an inflation device configured to inflate an airbag coupled to a helmet;

a processing circuit configured to;

receive object data regarding an object;

control operation of the inflation device based on the object data; and

a retraction device configured to retract the airbag.

2. The system of claim 1, wherein the object data comprises an indication of at least one of a location, a velocity, a relative location, a relative velocity, a range, a predicted impact location, a predicted impact time, a closing rate, a size, a shape, and an orientation.

3. The system of claim 1, wherein the object data includes data regarding a predicted potential impact between the object and the helmet.

6. The system of claim 1, wherein the processing circuit is further configured to receive helmet data regarding the helmet, and control operation of the inflation device based on the helmet data.

7. The system of claim 6, wherein the helmet data includes an indication of at least one of a location, a velocity, an orientation, an acceleration, a size, and a shape of the helmet.

8. The system of claim 1, further comprising a plurality of fibers coupled to the airbag and configured to retract the airbag.

9. The system of claim 8, wherein the processing circuit is configured to selectively retract the plurality of fibers to retract the airbag.

10. The system of claim 8, further comprising a spring mechanism coupled to the plurality of fibers and configured to retract the fibers after inflation of the airbag.
