Abstract: Various embodiments relating to methods for evaluating injury mitigation performance of helmets that are used for sports (e.g., whitewater kayaking and rafting) are described. In one embodiment, a method for evaluating injury mitigation performance of a helmet includes applying a first impact configuration to a first helmet and applying a second impact configuration to a second helmet of the same model as the first helmet. The method further includes generating acceleration data based on impacts that occur as part of the first impact configuration and the second impact configuration. The method further includes determining concussion risk values based on the generated acceleration data. The method also includes determining a concussion risk metric based on the concussion risk values and exposure values.

Abstract: A shock testing machine including: a test platform; a carriage for carrying the test platform; one or more rails movably supporting one or both test platform and the carriage; a stop for stopping the carriage in a testing direction; and a brake for decelerating the carriage after the carriage engages the stop. Wherein the brake includes: a braking member separate from the carriage, the braking member having braking material separated by a gap, the carriage configured to expose the braking member to the stop when the carriage moves past the stop in the testing direction; and an elongated member extending from the carriage, the elongated member extending through the gap, respectively, in the braking member such that a braking pressure is applied from the braking material to the elongated member to decelerate the carriage when a braking surface of the braking member engages a braking surface of the stop.

Abstract: A method of utility pole integrity assessment by distributed fiber optic sensing/distributed acoustic sensing (DFOS/DAS) employing existing telecommunications fiber optic cable as a sensor. The fiber optic cable is suspended aerially from a plurality of utility poles and a machine learning model is developed during training by mechanically exciting the utility poles. Once developed, and in sharp contrast to the prior art, the machine learning model—in conjunction with DFOS/DAS operation—determines an integrity assessment for a plurality of the utility poles aerially suspending the fiber optic cable from a mechanical impact of a single pole.

Abstract: According to one embodiment, a structure evaluation system includes at least three or more sensors, a position locator, and an evaluator. The three or more sensors are arranged on surfaces different from a surface to which an impact is applied with respect to a structure at different intervals in a first direction of the structure and a second direction orthogonal to the first direction and detects elastic waves generated from the structure. The position locator locates a position of a source in which the elastic waves are generated on the basis of the elastic waves detected by each of the three or more sensors. The evaluator evaluates a deterioration state of the structure on the basis of information based on a position location process of the position locator and information indicating a position where the impact is applied.
