Device and system to reduce traumatic brain injury
First Claim
1. A method of reducing traumatic brain injury comprising the steps of:
- generating sensor measurements from a first sensor coupled to a head component attached to the head of a user in response to an impact to the user which causes motion of the head;
determining if a value of the sensor measurements is greater than or equal to an injury level value;
transmitting a locking signal to a linkage element when the value of the sensor measurements is greater than or equal to the injury level value;
switching a state of the linkage element connecting the head component to a body component attached to the body of the user when the locking signal is received from a relatively flexible state to a relatively rigid state to stop motion of the head about the neck toward either shoulder of the user; and
wherein links of the linkage element are operable to rotate with respect to one another and switching the state of the linkage element from the relatively flexible state to the relatively rigid state stops rotational motion of the linkage element.

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 as a result of an impact on the head component and to generate corresponding first sensor measurements. 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 first sensor measurements and to generate the locking signal when a value of the first sensor measurements is greater than or equal to an injury level.

9. A method of reducing traumatic brain injury comprising the steps of:
-
generating sensor measurements from a first sensor coupled to a head component attached to the head of a user in response to an impact to the user which causes motion of the head; determining if a value of the sensor measurements is greater than or equal to an injury level value to indicate the presence of a potentially dangerous and harmful impact force to the head; transmitting a locking signal to a linkage element when the value of the sensor measurements is greater than or equal to the injury level value to indicate the presence of a potentially dangerous and harmful impact force to the head, the linkage element including a first anchor configured to rigidly couple to the head component, a second anchor configured to rigidly couple to the body component, a plurality of links coupling the first anchor to the second anchor the links including a first end link coupled to the first anchor and configured to rotate and pivot with respect to the anchor, a second end link coupled to the second anchor and configured to rotate and pivot with respect to the second anchor, and a middle link coupled to the first anchor and the second anchor and configured to rotate and pivot with respect to both the first anchor and the second anchor; and switching a state of the linkage element connecting the head component to a body component attached to the body of the user when the locking signal is received from a relatively flexible state to a relatively rigid state, such that motion is stopped between the first anchor and at least one link and between the second anchor and at least one link. - View Dependent Claims (10, 11, 12, 13)

generating sensor measurements from a first sensor coupled to a head component attached to the head of a user in response to an impact to the user which causes motion of the head; determining if a value of the sensor measurements is greater than or equal to an injury level value to indicate the presence of a potentially dangerous and harmful impact force to the head; transmitting a locking signal to a linkage element connecting the head component to a body component attached to the body of the user when the value of the sensor measurements is greater than or equal to the injury level value to indicate the presence of a potentially dangerous and harmful impact force to the head; generating a magnetic field from a first component of the linkage element to a second component of the linkage element to lock the relative positions of the first component and the second component when the locking signal is received; and wherein the magnetic field is generated from the first component of the linkage element to strongly attract the second component of the linkage element. - View Dependent Claims (15, 16, 17, 18, 19)
