Control Methodology Of Pedestrian Kinematics Using The Active Hood Lift System

View page
US Patent:
20110282538, Nov 17, 2011
Filed:
May 13, 2010
Appl. No.:
12/779325
Inventors:
Atsutaka TAMURA - Blacksburg VA, US
Stefan DUMA - Blacksburg VA, US
Assignee:
Toyota Motor Engineering and Manufacturing North America, Inc. - Erlanger KY
International Classification:
B60R 21/34
G06F 7/00
B62D 25/10
US Classification:
701 29, 29618704, 180 6921
Abstract:
A method and device for use in pedestrian-vehicular collisions in which an active hood lift system is deployed to a first elevated lift position and maintained at the deployed position for an interval after which it is lowered, thereby controlling pedestrian impact kinetics and reducing forces that can result pedestrian injuries.

Whitewater Helmet Evaluation System And Method

US Patent:
20230045678, Feb 9, 2023
Filed:
Aug 3, 2022
Appl. No.:
17/817152
Inventors:
- Blacksburg VA, US
Stefan Duma - Blacksburg VA, US
Mark Begonia - Christiansburg VA, US
Steve Rowson - Blacksburg VA, US
International Classification:
G01M 7/08
G01P 15/00
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.

Methodology For Assessing The Biomechanical Performance Of Helmets

View page
US Patent:
20160021964, Jan 28, 2016
Filed:
Jul 22, 2015
Appl. No.:
14/806595
Inventors:
Stefan M. Duma - Blacksburg VA, US
Steven Rowson - Blacksburg VA, US
Craig McNally - Dublin VA, US
International Classification:
A42B 3/04
G01N 3/30
Abstract:
The present invention provides a method for testing a helmet that uses a risk function that incorporates both linear and rotational acceleration to predict the helmet's ability to prevent a concussion. In certain embodiments, the testing matrix includes 3 impact energy levels and 4 impact locations, for a total of 12 testing conditions per helmet.
