Device to reduce traumatic brain injury
First Claim
1. A device for reducing traumatic brain injury, the device comprising:
- a first sensor coupled to a head component configured to measure a motion value of a user'"'"'s head as a result of motion of the head component and to generate a sequence of real-time measured samples;
a linkage element configured to connect the head component to a body component, the linkage element switchable between a first state in which the linkage element is relatively flexible and a second state in which the linkage element is relatively rigid based upon a locking signal; and
a processing element configured to receive the measured samples,calculate a plurality of dynamic concussion thresholds, each dynamic concussion threshold associated with one of a plurality of sequential, time-based array cells, each array cell including a mean of historically-collected measured samples and a standard deviation of historically-collected measured samples from the first sensor, such that each dynamic concussion threshold is calculated as a sum of the mean and the standard deviation for the associated array cell,compare a first measured sample to a first dynamic concussion threshold, a second measured sample to a second dynamic concussion threshold, and so forth in sequence, andgenerate the locking signal when each one of a predetermined number of successive measured samples is greater than the corresponding successive dynamic concussion thresholds.

Abstract
A device for reducing traumatic brain injury comprises a first sensor, a first linkage element, and a processing element. The first sensor is coupled to a head component and configured to measure an acceleration of a user'"'"'s head and to generate a sequence of real-time measured samples. The first linkage element is configured to connect the head component to a body component and is able to switch between a first state in which it is relatively flexible and a second state in which it is relatively rigid. The first linkage element is switched from its first state to its second state by a locking signal. The processing element is configured to receive the real-time measured samples and to generate the locking signal when each of a portion of the real-time measured samples is greater than one of a corresponding portion of a plurality of dynamic concussion thresholds.
