This report presents an evaluation of a new deflection measuring system. Briefly, the optically-based RibEye system developed by Robert A. Denton, Inc., for the 50th percentile male Hybrid III dummy is capable of providing deflections at 12 locations within the ribcage. Illumination from each light emitting diode (LED) positioned on the inside rib surface or sternum is captured by two sensors placed on either side of the spine box in the dummy. Deflections can be derived from processed optical signals, gathered along the x and y, i.e., frontal and side (antero-posterior and lateral) directions. Quasi-static and dynamic tests were done during the evaluation process. |
