Sudden loading injuries to the low back are a concern. Current models are limited in their ability to quantify the time-varying nature of the sudden loading event. The method of approach used six males who were subjected to sudden loads. Response data (EMG and kinematics) were input into a system identification model to yield time-varying torso stiffness estimates. The results show estimates of system stiffness in good agreement with values in the literature. The average root mean square error of the model’s predictions of sagittal motion was equal to 0.1deg. In conclusion, system identification can be implemented with minimal error …

This paper details an evaluation of a tactile cueing system that was created to enhance the navigation of a complex route. The complexity of the task along with simultaneously challenging cognitive tasks also enabled the real-time assessment of cognitive state in various task load conditions. Honeywell has been working with the US Army's Future Force Warrior program to develop adaptive systems that will effectively manage the available cognitive resources used for information processing by the dismounted Soldier in highly dynamic, information rich environments. The appropriate allocation of cognitive resources is key to managing multiple tasks, focusing on the most important …
