Abstract

An apparatus, method, computer program product, and/or system are described that determine an event, actuate a cushioning element in response to the determining the event, the cushioning element including one or more tension-bearing members, and dissipate at least some of an energy associated with a collision based on deforming at least one of the tension-bearing members during the collision, the deforming including substantially inelastically stretching the at least one of the tension-bearing members. Other example embodiments are also provided relating to actuatable cushioning elements.

10. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on at least a relative location, a relative velocity, and a relative acceleration of the first object with respect to the second object.

11. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on at least a relative location, a relative velocity, a relative orientation, and a relative angular velocity of the first object with respect to the second object.

12. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on at least a relative acceleration and an angular acceleration of the first object with respect to the second object.

13. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on at least one of:

14. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on a relative velocity of the first object with respect to the second object.

15. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on a relative acceleration of the first object with respect to the second object.

16. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on a relative orientation of the first object with respect to the second object.

17. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on a relative angular velocity of the first object with respect to the second object.

18. The method of claim 1 wherein the determining an event comprises:

determining that a collision between a first object and a second object is likely to occur based on a relative angular acceleration of the first object with respect to the second object.
