Force is a vector, so "vector" may be optional, unless you want to emphasize its directionality (vector nature).

For the BIO-Helmet, the main pins of interest are the Xout, Yout, and Zout. These
pins will output a certain voltage based on the force of an impact to the helmet
which can then be used to create an impact force vector.

The neurological effects observed were momentary stunning and disorientation, which lasted no more than 2 minutes. In one case, this response was noted at an impact level as low as 17.4 G, where the impact force vector was in orientation 17

The present invention relates to a helmet comprising a shell; and a force redirection member disposed between the shell and a head when the helmet is worn, the member configured to redirect a force impacting on the shell to a direction different from the original direction of the impact on the shell. The present invention also relates to a method to decrease the risk of injury to a person wearing a helmet, caused by rotational forces when the helmet is impacted by a force characterized by a specific direction having a first vector, the method comprising redirecting the force into a different direction having a second vector, wherein the direction of the second vector is selected to reduce the risk of a specified injury associated with acceleration of the head in the direction of the first vector.

A force redirection member 300 is retained within bladder 202 . With reference to FIGS. 5 a and 5 b , member 300 is configured to redirect an impact force (F) applied to outer shell 102 adjacent to spacer 200 . The redirection causes outer shell 102 to rotate independently of liner 104 and/or to attenuate rotation of shell 102 , and/or to cause liner 104 to rotate in a different direction from shell 102 .
