Drop countermeasures for electronic device
First Claim
Patent Images
1. An electronic device comprising:
- a housing;
a motion sensor configured to sense motion of the housing;
a processor configured to determine a drop event; and
a countermeasure system aligned with an unstable inertial axis of the electronic device, the countermeasure system comprising an actuator coupled to a mass, wherein the mass is operable by the actuator to adjust an attitude of the electronic device to avoid impact with an impact sensitive component of the electronic device in response to determining the drop event.

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.

8. A method comprising:
-
sensing motion of a housing of an electronic device indicative of a drop event; and in response to sensing the motion indicative of the drop event, actuating a mass aligned with an unstable inertial axis of the electronic device to modify an attitude of the electronic device to reduce a likelihood of impact with an impact sensitive component of the electronic device. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An electronic device comprising:
-
a processor configured to detect a drop event; and a mass configured to be rotated by an actuator about an axis that is aligned with an unstable inertial axis of the electronic device to cause the electronic device to move from a current attitude towards a preferred attitude less likely to result in damage to an impact sensitive component of the electronic device than the current attitude; wherein the processor is configured to cause the mass to be rotated by the actuator in response to the drop event. - View Dependent Claims (16, 17, 18, 19, 20)
