstract

An electronic device includes one or more screens, multiple screen protectors moveable between a retracted position and extended position where they extend above the screen to create a gap, and one or more sensors. When the sensor detects a drop event, the screen protectors move from the retracted to extended position, functioning as a shock absorber and preventing the screen from connecting with a surface that the electronic device contacts. In some implementations, the screen protectors may be multiple tabs that may be moved between the retracted and extended positions by one or more motors and/or other actuators coupled to one or more pinions. Such tabs may be formed of various flexible and/or rigid materials such as plastic, plastic film, polyethylene terephthalate or other polymers, metal, thin film metal, combinations thereof, and/or other such materials.

First claim

We claim:

1. A system for active screen protection for an electronic device including at least one screen, the system comprising:
multiple screen protectors rotationally moveable between at least an extended position and a retracted position below the at least one screen, wherein the multiple screen protectors extend above and overlap the at least one screen in the extended position to create at least one gap between the at least one screen and the multiple screen protectors, and wherein the at least one screen overlaps the multiple screen protectors when the multiple screen protectors are in the retracted position; and
at least one sensor that detects when the electronic device is subject to a drop event;
wherein the multiple screen protectors rotationally move from the retracted position to the extended position when the at least one sensor detects that the electronic device is subject to the drop event.

2. The system of claim 1 , wherein a first portion of each of the multiple screen protectors is flush with the at least one screen in the retracted position and a second portion of each of the multiple screen protectors is positioned below the at least one screen in the retracted position.

3. The system of claim 1 , wherein the multiple screen protectors comprise multiple tabs.

4. The system of claim 3 , wherein the multiple tabs comprise at least one of plastic, plastic film, polyethylene terephthalate, a polymer, thin metal, or metal.

5. The system of claim 3 , wherein the multiple tabs comprise at least one tab positioned at each corner of the at least one screen.

6. The system of claim 1 , wherein the multiple screen protectors absorb shock when the electronic device impacts a surface as a result of the drop event.

7. The system of claim 6 , wherein the at least one gap is positioned between ends of the multiple screen protectors and the surface after the drop event.

8. The system of claim 1 , wherein the at least one sensor comprises at least one accelerometer, gyroscope, inertial sensor, camera, altitude sensor, global positioning system sensor, or motion sensor.

9. The system of claim 1 , wherein the multiple screen protectors rotationally move from the extended position to the retracted position when at the at least one sensor detects that the drop event is over.

10. The system of claim 1 , further comprising at least one motor that rotationally moves the multiple screen protectors between the extended position and the retracted position.

11. The system of claim 10 , wherein the at least one motor rotationally moves the multiple screen protectors by moving at least one pinion.

12. The system of claim 11 , wherein the at least one pinion mates with multiple slots coupled to the multiple screen protectors.

13. The system of claim 10 , wherein the at least one motor comprises multiple motors and each of the multiple screen protectors is rotationally moved by a different one of the multiple motors.

14. The system of claim 10 , wherein the at least one motor comprises multiple motors and at least one of the multiple motors rotationally moves at least two of the multiple screen protectors.

15. The system of claim 1 , further comprising a plurality of apertures in the electronic device, wherein each of the multiple screen protectors passes through a respective one of the apertures to move from the retracted position to the extended position.

16. The system of claim 1 , wherein the multiple screen protectors rotationally move from the extended position to the retracted position in response to at least one user input.

17. The system of claim 1 , wherein the multiple screen protectors rotationally move from the extended position to the retracted position upon expiration of at least one timer after detection of the drop event.

18. The system of claim 1 , wherein the multiple screen protectors rotationally move from the extended position to the retracted position when at the at least one sensor detects that the electronic device is retrieved after the drop event.

19. An electronic device, comprising:
a housing that separates an interior of the housing from an exterior of the housing;
at least one screen mounted in the housing;
a plurality of apertures in the housing around the periphery of the at least one screen;
multiple screen protectors moveable between at least an extended position and a retracted position, the multiple screen protectors extend above the at least one screen in the extended position to create at least one gap, wherein the multiple screen protectors are located entirely within the interior of the housing when the multiple screen protectors are in the retracted position; and
at least one sensor that detects when the electronic device is subject to a drop event;
wherein each of the multiple screen protectors passes through a respective one of the apertures to move from the interior of the housing in the retracted position to the exterior of the housing in the extended position when the at least one sensor detects that the electronic device is subject to the drop event.

20. A method for active screen protection, the method comprising:
detecting when an electronic device that includes at least one screen is subject to a drop event utilizing at least one sensor; and
rotationally moving multiple screen protectors from a retracted position below the at least one screen to an extended position in response to detection of the at least one drop event, wherein the multiple screen protectors extend above the at least one screen in the extended position to create at least one gap, and wherein the at least one screen overlaps the multiple screen protectors when the multiple screen protectors are in the retracted position.
