Helmet system and methods

摘要

One variation of a method for recording accidents includes: in a first mode, capturing a second video frame at a second time, storing the second video frame with a first sequence of video frames, captured over a buffer duration, in local memory in the helmet, removing a first video frame captured outside of the buffer duration from local memory, and rendering a subregion of the second video frame on a display arranged within the helmet; in response to detection of an accident involving the helmet, transitioning from the first mode into a second mode; in the second mode, capturing a second sequence of video frames, and storing the second sequence of video frames exceeding the buffer duration in local memory; and generating a video file from the first sequence of video frames and the second sequence of video frames stored in local memory.

1. A method comprising:
in a first mode:
with a camera arranged on a helmet, capturing a second video frame at a second time;storing the second video frame with a first sequence of video frames in local memory in the helmet, the first sequence of video frames captured over a period of time corresponding to a buffer duration;in response to capturing the second video frame, removing a first video frame from local memory, the first video frame captured at a first time preceding the second time by a duration exceeding the buffer duration; andat approximately the second time, rendering a subregion of the second video frame on a display arranged within the helmet; based on an output of an inertial sensor arranged within the helmet, detecting an accident involving the helmet; in response to detecting the accident, transitioning from the first mode into a second mode; in the second mode:
with the camera, capturing a second sequence of video frames; andstoring the second sequence of video frames in local memory in the helmet, the second sequence of video frames corresponding to a period of time exceeding the buffer duration; and generating a video file from the first sequence of video frames and the second sequence of video frames stored in local memory.
